Causes and Symptoms of Axillary Odor

Causes of Axillary Odor: 1. Sweat secretion: Excessive secretion from the apocrine glands located under the skin of the armpits leads to axillary odor, which becomes more noticeable in summer due to increased sweat gland activity. 2. Genetic factors: Axillary odor has a clear hereditary component; if either parent has body odor, the likelihood of inheritance is higher. 3. Poor habits: Poor personal hygiene, such as wearing tight clothing, can prevent sweat from evaporating, promoting bacterial growth and resulting in unpleasant odor. 4. Puberty: Axillary odor commonly develops during adolescence, and symptoms may worsen as sweat glands mature. Symptoms of Axillary Odor: 1. Unpleasant odor: A strong, offensive smell emanates from the armpits, often accompanied by hyperhidrosis (excessive sweating). 2. Changes in underarm hair: Sticky substances or tiny crystalline particles may appear on the underarm hair. 3. Clothing discoloration: Clothes worn close to the armpits may become yellow-stained and emit an unpleasant odor. 4. Oily ears: Patients often have oily ears, with wet, sticky earwax. The above are the main causes and typical symptoms of axillary odor. Patients should seek medical advice promptly and take appropriate measures for prevention and treatment.
