What condition is characterized by profuse sweating?

The condition characterized by profuse sweating is known as diaphoresis. This term refers specifically to excessive perspiration that can occur during various circumstances, including physical activity, anxiety, fever, or certain medical conditions. Diaphoresis is an important clinical sign as it may indicate underlying health issues that require attention, such as hyperhidrosis or systemic conditions like infections or endocrine disorders. It is distinct from normal sweating, often indicating a more pronounced physiological response.

Other options represent different medical conditions: diastole refers to the phase in the cardiac cycle when the heart muscle relaxes, cyanosis indicates a bluish discoloration of the skin due to inadequate oxygenation, and croup is a respiratory condition commonly affecting young children, characterized by a barking cough and stridor. These terms are unrelated to the phenomenon of sweating.
