Can bromhidrosis (fox odor) develop suddenly?

Body odor (bromhidrosis) does not typically develop suddenly; it is primarily caused by abnormal apocrine gland development or genetic factors.

Bromhidrosis is a relatively common dermatological condition. Overactive apocrine glands in the axillae may lead to increased sweating and an accompanying unpleasant odor. This condition develops gradually rather than appearing abruptly. Genetic factors play a significant role: if one or both parents have bromhidrosis, their children may inherit the predisposition. The characteristic odor usually becomes noticeable during periods of increased axillary sweating—such as during physical activity—but does not manifest suddenly.

If bromhidrosis is suspected, prompt evaluation by a dermatologist at a reputable hospital is recommended. Diagnostic imaging—such as color Doppler ultrasound or CT scanning of the axillae—can accurately assess apocrine gland development. Based on the findings, treatment options—including laser ablation or surgical excision of the apocrine glands—may be recommended under a physician’s guidance. These procedures help reduce sweat production and can provide a definitive cure for bromhidrosis.
