Don't greatly reduce the amount of wheat, rye and barley in your diet until after placing yourself under a doctor.

The people at the web site mentioned are really nice, they will inform you of what tests to get the doctor to run.

If you change your diet in advance of the tests they will not show up correct, ever, no matter how long you switch from diet to diet in the future for a 'challenge', those don't work with gluten.

(My old doctor didn't send me for the right tests therefore I have to see to my own diets without medical support)

If you hope to get foods prescribed at low cost or can claim back the cost, you need to give the doctor the chance to have obtained the right results at the right time.

Ideally the doctor will bear in mind your history and symptoms - though in my country that is usually not done (for almost any complaint).

Everything the people here are saying is good bearing that in mind.

Some people at the web site mentioned have gone the route without the doctor, and a few have obviously needed the change but the tests confused the doctor.

It's just that, once changed there's no going back for tests as they won't work except before the first time (something to do with how the villi grow).

Happy eating!
