What causes a change in body odour, and how can I reduce it?
Body odour often comes from skin bacteria breaking down sweat and secretions. Heat, activity, clothes, hormones, foods and medicines can influence it. A different smell does not automatically mean poor hygiene. Sudden or persistent changes deserve assessment.

Reduce odour without irritation
Wash and dry sweaty areas, change clothes and socks, and choose fabrics suited to heat and activity. Deodorants and antiperspirants have different purposes; a pharmacist can suggest options when ordinary products are insufficient.
Avoid excessive cleansing
Harsh scrubbing and fragrances on inflamed skin can worsen irritation. Antibiotics or strong home mixtures are not justified by smell alone. Rash, pain or discharge may indicate a problem needing different treatment.
What to discuss at review
Describe timing, medicines, excessive or night sweating and weight changes. Addressing a local factor may suffice, while selected cases need wider assessment. Diabetes or kidney disease cannot be diagnosed from body odour alone.
