Want to know what is the real cause of my body odor and what can I do to stop it was told that digestive enzymes after meal would help with the odor.

See a doctor. I recommend seeing a doctor so that they can make a proper diagnosis and give you something to get rid of the condition or relieve symptoms. It is difficult to find the reason why because I do not have your medical records nor do I know your lifestyle, so it is best to see a doctor for this so they can find the underlying cause.
