There is an exponential rise in the demand for weight loss surgical operations in New York . The major contributing factor for this surge is the safety and the effectiveness of modern surgical techniques. The two most common types of bariatric surgery are lap-band and laparoscopic sleeve gastrectomy. Although these operations can be offered to anyone, the general advice is that one should first try losing weight using lifestyle changes.
These two surgeries are slightly different in the way in which they are done but their effect is the same; they all reduce the size of the stomach. As a result the amount of food that can be eaten during a single meal is markedly reduced. Most of what is consumed is used for energy provision and very little ends up as stored fat. Over time, there is net weight loss. The main difference that exists is that lap band is temporary (reversible) while gastrectomy is permanent.
Lap band surgery is usually conducted using a laparoscope. This is an instrument that makes it possible to enter the abdomen through minimal access. A silicon based band is placed on the upper section of the stomach such that it compresses the area and reduces the organ to a small pouch. Approximately one ounce of food can be held by the pouch after a single meal.
After the operation, one may suffer from a number of side effects that include minimal bleeding, aversion to food, nausea and vomiting. Reducing the compression force by the silicon band may help reduce the severity of some of the symptoms. This is made possible by injecting or drawing saline from a tube that is connected to the band. When water is injected into the tube the size reduces and when it is withdrawn it increases and symptoms abate.
Sleeve gastrectomy reduces the size of the stomach to between 20 and 25% of the original. The shape becomes tubular and closely resembles a sleeve. With a reduction in the capacity, the amount of food that one can eat also reduces markedly. In addition, there is a reduction in the transit time of food within the gut hence less absorption of nutrients.
The ideal body mass index, BMI, of a potential candidate should be more than 40. For persons that are already suffering from conditions believed to be caused or aggravated by excessive weight, a lower BMI is usually considered. Examples of these conditions include sleep apnea, esophageal reflux disease, hypertension and diabetes among others. Research has shown that surgery helps reduce the severity of these conditions.
A number of high risk situations in which having the procedure is not recommended include. One of them is the presence of a hormonal abnormality such as that involving the thyroid hormone. The surgery has to be postponed in this case until the problem is treated. Other likely high risk conditions include esophagitis, inflammatory bowel disease and peptic ulcers among others.
Typically, the surgery is done as a day case which means that one can be released from the hospital on the same day. In a few cases, one may be kept on the hospital for between 24 and 48 hours for observation. A liquid dies is recommended for the first two weeks after the operation so as to allow for proper healing of the stitched regions on the stomach (in the case of gastrectomy).
