The demand for weight loss surgery has been increasing in New York thanks to the numerous advances in surgical techniques that have not only made this option safe but quite effective as well. Lap-band and laparoscopic sleeve gastrectomy are also known as bariatric surgeries. While the may be used in virtually anyone, it is important to stress that they are most suitable for persons that have tried the lifestyle options of losing weight but have been unsuccessful.
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.
The lap band procedure is usually done using an instrument called a laparoscope. The exact procedure involves minimal access of the abdomen using three small incisions. A silicon band is usually placed on the upper region of the stomach where it causes compression. With the organ now converted into a small pouch, only a small amount of food can be held at any one time.
There are a number of side effects associated with this surgery. They include bleeding (usually minimal), vomiting, nausea and aversion to food. The compression force from the band can be increased or reduced to minimize the symptoms. This is can be achieved by injecting or withdrawing water from a plastic tubing attached to the band. When water is injected the compression increases and when it is withdrawn, it reduces.
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.
There are some situations in which these operations are deemed unsafe. In case one has hormonal imbalance (as is the case of hypothyroidism), the surgery is usually postponed until the condition has been treated. Other high risk situations include the presence of gastrointestinal diseases such as peptic ulcers, esophagitis and inflammatory bowel disease 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).
