Hello there, If you feel your body has a very different odour then first avoid these foodstuffs- onions, garlic, asparagus, cured meats , eggs. These get secreted in the sweat and saliva and cause a bad odour. Next are you perceiving your bad breath as body odour? Take a deep breath and blow into your hands while they are cupped. If you can smell a bad odour then its more likely it is halitosis. You need to visit an ENT doctor to isolate the cause of your bad breath. Please get your blood checked for CBC including TLC . Sometimes in autoimmune conditions the body attacks structures like your salivary glands and this results in your body being more odour producing. This test will help us figure out if that is the case with you. Hope this helps, Please get back to me with any further queries. i will be happy to help you.
