People with diabetes can sometimes develop blisters on their skin, also known as diabetic bullae or bullosis diabeticorum. Even though diabetes blisters are not a pleasant sight, they are usually painless and will heal naturally, without leaving scars.
Still, when it comes to diabetes, it’s always better to treat wounds with quick and proper care. This is because ordinary foot sores or blisters in a person with diabetes can sometimes turn into an ulcer which if not properly treated can lead to amputation.
These blisters are a rare symptom of type 1 diabetes, but sometimes they can even appear in those with type 2 diabetes. According to the International Journal of Diabetes in Developing Countries, they appear only in 0.5% of U.S. diabetes patients. Also, men are more prone to this skin disorder than women.
The most common places where diabetes blisters appear are feet, legs, and toes, but rarely can they show up on arms, hands, and fingers.
Diabetic blisters usually look like those when you get a burn, except that they are painless. They can reach up to 6 inches, usually in clusters. They are itchy, and the skin around them is swollen or red. These blisters are filled with clear, sterile fluid and rarely appear as a single lesion.
Even though the exact reason for the development of these blisters is not known, a lot of scientists believe it’s the reduced ability of a diabetic organism to sustain an injury. Moreover, these people usually suffer from nephropathy and diabetic neuropathy.
In some cases, the swelling caused by heart failure in people with diabetes might be reason enough to cause their appearance. Also, diabetes patients who’ve experienced several complications from their diabetes through the course of several years might experience diabetic blisters.
Another common cause of diabetic blisters is the fungal infection candida albicans, and wearing too tight shoes.
To avoid diabetic blisters, you should take proper care of your feet.
Diabetic blisters usually heal on their own within 2-4 weeks if you keep the area clean. But you should also know some other things to take care of them properly so that they can heal faster and prevent infection.
Therefore, if you have diabetes, regardless of type 1 or type 2, taking good care of your feet is a preventive measure when it comes to diabetic blisters.
