I've struggled with "IBS" for 20 years now (since I was 17). However, I've always thought it HAD to be more. In 2019 I had some blood test ran ttg and iga (?) And they were normal range. Now, I also had some genetic tests ran that show I carry a gene making me high risk for celiac. I am miserable almost every day and spend a good 50% of my time in the bathroom...
