Sweaty hands and feet may be kidney deficiency, but the diagnosis of kidney deficiency needs to be combined with other manifestations, and cannot be judged by this point alone. There are more reasons for sweaty hands and feet, and most of them are considered to be deficiency. In Chinese medicine, there are many types of deficiency, which can be broadly categorized as yin deficiency, yang deficiency, qi deficiency, blood deficiency, etc., combined with different parts, such as kidney deficiency can be categorized as renal yin deficiency, renal yang deficiency, renal qi deficiency, and renal essence deficiency. According to Chinese medicine theory, yin deficiency generates internal heat, i.e., kidney yin deficiency is prone to generate heat, which is often referred to as heat in the heart of the hands, feet and mouth, and is often referred to as “five heartburns” in clinical practice. Chinese medicine also believes that qi has a role in retaining fluids in the body, so when symptoms of qi deficiency occur, it can also lead to sweaty hands and feet, but because not only the kidneys can have qi deficiency, other parts of the body can also occur. Therefore, sweaty hands and feet may be caused by kidney deficiency, but it is not all caused by kidney deficiency. When sweaty hands and feet occur, you can go to the Chinese medicine department for consultation, and the doctor will make a comprehensive diagnosis by combining other symptoms, pulse, and tongue, and then carry out appropriate treatment after confirming the cause of the disease.
