<<Disclaimer: Verify this information before applying it to your situation.>> Just read a brief input from one of the members of this board that said that her husband suspected that his routine colonoscopy may have triggered his Celiac. I have wondered about this also, but never mentioned it to my Gastro. Dr. because I thought it just my imagination. But the timing is uncanny. I had no real symptoms until my routine colonoscopy for my 50th birthday. Not long after, I started to feel weakness, had bouts with excruciating upper stomach pain (exactly like I felt during the procedure) and cramps after eating heavy meals and finally being diagnosed with acute iron deficiency. That was four years ago and last year, I was finally diagnosed via blood test and biopsy as Celiac. I'm still down around 20 lbs, but leveled off (pretty skinny). Energy level is up and down like a roller-coaster. (I'm sure the stock market isn't helping) Trying as best I can to stay on strick diet. Has anyone else suspected that colonoscopy or surgery triggered Celiac? Bob
