Basics Relating To Bariatric Weight Loss Surgery

By Sarah Johnson


Lifestyle changes are the most widely recommended options for weight loss in New York. The major advantage that these methods have over other options are that they are cheap and devoid of side effects. The main downside is that it takes a considerable amount of time before their beneficial effects are evident. Bariatric weight loss surgery is usually the most effective approach if one intends to lose a significant proportion of their weight in a short period of time.

Bariatric surgery is also known as a restrictive operation. This means that it limits the amount of food that the stomach can hold after a single meal. The amount of nutrients that are subsequently absorbed at the level of the intestines is reduced. Whatever is absorbed is mainly used to generate energy and very little ends up as storage in adipose tissues. Within days and weeks one begins to lose weight.

The main types of bariatric surgeries that are performed are sleeve gastrectomy and gastric banding. Although the two are fundamentally different, the end results is largely the same. They both cause a significant reduction in the functional size of the stomach which in turn reduces the amount of food eaten. One of the major differences is that banding can be reversed while sleeve gastrectomy is permanent and cannot be reversed.

To perform gastric banding, a silicon band is put on the upper portion of the stomach (fundus). By compressing this part, the stomach is reduced to a small pouch that holds just about an ounce of food. An instrument known as a laparoscope makes it possible to conduct the operation with minimal access. The use of small incisions means that the resultant scars will not be prominent.

The silicon band is connected to a long plastic tube that can be easily accessed from an area under the skin. By injecting and withdrawing saline or sterile water into the tube, the pressure that is exerted by the band can be regulated. Injecting the saline into the tube increases the pressure which effectively reduces the size of the stomach further. The reverse happens when the saline is withdrawn.

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 an operation in which surgical resection of the stomach is done to reduce its size by as much as 80%. The resultant stomach is a tubular structure that reduces the transit time of food hence reduced absorption of nutrients. The other benefit is that one experiences early satiety and consumes a lot less as a result. The side effects associated with the procedure are similar to those of banding.

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.
