A parent has Celiac’s and I know I’m a carrier of one of the associated variants related to it from an old DNA test. For unrelated reasons (positive for blood fecal occult of yearly health check), I had cameras in basically all of me and they found no indications. However, I had been mostly gluten free for months. Before the stomach camera, I did eat gluten for a few days, but nothing interesting showed up. I was told I could do some blood tests off insurance at a high price (probably not too crazy since this is Japan and not the US), but it wouldn’t actually be useful; currently there are no medications approved for use in relation to celiac’s in Japan and it would just make my life insurance more expensive and have other potential weird side effects.

My mom and her side have always had issues as well, being diagnosed as IBS among other things. I chose to get sterilized so at least the problem, whatever it is, ends here, heh.
