For the past month I get sick every time I eat. There is no chance I'm pregnant. I've been doing the Atkins diet and have lost almost 25 Lbs but recently started feeling very ill when I eat. At first I thought it was the flu but after a week went by I went to the Dr and he said it wouldn't last that long. I eat, I get nauseas, sometimes may throw up and sometimes get very bad stomach pain. I've tried limiting my food intake to certain items to rule out certain foods but seems there is not just 1 certain food that makes me sick.I'm otherwise very healthy and take very good care of myself, I'm just sick of feeling sick all the time! I went for an ultrasound today and everything looked "normal" what gives?
