Medical Conditions You Can Inherit From Your Parents

Inheritable medical conditionsThere are many diseases and health concerns that a person can inherit from their parents; however, inheriting a mutated gene from one parent doesn’t necessarily mean that you will be at risk for a certain disease. Keep in mind genetic disorders are caused by the mutation of a gene. In some cases this genetic mutation can be transferred to a child. For a genetic disorder to transfer to a child, depends on the consistency of inheritance for the disorder. Continue reading

Is There A Genetic Link To Bipolar Disorder?

The causes of bipolar disorder are not yet very clear to the medical community but a lot has been learned about the condition in the past decade. From the emotional highs to the lows (and everything in between these extremes), doctors now have a good understanding of how this condition manifests.

There are very many questions regarding whether or not there is a genetic connection that predisposes people to developing bipolar disorder. A number of researchers have set out to investigate this very matter and the findings have been eye-opening.

Twins and Bipolar Disorder
In a study investigating the occurrence of bipolar disorder in identical twins, findings established that there is a high likelihood that if one of those twins develops the disease, the other twin will also develop it. That was not the case with another sibling to the identical twins so the twins scenario points to genetics playing a big role in how this conditions manifests in families.

Dr. Andrew Campbell, a plastic surgeon, narrated an experience of a distraught patient that approached him to carry out a procedure like this on her that very day. Noting the irregularity of her request, he patiently took her through what the process entailed and her hysterical condition led him to ask questions that brought to light the fact that she had bipolar disorder, just like her identical twin sister.
That patient’s example illustrates how the condition can lead sufferers to take rash actions and if no professionals are available to help them, they could potentially harm themselves.

Children of Parents with Bipolar Disorder
Researchers at Stanford University looked into the incidence of bipolar disorder in children born to a parent or parents that had the disease. They found that if one of the parents had the disease, there was a more than 50% chance that the children would also develop it.

In fact, there was a greater likelihood that the children would get a mental disorder such as depression, ADHD, or low grade depression that is chronic. In parents that had ADHD in their childhood, researchers found that such parents had a very high likelihood of having children that had bipolar disorder rather than attention deficit hyperactivity disorder. The more relatives there are with affective disorders, the higher the chance that others in that family would suffer from those conditions.

This connection does not only stop at children. Even other relatives become prone to major mental disorders if there is someone in the extended family that has bipolar disorder.

Final Thoughts
Much as the causes of bipolar disorder are not clearly understood, there is a lot that can be done to help sufferers get relief from the symptoms of the disease. The fact that a genetic link exists in showing who is likely to develop the disease should be seen as an early warning signal so that family members can be quickly helped when the disease does show up.

It is therefore important to keep you doctor informed if a case of bipolar disorder exists in the family so that the doctor can advise you on how best to keep yourself in good health should you start showing signs of affective diseases.

Did Genes from Mom Give You Early Wrinkles?

If it seems like you’re getting crow’s feet and fine lines earlier than your friends, it may be mom’s fault. Scientists have recently found a set of genes passed down from our mothers that influences aging. When we get defective genes, we suffer from premature aging. This includes wrinkles as well as a shorter lifespan. Scientists also found that damage to the mitochondria, which turn food into energy, accelerates age-related health conditions.

After performing experiments on mice, a team of researchers from Germany and Sweden discovered that defective mDNA causes serious genetic disease, but even mild damage accelerates aging.

This is because the aging that we see and feel is really the result of many types of cell damage. Most of this damage comes from our lifestyle and environmental factors, but our genes also play a big role. There are three causes of aging skin: genetic aging, environmental aging (such as smoking or sun damage) and hormonal aging. All three cause collagen to break down over time, weakening elastin in the skin and causing skin to become lax with wrinkles and lost volume.

Genetic aging is natural and occurs over time. Some people are simply predisposed to developing wrinkles earlier than average, while some are blessed with genes that keep them looking younger than their age. Some people are so lucky they can maintain youthful skin just based on genetics, while most have to turn to skincare products, cosmetic surgery and lifestyle changes.

Defective mDNA plays a role in many age-related problems, including heart disease and dementia. mDNA is also more susceptible to damage than regular DNA, they discovered.

Researchers still aren’t sure how big a role damaged mDNA from mom plays in aging, but this research and more studies to come may one day help find a way to slow down aging.

The good news is just about 10% of how your skin ages is genetic. You do have control over how you take care of your skin, including staying out of the sun, avoiding smoking and using moisturizer, according to Dr. Alexander S. Donath, MD, who performs procedures like this in Ohio. Even if you get get genes for early facial aging, there are steps you can take to turn back the hands of time.

You can help counteract genetic aging by drinking plenty of water, using exfoliants to clean your skin and changing your lifestyle. Eat a diet rich in antioxidants like fruits and vegetables, give up smoking for good and wear sunscreen every day — even when it’s cloudy — to fight back against those genes you get from mom. Keep in mind the most common causes of premature facial aging, aside from genetics:

1. Smoking. Smoking is a toxin to your skin, and just about the worst thing you can do for your skin because it harms your body’s ability to heal itself. If you quit smoking, you can help undo some of the damage that’s been done to improve your skin tone and clarity.
2. Not wearing sunscreen. 90% of wrinkles come from sun exposure. The best way to maintain a youthful appearance is staying out of the sun and wearing sunscreen.
3. Not exercising. Exercise gives you that healthy glow because it dilates blood vessels in the skin and sends nutrient-rich blood to the area. Aim for 30 minutes of aerobic exercise three times a week.

What You Should Have In Mind As You Go For Genetic Tests

Medical diagnostics has made such huge strides in the recent past. It is now possible to diagnose several conditions long before they make their presence known. This allows the individual to plan accordingly so that once the condition sets in, they are ready for it.

With that said, what should one have in mind as they make the decision to go and have some genetic tests run?

Probable Cause.
Before you go out to test whether or not a certain condition is genetic or not, there should be probable cause for you to have that suspicion. If, for instance, several people in your family tree have suffered from that condition (such as sickle cell anemia), you have all the reasons you need to have your DNA screened for that condition so that you can make some decisions regarding your future.

What Are The Costs?
Genetic tests can be quite expensive so before you have them run you should be aware of what those specific tests will cost you, and how you will meet that cost. This is particularly important given that insurance will not in most cases cover all those fees so you must have a plan regarding how you will make up the difference (if you have medical insurance) or pay the full fee (if you have no insurance cover).

Be Prepared For Any Outcome.
It is important to talk to a genetics counselor before you undergo the tests, and after you undergo the tests and they are positive for that condition that you wanted investigations to be carried out.

This counseling is important for several reasons. It can point you to the right experts to see. It can help you come to terms with the positive results that you receive and it can also help you to plan your next steps. You should therefore go for genetic tests when you know the results can swing either way, and be prepared to take whatever comes with those results.

Be Ready To Make Changes.
Before you go for genetic tests, ensure that you are ready to make changes that are necessary if the tests turn out to be positive for that condition. Those changes may include matters like reviewing your prospective spouse or deciding to have kids that will most certainly suffer from the condition you have both tested positive for.

Other changes may include matters of your career as certain lines of work may trigger the onset of the condition for which you have tested positive. A case in point are muscle degenerative conditions; if you are a pro athlete, chances are high that the condition will set in early so you have to be prepared to change career in order to delay its onset.

Summing it up…
Facial plastic surgeons at The Glasgold Group, who perform cosmetic and reconstructive procedures like this http://GlasgoldGroup.com/facenecklift.html, say that genetic tests even help them, too. Cleft lips are some of the conditions where they intervene and when a patient got it due to genetic factors, they advise the family to be on the lookout for other kids that may have the problem.

Genetic testing is therefore of great value to us all and we should make it a part of the tests that we undergo from time to time.

The Genetic Basis for Keloid Scarring and Treatment Options

Our genes truly define us; they help define our personality, thought process, appearance, and how our bodies function. Our genes can also make us more prone to certain medical conditions, or affect the way our bodies heal.

Keloid scarring is a fairly common problem, and new evidence now shows a genetic component for this condition. Keloids are growths of extra scar tissue where the skin has healed itself. Keloids may form from acne, burns, chickenpox, minor scratches or serious trauma, and they are more common in people aged 10 through 20, but they can happen to anyone.

Researchers have found that keloids tend to run in families, and they are most common among people with darker skin, particularly African Americans. So far, no single gene mutation has been found to be responsible for keloid disease, but its present in twins and the fact that it runs in families and is more common among people of certain ethnicities presents a strong case for a genetic cause. What we do know is genetic predisposition affects the quality and level of the scar tissue formed in a wound.

Who Gets Keloids?
Keloid disease results in abnormal wound healing, which may leave patients with disfiguring scars. Darker skinned people have a higher predisposition to developing keloids and it affects about 4-6% of people, and up to 16% of black Africans. Caucasians of northern European ancestry, on the other hand, have an incidence of keloid scarring that is less than a tenth of a percent.

Individuals who are genetically susceptible to keloids do not always develop them. There are also several congenital syndromes associated with keloid disease, including Rubinstein-Taybi syndrome, Geominne syndrome and Ehlers-Danlos syndrome.

Treatment for Keloids
While most keloid scars are benign and do not require treatment, they can require removal or treatment if they are located in an area that restricts movement or causes disfigurement. According to Dr. Batniji, who appears in this video, the decision to treat a keloid depends on the symptoms associated with its development and its location, and the risk of keloids must be considered before performing any number of procedures, such as this.

Cortisone injections are a common treatment for keloids, as injections are safe and usually not very painful. Keloids are injected with cortisone once a month until maximum benefit is achieved to flatten the keloid, but it can also make the keloid redder, which may then require laser treatment.

Laser treatment is effective at flattening keloids and reducing the redness, although laser treatment can be expensive and it is rarely covered by insurance. Some dermatologists use cryotherapy to freeze keloids with liquid nitrogen, which may flatten the scar but it often darkens the area.

Finally, surgical removal is a possibility. Dr. Batniji stresses that this is risky, because cutting into a keloid can trigger the formation of a new keloid, which may be similar in size or even larger. Some surgeons have greater success by injecting steroids into the wound site after the keloid is surgically removed.

What Are the Uses of Genetic Testing?

With the passage of time, it has become apparent that the entire human genetic code is now available to scientists. From this, it is now possible to test someone and predict the full range of diseases that they are likely to suffer from based on what is in their genes.

While this announcement is a welcome development, there are those who are apprehensive about this information while there are those that are elated by the prospects presented by this complete code.

To what different uses can such information be put?

The Good Side.
When you know that you have a genetic predisposition to a certain disease, it is possible for you to make a decision to take preventive measures so that you can forestall that illness from attacking you, or reduce how severely the condition can affect you once it manifests.

One of the preventive measures can be to stop habits that would quicken the onset of the disease. A habit like heavy smoking can bring on lung cancer much sooner than it would have struck had the person avoided taking to cigarettes.

Another way in which people can use this information from genetic tests is that people can prepare for that time when the disease eventually strikes. One can for instance begin making insurance payments towards their later treatment needs when they are no longer able to work due to the ravages of the disease.

The Ugly Side.
Take a look at insurance companies. How would they react if they knew that a person was very likely to suffer from a certain debilitating disease? They would certainly refuse to cover such a person, or they would make them pay through the nose (high premiums) for the policy that they want.

That is a very nasty possibility and one shudders to imagine the widespread suffering that people would go through if insurance companies demanded genetic tests before allowing you to buy a policy.

Employers too cannot be expected to respond in a different way from insurers. Many would fire or refuse to hire people that they knew were prone to serious genetic diseases. Widespread discrimination would be practiced at workplaces and laws would not be able to cope with this issue since many forms of discrimination are so subtle that it would be hard to provide evidence before a court of law.

The possibility of such negative outcomes would make people very reluctant to get tested since the drawbacks of such tests would far exceed any benefits they would get.

Final Thoughts.
Dr. Ronald A. Lohner, MD, FACS, who carries out procedures like the one depicted on this page http://lohnerplasticsurgery.com/breast-augmentation-philadelphia/ advises that it is always good to have as much information about your health as possible. That information is vital to protecting you from conditions that would affect your quality of life so instead of fearing the negative consequences that may result one can plan how to minimize those negative outcomes in a way that doesn’t deny them the benefits that possessing that information accords. Is there a better way to end this discussion?

How Do Genetics Influence Breast Cancer Risk?

If you have a family member who has had breast cancer, you are more at risk to develop the disease than someone without a family history of cancer.

DNA Abnormalities
Your genes control your cell function and growth. Errors result in faults in that function or growth. When the genes that control normal breast cells and repair cell damage have mutations or abnormalities, the risk for breast cancer is higher. These are passed from one generation to the next. The mutation does not mean that you will develop breast cancer, but your risk is higher.

Women diagnosed with breast cancer, who have abnormalities in their genes, may also have a family history of cancer of various types. However, most people who do develop breast cancer did not get it through an abnormal gene.

Likelihood of an Abnormal Breast Cancer Gene
You are more likely to have an abnormal gene if:
There has been both ovarian and breast cancer in your immediate family, especially if it was in one individual
You have mother, grandmother, aunts or sisters on either side of your family who were diagnosed with breast cancer before the age of 50
Any women in your family developed cancer in both their breasts
You have other cancers related to glands in your family – This includes colon, pancreatic or thyroid cancer.
Your heritage is Eastern European Ashkenazi Jewish
Any male in your family developed breast cancer
You are of African American descent and have had breast cancer at the age of 35 years or younger
You will not necessarily have abnormal breast cancer genes even if someone else in your family does.

American Averages
A woman who lives in the United States will have roughly a 12 to 13% chance of breast cancer sometime in life. If you have the abnormal genes, your chances of developing breast cancer may be closer to 80%. In addition, if you are a woman with the abnormal breast cancer gene, your risk is also higher for thyroid, pancreatic, colon or ovarian cancer, or melanoma.

Men who carry the abnormal gene face a higher risk of breast cancer, as compared to men who do not. They have roughly an 8% chance of breast cancer by the age of 80. This is almost 80 times higher a risk than the average man. Breast cancer in men has not been as adequately studied as the disease has been in women.

Women and Mastectomies
Even with the technological advances in modern medicine, mastectomies are still often necessary, in order to ensure that the cancer does not spread. Lymph nodes are usually removed at the same time. In some cases where cancer is suspected, a minor procedure is performed that will allow your physician to remove a small portion of your breast, for biopsy.

For women who have had mastectomies, the option is open to have breast reconstruction and breast augmentation. These are two of the procedures done by Dr. Douglas Steinbrech, M.D., F.A.C.S., who specializes in procedures like this.

The Case of Genetic Vein Disorders

Vein disorders are one of the most common hereditary disorders. There are different types and more often than not, these disorders may cause discomfort, physical limitations, and other more serious disorders.

This article will discuss two genetic vein disorders, chronic venous insufficiency and Klippel-Trenaunay Syndrome, and how these conditions affect the lives of those affected with it.

Chronic Venous Insufficiency

This disorder causes leg pain and swelling and results to development of varicose veins. CVI is caused by either damaged valves in the veins or vein blockage. When venous valves in the legs are damaged, blood cannot flow back up to the heart. As the heart is pumped back up, the valves cannot close and hold it, so the blood flows back down the veins. This process is called venous reflux. Blood then accumulates in the vein causing it to twist and enlarged. This manifests through unsightly varicose and spider veins. Venous reflux can be caused by hereditary or non-hereditary vein wall weakness; deep vein thrombosis (DVT) or blood clots; and a lack of vein valves since birth.

CVI is an extremely common condition. In fact, it can affect about 20 percent of adults in America. Further, approximately 20 to 25 million Americans are estimated to have varicose and spider veins.  

This condition may lead to other serious conditions such as hypertension, ulcers at ankles or legs, and drastic skin changes. The pain and discomfort associated with this condition limits physical activities like standing, walking, running, and exercising. Patients may be intolerable to hiking, bicycling, jogging, trekking, and long hours of walking.

Klippel-Trenaunay Syndrome

This condition hampers the normal development of blood vessels, bones, and soft tissues. The most obvious sign of the condition is the overgrowth of one limb (one arm or one leg). This affects walking and may cause severe discomfort, muscles cramps, swelling, and reduced movement.

It will also cause a port-wine stain to develop on affected limbs. This stain ranges from pale pink to deep maroon and may become lighter or darker through time. This stain is unsightly and may develop sensitive small blisters that bleed easily.

The syndrome also causes abnormal vein formation, most often varicose veins. If deep veins malfunction due to abnormal formations, it may produce DVT which can travel to the rest of the body. If it blocks veins in the lungs, this causes a life-threatening condition known as pulmonary embolism (PE).

Treatment of Venous Disorders

Those affected with CVI and Klippel-Trenaunay Syndrome should consult doctors about the best surgeries. It can be treated with basic remedies such as medicines, compression stockings, lifestyle changes, and non-surgical procedures. Non-surgical treatments such as sclerotherapy and endovenous thermal ablation are performed by most clinics like Advanced Vein and Vascular Center, a vein center in Mainline, Philadelphia. However, in more severe cases, surgical treatments such as ligation, microincision, and vein bypass are needed. Clinics also offer vein removal procedures, just like this clinic that performs vein removal in Scottsdale, Arizona.

Vein disorders can seriously stop a person from living life to the fullest, so these conditions should be addressed as soon as possible.

How to Become a Genetic Engineer

Genetics is a very important aspect of our existence. Our physical attributes and capabilities are dictated by our genes. Tall people are basically offspring of tall parents. In the same manner that athletic individuals are most often than not children of athletes or athletic parents.

If you are interested in the field of genetics, perhaps a career in Genetic Engineering for human health is one that is fit for you. Let us take a look at the roadmap you are to take if this is a career path you would pursue.

What is a genetic engineer?

A genetic engineer, especially one who focuses on human health, is one who deals with treatment of chronic diseases. They are also responsible for turning harmful bacteria into some sort of messengers that would take healing drugs to certain tissues in the body. These are just some of the basic works a genetic engineer does.

Here are three steps you should take on your education to pursue a genetic engineering career.

  1. Bachelor’s degree

Of course you should have a bachelor’s degree first. You can opt for biology or chemistry as both are branches of physical science. The best thing for you to do is consult your college adviser for guidance on this matter. Some institutions have undergraduate programs for related fields on genetic engineering; so asking for guidance from college advisers can prove to be significant.

  1. Advanced Degrees (Master’s or Ph.D.)

If you are gunning for employment beyond entry-level, then you have to take an advanced degree. A bachelor’s degree can land you an entry-level position in the genetic engineering field. But to move up the ladder, you have to upgrade yourself. Advanced degrees will provide you the exposure and experience in your researches. This is a very good preparation for what is to come in the actual field.

  1. On-the-Job Experience

Once you have completed the necessary degrees, you have to gain work experience. You’ll be glad to know that there are so many places you can go to have an OJT experience for genetic engineering. You can work as a breast cancer researcher, or as a forensic scientist.

You can even try working in this site to aid in their hormone replacement therapy in Miami.

Genetic engineering is a broad field. Check out a career in this field and you may find one that may fit you.

Can Genetic Testing Lead To Healthier Living?

Today, we are bombarded by all sorts of information about our genetic predisposition as well as about a huge array of other conditions. This begs the question, is there a qualitative change in the way people live their lives once they are armed with this information?

The answer to this may not be as straight forward as one would wish. The following discussion will explain why.

Positive Changes Made
A researcher at Boston University School of Medicine found that participants in a study that were tested for genetic predisposition to Alzheimer’s disease had some lifestyle changes so that they could reduce the likelihood that they will have the disease.

Those people exercised more, took multivitamins as well as other medications that were thought to be helpful in warding off the illness. This is despite the fact that there is no proof that such measures do indeed have an effect in staving off the disease.

Others in the tested group, particularly those who were found positive for the genome that causes Alzheimer’s, had a tendency to take on long term insurance to cater for them in the event that they develop the disease.

These are just some examples of how genetic testing for diseases long before they manifest can help individuals make lifestyle changes that result in healthier living.

But is this witnessed across the board for all conditions for which people are tested? There are findings that show that many times, genetic tests do not result in necessary changes when people receive early warnings about conditions that may afflict them with time.

Smokers “Unfazed”
In 1997 there was a study that was conducted on a group of smokers. They were tested to find out if they had a genetic predisposition to suffering from lung cancer.

Once those positive on that count were notified, there was an immediate spike in their desire to quit their smoking habit which would increase their likelihood of developing lung cancer later in life.

One year later, all that steam seems to have evaporated as there were no differences in quit levels when compared to smokers that had simply received counseling that was general.

In this regard, the genetic testing had a dismal effect when it came to nudging those at risk towards making lifestyle changes geared at safeguarding them from a condition that they were likely to suffer from if they continued smoking.

Final Thoughts.
When asked to comment on these mixed results, Dr. Andrea Basile, who carries out procedures like you see here, said that the study participants should not entirely be blamed for not acting when they should. Some of them, he went on to say, such as smokers, may be under greater influences that make it near-impossible to quit however much they wish to.

At the end of the day, the more information that people have, the more they will be equipped to make informed decisions. The few that change for the better are worth all the effort that goes into finding those testing mechanisms so that benefit shouldn’t be given up just because some people don’t change even when told of the risks they face.

Are Seasonal Allergies Genetic?

Allergies are not only annoying; they can also be life-threatening when they occur in a severe form. Allergies are an excessive immune response to substances in the environment such as pollen.

The body regards the proteins in these substances as harmful to it and it goes into overdrive in its attack against them. It isn’t uncommon to find entire families having some form of allergy and that begs the question; are seasonal allergies genetic?

While science is yet to explain why the body reacts the way to does to allergens, there have been findings to the effect that allergies are genetic.

The Gender Link
While seasonal allergies do have a genetic factor, it is not possible to pass on a specific allergy to offspring. The parents may both have allergies but their children will hardly be allergic to the same things that their parents are allergic to; they may be allergic to something else. What has become apparent is that if a parent of a certain gender has a certain allergy, chances are high that a child of the same gender will develop that allergy.

The same applies to allergies like eczema. If a mother has it, her daughter will most likely have it while there is a very minute chance that her son will get it. The same scenario plays out if the father has it.

Are There Other Factors Involved?
Research has established that many cases of allergies in families could be linked to additional factors other than heredity. Such factors include the fact those family members share the space in which they live, and their diet is basically the same for all family members.

Under such conditions, it becomes increasingly likely that if there is an allergen it will affect the family members equally and since they have a predisposition to suffer from that allergy, they may exhibit varying symptoms of allergic reaction.

It was found that if a mother ate for example peanuts while she was pregnant, her child had a quadruple chance of getting an allergic reaction to peanuts while that chance only doubled if the mother ate them while breastfeeding.

What Can Be Done About Seasonal Allergies?
Once your parents suffer from allergies, it is wise to talk to your physician since you could have allergic reactions to certain drugs due to that predisposition to suffer from allergies.

You should also discuss the situation of your kids if you both have allergies. The pediatrician will assess the situation and chart out a way to get the child onto immunotherapy or to watch out for allergic reactions to medications before they cause serious harm.

Dr. George Moynihan MD, a plastic surgeon who performs this procedure http://www.goldcoastplasticsurgery.com/rhinoplasty.aspx in Chicago, says that in some cases, nose surgery has been able to provide some relief to a number of patients that suffer from seasonal allergies.

Otherwise the first line of defense is to avoid exposure to the substance that you are allergic to during the time of the year when it is most prevalent. To avoid it, you must first know what it is that triggers that response so study your own reaction to things around you.

Do You Have Dad’s Nose? Face-Shaping Genes Identified

Do you have your mother or father’s nose? While we don’t know exactly which genes play a role in nose shape, we do know this characteristic is controlled by more than one gene. Geneticists have been doing a great deal of research over the past decade into why our noses are different shapes, and there have been some interesting conclusions.

5 Genes that Determine Face Shape
About two years ago, researchers confirmed that three genes thought to be involved in face shape (PRDM16, TP63 and PAX3) as well as two genes calle C5orf50 and COL17A1 play a role in our facial structure. Researchers were surprised, because it’s always been assumed that hundreds or thousands of genes with small effects influenced face shape. So, what do these genes do?

PAX 3 regulates muscle-cell formation and it determines the distance between the top of your nose and your eyes. People who have a mutation in PAX3 develop a condition called Waardenburg syndrome with wide-set eyes.

Mutations in PRDM16, on the other hand, causes a cleft palate in mice, as well as extensive freckling, missing teeth and thin skin.

Your Sinuses and the Shape of Your Nose
The human nose has pouches on either side called maxillary sinuses, but there is a great deal of variation in these structures. In one recent study, which you can read about by clicking here, researchers took computer tomography scans of 40 people; half African-American or native South African and half European-American. These researchers found that the greater the volume of the nasal cavity, the greater the size of the maxillary sinuses, which is associated with face size. They found that these sinuses play some role in the shape of the nose. If the face is the same size, maxillary sinuses are about 36% larger in European-Americans rather than African-Americans because Europeans usually have narrower nose shapes.

Nose Width and Climate
Scientists have also found that nose shape is determined, to some degree, by climate conditions as well. The longer the nasal passage, the more effective the nose is at warming and moistening incoming air, which is why people with ancestry from cold or dry conditions have higher, narrower noses, such as Europeans. This also explains why people with broad, low noses tend to be people from humid, tropical areas like southeast Asia and some areas of Africa.

Genetics Even Determines the Structure of Your Nose
Ask any rhinoplasty surgeon if there is a difference between the nose type of different ethnicities and you will get a resounding yes. I asked Dr. Philip J. Miller, MD, a surgeon who performs procedures like you see here, about the differences. According to Dr. Mounsey, Asians and African Americans tend to have a slightly flatter nasal structure and thicker skin in the nasal area, for example, which makes it difficult to improve the definition of the nose tip. Hispanic people tend to have thicker nasal skin as well, which sometimes requires nasal cartilage tip grafts to define the tip. These differences, which may not be apparent to the naked eye, are all determined by genetics.

Genetic Issues May Cause Pre-Disposition to Vein Problems

A lot of people associate varicose veins and other vein problems to lifestyle, weight and habit. Most common folk would say that you get varicose veins from wearing high heels, standing up for long hours, always sitting down, not walking enough or for being to heavy for your own feet. There are also old wives’ tales that say that talking a bath when tired or after a long day at work will cause a woman to have varicose veins.

While there may be a grain of truth here, science has proven that this is not totally true. According to research, genetics has a lot to do with varicose veins and other vein problems. In short, some are more prone to having it no matter how careful they may be. Metabolic and genetic problems account for a large percentage of vein problems and this means that more men and women may have vein problems which they may be unaware of.

What is Venous Thrombosis?

When blood clots form inside a vein, the resulting condition is known as venous thrombosis. The blood clot limits blood flow throughout the veins and causes inflammation as well as pain. Most of the time, the thrombosis takes place in the deep veins: the pelvis, thighs, legs and other similar areas. As mentioned earlier, sometimes a genetic problem is responsible for these issues. A condition called inherited thrombophilia makes the blood clot faster than normal. This is a genetic trait that is passed on to family members. Until now, scientists have not determined the exact factors that make the genetic problems manifest. People with this condition usually suffer from vein problems even when they are younger than 50 years old.

This means that if you have a genetic disorder, you should take measures to have your veins checked on a regular basis. You can check out online venous resource sites for more information and also search online for a vein doctor directory if you want to look for an expert near your location. It is advisable to have a check up and look for the early signs and symbols of venus thrombosis and varicose veins.

The Genetic Factor

Doctors and scientists are now looking more closely at the relationship of genetics and deep vein thrombosis. For patients with DVT but have no known medical condition that could cause it, experts are looking at the patient’s family medical history for close relatives who may have had the condition. If a loved one has had deep vein thrombosis or a pulmonary embolism, better have yourself checked immediately.

Preventing blood clots may require different procedures, and some may need surgery if the condition is pretty extreme. When this happens, it is strongly advised that the patient get the surgical procedure done. This is a serious matter that could lead to death as the veins are directly connected to your heart. Blood clots or any kind of blockage could be impeding the proper flow of blood to the rest of your body.

Do it sooner rather than later.
