Why do I have these digestive problems? Any inout is great. Thank you

For the past two months I have had constipation and the only way I go is by using milk of magnesia. I have cramping, bloating, gurgling, pain and this gets worse after I eat. Some tests revealed anemia (internal bleeding may be suspected), and inflamed stomach. I don't feel like the doctors are helping. What do you think?

Have you had colonoscopy yet?  

Instead of MOM I used to use magnesium tablets and glycerin suppositories to promote bowel movements.  What doctors recommend now and what works for me is MiraLax.  I know I sound like a commercial, but the stuff works much better.  Just mix it with juice or other beverage in the evening and take it every night if necessary.  Anemia and inflamed stomach will have to be investigated also, and I have no tips for that, except that if periods are heavy, anemia can come from that, and hopefully not a bleed of the GI tract.  Don't let the docs ignore your needs.
