Bariatric surgery is any surgical operation that is conducted with the aim of reducing body weight. The main types that are performed commonly in New York include gastric bypass surgery, gastric banding and sleeve gastrectomy. Although a few differences exist among these surgeries, they are fundamentally the same in the manner in which they achieve their desired effect. In this article we explore the procedure involved in the bypass operation as well as the associated risks and benefits.
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 who wishes to have this operation should ideally have a body mass index of at least 40 which puts them in the category of morbid obesity. In the event that they also have a weight related medical condition such as diabetes, hypertension or sleep apnea, they will be considered for the operation even with a lower index. Surgery helps slow down the severity of symptoms associated with these conditions.
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 alternative is what is termed extensive gastric bypass. This is a more radical approach that is mainly used in the event of biliary obstruction resulting from liver disease. It is for this reason that the procedure is sometimes called biliopancreatic diversion. The surgery itself involves the removal of the lower stomach portion and joining the upper portion to the lower part of the small intestines.
Even as you plan to have the bypass, there are a number of potential risks that you should be aware of. Reduced absorption of useful nutrients is the most commonly encountered. It is especially severe in the case of extensive gastric bypass. Dumping syndrome is a collection of symptoms associated with rapid movement of food through the gut once the procedure has been performed. They include diarrhea, nausea, vomiting, sweating and weakness among others.
