"The number of annual [bariatric] surgeries now is closer to 200,000 or 250,000.

"The National Institutes of Health recommends bariatric surgery for people with a B.M.I. over 40 (or 35 to 40 if they also have related medical condition, like diabetes). A Food and Drug Administration panel recently recommended that the B.M.I. base for lap-band surgery (a form of adjustable-band surgery) be lowered to 35 and higher (30 to 35 if they have a related disease).

"Adjustable gastric banding is the second most popular form of bariatric surgery. The most common is laparoscopic gastric bypass, which decreases the size of the patient’s stomach and also the body’s ability to fully absorb food and thereby calories. Gastric bypass is more expensive but typically results in greater weight loss than gastric banding.

"But about 25 percent of gastric banding patients have not lost weight two years after surgery, Dr. Blackstone said. That’s in part because those patients fail to revamp their diet and exercise patterns.

Note: adjustable gastric band

(A laparoscopic adjustable gastric band, commonly referred to as a lap band; As the upper part of the stomach registers as full, the message to the brain is that the entire stomach is full)

Quote:

"As patients lose weight, their bands will need adjustments, or “fills,” to ensure comfort and effectiveness. The gastric band is adjusted by introducing a saline solution into a small access port placed just under the skin. * * * When the band is inflated with saline solution, it places pressure around the outside of the stomach. This decreases the size of the passage between the pouch created from the upper part of the stomach and the lower stomach and further restricts the movement of food.


The lap is short for laparoscopic.
