What is hyperhidrosis?

Hyperhidrosis is defined as excessive perspiration that occurs beyond what is necessary to regulate body temperature. This condition can affect various parts of the body, including the palms, soles, underarms, and face. Individuals with hyperhidrosis may experience discomfort and social embarrassment due to the excessive sweating, which can occur even without triggering stimuli like heat or physical exertion.

In contrast to the other conditions listed, excessive perspiration specifically refers to an overactive sweat response, making the distinction clear. Excessive hair growth refers to a condition known as hirsutism, which is unrelated to sweating. Dry skin is a different dermatological issue that does not involve perspiration. Severe acne pertains to a skin condition involving inflamed/comedonal lesions, which does not correlate with the mechanism of excessive sweating.

Thus, identifying hyperhidrosis as excessive perspiration captures its essence, providing a precise understanding of the condition and its implications.
