What is gluten intolerance 

Gluten intolerance often appears after intense periods of stress, which has the effect of creating changes to the bacteria and environment of the gut.  It is understood that gluten intolerance is caused by an inability to break down and digest the gluten protein called gliadin.     

What is gluten sensitivity

Gluten sensitivity is a delayed immune response often occurring hours or days after eating gluten, making it difficult to associate with symptoms. It is unknown if gluten intolerance leads to gluten sensitivity, but the prolonged use of gluten can trigger further food intolerances. Gluten intolerance and gluten sensitivity have very similar symptoms, and their origins are not fully understood.

What is Coeliac disease 

Coeliac disease is an autoimmune disease where the body attacks its own tissue as a response to eating gluten.  This reaction causes damage to the gut lining preventing the absorption of nutrients from food.  Coeliac disease is not an allergy or food intolerance and can lead to further problems of osteoporosis and anaemia. 

 Top Five Symptoms of Coeliac Disease 

Abdominal pain; bloating, and stomach cramps 


Unexplained weight loss

Mouth ulcers 


Top Five Risk Factors for Coeliac Disease 

A skin condition called dermatitis herpetiformis 

Having a family member with Coeliac Disease

Type 1 diabetes 

Autoimmune thyroid disease 


How do I know if I have Coeliac disease  

It is essential to first rule out Coeliac disease through a blood test with your GP.  Before you do this, you will need to continue to eat gluten-containing foods.   Your body needs to be producing the autoantibody for the test to show a positive result for Coeliac disease.  

If you have been diagnosed with coeliac disease, you should strictly avoid all gluten-containing foods.   If you test negative for Coeliac disease, your GP will consider other conditions such as Irritable bowel syndrome (IBS) or Irritable bowel disease (IBD).  IBS is a common condition and shares similar symptoms to gluten intolerance and gluten sensitivity, and for some, the avoidance of gluten reduces IBS symptoms.
