NCT04432025

Brief Summary

The aim of this study is to investigate the continued usage of standard diabetes medications in the post operative period following bariatric surgery to determine whether this approach may improve long term diabetes control. At present, the standard of treatment in patients with type 2 diabetes is that all medication is stopped in the immediate postoperative period and only re-started if symptoms of diabetes re-emerge. Although a large proportion of patients with diabetes will initially go in to remission, 80% experience relapse within five years. This study is needed to determine whether continuing medications is not only safe but will improve long term outcomes for patients with diabetes.

Study Arms (2)

Control

ACTIVE COMPARATOR

Patients will undergo bariatric surgery- either roux en y gastric bypass or sleeve gastrectomy. Long term diabetes care will be under the supervision of their primary care provider/general practitioner

Procedure: Bariatric surgery

Intervention

EXPERIMENTAL

Patients will undergo bariatric surgery- either roux en y gastric bypass or sleeve gastrectomy and will have ongoing goal directed medical treatment for their T2DM, titrated to specific end points for BP, HbA1c and lipids.

Procedure: Bariatric surgery + goal directed medical therapy

Interventions

Patients will undergo bariatric surgery (RYGB or SG) with goal directed medical therapy titrated to specific end points for BP, HbA1c and lipids

Intervention

Patients will undergo bariatric surgery (RYGB or SG) with usual care for diabetes mellitus undertaken by their primary care provider/general practitioner
