Cold sweaty hands and feet in men may be caused by kidney deficiency, but also by other diseases, such as liver qi stagnation, hypothyroidism, shock, etc. It is not a specific symptom of kidney deficiency. Mostly, there are problems with the cervical and lumbar spine. Men with cold hands and feet can be caused by a variety of reasons. If caused by kidney deficiency, the cause is a decrease in the kidney’s role in warming the body’s Yang, resulting in a weakening of the body’s consolidation of Qi and the leakage of semen, which manifests as sweaty hands and feet. In addition, if the body is weak in the presence of anemia and malnutrition, the symptoms of cold sweaty hands and feet may also occur. If the patient suffers from metabolic diseases, such as hypothyroidism, as well as shock, hypoglycemic coma, cold sweaty hands and feet may also appear. Therefore, the above symptoms should be determined by the doctor according to the patient’s specific performance, supplemented by relevant tests, to determine whether it is caused by kidney deficiency. If the symptoms of cold and sweaty hands and feet occur, it is recommended that the patient go to the endocrinology and Chinese medicine departments of the hospital for relevant examinations to confirm the cause of the disease and take appropriate treatment measures for the cause.
