Bariatric surgery is an operation that is used to facilitate weight loss. This may be achieved through one of several ways: reduced food intake due to reduced stomach capacity, reduced absorption of nutrients or both mechanisms. An example of bariatric surgery is gastric bypass surgery. There are a number of important things that New York residents should know about this procedure if you have plans of having it.
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.
Once you have qualified as a candidate for the operation, your doctor will instruct you on how you should prepare. A number of tests may have to be done as part of preoperative preparation. Restrictions may be placed on foods and drugs before and after the operation. If you are a smoker, you should stop the habit for two weeks before the operation and for the same duration afterwards.
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 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.
