Of the three types of laparoscopic weight-loss surgery gastric banding, Roux-en-Y gastric bypass, and sleeve gastrectomy banding currently accounts for about 10 percent vs. sleeve gastrectomy, 60 percent, and gastric bypass, 29 percent. At the time of the UTSW study, banding accounted for nearly half of bariatric procedures.
According to the American Society for Metabolic & Bariatric Surgery, about 150,000 to 160,000 bariatric procedures are performed annually in the U.S. That's a slight decline from a peak of 220,000 surgeries in 2009, but still up from 103,200 in 2003. The surgery, which typically costs $11,500 to $26,000, may or may not be covered by insurance.
"Over the past 10 years, the popularity of bariatric surgery has escalated. In banding surgery, it's presumed there aren't as many nutritional precautions needed as with some more invasive bariatric surgery options," said Dr. Garg.
But what the study showed is that many banding patients are prone to nutritional deficiency post-surgery, despite taking supplements and receiving nutritional counseling. Gastric banding surgery involves placing an adjustable band around the top part of the stomach to create a small stomach pouch. Because their stomach pouches are smaller, banding patients eat less and often miss important nutrients.
While there were some improvements in nutrition over the test period, the group of 23 study participants still had nutritional deficiencies of concern. At least 86 percent did not meet recommended requirements for calcium and vitamin D. In addition, many participants were slightly anemic at 12 weeks.
In order to keep their bodies healthy after bariatric surgery, Dr. Garg offered this advice:
