For the past few months I have noticed I keep getting perhaps a stomach bug where I get really bad diarrhea which usually only lasts about a day , but last week I randomly began to vomit bile and also had diarrhea. I started to get a really sore stomach which has lasted a whole week and I keep getting diarrhea on and off . The hospital mentioned getting bloods done do check for problems to do with my stomach but I previously already had tests done which all came back normal , I am just worried as I keep getting ill in terms to do with my stomach I also think I have lost a little weight in my face since being sick but I am not sure if that is because I am dehydrated. Is there any guidence someone can give me please on what to do next ?
