This is not a big surprise, since the morbidly obese do achieve great weight loss with the surgical approach.
Bariatric Surgery vs Intensive Medical Therapy for Diabetes
Research · March 31, 2014
In a 3-year trial, researchers compared intensive medical therapy alone or intensive medical therapy plus Roux-en-Y gastric bypass or sleeve gastrectomy for effectiveness in lowering glycosylated hemoglobin to ≤ 6.0%. At 3 years, 5% of the patients in the medical therapy group vs 38% of those in the gastric bypass group (P < .001) and 24% of those in the sleeve gastrectomy group (P = .01) achieved glycemic control.
Among obese patients with uncontrolled type 2 diabetes, 3 years of intensive medical therapy plus bariatric surgery resulted in glycemic control in significantly more patients than did medical therapy alone. Analyses of secondary end points, including body weight, use of glucose-lowering medications, and quality of life, also showed favorable results at 3 years in the surgical groups, as compared with the group receiving medical therapy alone.
