Gastric bypass surgery has been proposed as an effective treatment strategy for type 2 diabetes mellitus (T2DM), but thus far algorithms for the management of T2DM immediately after surgery have not been established. The investigators designed an algorithm to achieve good glycaemic control in patients with insulin-requiring T2DM upon discharge after gastric bypass surgery, and evaluated this algorithm for feasibility, efficacy, and safety.

Study Population

This study was a prospective study including morbidly obese patients with insulin-requiring type 2 diabetes immediately following gastric bypass surgery.

On admission to hospital patients' regular oral hypoglycaemic medication and insulin were stopped, and short-acting insulin was given based on capillary glucose monitoring according to a routine care insulin sliding scale.

Upon discharge 2-3 days after surgery, patients were prescribed metformin 1g twice daily and glargine at a dose equivalent to the insulin requirement during the 24 hours prior to discharge. Patients were instructed to contact the metabolic physician every day via text(SMS) message or telephone to report fasting capillary blood glucose levels obtained using Accu-Check Advantage. Based on the reported glucose values insulin dosages were then adjusted daily according to a titration schedule.

  • Age >18yr,
  • Having undergone gastric bypass surgery,
