Glucose variability and diabetic microvascular complications

Microvascular diabetes complications are linked to inadequate long-term diabetes control, as indicated by glycated haemoglobin (HbA1c) levels. Fluctuations in glucose levels are connected to oxidative stress, endothelial dysfunction, and inflammation, all of which are traditionally linked to the development of vascular damage. While some studies have linked glucose variability to macrovascular disease, its association with microvascular disease is still debated. The major question is whether short-term glucose variability should be regarded as an independent risk factor for microvascular complications in diabetes. This summary reviews research on glucose variability and its potential connections to diabetic retinopathy, nephropathy, and neuropathy. Current data indicate the need for further research into the parameters of both short-term and long-term glucose variability. These variability parameters may be important for selecting optimal treatment strategies and for estimating the risk of chronic diabetic complications.
