  Purpose

Specific Aims & Hypothesis Primary Aim: To evaluate laparoscopic bariatric surgery versus intensive medical weight management on indices of insulin resistance and resolution of type 2 diabetes among patients with BMI 30-35.

Hypothesis: Bariatric surgery is the most effective treatment to induce diabetes remission in obese diabetic patients BMI 30-35.

The primary outcomes will be assessed at 6 months: (1) within-patient change in insulin resistance after either bariatric surgery or initiation of intensive medical weight management, and (2) remission of diabetes, (i.e., fasting glucose <126mg/dL and glucose <200mg/dL two hours after a standard 75g oral glucose load without the use of anti-hyperglycemic medications). Insulin resistance will be assessed at randomization and at 6 months with the homeostatic model assessment of insulin resistance (HOMA IR) based on insulin and fasting glucose, as well as oral glucose tolerance tests with area-under-the-curve (AUC) measurement for insulin values. Medication discontinuation will be derived from electronic health records and patient self-report at 6 months. Secondary outcomes will include changes in HBA1c, weight, blood pressure, waist circumference, and levels of fasting lipids.

Primary Outcome Measures:
  • Insulin Resistance [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Within-patient change in insulin resistance after either bariatric surgery or initiation of intensive medical weight management, and remission of diabetes, (i.e., fasting glucose <126mg/dL and glucose <200mg/dL two hours after a standard 75g oral glucose load without the use of anti-hyperglycemic medications). Insulin resistance will be assessed at randomization and at 6 months with the homeostatic model assessment of insulin resistance (HOMA IR) based on insulin and fasting glucose, as well as oral glucose tolerance tests with area-under-the-curve (AUC) measurement for insulin values.


Secondary Outcome Measures:
  • Vitals status [ Time Frame: 6 Months ] [ Designated as safety issue: No ]
    changes in HBA1c, weight, blood pressure, waist circumference, and levels of fasting lipids

Criteria

Inclusion Criteria:

Patients eligible for study are adults (age ≥ 18) with type 2 diabetes who have a BMI 30-35, and are insured by Metroplus insurance, but otherwise meet NIH Consensus Criteria specifically (1) overweight for at least 5 years, (2) failure to lose weight with non-surgical means, (3) absence of medical or psychological contraindications, and (4) patient understanding of the procedure and its risks, and strong motivation to comply with the post-surgical regimen. Patients must have permission from their physician to participate in the study.

Exclusion Criteria:

Exclusions include being deemed unable to comply with the study protocol (either self-selected or by indicating during screening that s/he could not complete all requested tasks), participation in other obesity- or diabetes-related clinical trials, or diagnosis of cognitive dysfunction or significant psychiatric comorbidity.
