Weight loss operations are also known as bariatric operations. They work by limiting the amount of food one can consume hence are also referred to as restrictive surgeries. The main types that are offered in New York include sleeve gastrectomy, gastric bypass surgery and gastric banding. While there are some differences in the way in which each of them is done the end result is more or less the same. In this article we look at the important aspects of the bypass surgery.
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.
The candidate undergoing gastric bypass should ideally have a body mass index (BMI) of at least 40. If the BMI value is less than this then the benefits may not be that much. For persons that have weight related complications such as high blood pressure, diabetes and sleep apnea, the BMI cut-off value has been set at 35.
The steps that are involved in preparing for this operation are more or less the same as those involved in other surgeries. One needs to be subjected to a number of tests to determine whether they are fit enough to have the surgery. Some of the important tests conducted routinely include renal function tests and a full blood count. Some drugs such as aspirin and anticoagulants increase the risk of bleeding and should be stopped before the operation.
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.
