At what age does hereditary body odor (bromhidrosis) typically start?

Generally, hereditary axillary osmidrosis (underarm odor) usually begins to manifest between the ages of 12 and 18, although the exact timing may vary among individuals. Detailed analysis is as follows:

Axillary osmidrosis typically refers to the odor caused by bacterial breakdown of secretions from the axillary apocrine glands. Hereditary cases generally start producing odor between the ages of 12 and 18. During this period, increased hormone secretion enhances apocrine gland activity, leading to excessive perspiration and resulting in a pungent odor. The exact onset time may differ depending on individual factors.

For mild cases of axillary osmidrosis, special treatment is usually unnecessary. Regular bathing, frequent clothing changes, wearing loose-fitting clothes, and maintaining clean and dry underarm areas are generally sufficient. For patients with more severe symptoms, treatments such as laser therapy or high-frequency electroacupuncture may be used under a physician's guidance. These treatments directly target the hair follicles and destroy the apocrine glands, achieving therapeutic effects.

Maintaining good lifestyle habits and personal hygiene, avoiding prolonged exposure to hot and humid environments, and reducing consumption of spicy and irritating foods such as garlic, ginger, and chili peppers can help prevent the occurrence of axillary osmidrosis.
