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 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 two main forms of bariatric operations are gastric banding and sleeve gastrectomy. Although the two are slightly different in the manner in which they are performed, the results are more or less the same. The main difference is that banding is a reversible procedure while gastrectomy is not. The major similarity is that both reduce the size of the stomach.

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.

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.
