Hyperhidrosis is divided into two categories: primary hyperhidrosis and secondary hyperhidrosis. Primary hyperhidrosis: It is a pathology in which sweating increases significantly compared to normal under normal conditions (ambient temperature and humidity, mental and emotional). The sweating is often aggravated by nervousness, hot food and spicy food, and increased ambient temperature and humidity. Clinically, hyperhidrosis is classified as head sweating (often accompanied by excessive sweating in the axillae and/or bilateral palms), hand sweating (often accompanied by excessive sweating in the soles of the feet and/or axillae), axillary sweating, and body sweating according to the location of sweating. Secondary hyperhidrosis is caused by neuroendocrine and other systemic diseases (e.g. hyperthyroidism, diabetes, hypoglycemia, poisoning, drug side effects, cardiovascular disease, respiratory failure, carcinoid syndrome, Hodgkin’s disease). Hyperhidrosis can be divided into generalized hyperhidrosis and localized hyperhidrosis according to the location of sweating. Generalized hyperhidrosis is mostly secondary hyperhidrosis, while localized hyperhidrosis is mostly primary hyperhidrosis.
