Basics Relating To Bariatric Weight Loss Surgery

By Sarah Johnson


There are numerous methods that can be used in losing weight by New York residents. The most widely used are dietary changes and engagement in physical exercise. While these are effective and safe in most people, they tend to take quite long. They may not be appropriate for a person that intends to shed off extra pounds for a special occasion within a short period of time. Bariatric weight loss surgery is an option in this case.

Bariatric surgery is also known as a restrictive operation. This means that it limits the amount of food that the stomach can hold after a single meal. The amount of nutrients that are subsequently absorbed at the level of the intestines is reduced. Whatever is absorbed is mainly used to generate energy and very little ends up as storage in adipose tissues. Within days and weeks one begins to lose weight.

Gastric banding and sleeve gastrectomy are the main forms of bariatric operations offered in most centers. There is a difference in the manner in which each of them is performed but the effect is largely the same (both result in a significant reduction in the stomach volume). The main difference between them is that gastric banding can be reversed while sleeve gastrectomy cannot.

Gastric banding is usually performed using a laparoscope. It involves the placement of a band (silicon-based) to the upper stomach region so as to cause compression. The lower portion is converted into a small pouch that can hold an ounce of food or less. Laparoscopy makes it possible to conduct the operation through small incisions which leads to fewer complications and less prominent scars.

A long plastic tube connects the band to an accessible area under the skin. The role of the tube is to help regulate the compression exerted on the stomach by the tube which effectively increases or reduces its size. This is achieved by injecting or withdrawing a small amount of water (or saline) from the tube. When the saline is injected the size reduces, and when it is withdrawn the compression reduces and the stomach size increases.

One may suffer from a number of side effects after undergoing this surgery. They include nausea, vomiting, aversion to food, minor bleeding and infections. One of the interventions that can be used to reduce the incidence of nausea and vomiting is through reducing the compression by the band so that the stomach size is slightly increased. Readjustments can then be done slowly until the desired size is attained.

Sleeve gastrectomy involves surgical resection of the stomach with the aim of reducing its size. After the operation only 20 to 25% is left. The structure that is left is more tubular which reduces the transit time of food. Reduced absorption of nutrients, therefore, occurs due to two main reasons: the increased transit time and the reduced intake of food. Side effects here are similar to those of banding.

Recovering from the operation takes just a few weeks. One can resume their regular diet after about two weeks. The results vary from one person to another due to a number of factors. These include the surgical technique used, the magnitude of the problem, complications and so on. To increase the chances of success, you will be well advised to adopt a change in lifestyle as well.
