Lifestyle happens to be the reason why we attack these patients with therapy, surgical or medical, unlike the venous disorders, which life is at risk. And superficial vein disease is usually a matter of lifestyle and not life-threatening. And so that happens to be the most important reason why we do these patients, how to prevent this from happening. Once again, compression stockings, weight control, and some level of exercise are priceless in the prevention of these problems from happening. Nothing you can do about your number of pregnancies you have had, or a contraception that you decided to have. Those are also risk factors. But as we discussed before, the more pregnancies a woman has had the more the risk, the more years that that patient has tried oral contraceptives as a method of contraception, the more risk they have, but in stuff that you can avoid is increase your level of exercise and weight control as far as being active and using stockings. Those are the main areas that we can focus on prevention.
