Body Odor

Body odor (bromhidrosis) results from bacteria breaking down sweat and secretions, producing unpleasant smells. Contributing factors include hygiene, diet, medical conditions, and hormonal changes.

Body odor, also known as bromhidrosis, is the unpleasant odor produced by bacteria on the skin breaking down sweat and other bodily secretions. While sweat itself is odorless, the bacteria present on the skin, particularly in areas like the armpits, groin, and feet, metabolize components of sweat (like proteins and fats) into volatile organic compounds that produce the characteristic smell. Contributing factors can include poor hygiene, certain medical conditions (such as diabetes or kidney disease), metabolic disorders, diet (e.g., high intake of spicy foods or cruciferous vegetables), stress, hormonal changes (e.g., puberty, menopause), and certain medications or supplements. Body odor severity can range from mild and easily managed with basic hygiene practices to severe and socially distressing, potentially indicating an underlying health issue. In some cases, it may also be related to genetic factors affecting sweat gland function or composition of skin microbiome.
