How can one determine whether they have axillary odor (body odor in the armpits)?

To determine whether you have axillary odor, you can: 1. Smell test: The most direct method is to judge by smell. Wipe under your armpits with a clean tissue or handkerchief, then smell it. If there is a pungent, sour odor, it may indicate axillary odor. 2. Observe earwax: Patients with axillary odor sometimes have oily ears, meaning their earwax is wet, sticky, or powdery. 3. Examine your underwear: Pay attention to the underarm area of your clothing for signs of yellowing or discoloration, which may also indicate axillary odor. 4. Inspect underarm hair and sweat: Check if there are white or light yellow secretions on the underarm hair and whether the sweat feels sticky or has an odor. 5. Family history: Axillary odor is related to heredity. If there is a family history of axillary odor, your likelihood of having it increases.
