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.
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 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 The reverse happens when the saline is withdrawn.
There are a number of complications that may result from this operation. Those that are encountered most commonly include nausea, vomiting, aversion to food, bleeding and infections. Some of the symptoms can be relieved by adjusting the compression exerted by the band. Once the symptoms have subsided, the pressure can be increased gradually once more to reduce the stomach to the desired 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.
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.
