Important Facts On Bariatric Weight Loss Surgery

By Sarah Johnson


Lifestyle changes are the most widely recommended options for weight loss in New York. The major advantage that these methods have over other options are that they are cheap and devoid of side effects. The main downside is that it takes a considerable amount of time before their beneficial effects are evident. Bariatric weight loss surgery is usually the most effective approach if one intends to lose a significant proportion of their weight in a short period of time.

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.

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 performed by placing a silicon based band on the stomach upper portion (also known as fundus). This is achieved through minimal surgical access using an instrument known as a laparoscope. The incisions made are quite small hence there is rarely any need to worry about excessive bleeding or unsightly scars later on. The lower stomach portion forms a small pouch whose capacity is about an ounce of food.

The band is usually continuous with a plastic tubing accessible from an area under the skin. The role of this tube is to help adjust the stomach size from time to time whenever the need arises. Injection of sterile water into the tubing increases the pressure on the stomach which in turn reduces the capacity even further. Drawing the water, on the other hand, releases the pressure and increases the capacity as a result.

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.
