Diabetes sufferers with swinging blood sugar ranges at excessive danger of coronary heart illness


A new study has shown that patients with type 2 diabetes who often have fluctuating blood sugar levels are at increased risk of developing heart disease as well.

Patients who suffer from type 2 diabetes and suffer from extreme fluctuations in their blood sugar levels have an increased risk of heart disease – according to the results of a new study.

The results of the study were published in the journal ‘Diabetes, Obesity and Metabolism’. The study examined more than 29,000 patients with type 2 diabetes over a period of two years. Patients who already had heart disease were excluded.

The American Diabetes Association recommends adults with diabetes maintain an A1c, average blood sugar level for the past two to three months, of less than 7 percent to reduce complications from diabetes such as heart disease.

However, studies, including this one, have shown that large swings in blood sugar levels can be a better predictor of diabetic complications than the A1c value at each individual doctor’s visit.

“The underlying mechanism for the relationship between large fluctuations in blood sugar levels between doctor appointments and a high risk of heart disease in patients with type 2 diabetes is unclear,” said Dr. Gang Hu, Associate Professor and Director of the Chronic Disease Epidemiology Lab at Pennington Biomedical Research Center.

“It is possible that episodes of severely low blood sugar are the link,” added Dr. Hu added. Research has shown that large differences in blood sugar levels are linked to poor health outcomes and even death. A 2017 Johns Hopkins study found that a third of people with diabetes who were hospitalized for a severe episode of low blood sugar died within three years of the incident.

“We recommend that patients and their doctors undertake therapies that can reduce large swings in blood sugar levels and the associated episodes of severe low blood sugar levels,” said Dr. Hu.

“Our results suggest that measuring the fluctuations in blood hemoglobin A1c levels over a period of time – say six months to a year – could serve as an additional blood sugar target,” he concluded.
