After visiting my daughter in NY I contacted a severe case of vomiting and diaharrea. While I am at home now in PA and feeling much better after following the brat diet I continue to have loose stools that are yellow....last episode at my daughter s was exactly one week ago. Any significance here? Always have had a sensitive digestive system, am 75 yrs. old female taking numerous meds...blood pressure, fluid, reflux, eye vitamins, choles. med, etc.
