All this odor is probably from bacteria - now from which bacteria...
If you have bad breath you can have a breath test for Helycobacter pylori (but this, if at all, is probably only one part of the problem).
You can try with low-sulphur diet:
If you have smelly sweat (armpits) you can try some antibiotic ointments (ask in pharmacy). Bacteria break down sweat and produce smelly products.
In long term I would consider a change in diet - avoid sugary foods, so try to cut down sweets (sucrose), dairy (lactose) fruits (fructose). Sugars are food for bacteria.
