Hyperhidrosis is generally a disease caused by one's own endocrine imbalance or hormonal levels. The most characteristic symptom of this disease is increased sweating, such as excessive sweating from the armpits, groin, or palms, especially after exercise or staying up late, but there is no abnormal odor. Bromhidrosis is a type of hereditary disease, characterized by excessive sweating from both armpits and a strong odor, which can start showing symptoms from puberty. Bromhidrosis cannot be completely eradicated, while hyperhidrosis can be cured through proper medical treatment. The most common treatment for bromhidrosis is surgical removal of the large sweat glands, which can reduce or alleviate the odor, but cannot eradicate it completely.
