Is Your Weight Affecting Your Veins?

It’s really no secret that obesity has the potential to cause a great deal of health issues, so you probably don’t need me to tell you that losing weight will positively impact your body. However, while having an awareness that obesity may potentially lead to physical complications is one thing, really understanding the strain it puts on your cardiovascular system is another.

Your circulatory (or cardiovascular) system is comprised of a connected web of arteries, veins and capillaries that circulate blood throughout the body, along with an assortment of nutrients such as oxygen, amino acids, electrolytes and carbon dioxide. When the system works as it should, it plays an integral role in helping the body fight disease and generally maintain the “status quo.”


Conversely, when obesity is a factor, the body is saddled with additional tissue that the cardiovascular system has to work extra hard to supply.  While this not only intensifies the amount of strain placed upon the heart (since its output must increase), the veins often struggle to deal with the resulting rise in blood pressure. When this happens, the veins must work harder to carry blood back toward the heart against a higher-pressure system created by increased body mass in your abdomen, pelvis and chest.  This increased venous pressure causes the valves within the veins (whose job it is to prevent blood from pooling in the legs) to weaken and not close properly.  The valves become “leaky”, remaining partially or completely open, allowing blood to flow backwards in the veins. This is called “venous insufficiency” because the veins are not working sufficiently.

The result is pooling blood that, instead of being transported to the heart, stagnates in the legs. When this happens, blood engorges the veins in the legs, including those directly under the skin, causing them to bulge out of the skin. In addition, the legs can become swollen and patients may also experience symptoms such as leg pain, heaviness or tiredness of the legs, skin discoloration, and in some cases, ulcers.


While obesity clearly remains a risk factor in the emergence of venous disease, it is not the only factor.  Plain and simple, not all overweight individuals will develop it, just as not all smokers will develop lung cancer. Things like heredity and family history have the potential to play a large role; however, prevention is important and, while you can’t control your genetics, you can certainly regulate what you put in your body and how much exercise you get.

At the end of the day, once the valves in your veins have become damaged, simply losing weight will not fix or erase the problem. Yes, it may go a long way towards relieving some of the pressure and increasing your mobility, but it will not stop the veins from leaking once they’ve stopped working correctly.


Therefore, what you should take from this is:

  1. Understand the importance of prevention. Your body requires consistent care to function properly, so making a point to exercise and keep tabs on your eating habits will go a long way towards saving you a lot of time, effort, money and pain.
  2. Regardless of the cause, once it starts, venous insufficiency will not simply go away on its own. Again, lifestyle changes may help reduce the severity of your symptoms, but will not eradicate the issue. The only way to do this is to work with an experienced vascular surgeon who can develop an individualized treatment plan to meet your needs.
  3. If weight loss is your ultimate goal—yet exercise is extremely difficult due to your condition—treating your veins can relieve leg pain, swelling and fatigue, thereby allowing you to embark upon a healthier, more active life.
