Need help on body odor due to undigested food what can i do for this to get rid of odor ?

Undigested food: I'm curious as to what makes you think you are not digesting your food? Our bodies are incredibly good at squeezing essentially everything we can use out of food, and bacteria in our gut uses pretty much everything else. What body odor problem are you having? Eating certain foods (garlic, onion, etc) will cause body odor. Let me know more specifics!

GI evaluation: Time for a thorough GI evaluation, blood and urine testing and try avoiding antibiotic therapy unless mandatory as it can change intestinal bacteria that help us digest.
