I'm writing this post because I have had a few conversations with people both online and offline lately where they suspect that they have coeliacs disease or are gluten intolerant or they test positive to the coeliac blood test and they state that they will trial going gluten free.
So my response is DON'T STOP EATING GLUTEN NOW!!!!!
Eat lots of gluten and have all of the coeliac tests first including the biopsy. The general consensus is that you need to eat at least four slices of wheat based bread (or equivalent) each day for 6 weeks prior to the biopsy. It's important to know properly because it's a serious autoimmune disease which can lead to other health problems including malabsorption of nutrients, osteoporosis, infertility, miscarriage and small bowel cancer. Also, if you are not eating enough gluten you might get a false positive for the blood test or the biopsy.
The other thing is if you simply decide that you are gluten intolerant without getting tested you could be doing some damage. Since most gluten intolerant people are not as strict about avoiding gluten as you need to be with coeliacs disease. Imagine spending a lifetime eating tiny bits of gluten and then find out you have caused other issues.
Also I'm trying to save others from the situation I was in where I went g/f for a few months didn't feel better then returned to eating gluten and felt worse than I ever had. I then spent a few months feeling really horrible, had horrible fatigue and was constantly sick. I wished someone warned me and then I would have just continued eating gluten.
