Yes. I don't have health insurance and I have a hard time getting involved with the Western medicine runaround except in the event of an life-threatening emergency. I figured I'd start with the most basic step by simply eliminating what I think is causing the issues. It certainly won't hurt me, and if the results are obvious then gluten-free is the solution. If nothing changes, then it's on to Plan B, whatever that may be.
This has been my position exactly since I was diagnosed over 3 years ago. If a person does the gluten-free diet correctly only a couple of things will happen and none will be bad. One it will work, two it will not (and then it is on to your plan B without money spent on testing ) or three it will help to the extent that if something else is wrong it may allow this to become more apparent. The worst thing someone can do is to go about the diet in a less than 100% fashion (lack of knowledge or willpower) and then it will can make diagnosing anything almost impossible. Take it one step at a time. If gluten is only one of multiple issues then control that portion and move on the the next step. If it appears after being on the diet that it "is" the culprit then decide whether or not to go back to eating it and trying to get a diagnosis. Like I have said before then you know you are traveling in the right direction. This way "you" will control the process without putting it into the hands of the health care profession whose track record on diagnosing this condition (about 3%) leaves something to be desired.
