Background: Patient management after bariatric surgery is important in controlling patients' diabetes and recurrence prevention. This study aimed to meet the medical managements of patients with diabetes 6 months after the bariatric surgery. Materials and Methods: This cross-sectional study was performed on 77 type 2 diabetes patients' candidates for bariatric surgery (Roux-en-Y [RYGP] and Omega). Postoperative implementation protocol was one-third of insulin for patients taking long-term insulin and the discontinuation of medications for patients of oral antidiabetic agents. Blood glucose (BG) level was checked regularly by the patients at home and the necessary medical management was applied. The weight, BG and HbA1C levels, and use of oral antidiabetic agents and insulin were assessed and recorded before 1, 3, and 6 months after the surgery. Results: BG levels and HbA1C percentage in the 1st, 3rd, and 6th months after the intervention in Omega group were significantly lower than RYGB group (P value < 0.05). At 1 and 3 months after surgery, the mean insulin dose received by the Omega and RYGB groups was reduced to <30 units/day and 10 units/day, respectively, following the management protocol in this study. Moreover, 23.1% and 7.7% of patients in RYGB group and 12.1% and 3% of patients in Omega group took oral antidiabetic agents 1and 3 months after surgery, respectively. Insulin and oral antidiabetic agents were completely discontinued 6 months after the surgery. Conclusion: The long-term management and support of the patients by the implementation of a standard protocol after surgery are of great significance in obtaining the optimal outcome after bariatric surgery.
