Received any antibiotic, probiotic, or prebiotic agents in the month before randomization 4. Pregnancy 5. Debilitating disease 6. Psychological conditions which may hamper patient?s cooperation 7.

Design outcomes

Primary

MeasureTime frame
Assess gut microbiota changes in mild obese (BMI 30-35 Kg/m2) diabetic patients after metabolic surgery and compare the gut microbiota with mild obese (BMI 30-35 Kg/m2) diabetic patients who underwent only advanced medical therapy

Secondary

MeasureTime frame
1. Determine the rate of biochemical remission of diabetes after metabolic surgery 2. Assess changes in metabolic, hormonal and inflammatory parameters after metabolic surgery versus advanced medical therapy 3. Study influence of patient characteristics in gut microbiota changes, as well as in metabolic, hormonal and inflammatory parameters, after metabolic surgery versus advanced medical therapy 4. Study associations between type 2 diabetes remission/improvement (metabolic, hormonal and inflammatory changes) and gut microbiota composition/adaptation after metabolic surgery versus advanced medical therapy
