A Danish study examines the link between vitamin D and cardiovascular autonomic neuropathy associated with diabetes.
Adults with both type 1 and type 2 diabetes who have vitamin D levels that are too high or too low could have an increased risk of cardiovascular autonomic neuropathy (CAN).
This condition occurs when the nerves that control heart rate become damaged. This can cause heart rate to stay high even during rest and can also result in lower than normal blood pressure.
The study was published in the online journal Diabetes Medicine.
