If you think you may have Coeliac Disease it is important to carry on eating foods that contain gluten - in other words eat normally - but visit your doctor and arrange to be tested. This begins with a very simple blood test, nothing to be alarmed about. You will only get a true test result if you have been eating gluten (some people suggest for at least six weeks) prior to being tested. If you have excluded gluten from your diet because it is making you feel ill - then the chances are that your test results will turn out to be negative even if you do have Coeliac Disease. If your test is negative then you may well have Gluten Intolerance or Gluten Allergy so it is worth discussing this possibility with your doctor to receive any help and advice that is available.
Coeliac Disease symptoms do vary and although many have the symptoms that are on all of the main NHS site there are many more that do not - so it is also important to be tested if your symptoms are different but you sense that they are improved if you do not eat gluten.
If you have Coeliac Disease or you have Gluten Intolerance or you may be Allergic to Gluten then here are some symptoms that you may well have that are not always easy to find on the Web: headaches, indigestion, reflux, tiredness, poor sleep patterns, heartburn, stomach cramps or pains, acid stomach, bruising either on the skin or in the mouth, ulcers, mouth ulcers, blisters on the tongue/cheek/soft pallet/inside of lips, blood blisters in the mouth, tinnitus, thyroid problems, vitamin and mineral deficiencies, dry patches on the skin, weight gain or weight loss, hair loss, nerve aches and pains, joint pains, muscle aches, bone aches, tingling or numbness in hands and/or feet, thyroid problems, periods of melancholy, difficulty conceiving, dry eyes, dry mouth, itchy eyes, skin rashes, swollen ankles, occasional swollen legs, neuralgia, sciatica, memory stalls, sinusitis, marks appearing on teeth similar to fluoridation markings, nausea, constipation and/or diarrhoea, overwhelming bouts of utter exhaustion, flashes of tiredness, vomiting ..
The one thing that is imperative is to refrain from eating any gluten in the diet as people who cannot process gluten (in very rare cases) may go on to develop Refractory Disease, which in simple terms means that the villi in the small intestines have been so constantly damaged that they are no longer able to repair themselves this is called persisting villous atrophy. This can happen if a person has an undiagnosed condition over many years or if a person refuses to stick to a gluten free diet. Occasionally this condition is treated with steroids to reduce the painful inflammation of the gut. It is important to reduce the risk of contracting RFD by sticking to a gluten free diet, as it may lead to further serious major health conditions.
