Bariatric surgery is an operation that is used to facilitate weight loss. This may be achieved through one of several ways: reduced food intake due to reduced stomach capacity, reduced absorption of nutrients or both mechanisms. An example of bariatric surgery is gastric bypass surgery. There are a number of important things that New York residents should know about this procedure if you have plans of having it.
In general, weight-loss surgeries should be performed as a last resort for people who have tried all the non-surgical options of weight loss but have been unsuccessful. They are likely to be more beneficial in persons who are suffering from or are at risk of developing weight-related complications such as heart disease, hypertension, diabetes type 2, gastro-esophageal reflux disease and stroke among others. The general recommendation is that the candidate should have a BMI(body mass index) of not less than 40 (or 35 if they already have the complications).
Once you have qualified as a candidate for the operation, your doctor will instruct you on how you should prepare. A number of tests may have to be done as part of preoperative preparation. Restrictions may be placed on foods and drugs before and after the operation. If you are a smoker, you should stop the habit for two weeks before the operation and for the same duration afterwards.
There are different forms of gastric bypass surgeries that exist. The most commonly performed is the Roux-en-Y. The reason as to why this type is very popular is the fact that it can be easily done through small incisions. This helps to reduce the rate of complications and to shorten the recovery time. It is performed in two major steps. The first step is the creation of a pouch from the stomach by use of staples or a silicon band.
The second step is the fashioning of a Y-shaped portion of the intestines and attaching it onto the pouch. This means that the food can move directly from the pouch (stomach) into the Y-shaped portion and bypass another part (hence the term). The result of this is a reduction in the absorption of nutrients and calories. The rate of weight gain is markedly reduced within weeks to months.
Another type of operation that may be done albeit rarely is extensive gastric bypass (also termed biliopancreatic diversion. It is an operation that is quite complicated than the conventional procedure. It entails the anastomosis (joining) of the first part of the stomach to the last intestinal section and getting rid of the lower stomach. The other two intestinal parts are bypassed.
There are a number of risks that are associated with these operations. One of them is the fact that the pouch may stretch causing the size stomach to increase in size. In some cases, it has even regained its original size. The band may get eroded and disintegrate with time. There have been incidences where leakage of stomach acids have caused damaged to other organs.
Dumping syndrome is a condition that results from the rapid movement of food through the stomach. Whenever this happens, affected persons may experience a number of symptoms that include weakness, nausea, fainting, sweating and diarrhea. The symptoms are most likely to occur when one eats sugary foods (usually after 10 and 30 minutes after eating). Some people have also have late symptoms that occur about three hours after eating.
