Bariatric operations are types of surgeries that help in weight loss. The idea is to reduce the food that can be held by the stomach at a given point in time (which reduces food intake) or to reduce the absorption of both. Some modalities achieve their results through both mechanisms. Gastric bypass surgery is one of the commonly performed weight loss operations in New York.
In general, weight-loss surgeries should be performed as a last resort for people who have tried all the non-surgical options of weight loss but have been unsuccessful. They are likely to be more beneficial in persons who are suffering from or are at risk of developing weight-related complications such as heart disease, hypertension, diabetes type 2, gastro-esophageal reflux disease and stroke among others. The general recommendation is that the candidate should have a BMI(body mass index) of not less than 40 (or 35 if they already have the complications).
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 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.
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.
