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.
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.
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).
Weight loss due to this technique occurs due to a number of mechanisms. A reduction in the stomach size means that you will experience early satiety and a general reduction in the amount of food that is eaten. Another mechanism involved is the reduction in the surface area that is available for absorption of nutrients mainly due to the rerouting of digested food.
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.
