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 surgical operations are also known as restrictive operations. This is because they generally work by limiting the amount of food that the stomach can hold at any given point in time. Less nutrients are delivered to the body tissues. Most of these nutrients are used in the provision of energy with very few calories ending up as stored fat. The end result is rapid loss of weight.
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.
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.
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.
