My grandmother is 81 yrs old. She has almost daily nausea, vomiting, frequent diarrhea, gas. She had 13 in of her colon removed about 20 years ago and not a lot of problems since. Until about 2 years ago when my uncle, her son, passed away. She drinks ensure a lot, has not so great eating habits, smokes mail order cigarettes, and takes at least 7-10 medications. She attempts to eat food, then vomits it up almost half of the time.
