Dramatic blood sugar control with gastric surgery
Radha Chitale
Gastric surgery controlled blood sugar better than intensive medical therapy among obese type 2 diabetics, according to the STAMPEDE trial, the results of which were presented recently at the recent 61st Annual Scientific Sessions of the American College of Cardiology meeting in Chicago, Illinois, US.
Patients who underwent Roux-en-Y gastric bypass surgery or sleeve gastrectomy achieved HbA1c control below 6 percent within a year in 42 percent (P=0.002) and 37 percent of cases (P=0.008), respectively, compared with 12 percent who received intensive medical therapy alone.

“Despite improvements in pharmacotherapy, fewer than 50 percent of patients with moderate-to-severe type 2 diabetes actually achieve and maintain therapeutic thresholds, particularly for glycemic control,” said researchers from the Cleveland Clinic in Ohio, US, Veterans Affairs Boston Healthcare System and Brigham and Women’s Hospital in Boston, Massachusetts, US.
“Observational studies have suggested that bariatric or metabolic surgery can rapidly improve glycemic control...”
The trial randomized 150 obese patients (mean age 49 years, mean body mass index 36 kg/m2, mean HbA1c 9.2 percent) with uncontrolled type 2 diabetes to receive intensive medical therapy alone, medical therapy plus Roux-en-Y gastric bypass surgery or medical therapy plus sleeve gastrectomy.
Intense medical therapy followed the guidelines of the American Diabetes Association and included lifestyle counselling, weight management, and drug therapy.
Patients randomized to surgery experienced significantly more weight loss compared with those receiving medical therapy after 12 months (-29.5 kg gastric bypass, -25.1 kg sleeve gastrectomy, -5.4 kg medical therapy, P
