Microvascular Complications Associated With Rapid Improvements in Glycemic Control in Diabetes
Abstract
Aggressive glycemic control has become the standard clinical approach to diabetes care. Unintended consequences have included the development of microvascular complications that are related to the rapidity of glycemic improvement. Diabetic neuropathy may develop in up to 10% of individuals secondary to aggressive glycemic control. The neuropathy is predominantly small fiber sensory and autonomic, and the severity of the neuropathy is tied to the change in the glycosylated hemoglobin A1C. Other microvascular complications such as retinopathy and nephropathy are common and may occur in parallel with the neuropathy. Eating disorders are a common comorbid risk factor. Individuals with uncontrolled diabetes for prolonged periods, particularly those with a history of eating disorders involving insulin restriction for calorie purging, are at high risk for developing treatment-induced microvascular complications. Gradual glycemic improvements should be encouraged but future research is needed to optimize treatment and prevention strategies.
