It was a full medical check up with blood test, hpylori test, but i guess it was more of the symptoms of which i mentioned like loose bowel movement, undigested food in stool, gas from mouth, bad breath, Bo, smell of rotten food in my breath etc. it was a process but we are glad was fixed. Try what i do, it will not cost you more than $20, maybe it will help you my friend. Ask your doctor about it too, they should help you....thanks.
