For individuals who constantly struggle with excessive weight and cannot lose it through traditional methods of diet and exercise, bariatric surgery may be a good option for promoting significant weight loss. Bariatric surgery can also improve or even cure obesity-related conditions such as type 2 diabetes, high blood pressure, cardiac disease, sleep apnea, and joint pain.
Bariatric surgery, also called weight loss surgery, is growing in popularity, with nearly 150,000 performed each year in the U.S.
Weight loss surgery helps a patient lose weight by restricting food intake or changing the way digestive processes work. Restrictive procedures - These weight loss surgeries limit the amount of food a patient can eat at any one time. This is achieved by using a flexible band to create a small pouch at the top of the stomach. When a restrictive surgery patient eats, the pouch can only hold three to four ounces of food before signaling a feeling of fullness. Therefore, patients eat much less while still feeling full.
The most commonly performed restrictive procedure is the LAP-BAND Malabsorptive procedures - These surgeries limit the body's ability to absorb calories by rerouting food to travel around a large part of the stomach and a small part of the small intestine. A patient's "new" digestive system after surgery has a shorter small intestine and a change in where the stomach connects to the small intestine.
The greatest number of bariatric surgeries performed right now are Roux-en-Y gastric bypass surgeries. Gastric bypass surgery is a malabsorptive procedure that also uses a restrictive element. A small stomach pouch is created, and the digestive system is altered to "skip" some of the small intestine, as well.
The average weight loss seen in gastric bypass patients is 60 percent of their excess weight, or an estimated 140 pounds.
If you have questions about weight loss surgery options and you live in the Los Angeles, California area, please contact one of the nation's most highly respected bariatric surgeons, Dr. Carson Liu. You can also read a story about two of Dr. Liu's successful weight loss patients, as featured on ABC's Good Morning America.
