As a diabetic, you may be vulnerable to certain skin conditions such as diabetic blisters. That is one of the reasons why it is important to monitor your health. This means understanding the causes and prevention of diabetic blisters and also taking note of the condition of your skin.

Diabetic blisters are like burn blisters and they tend to appear on the arms and lower legs, particularly on hands and feet. Unlike burn blisters, they are painless and tend to heal on their own. Let us look at the causes and prevention of diabetic blisters.


The cause of diabetic blisters is unknown. However, they can be prevented with a few simple routines as listed below. Moreover, some people are more prone to blisters than others. For instance, Candida albicans, a type of yeast that can cause fungal infection, may be the cause of blisters in people who have diabetes. You are also more likely to get diabetic blisters if your blood sugar level isn’t under control. People with diabetic neuropathy, a nerve damage that decreases one’s sensitivity to pain, are also more likely to get blisters. A correlation has also been found to peripheral artery disease.
