Lifestyle changes are one of the most effective approaches in achieving weight loss. While their effect can be clearly appreciated in a majority of New York residents over time, there is a smaller group of people in whom these lifestyle changes alone cannot achieve the desired results. These people form the bulk of potential candidates for surgical weight loss procedures which include gastric banding and sleeve gastrectomy. The two operations are examples of bariatric surgery.
Bariatric operations are also termed restrictive operations. The reason as to why this is the case is due to their effect in reducing the stomach capacity. The amount of food that is eaten in one sitting is markedly reduced. There is early satiety and reduced food consumption. The reduced intake of food causes weight loss in subsequent weeks and months.
Gastric banding involves the placement of a silicon band on the fundus (upper part) of the stomach. The band exerts a squeeze in this region effectively converting the organ into a small pouch with an outlet capable of holding just an ounce of food. This procedure is done using laparoscopy which has a number of advantages over conventional (open) surgical operations. They include, smaller incisions, less bleeding and less prominent scars.
The band is connected through a plastic tubing to an area just below the skin. The surgeon (or patient) can exert control on the pressure created by the band. When saline is injected through the tube, the pressure is increased which decreases the volume of the stomach further. This may be needed if the desired effects are not being seen. Drawing the saline achieves the reverse effect which is a reduction in the squeeze and an increase in the stomach volume.
Gastric banding has been shown to cause up to 50% in weight loss in a couple of months. The procedure is largely safe but a few side effects may be experienced. Such may include nausea and vomiting, wound infections or minor bleeding. Adjusting the tube often resolves the nausea and vomiting but removal of the tube may be needed if these effects are severe.
Sleeve gastrectomy (or gastric sleeve) refers to the surgical removal of a part of the stomach. This may be as much as 80%. The remaining stomach is a tubular pouch which closely resembles a banana. This method helps reduce weight in two ways: reduced capacity of the stomach and faster movement of food (hence less absorption). The shape is also believed to influence gastric hormone production such that one feels less hungry.
Sleeve gastrectomy has been approved for use in children and adolescents. Studies show that it has no negative effects on the growth of children. Possible complications of this procedure include leakage of food, nausea, aversion to food, infections and esophageal spasms. Over time, the stomach may dilate but not significantly. It is important to remember that unlike the banding procedure, the sleeve procedure is irreversible.
These two surgeries are performed as day cases. One can, therefore, be released to go home on the same day. Resumption of the normal daily routine can occur within a day or two. As for the diet, one needs to be on liquid diet and mashed foods for at least two weeks. The food to be eaten for the first two weeks should be either liquid diet or mashed foods.
