DSS: Diabetes Surgery Study - Intensive Medical Management of Type 2 Diabetes, With and Without Gastric Bypass Surgery
Completed · Not applicable
Conditions studied: Type 2 Diabetes, Cardiovascular Disease
In brief
The present study is the first stage of a research program whose ultimate goal is to conduct a randomized clinical trial involving type 2 diabetics with BMI from 30.0 to 39.9 kg/m2. This program will determine the relative effectiveness of RYGB combined with intensive medical management (IMM), versus IMM alone, in reducing CVD event rates and mortality in patients with poorly controlled diabetes. IMM will include rigorous lifestyle modification for weight loss and stepped pharmacologic treatment for diabetes and other CVD risk factors. The proposed study is a randomized trial which will provide an assessment of the efficacy of treatment, in reducing CVD risk factors and also assessing the feasibility, cost, and safety of a larger trial.
