I lost my appetite months ago from food. I eat and have a normal weight. Last Saturday, I ate the night before. But, I was very sick and kept running to the bathroom. Before everything was fine. I had abnormal bowel movements but one had a little blood in my stool. I keep feeling dizzy, lost of appetite, sour and upset stomach. I even threw up once. Now, I normally get sick before my period. My cycle haven t started. I need help what is causing me to be sick? Tammy 31
