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.
As soon as you have been booked for the operation, you will be instructed on what you need to do as part of the preparation. You may be subjected to some tests to establish if you can withstand the operation. You may be asked to withhold on some drugs or foods to reduce the risk of complications. If you smoke, you should stop 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 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.
A rare type of operation that may be performed is extensive gastric bypass. This is also known as biliopancreatic diversion. It is more complicated and takes a lot longer than the conventional bypass procedure. In the operation the lower part of the stomach is removed and the remainder is connected to the last intestinal part leaving out the first two parts. Due to the associated severe nutrient deficiency, it is not done routinely.
You need to be aware of the attendant risks of these surgeries. A major risk is the fact that the pouch mat dilate over some months or years effectively increasing the stomach size. It is possible for it to even revert to its original size. The band and the staples may disintegrate and fall off which reverses the procedure. There are cases where stomach acids leak through the incisions and enter the abdominal cavity causing damage to internal 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.
