What You Should Know About Bariatric Weight Loss Surgery

By Sarah Johnson


A number of methods can be used to achieve weight loss. The most widely used options in New York involve the making of lifestyle changes including the adoption of healthier diets and engagement in regular physical exercise. These methods are safe and effective for a majority of people. Their main undoing is the fact that they take too long to work and may not be appropriate if one needs to shade off a significant proportion of their weight rapidly. Bariatric weight loss surgery is often the option in such cases.

Bariatric operations are also called restrictive surgeries. This term is sometimes used because of the reduction in stomach capacity that is created by the surgeries. The amount of food that can be held by the stomach in any one sitting is considerably reduced and this translates to reduced absorption of nutrients. The few calories obtained from the food are mainly used for the provision of energy with very little going to storage as fat.

The main types of bariatric surgeries that are performed are sleeve gastrectomy and gastric banding. Although the two are fundamentally different, the end results is largely the same. They both cause a significant reduction in the functional size of the stomach which in turn reduces the amount of food eaten. One of the major differences is that banding can be reversed while sleeve gastrectomy is permanent and cannot be reversed.

To perform gastric banding, a silicon band is put on the upper portion of the stomach (fundus). By compressing this part, the stomach is reduced to a small pouch that holds just about an ounce of food. An instrument known as a laparoscope makes it possible to conduct the operation with minimal access. The use of small incisions means that the resultant scars will not be prominent.

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 When the saline is injected the size reduces, and when it is withdrawn the compression reduces and the stomach size increases.

This surgery is fairly safe but one should be aware of possible risks that exist. Nausea, vomiting, infections and aversion to food are among the most commonly encountered. Releasing the compression slightly by drawing a bit of saline from the tube helps relieve a number of these symptoms. The compression can then be restored slowly over tome to achieve the original stomach size.

Sleeve gastrectomy is a surgical operation involving resection of the stomach along its length. Between 75 and 80% is removed converting the organ into a tubular structure. Early satiety and reduced transit time in the stomach reduced the overall amount of nutrients absorbed. Side effects associated with this surgery are similar to those seen with the banding procedure.

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.
