<<Disclaimer: Verify this information before applying it to your situation.>> Have any diagnosed celiac's out there ever been diagnosed with diverticulitis as well, or prior to, their celiac diagnosis? My grandfather was diagnosed years ago with diverticulitis and I am wondering if he has actually been misdiagnosed all these years. He still complains about everything he eats and now my grandmother has been complaining that she can't cook anything cause he says it bothers him, no matter what it is. He also has sugar problems, blacks out if he has too much sugar. So far no one else in our family has been diagnosed but I am thinking there might be a connection between his diverticulitis, his daughter's endometriosis problems and my celiac. His other daughter, my mother, has been blood tested but came up negative, so far. I don't think my grandfather's dr is very up to speed on things, so I figured I would see if anyone had any info out there for me. I had been reading more about diverticulitis and saw that they made reference to possibly having IBS, instead of or as well as diverticulitis, which made me think. We all know how many dr's diagnose IBS and don't look for celiac! Thanks for any input! Renee Naperville, IL
