Greetings. 1. Do you see any infection or skin colour / texture changes in the under arms - concurrent bacterial colonisation / infection can worsen body odour 2. Drink lots and lots of water - at least 3 litres per day 3. Wash inner wear / shirts / socks every day - reuse without washing causes further odour and infections 4. Try BPO based body washes or Triclosan based soaps - see a qualified dermatologist near you for further queries.
