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.
It is important that the client and the surgeon have a detailed discussion on the need for the operation first before a decision is made. Other options of losing weight should be offered and tried out with surgery coming in as a last resort. Lifestyle changes are among the most effective and are also affordable by a majority of the population.
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.
There are two main techniques that are employed in performing this operation. The commoner of the two is known as Roux-en-Y. It is a technique that permits the performance of the surgery through a small opening which reduces the rate of complications and improves the recovery time. The stomach is first reduced in size through stapling or banding and then joined to Y-shaped part of intestines. The first and second intestinal portions are usually bypassed.
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.
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.
