My daughter is 22 years old and has had intermittent symptoms most of her life. In fact, at age 4 she had an upper GI and colonoscopy because of diarrhea, pain, and some minimal bleeding. Before they scheduled the colonoscopy, they ruled out parasites and infectious causes. She also had a lot of blood work and stool samples done. They could never find anything and after awhile, her symptoms resolved. Then at around age 12 she started having symptoms of bloating, stomach pain and belching. At that time she had a CT scan, an upper endoscopy and an upper GI. They found a hiatal hernia (not severe) and large ovarian cysts. I guess I always thought that since she didn't have Crohn's, maybe she had IBS, which I guess is still a possibility. She has also been diagnosed with Chronic Fatigue Syndrome and has many allergies. She has also suffered from anemia but it is intermittent.
I guess we'll just have to wait for the biopsies. I have heard about some people having a difficult time being diagnosed with Crohn's. I'm just hoping that something isn't missed.
