Abstract
Abstract
Aim
Roux en Y gastric bypass (RYGB) is known to ameliorate Type 2 Diabetes Mellitus (T2DM) in morbidly obese patients. We aimed to determine both the reduction in the glycosylated haemoglobin (HbA1c) and the number of anti-diabetic medications (including insulin) in diabetic patients undergoing RYGB over a five-year period.
Method
We reviewed data of diabetic patients (n = 530) who underwent RYGB from January 2012 – December 2017, including those with a minimum of a 2-year post-operative follow up (n = 47). Preoperatively, BMI, HbA1c and the number of anti-diabetic medications and the duration of T2DM since diagnosis were recorded. These measurements were repeated at the end of the two year follow up.
Results
At the time of enrolment in the bariatric programme, the median BMI was 42.5 (range, 31.7-61.5) kg/m2, mean duration of T2DM was 58 months and median HbA1c was 59 (37-118) mmol/mol. The mean number of anti-diabetic medications taken, including insulin, was 2. At the end of 2-year follow-up, the median BMI was 32 (range, 24-41) kg/m2 and HbA1c was 41(range, 33-91) mmol/mol. 15 patients (31.9%) still required anti-diabetic medication, 12 of whom had a diagnosis of T2DM for 3 years or more at time of enrolment.
Conclusions
RYGB is strongly associated with a resolution of T2DM in morbidly obese patients. In those who were not resolved, the number of anti-diabetic medications taken and HbA1c were reduced. The impact of the surgery is dependent on the duration of T2DM since diagnosis preoperatively.
