Having a balanced diet and engaging in physical activity regularly are two of the most well-known options of weight loss. While they may be effective in a majority of New York residents, there are cases where a more aggressive approach is needed. Surgical options such as gastric banding and sleeve gastrectomy are often considered as a last resort for such cases. They are types of what is referred to as bariatric surgery.
The two types of procedures are restrictive surgeries. This means that they reduce the size of the stomach which effectively reduces the amount of food that it can hold. Persons who have had the procedures begin to have early satiety which reduces their food intake. Over time, they begin to lose weight since most of the food that is eaten is used to provide energy and very little, if any, is stored as fat.
Gastric banding is achieved by use of a silicon band using laparascopic approach. When the band is slipped onto the upper part of the stomach (the fundus), it squeezes it to leave just a small outlet. The estimated capacity of this pouch is one ounce of food. Laparascopic procedures, use small entry points (ports) that result in smaller scars later on. This is in contrast to open surgeries in which large incisions have to be made.
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 involves the removal of a large part of the stomach to leave between 20 and 25% of the original. The resultant shape is tubular or sleeve-shaped (hence the name). Weight loss is mainly due to two effects. The first is the reduced volume which also reduces food intake and contributes to early satiety. The second is the increased transit time that reduces food absorption.
Sleeve gastrectomy may be used in adolescents and children. Studies have ruled out any major effects on growth in children less than 14 years. The side effects that one should anticipate include nausea, aversion to food, leakage of food, infections and esophageal spasms among others. After some years, the stomach may dilate slightly but this is hardly a cause for worry.
The two bariatric operations are usually done as day cases. You can home on the same day that you are operated. One can resume their daily routine within 24 to 48 hours. The general advice is that one remains on light diet consisting of mashed up foods and liquids for at least two weeks. Soft foods and the regular diet follow thereafter.
