Two Years Remission of Type 2 Diabetes Mellitus after Bariatric Surgery.

Objective: To determine the influence of bariatric surgery on remission of type 2 diabetes mellitus (T2DM) in obese patients along with improvements in other obesity-associated comorbidities.

Study Design: Observational study.

Place And Duration Of Study: Doncaster and Bassetlaw NHS Trust, UK, from August 2010 to August 2018.

Methodology: All the cases of bariatric surgery in obese patients with T2DM who had completed 2 years of follow up were included in the study. Remission of T2DM was defined as glycated hemoglobin (HbA1C) <48 mmol/mol (<6.5%) or fasting blood sugar of <7.0 mmol/L, not on hypoglycemic agents 2 years after having bariatric surgery. Student's t-test was used to see any difference in baseline HbA1C, BMI, percentage of weight loss, and duration of diabetes between remitters and non-remitters.

Results: Two years follow-up data after bariatric surgery for remission of T2DM or otherwise was available for (n=121) patients. Majority (70.2%, n=85) were females and (29.8%, n=36) were males. Mean age was 48.21 ±9.77 years. Eightythree (68.6%) patients achieved remission of T2DM at 2 years and 31.4% (n=38) did not. Remission of other comorbidities was 33.3% (n=53 out of 159) for hypertension (HTN), 50.8% (n=60 out of 118) for dyslipidemia, 67.2% (n=43 out of 64) for obstructive sleep apnea (OSA), 52.1% (n=37 out of 71) for gastro esophageal reflux disease (GERD), 25.7% (n=18 out of 70) for asthma, and 23.3% (n=24 out of 103) for depression.

Conclusion: Bariatric surgery effectively achieves remission of T2DM and other obesity associated comorbidities.
