<<Disclaimer: Verify this information before applying it to your situation.>> I am a diagnosed celiac since age 12; am now almost 28. My sister was diagnosed with celiac last summer at age 19. Currently, my 24 year old brother (who has never been tested for celiac) has been experiencing pain in his bowels; it's usually worse after eating. He saw a doctor and the dr said he felt a mass in or near the colon. He had a CAT scan done, but all that did was let them know it's not a solid mass; however, they won't say it's a tumor and won't rule it out. He has an appt with a GI dr next Tuesday. I am wondering if anyone who has been diagnosed with celiac has ever experienced something similar prior to diagnosis. Due to this experience and to family history, my brother will probably request celiac testing now. Prior to diagnosis, my sister and I had symptoms, but not anything as dramatic as this. My brother's wife has also noticed that my brother seems to be either constipated or have diarrhea, which I know can be an indication of celiac. If anyone has had a similar experience, or knows of someone who has, please email me privately. I would appreciate any information I can pass along to my brother and his wife. Thanks very much!
