Bariatric surgeries are a group of operations that are mainly performed with the aim of achieving weight loss. It is mainly performed in persons with morbid obesity. The main role of this operation is to reduce the capacity of the stomach which effectively minimizes the amount of food that one can eat a given point in time. The end result is a reduction in weight over time. There are several things on gastric bypass surgery Houston patients should know.
There are a number of requirements that have to be met for one to be considered a suitable candidate. One of them is that the potential candidate should have tried losing weight using non-surgical options such as regular exercise and having a proper diet. Persons that have conditions such as hypertension, diabetes, cerebrovascular accidents, heart disease and gastro esophageal reflux disease are potential beneficiaries.

Gastric bypass surgery if of several different types. The most popular among them is what is termed Roux-en-Y. This is mainly because of the use of small incisions. The incisions are associated with a lower rate of complications and a better cosmetic outcome compared to the other options that exist. The procedure is done in two main stages.
The first step involves the conversion of the stomach into a small pouch whose capacity is about one ounce of food. This is done by use of staples or a silicon band. The second step is the fashioning of a Y-shaped intestinal section. This segment is joined onto the pouch created from the stomach. The first and second parts of the intestines are skipped (bypassed) in this process.
Extensive gastric bypass (also referred to as biliopancreatic diversion) is a radical type that is rarely performed except as a last resort. Commonly, it is done due to severe biliary obstruction caused by liver disease. It is associated with numerous complications and a high mortality rate. The procedure involves the removal of the lower stomach section and the joining of the upper part to the intestines.
The operation is associated with a number of complications. Stretching of the pouch may occur with time and the stomach may even regain its original size in a few years. Another possible complication is that the silicone band may be eroded over time and disintegrate. Leakages of stomach acids may also occur and lead to damage of major organs.
Dumping syndrome is a complication that occurs in a significant number of people with this problem. Symptoms may include fainting, weakness, nausea, sweating and diarrhea. It usually occurs about 30 minutes after a meal (usually a sugary meal).
