Dr. Mona Khanna: We didn’t completely anticipate that gastric bypass surgery not only would give people such a psychological boost with the weight lost but it will also help some of their medical conditions although you know in retrospect of course we should have predicted it. And here are some of the conditions that can be improved or even reversed with gastric bypass surgery. The first is Type II Diabetes. Remember that’s the diabetes as associated with obesity while we found that when people are no longer obese and even by the actual procedure itself it does something to the body so that in some cases that diabetes would actually completely reversed. Sleep apnea is another condition that many obese people grab it with it and that basically is the situation where during night when you’re trying to go to sleep you have episodes of apnea which means you don’t breath. Part of the reason for that is because of the soft palate in the mouth that can tend to collapse but we found it as more prevalent in people who are obese and so by taking again that obesity away you resolve some of those symptoms in that condition. The third is high blood pressure. High Blood pressure again direct correlation with being overweight or obese. High Blood pressure can be reversed once the obesity and overweight has dropped. Now we know that heart disease is actually a directly correlated to some of this things that we’ve talked about. High Blood Pressure, Diabetes and those risk factors make your risk of developing heart disease even higher. Well if you take away those risk factors then you lower your risk of developing heart disease. Another thing directly related to heart disease as well is cholesterol when you have high cholesterol especially the bad cholesterol which is the LDL cholesterol and you have gastric bypass surgery we tend to see people drop their cholesterol levels, very, very positive sign when you drop that bad cholesterol level and again it lowers your risk of developing heart disease. We find that people of head gesture bypass surgery also if they have had asthma exacerbations in the past where they just have an asthma attack they tend to develop attacks less frequently. So all of these benefits of gastric bypass surgery we’re seeing now with patients who are out for longer and longer periods of time after the surgery since it’s become common barely recently. We talked a lot about the benefits of gastric bypass surgery which is great but you should never ever go into a major operation especially in major abdominal operation like gastric bypass surgery without being fully informed of the risk. There are certainly are some draw box and let’s break them up into two categories but first is during the actual operation and in the pre operation area and just a few days out of the operation and the second category will be kind of life long challenges and the first one of course, the first category brings us to the most common complication of any set of operation and that’s bleeding. You can of course have excess bleeding that will need to be taken care off, the bleeding area will need to be stopped and you’ll be administered you know external blood that’s the first. The second is you can developed collapsed lungs again with any type of major surgery this is a possible complication you can develop other complications such as what we call pulmonary embolism and that is where a blood clot develops and that blood clotting go anywhere most commonly it can go to your lungs and that can affect whether or not your liver die. The next is infection and again complication of any surgery anytime you have any kind of loss of integrity of the skin or other organs where in this case you’re basically cutting the skin open you can have bacteria, viruses, other microbes, funguses, you can have them affect the body and develop and infection that way. So those are some of the draw box in the operational and the preoperational period. Now that second category
