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 require for the surgery resembles what happens for other major operations. A number of tests have to be conducted to establish that the candidate is ready to be operated on. Some of the most helpful tests at this point in time include hemogram (or full blood count) and renal function tests. There is also a need to stop drugs that may increase the risk of bleeding such as anticoagulants.
The surgeon can choose one of two techniques to do this operation. The first type is known as Roux-en-Y. In the technique, a small incision is first made on the abdominal wall so as to access the stomach. A portion of the stomach is stapled or compressed with a band to reduce its size. A Y-shaped intestinal section is then attached onto the stomach so that a part of the original route is bypassed (hence the name).
In the case of Roux-en-Y, weight loss will be achieved due to a number of reasons. The small size of the stomach can only allow one to eat a limited amount of food most of which is used in the provision of energy. The other effect of this operation is that the surface area available for absorption of nutrients is markedly reduced due to the bypass of a large section.
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.
There are several complications that may be encountered. The commonest is malnutrition resulting from reduced absorption of nutrients. Dumping syndrome is also fairly common and may be seen in the immediate term or after some years. It is characterized by sweating, nausea, vomiting and weakness whose onset follow the intake of food.
