How can I determine if I have body odor (bromhidrosis)?

To determine whether you have bromhidrosis (body odor), the following suggestions are recommended: 1. **Odor test**: After vigorous exercise or sweating, wipe your underarms with a clean, odorless tissue or handkerchief, then smell the tissue or handkerchief to check for any unpleasant, fishy odor. This is the most direct and effective method. 2. **Family history observation**: Bromhidrosis tends to be hereditary. If there is a family history of this condition, your likelihood of having it may increase. 3. **Examine sweat and clothing**: The sweat of individuals with bromhidrosis is usually oily and does not evaporate easily. It contains high levels of proteins and fats, which may cause yellow staining or discoloration in the underarm areas of clothing. 4. **Observe underarm hair and earwax**: Individuals with bromhidrosis may have abnormally oily substances or thick liquid on their underarm hair, and the hair secretions may become moldy or stick together. Additionally, people with this condition often have oily (wet and sticky) earwax, although this is not always the case. 5. **Professional diagnosis**: If you still have doubts after performing self-tests, it is recommended to consult a professional physician or dermatologist for a definitive diagnosis. The doctor may make a diagnosis based on the patient's symptoms, family history, and necessary examinations.
