Many people have no idea what causes blisters on diabetic feet. For ordinary people, there are two main reasons for blisters that are more familiar to everyone, one is burns, but wear and tear on shoes. And for diabetic patients, in addition to these two causes, there is another must pay attention to. Here, I will briefly share with you the common causes of blisters in diabetic patients. First of all, we are familiar with burns. Most blisters are due to burns, but most are accidents, such as accidentally breaking a soup bowl or kettle. But for diabetics, hot water can also burn when you wash your feet. You may wonder, can you not feel the temperature of the water? For us ordinary people it can, but for diabetic patients there are risks. The chance of scalding increases when there is neuropathy in the distal extremities (especially in the lower extremities). This is because, after the development of neuropathy, the patient’s sensitivity to temperature is reduced, when using hot water to soak the feet, the water temperature is high also do not know, there will be burns, which is also the reason why most diabetic foot patients appear blisters. Second, wearing shoes wear. In particular, wearing ill-fitting shoes, new shoes, leather shoes, etc., can also lead to the appearance of blisters. Diabetic patients may not feel the abnormality and pain due to the lower limb lesions, and by the time they are found, they are often already badly worn out. Third, lower limb ischemia. Due to vascular lesions, resulting in narrowing or even occlusion of the arteries in the lower extremities, the tissues of the lower extremities will be damaged due to prolonged ischemia, and the extravasation of tissue fluid will form blisters, and sometimes blood blisters. Once blisters appear because of lower limb ischemia, the wound healing does not get sufficient blood and nutrient supply, and there is a greater chance of infection and ulceration, and a greater chance of triggering diabetic foot. These are the common causes of blisters in diabetic patients. Since diabetic patients have high blood sugar and high tissue fluid nutrition, wounds are easily infected and difficult to heal, so the chances of developing a diabetic foot ulcer after the appearance of blisters are high. If a diabetic foot ulcer occurs, do not worry too much, but you should not treat it blindly. You should be promptly referred to a department or hospital specializing in the treatment of diabetic foot to receive systematic treatment in order to quickly control the infection. It is recommended that a mature MDT multidisciplinary joint treatment center is preferred to avoid amputation.
