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.
Generally, weight loss surgeries are done as a last resort procedure for persons that are trying to lose weight but have not responded to lifestyle changes. It is recommended if one is at a high risk of suffering from weight related complications such as type 2 diabetes, gastro-esophageal reflux disease, hypertension, heart disease and stroke among others. The candidate should have a body mass index, BMI, of 40. A lower BMI of 35 is acceptable if they already have 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 types of gastric bypass that can be performed. The most common is the Roux-en-Y. This type is very popular since it can be performed through by minimal access hence there are less complications and the recovery time is markedly reduced. It involves two steps. The first is the conversion of the stomach into a small pouch through stapling or vertical banding. The capacity of the stomach is reduced and so is the food intake.
The second step is the attachment of a Y-shaped intestinal portion to the pouch. When food moves from the pouch into this part of the intestines, a significant section of the digestion tract is bypassed (hence the name). This means that there will be less absorption of nutrients and less calories will be produced. Weight loss starts to set in in subsequent weeks and 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.
