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 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.
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 type is called extensive gastric bypass. As the name suggest, this technique is quite radical. In this technique, the lower part of the stomach is cut and discarded and the remaining upper part joined to the last segment of intestines which means that a large segment is bypassed. Since it is mostly considered when there is biliary obstruction, it is also known as biliopancreatic diversion surgery.
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.
