Sweaty hands are not necessarily caused by kidney deficiency, but may also be caused by other reasons, and need to be combined with other clinical manifestations to diagnose whether it is kidney deficiency, and can not be generalized. The causes of hand sweating are many, mainly divided into non-disease factors and disease factors, non-disease factors include mental tension, anxiety, after exercise, consumption of spicy stimulating food or in a special period, such as women in pregnancy and childbirth, menopause, etc. Disease factors include restrictive hyperhidrosis, yin deficiency, kidney deficiency, etc. It may also be caused by the cervical spine. If hand sweating is accompanied by soreness and weakness of the waist and knees, irritability, insomnia and dreaminess, then it is considered kidney yin deficiency; if it is accompanied by dizziness and tinnitus, weakness, fear of cold and other symptoms, then it is considered kidney yang deficiency. Therefore, if you have sweaty hands, it is recommended that you go to a Chinese medicine physician to confirm the diagnosis, not to judge by yourself and choose the medicine at will, but to choose the medicine under the guidance of a doctor.
