Back sweating in men is usually called restrictive hyperhidrosis, with sweating on the trunk, bilateral palms and feet as the common clinical location. There are usually two major disease causes, which need to be identified from both TCM and psychology. If the identification is made from Chinese medicine, the cause of back sweating is usually caused by kidney deficiency and qi deficiency in men. If you’re looking at the heart medicine, there are several reasons why men often sweat in the back: 1. low blood sugar, when the blood sugar is lower than 3.9mmol/L, there are symptoms of low blood sugar and sweating around the body, especially in the back. 2. endocrine metabolic diseases, such as hyperthyroidism, hyperadrenocorticism. 3. endocrine disorders, such as the body estrogen and progesterone The above symptoms may also occur if there is an imbalance in the secretion of estrogen and progesterone.
