What to do if you have symptoms?
Common symptoms of coeliac disease are bloating, nausea, tiredness, an unexplained change in weigh- either up or down, constant diarrhoea, mouth ulcers, body rashes and constipation are the most common flags. If you have any of these then the first person to see is your GP.
There are local support groups and talking helps.
If they think its necessary then they will give you a simple blood test, however the best and most conclusive test is a laparoscopy, in simple terms a camera and a biopsy. It is possible to see how much damage has been done to the small intestine.
It is very important to continue eating a gluten diet to make a diagnosis, if you switch to a gluten free diet before diagnosis it would work correctly.
If the tests come back positive, and you have celiac disease now you must switch to a gluten free diet and remain on it for the rest of your life.
There will be times when you will be tempted, and this is when it is hard, and you must remember the damage even the slightest bit of gluten will do.
There are places for support, the Coeliac UK is the largest
