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 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 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.
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.
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.
