Body odour is also known as Bromhidrosis. This occurs more commonly when an individual hits the pubertal age group and is caused by an increase in the secretions by of the eccrine (sweat) glands and apocrine glands. Bacteria present to degrade the secretions by the apocrine gland and excessive sweat leads to softening of the keratin and this too can be broken down by bacteria, leading the malodourous smell. This is also more commonly observed in males.
Excessive consumption of certain foods may also lead to body odour. Foods such as garlic, onions and certain spices and even certain medications, can be secreted in the sweat and lead to body odour.
Infections like erythrasma, which is due to the corynebacteria, is not an uncommon cause of body odour.
Underlying medical problems like obesity, diabetes and certain metabolic disorders can also be associated with bromhidrosis.
Personal hygiene is of utmost importance in treating bromhidrosis. Cleansing with antibacterial cleansers and changing out of sweaty clothes and keeping the body dry can help to decrease the bacterial load. Use of antiperspirants may be of benefit too.
If the body odour persists, you can see your doctor for a proper assessment and treatment.
