No, I didn't get that done. My doctor said something like "if they are really bad, I'll tell you to be strict with your diet. If the results are not that bad, I'll tell you to be really strict with your diet".
So it made no sense to get it done :P
Well, I tried drinking LOTS of water so I was in the bathroom often.. I still felt dry. Water is absorbed on the intestine like everything.. so if you have that damaged due to celiac's, it may generate the problem, I think. The only thing I know for sure is that I wasn't absorbing nutrients properly.
