My daughter has it in both her colon & small intestine, and in her esophagus. When first diagnosed there was barely any un-diseased areas. She has had considerable healing and not her worst spots are bottom of esophagus, her terminal ileum and the top part of her colon ( the part that runs from right to left at the top of her abdomen). You can see the drugs she is on based on my signature below, but something not added in there is suppository enemas which are helping deal with the most troublesome part, the terminal illieum. We also doubt Humira is working. Just had the antibodies test to find out.
