What is the primary characteristic of hirsutism?

Hirsutism is specifically characterized by excessive body hair in females, particularly in areas where males generally grow hair, such as the face, chest, and back. This condition results from an increased level of androgens (male hormones) in the body, which can lead to a male-pattern hair distribution in women. It is important to note that hirsutism is not merely about the presence of excess hair; it also includes the context of gender and hormonal levels.

While excessive facial hair can be seen in males, it does not define hirsutism as it specifically pertains to excessive hair in females. The other options, including the enlargement of hands and feet and excessive sweating, describe different medical conditions and symptoms that are not related to hair growth patterns. Understanding hirsutism in the context of hormonal balance and its effects on women is crucial to distinguishing it from other conditions.
