Bariatric operations are types of surgeries that help in weight loss. The idea is to reduce the food that can be held by the stomach at a given point in time (which reduces food intake) or to reduce the absorption of both. Some modalities achieve their results through both mechanisms. Gastric bypass surgery is one of the commonly performed weight loss operations in New York.
Generally, weight loss surgeries are done as a last resort procedure for persons that are trying to lose weight but have not responded to lifestyle changes. It is recommended if one is at a high risk of suffering from weight related complications such as type 2 diabetes, gastro-esophageal reflux disease, hypertension, heart disease and stroke among others. The candidate should have a body mass index, BMI, of 40. A lower BMI of 35 is acceptable if they already have complications.
As soon as you have been booked for the operation, you will be instructed on what you need to do as part of the preparation. You may be subjected to some tests to establish if you can withstand the operation. You may be asked to withhold on some drugs or foods to reduce the risk of complications. If you smoke, you should stop at least two weeks in advance.
There are different types of gastric bypass that can be performed. The most common is the Roux-en-Y. This type is very popular since it can be performed through by minimal access hence there are less complications and the recovery time is markedly reduced. It involves two steps. The first is the conversion of the stomach into a small pouch through stapling or vertical banding. The capacity of the stomach is reduced and so is the food intake.
The second step is the attachment of a Y-shaped intestinal portion to the pouch. When food moves from the pouch into this part of the intestines, a significant section of the digestion tract is bypassed (hence the name). This means that there will be less absorption of nutrients and less calories will be produced. Weight loss starts to set in in subsequent weeks and months.
Another type of operation that may be done albeit rarely is extensive gastric bypass (also termed biliopancreatic diversion. It is an operation that is quite complicated than the conventional procedure. It entails the anastomosis (joining) of the first part of the stomach to the last intestinal section and getting rid of the lower stomach. The other two intestinal parts are bypassed.
One needs to be familiar with the possible risks of these operations. One of the risks is the fact that the pouch can dilate over time and increase in size. The dilatation may even cause it to revert to its original size. The band may be eroded causing it to disintegrate together with the staples. This effectively reverses the procedure. In rare circumstances, stomach acids can leak and cause injury to internal organs.
Dumping syndrome is a condition that results from the rapid movement of food through the stomach. Whenever this happens, affected persons may experience a number of symptoms that include weakness, nausea, fainting, sweating and diarrhea. The symptoms are most likely to occur when one eats sugary foods (usually after 10 and 30 minutes after eating). Some people have also have late symptoms that occur about three hours after eating.
