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 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.
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.
