The presence of an ammonia-like odor in perspiration often signals a physiological process related to protein metabolism. When the body lacks sufficient carbohydrates or is subjected to intense or prolonged physical activity, it may begin to break down protein for energy. A byproduct of protein breakdown is ammonia, which the liver converts to urea. If urea production exceeds the kidneys’ capacity for excretion, excess urea may be eliminated through sweat, resulting in the characteristic smell.
Understanding the source of this odor can provide valuable insights into an individual’s metabolic state and dietary habits. Identifying the underlying cause may lead to adjustments in nutritional intake, particularly increasing carbohydrate consumption to fuel energy needs and reduce protein catabolism. In some instances, this odor may indicate underlying medical conditions, requiring further investigation to ensure proper diagnosis and treatment.
