Gastric Bypass for Weight Loss in Miami, Florida
Gastric bypass has been performed in the United States for many years. It is the procedure that most other bariatric surgeries are compared to when discussing safety and effectiveness. In recent years, the introduction of laparoscopic procedures, often called keyhole or band aid surgeries, have made this procedure less traumatic than earlier open procedures were.
The most commonly performed gastric bypass procedure is called the Roux-en-Y gastric bypass.
How the Gastric Bypass Works
Using the Roux-en-Y gastric bypass, weight loss is achieved in two different ways. Like the gastric band procedure, gastric bypass uses a restrictive method to make the stomach smaller and restrict the amount of food a person can eat at one time.
In gastric bypass, instead of using an adjustable band, a small stomach pouch is created and disconnected from the rest of the stomach. At the same time, a new outlet is made for the small stomach pouch by attaching it further down the small intestine.
The unused part of the stomach and intestines continue to produce digestive juices which empty into the part of the intestine the food is traveling through. This provides sufficient length for food and enzymes to mix together and essential nutrients to be absorbed but does not allow the same amount of nutrient absorption as a normal digestive tract. This is why the gastric bypass is called a restrictive and malabsoptive procedure.
Weight loss with gastric bypass
Gastric bypass usually results in a faster rate and a higher total amount of weight reduction than gastric banding. However, actual results rely heavily on how well you follow the lifestyle changes necessary after bariatric surgery.
Most people that have gastric bypass experience a 50 to 60 percent reduction in excess weight in the first two years following surgery.
