Poor diabetes control can lead to increased risk of serious infections, study shows

A new study has shown that diabetes patients with the poorest control of their blood sugars face the highest risks of hospitalisation and death due to infections.

The study, conducted by researchers at St George’s, University of London, analysed the electronic GP and hospital records of more than 85,000 English adults aged 40 to 89 years with a diabetes diagnosis and a measurement of glycated haemoglobin, or long-term blood sugar, which is a marker of diabetes control. The researchers compared diabetes patients with poor control to those with good control, and to people without diabetes.
