My daughter has celiac and it caused her multiple, terrible GI problems when she was younger. She'd also get really moody and irritable. Lots of screaming and crying and pain. Poor girl
Now that she's been GF for years she's so much better.
Because she has celiac I've been primarily GF for quite awhile now. Because it's a genetic disease it comes from either me or her father. He developed an autoimmune arthritis two years ago and has had GI issues his whole life, so I told him he should get tested for celiac. I said I'd do the bloodwork too, but in order to do that I had to start eating gluten again. Reintroducing it to my diet, I had immediate brain fog, fatigue, and ADD symptoms I haven't had in awhile. I never made the connection before, back when I was diagnosed with Adult ADD, that those symptoms had gradually disappeared in the last several months and that's when I rarely ate gluten anymore. Feeling so dumb and tired definitely triggered some depression as well.
Long story short, I'm done with gluten. I haven't gotten the bloodwork back, but I don't really care what the result is. I know what makes me feel better, so that's what I'm going to do.
