When my stomach growls from hunger if I don't eat within a few minutes I get nauseated and there is sharp pain. I also get very irritated. When I do eat it seems like it's only an hour or so when it starts again. I have tried different foods from proteins to starches to sugary things, unless I eat a full meal I can't seem to go for more than an hour without eating again. Then most times I have to go to the bathroom almost right away (loose stools). I have had my gallbladder removed. Any ideas??
