Bariatric surgeries are a group of surgical procedures whose objective is to assist in weight loss. This is achieved through a reduction of food consumed (reduced stomach volume), a reduction of nutrient absorption or both. Gastric bypass surgery is one of these operations. There are a number of things New York residents need to know if they are considering having this operation.
Weight-loss surgeries should only be considered after other conservative measures such as lifestyle changes have proved to be ineffective. They are suitable for persons that are at a high risk of developing weight related complications such as high blood pressure, type 2 diabetes, heart disease, stroke and gastro-esophageal reflux disease among others. The candidate should have a body mass index of 40 or more unless they already have complications where the cutoff is lowered to 35.
If you meet the required criteria, the operation will be scheduled to take place when you have been adequately prepared. You may need to have a number of tests to ascertain that you are ready for the operation. You may be asked to scale down or withhold on some drugs and foods until the operation is over. Smoking affects wound healing and should be stopped at least two weeks in advance.
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 next step is to attach a Y-shaped section created from the small intestine onto the pouch. This is what is referred to as the bypass (food skips part of the digestive tract). Subsequently, one can only absorb a limited amount of nutrients. There are very few calories that are left as excess to be converted into fat deposits. Over time, weight gain is tamed.
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 collection of symptoms that may be experienced by persons that have undergone the bypass procedure. Within 10 to 30 minutes of eating, there is a sudden onset of nausea, weakness, abdominal discomfort and at times, fainting. This syndrome is likely to be encountered when one eats sugary foods or sweets and is caused by the rapid movement of eaten foods through the stomach into the small intestines.
