Is lowering glucose levels always beneficial for diabetes patients?

Is lowering glucose levels always beneficial for diabetes patients?
10th April 2012

It is thought to be common knowledge that lowering glucose levels is essential for the outcomes of diabetes patients.

However, a new study has thrown into question this assertion, by showing that in those with heart failure higher levels of glucose could be more beneficial.

Researchers from the University of California, Los Angeles claim that greater blood glucose levels could improve survival rates among those diabetes patients with heart problems.

Levels of the marker glycosylated haemoglobin, which is used to track glucose in the body, were compared in those with and without diabetes who had advanced heart failure.

It was found that for patients with both heart failure and diabetes, mortality risk decreased by 15 per cent for every unit increase in the marker.

Dr Tamara Horwich, senior author on the study, commented: "We may find that doctors who treat patients who have both advanced heart failure and diabetes may not need to focus on aggressively lowering blood sugar, but rather keep it under moderate control."
