Bariatric surgeries are a group of operations that are performed with the sole aim of achieving weight loss. Those that are commonly performed in New York include banding, sleeve gastrectomy and gastric bypass surgery. Weight loss is achieved through reduced food intake (as a result of early satiety), reduced absorption of nutrients or both. We will look briefly at what is involved in the bypass procedure.
Once you have made the decision to have the operation, you need to visit a general surgeon. Ensure that you have a discussion on the pros and cons of having such an operation and determine whether any other options exist. Most doctors hold the view that surgery should be done as a last resort. One needs to first attempt losing their unwanted weight by instituting lifestyle changes.
Candidates that are most likely to benefit from the surgery are those with a body mass index of 40 or more. If one is suffering from a condition that is aggravated by excess weight then a lower value may be accepted. Examples include sleep apnea, high blood pressure and diabetes among others. In these cases, surgery will help not only relieve the symptoms but will also help slow the progression.
The preparation needed for this surgery is similar to what would be required for any major operation. You need to have a number of tests that will help establish whether or not you are fit enough. Some of the tests that will be performed include a full blood count and renal function tests. You may also be asked to stop taking some drugs that are likely to impact negatively on the procedure such as aspirin and blood thinners.
One of two techniques can be used in this surgery. The Roux-en-Y is the commonest. The stomach is first reduced into a small pouch through banding or stapling before joined to the last segment of the small intestines. The first two parts are skipped (bypassed). All this is done through small incisions created in the anterior abdominal wall. One of the reasons as to why the technique us popular is because of the low rate of complications.
Weight loss due to this technique occurs due to a number of mechanisms. A reduction in the stomach size means that you will experience early satiety and a general reduction in the amount of food that is eaten. Another mechanism involved is the reduction in the surface area that is available for absorption of nutrients mainly due to the rerouting of digested food.
The second technique that is employed is known as extensive gastric bypass. It is a more radical procedure that is mainly considered in case of biliary obstruction caused by liver disease. This is why it is alternatively known as biliopancreatic diversion. To perform the operation, the lower stomach portion is removed and the upper portion is then stitched to the last section of the intestines skipping the first and the second in the process.
Reduction in the absorption of essential nutrients is a common complication. This is mostly seen when extensive bypass is performed. Another possible complication both in the short term and long term is a condition popularly referred to as dumping syndrome. The features of dumping syndrome include sweating, weakness, vomiting and nausea. These symptoms are usually experienced a few minutes after eating due to rapid food movement.
