Sweaty feet and kidney deficiency do not have much to do with each other. In addition to genetic factors and external factors, sweaty hands and feet are mostly blamed on the spleen and stomach. It may be caused by dampness and heat in the spleen and stomach. You should consult a Chinese hospital to identify the cause and choose Chinese medicine to regulate it. Some people have abundant sweat glands in their feet and tend to sweat easily, which is often related to genetic factors. Some patients have rich and sensitive nerves that govern the sweat glands in the feet. Whenever they walk, run, or even get nervous or emotional, the sympathetic nerves become highly excited and the sweat glands secrete sweat. Another part of the patients is caused by damp heat in the spleen and stomach, which is reflected in the hands and feet, and can show obvious sweating symptoms, accompanied by heavy limbs and other manifestations. In addition to this, a few people are caused by external factors, such as wearing shoes that are not breathable and the sweat secreted cannot evaporate in time. Patients with sweaty feet should pay attention to cleanliness and keep their skin dry. Change socks regularly, usually should not wear non-breathable shoes, so as not to cause excessive foot sweat, foot odor intensified. Actively eliminate predisposing factors, such as foot sweat, tinea pedis, etc.
