"Can you help me take a look at my legs?" Recently, many netizens posted photos on a topic about "judging high blood sugar by looking at my legs.". This hot search pointed out that brown patches and itching on the legs may be due to high blood sugar. "Sugar foot", as one of the complications of diabetes, makes many people panic: when these skin changes occur, does it mean that there is something wrong with blood sugar? Tang Wei, director of the Department of Endocrinology and diabetes Center of Jiangsu Provincial Government Hospital, said in an interview that changes in the skin of lower limbs are relatively common, and the causes are diverse and complex, which cannot be generalized. While diabetes patients are more common, when "sugar friends" have patches of skin pigmentation, itching and other symptoms, there may be more than one reason. Director Tang explained: "The skin lesions of diabetes may be the deposition of advanced glycosylation end products in the skin, diabetes peripheral neuropathy, peripheral vascular disease, skin malnutrition and microthrombosis." When skin symptoms occur, first identify whether there is a direct or indirect relationship with diabetes, or a concomitant problem other than diabetes. The reporter noticed that some netizens suffering from thyroiditis and thyroid nodules shared in the message section: "It is said that even if the thyroid is not good, it is the same. Although blood sugar is not high, the legs are also itchy and dry." Director Tang explained that in fact, whether it is hyperthyroidism or hypothyroidism, there may be abnormal skin manifestations. "Generally, it is directly related to the thyroid gland. We call it pretibial myxedema, and the skin will appear abnormal bulge and swelling. If it feels' hard ', there will be no obvious depression when pressing, and there will also be some abnormal pigmentation." In addition, those not directly related to diabetes, such as mosquito bites, eczema, dermatitis, pruritus, will also lead to skin lesions, but most of the symptoms are itching. If there is a burst after scratching, there will also be pigmentation during the healing process. Don't panic too much about this, treat it according to the cause and take preventive measures in daily life. Experts remind that for patients with diabetes, such skin symptoms are prone to occur, and further screening should be carried out to determine whether there are neuropathy, vascular abnormalities and other manifestations, such as venous thrombosis, arterial stenosis and so on. If there is local redness, swelling, and pain, it often indicates the presence of infectious inflammation. If not detected and treated in a timely manner, the subsequent development will also be faster and more severe. Some netizens also asked, "Can strengthening massage promote blood circulation and improve it?" Director Tang said that if it is caused by vascular supply disorders, local physical massage is effective, but if it is not caused by this cause, the effect is not good. In addition, we also need to remind that if it is directly related to diabetes, we must actively and steadily control blood sugar. If circulatory disorders have occurred, we should timely seek medical advice for intervention. Clinically, for different pathogenesis, we can use aldose reductase inhibitors, antioxidants, methyl B12 and other drugs to help improve the condition. (Lai Xin She)
