Though diabetic blisters are painless, they are certainly a cause of concern because these blisters might burst open and cause infection. The chances of an infection occurring is higher when there is a blister on the feet. This is a cause for concern as diabetic foot infections can lead to diabetic foot ulcers.
Diabetes and feet – Diagnosis of diabetic blisters
Diabetic blisters are self-evident and look like sores that arise after a burn. These diabetic blisters are known to occur more in people with diabetic neuropathy and poor blood circulation. They are painless, but cause itching. Some of these blisters do subside in a matter of weeks with proper blood glucose control. However, if these blisters occur on the feet, it is very important to prevent diabetic foot infection.
Diabetic blisters are clearly visible and do not need any special diagnostic tests in order to determine the presence of a diabetic blister. Generally, diabetes doctors conduct other tests like fasting blood glucose test, postprandial blood glucose test, and an HbA1c test in order to assess the patient’s diabetes.
