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.
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 silicon band is connected to a long plastic tube that can be easily accessed from an area under the skin. By injecting and withdrawing saline or sterile water into the tube, the pressure that is exerted by the band can be regulated. Injecting the saline into the tube increases the pressure which effectively reduces the size of the stomach further. The reverse happens when the saline is withdrawn.
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.
Recovery from the operations typically takes a few weeks. A liquid diet is recommended for about two weeks after which you can resume your normal diet. Results vary from one patient to another depending on a number of factors that include the initial weight, surgical skills of your doctor, technique employed and so on. Combining the surgery with lifestyle options achieves even better results.
