What do we call a lack of perspiration due to an underactive gland?

Anhidrosis refers to a condition characterized by a decreased ability to sweat, which is a result of underactivity in the sweat glands. Sweating is a crucial physiological process that helps regulate body temperature and maintain homeostasis. When these glands are not functioning adequately, it can lead to an inability to effectively cool the body through perspiration, which can have serious implications, especially in hot environments or during physical exertion.

This condition can have various causes, including certain medical conditions, skin disorders, and even medications that affect skin and gland function. It's important to differentiate anhidrosis from other terms, such as hyperhidrosis, which signifies excessive sweating, and oligohidrosis, which indicates reduced but not absent sweating. Xeroderma, on the other hand, refers to dry skin rather than issues with perspiration itself. Understanding these distinctions is vital for recognizing and addressing issues related to skin health and gland function.
