The condition of lacking or being without sweat is called:

• A. Alopecia
• B. Anhidrosis
• C. Capillary hemangioma
• D. Liposuction

Answer: (B)

Sweating is the body's cooling mechanism, produced by sweat glands. When the body cannot produce sweat, the condition is called anhidrosis. This term describes an absence of sweating, which can occur across the whole body or in specific areas and may result from nerve or gland issues, skin conditions, or certain medications. Without sweating, the body has a harder time regulating temperature, especially in hot environments or during exercise, increasing the risk of overheating.

Alopecia refers to hair loss, Capillary hemangioma is a benign vascular tumor, and liposuction is a cosmetic procedure to remove fat. These terms describe other conditions or procedures and are not related to the absence of sweat.
