Celiac Disease
An autoimmune disorder in which gluten ingestion damages the lining of the small intestine. Lifelong, measurable, and treatable only with strict dietary change.

Symptoms
Migraines, anemia, joint pain, infertility. The non-digestive presentations of celiac disease are often what delays a diagnosis by a decade.

Diagnosis
From the first suspicion to a confirmed result, here is what a careful, evidence-based path to diagnosis actually looks like.

A primer
Treating one as another can delay diagnosis by a decade. Understanding the difference is the foundation for everything that follows.
An autoimmune disorder in which gluten ingestion damages the lining of the small intestine. Lifelong, measurable, and treatable only with strict dietary change.
Real and reproducible symptoms without the autoimmune markers or intestinal damage seen in celiac disease.
A classical IgE-mediated allergic response to wheat proteins. Sometimes severe, often outgrown in childhood.
The body, listening
Roughly half of newly diagnosed adults present without prominent digestive symptoms. The systemic picture is broad, and easy to miss.
Bloating, abdominal pain, chronic diarrhoea or constipation, nausea after meals containing gluten.
Migraines, peripheral neuropathy, and the cognitive haze often described as 'brain fog'.
Dermatitis Herpetiformis — an intensely itchy, blistering rash linked specifically to gluten.
Iron-deficiency anaemia, low B12 and vitamin D, unexplained weight loss despite normal intake.
Failure to thrive, delayed puberty, dental enamel defects, irritability, and short stature.
A careful sequence
A reliable celiac diagnosis is a sequence, not a single test. Skipping a step — or going gluten-free before testing — can produce false negatives that take years to untangle.
Track symptoms, family history, and food patterns over weeks.
A clinician reviews extra-intestinal signs and family risk.
A blood panel measures tTG-IgA antibodies — while still eating gluten.
A small-bowel biopsy confirms damage to the intestinal villi.
A confirmed result, a referral, and a baseline for follow-up.
A strict, lifelong gluten-free diet, supported by a dietitian.

Reader letters
We strongly discourage it. Diagnosis requires that you be eating gluten when the tests are done, and a confirmed result changes how you are monitored for the rest of your life.
No. A wheat allergy is an IgE-mediated allergic reaction to wheat proteins. Celiac disease is an autoimmune condition triggered specifically by gluten and produces intestinal damage that an allergy does not.
Most people notice an improvement within weeks. Full intestinal healing can take six months to two years, and is monitored by follow-up serology and, sometimes, a repeat biopsy.
Only certified gluten-free oats. Standard oats are routinely cross-contaminated during growing and processing, and a small minority of people with celiac disease react to oat protein even when uncontaminated.
