The three main symptoms of the disease are “three more and one less”, and more food, more drink, more urine, but the weight is decreasing. There are many people with diabetes in China, and the number is increasing every year. The disease is also a more dangerous disease, and if not handled properly, it can easily lead to various complications. What are the skin lesions caused by diabetes? A. Diabetic rash This skin change occurs in front of the lower legs. It starts as a round or oval dark red papule, only about 0.3 cm in diameter. Some of these papules are present scattered, while others are clustered together and have a flaky surface. After the rash subsides, localized atrophy or hyperpigmentation will appear on the skin. This itch is a generalized and very persistent one. In the early stages of diabetes, this itching symptom is very common. When the patient is treated and there is significant remission, the itching may also gradually disappear. In 1/10 of diabetic patients, there are peripheral neuropathies. For example, abnormal sensation, including having numbness, pins and needles, pain or burning sensation in the skin, especially in the patient’s feet, is more likely to occur. Therefore, some patients often go to dermatology for examination before diabetes is detected. Third, diabetic maculopathy Diabetic maculopathy is a skin complication that occurs on the patient’s hands and feet. These blisters occur suddenly and repeatedly without any conscious symptoms. The blisters vary in size, have thin walls, are filled with clarified fluid, and have no redness on the outside of the blisters. They usually heal spontaneously after a few weeks or leave pigmentation on the skin after they have subsided. This herpetic disease often occurs in patients with long duration of diabetes, poor general condition and serious complications, so the patient’s prognosis is poor and can even lead to death. Fourth, the skin infection when the onset of diabetes, the patient’s blood sugar is elevated, the skin tissue glycogen content is also increased, which creates a good environment for the infection of mold, bacteria. One third of diabetic patients have skin infections as a complication. For example, patients often suffer from bacterial infections such as boils, folliculitis, impetigo and carbuncles. Diabetic patients are prone to ringworm such as ringworm of the hands, ringworm of the body, ringworm of the femur, and ringworm of the feet. As you can see, diabetes is also a very dangerous disease that can bring about various serious complications that can threaten our health and even our lives, so we hope that we can treat the disease early.
