"Is a Strong Odor Under the Armpits a Sign of Body Odor (B.O.) or狐臭 (Fox Odor)?"

A strong odor emanating from the underarms may be indicative of body odor (bromhidrosis), or it could stem from inadequate personal hygiene, hyperhidrosis, folliculitis, and other medical conditions. It is recommended that patients promptly consult a physician for diagnosis and treatment under medical guidance.

1. Body Odor (Bromhidrosis): Neglecting personal hygiene and excessive sweating in the axillary region can foster bacterial growth, leading to unpleasant odors. Regular bathing can help mitigate this issue, and medications such as Aluminum Chloride Hexahydrate Solution and Tolonium Chloride Solution can be prescribed for management.

2. Inadequate Personal Hygiene: Failure to maintain proper hygiene by not changing clothes or cleaning the underarms promptly can result in excessive sweating and subsequent odor. Special treatments are generally not necessary; instead, focusing on regular bathing and frequent clothing changes is advised.

3. Hyperhidrosis: Caused by genetic factors or mental stress, hyperhidrosis manifests as excessive sweating from the axillary apocrine glands, contributing to underarm odor. Treatment may involve medication, such as Oryzanol Tablets and Vitamin B1 Tablets, administered under a doctor's supervision.

4. Folliculitis: An inflammatory reaction of hair follicles caused by Staphylococcus aureus infection, folliculitis presents as red papules centered on hair follicles, accompanied by itching and pain. When folliculitis affects the axillary region, it can cause the aforementioned symptoms. Topical treatments like Mupirocin Ointment and Fusidic Acid Cream can be prescribed for management.

Additionally, conditions like diabetic ketoacidosis can also lead to similar issues. Maintaining a positive mindset and avoiding emotional stress is crucial in daily life.
