Struggling with bloating, stomach pain or fatigue after eating bread or pasta? Gluten intolerance is common and often missed. This hub explains symptoms, causes, what to eat, and how to confirm if gluten is your trigger.
What is gluten intolerance?
Gluten intolerance (also called non-coeliac gluten sensitivity) is when your body reacts negatively to gluten — the protein in wheat, barley and rye. Unlike coeliac disease, it doesn’t damage the small intestine, but it can still cause digestive pain, bloating, headaches, brain fog and fatigue. Gluten hides in sauces, cereals and many processed foods, which is why symptoms are often labelled “IBS.”
Gluten intolerance vs coeliac disease (quick comparison)
- Gluten intolerance: sensitivity causing digestive and whole-body symptoms.
- Coeliac disease: autoimmune reaction that damages the gut lining (requires medical diagnosis).
- Wheat allergy: IgE immune response to wheat specifically.
If symptoms are severe or persistent, speak to your GP about coeliac screening.
Common symptoms to watch for
Bloating after meals • stomach cramps • diarrhoea or constipation • gas • headaches/brain fog • chronic fatigue • joint or muscle aches • skin flare-ups (eczema/dermatitis).

How to confirm if gluten is your trigger
A strict elimination diet for 6–8 weeks can help, but symptoms are often delayed and hard to interpret. A faster route is a comprehensive intolerance test that screens gluten alongside other common triggers (dairy, egg, yeast) so you don’t miss the real culprit.

Managing gluten intolerance (quick start)
- Eliminate gluten strictly for 6–8 weeks; track symptoms daily.
- Use naturally gluten-free staples (rice, quinoa, buckwheat); watch “hidden gluten” in sauces and seasonings.
- Reintroduce cautiously to confirm sensitivity.
- Support gut health (sleep, fibre, pre/probiotics) and avoid ultra-processed “GF junk.”
