Diabetes Improves After Obesity Surgery
Gastric Bypass Surgery May Be Realistic Option for Improvement of Diabetes Complications
Oct. 6, 2003 -- Gastric bypass surgery -- often a last resort for severely obese people -- can vastly improve diabetes, a new study shows.
The finding adds yet another benefit to this weight-loss procedure. Chest pain, shortness of breath, high blood pressure, and sleep problems also drop substantially, researchers have found.
However, the effects of gastric bypass surgery on diabetes have not received much attention, writes lead researcher Philip R. Schauer, MD, director of bariatric surgery at the University of Pittsburgh Medical Center. His report appears in the current issue of Annals of Surgery.
Even though diabetes is usually treated with medication and insulin, eventually it can progress to kidney failure, blindness, erectile dysfunction, even amputation, says Schauer.
'Very Dramatic' Diabetes Results
But his study showed the procedure can actually "cure" diabetes, Schauer tells WebMD. "Overall, after surgery these patients had complete resolution of diabetes -- very dramatic."
Jennifer Marks, MD, a diabetes specialist at the University of Miami School of Medicine, has counseled a number of gastric bypass patients. "Gastric surgery is a technique for people have tried everything else to lose weight and not been successful," Marks tells WebMD. "I recommend it as an option. It can work." She, too, has seen remarkable effects on diabetes.
However, if patients regain weight, "it also means their diabetes could come back," Suzanne Gebhart, MD, a diabetes expert with Emory University School of Medicine in Atlanta, tells WebMD.
All the 144 people in Schauer's study weighed over 300 pounds before gastric bypass surgery and were considered morbidly obese. Most were women with an average age of 40.
The surgery involves restricting the size of the stomach by stapling most of it shut, so that patients feel satisfied with small amounts of food. And some of the food isn't absorbed. These two mechanisms allow patients to lose weight.
The study's patients all had some degree or risk of type 2 diabetes, ranging from very mild to moderate to severe, he says. Some were taking no diabetes medications; others were taking several prescriptions plus insulin. Some patients had had diabetes for less than five years, some for more than 10 years.
