Does Diabetes Cause Foot Blisters?

People with diabetes can occasionally develop blisters on the backs of their feet, explains the American Diabetes Association. These blisters most often develop in patients already suffering from nerve damage called diabetic neuropathy.

Diabetic blisters resemble burn blisters and typically heal by themselves without any scaring in roughly three weeks, according to the American Diabetes Association. These blisters are usually painless and have no redness. There is no treatment for diabetic blisters aside from bringing blood sugar levels under control. Other skin complications caused by diabetes include diabetic dermopathy, a condition that causes changes in the small blood vessels resulting in light brown and scaly patches, and eruptive xanthomatosis, a condition that causes firm, yellow, pea-like enlargements on the backs of the feet, legs, hands, arms and buttocks.
