Do you experience unpleasant symptoms after your Friday night pizza? If the answer is yes - you may have celiac disease or an intolerance to gluten.

Although both are a result of a negative reaction to gluten, there are distinct differences - particularly in their severity. While celiac disease is an autoimmune disorder which damages the lining of the small intestine [1], gluten intolerance refers to a difficulty in digesting foods which contain gluten but no damage is caused to the tissues of the small intestine [2].

The difference between celiac disease and gluten intolerance

Celiac disease is an immune reaction to gluten; a protein found in wheat, barley and rye. When gluten is consumed, it triggers a reaction in the immune system that damages the lining of the small intestine - over time, this can prevent the body's ability to absorb nutrients from food.

Common indicators of celiac disease include:

  • Diarrhea
  • Fatigue
  • Weight loss
  • Bloating and gas
  • Abdominal pain

Gluten intolerance is essentially an intolerance to gluten. This means, when a person who is gluten intolerant ingests gluten, they will experience short-term bloating and belly pain. In contrast to celiac disease - it’s uncommon for this to cause long-term harm to the body [3].

Common indicators of gluten intolerance include:

  • Stomach pain
  • Bloating
  • Wind and/or diarrhoea

These typically occur a few hours after consuming gluten.
