According to an article in the LA Times, "As many as 86% of obese people with Type 2 diabetes find their diabetes is gone or much easier to control within days of having weight-loss surgery, according to a meta-analysis of 19 studies published earlier this year in the American Journal of Medicine (78% of patients with a remission of diabetes and 86.6% with remission or improvement). But experts still aren't sure why obesity surgery helps resolve Type 2 diabetes or how long the effect might last. And they disagree on how big a role surgery should take in treating the illness."
HAVE GASTRIC BYPASS WEIGHT LOSS SURGERY LOSE YOUR TYPE 2 DIABETES COULD IT BE THAT SIMPLE
Purple Medical Blog had written previously about another study called Adjustable Gastric Banding and Conventional Therapy for Type 2 Diabetes. Researchers divided obese people with Type 2 diabetes into two groups. One group of obese diabetics got weight loss surgery, laparoscopic adjustable gastric banding and the other group of diabetics got conventional diabetes therapy with a focus on weight loss by lifestyle change. The researchers found that "participants randomized to surgical therapy were more likely to achieve remission of type 2 diabetes through greater weight loss. These results need to be confirmed in a larger, more diverse population and have long-term efficacy assessed".

"The study, of 60 patients, showed that 73 percent of those who had the gastric banding surgery had complete remissions of diabetes, meaning all signs of the disease went away. By contrast, the remission rate was only 13 percent in those given conventional treatment, which included intensive counseling on diet and exercise for weight loss, and, when needed, diabetes medicines like insulin, metformin and other drugs". Type 2 diabetes is the more common form of diabetes. Doctors have known for some time that weight loss tends to improve Type 2 diabetes. It tends to appear in older people and can be due to a lack of sensitivity of the insulin receptors in the body. Type 2 diabetes is more likely to be treated with pills than insulin shots.
The LA article writes "There is strong evidence that surgery -- especially gastric bypass surgery, which makes the stomach smaller and allows food to bypass part of the small intestine -- causes chemical changes in the intestine, says Dr. Jonathan Q. Purnell, director of the Bionutrition Unit at Oregon Health & Science University. The small intestine has been thought of simply as the place where digestion occurs".
"But researchers now suspect it has other functions related to metabolism. (Gastric Bypass) Surgery somehow alters the secretion of hormones in the gut that play a role in appetite and help process sugar normally".
