Benefits of Insulin Supplementation for Correction of Hyperglycemia in Patients With Type 2 Diabetes

The management of patients with Type 2 diabetes involves treatment with two different types of insulin injections to control blood sugar levels. The doses of the two types of insulins, glargine insulin and aspart insulin are adjusted daily through the hospital stay based on blood sugar levels. Many times, in addition to glargine and aspart insulin at meals, additional small doses of aspart insulin are given to correct high blood sugar levels. It has not been determined if using these extra doses of aspart insulin to correct blood sugars before meals improves care of the patients. Studies done in the past indicate that blood sugar levels are well controlled on the standard treatment of the two insulins and that most patients do not need the small extra dose of insulin at bedtime. This study will test if insulin supplementation improves glycemic control and prevents hypoglycemia in insulin treated patients with type 2 diabetes mellitus.
