question: Hi there, I am severely anemic and have been for a while now, I have stomach pains after eating and they last all day. I have had a colonoscopy, ultra sound, capsule endoscopy, endoscopy, and a ct scan. And my doctor cant seem to find out what is causing my anemia, I was taking iron pills but have now stopped because it is really hard on my stomach, i am now getting iron injections. Any ideas what could be causing this? I have low energy, iregular heart beats, low blood pressure, light headiness, i would appreciate your help very much, thankyou.
