Sweaty palms may be kidney deficiency, but the performance of sweaty palms alone is often not enough to diagnose kidney deficiency. There are more conditions that cause sweaty palms, and normal people also have sweaty palms in a state of mental stress. Kidney deficiency is generally classified clinically into kidney yin deficiency and kidney yang deficiency, both of which have different symptoms. Chinese medicine believes that yin deficiency is prone to internal heat, so kidney yin deficiency often manifests itself in the form of irritable heat in the five hearts, i.e., the palms of both hands, feet and feet, and the heart is prone to heat, and the patient often feels irritable. In contrast, Yang deficiency tends to produce cold, so patients with kidney Yang deficiency tend to have a fear of cold, cold hands and feet, without sweating. In addition, sweaty palms can also be caused by other reasons, such as stomach yin deficiency and fire-heat internal depression. In addition, normal people with mental tension and congenital genetics can also cause the palms to sweat easily, so it is not always a kidney deficiency. When the palms of the hands sweat, it can be considered a kidney Yin deficiency in the kidney deficiency, but generally not a kidney Yang deficiency. And from a Western medicine perspective, hyperhidrosis can also cause this phenomenon.
