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.
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.
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 several types of gastric bypass operations that exist. The most common is known as the Roux-en-Y. It can be performed through a small incision which helps to reduce the time needed for recovery. The first step in this operation is to staple the stomach together or to place a band in the vertical plane which converts the organ into a small pouch. This reduces the amount of food that can be held at any given point in time.
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.
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 refers to a number of symptoms that are experienced in some patients that have undergone these procedures. It is characterized by nausea, sweating, fainting, weakness and diarrhea. These symptoms occur after ten to thirty minutes following the consumption of food. They are most likely to be experienced when one eats sugary foods or sweets. The underlying cause is the rapid movement of food through the stomach.
