I started to feel sick on Tuesday, and threw up. Ever since then I have had chills, loss of appetite, bloating after meals that lasts hours, loose stool, gas, and nausea. I thought it was a stomach bug, but it has lasted this entire week and will get better until I eat food. Today I felt fine until I ate a quarter of a sandwich and have been throwing up off and on. Was worried about possible gallbladder issues?
