5. Actual results
- Results
Abstract: coeliac disease is a permanent immune-mediated response to gluten in wheat, barley and rye; tissue transglutaminase antibodies are very helpful for initial screening; intestinal biopsy is required in most patients to confirm diagnosis (non-biopsy strategy in selected children); treatment requires strict adherence to a gluten-free diet and lifelong medical follow-up; non-responsive disease needs work-up especially for unintentional gluten contamination.
- Absolute risks
not applicable
- Authors' conclusion
Strict gluten-free diet and lifelong follow-up are the current treatment.

15. Linked fact checks
- 'There is no such thing as gluten sensitivity'; the real problem is only that white flour turns into a glue-like substance. – Studies contradicting or limiting the claim
- Gluten is present in all grains, including oats, rice and maize, so 'gluten-free' bread or flour is a meaningless concept. – Studies contradicting or limiting the claim
- In a joint live stream on Elawady's channel, a speaker (Elawady or his guest Dr. Tamer El-Baz; speaker turns cannot be identified) describes a coeliac patient on the system who reintroduced gluten-containing toast, and advises pausing it when symptoms appear and reintroducing it later. – Studies contradicting or limiting the claim
- White flour coats the absorptive villi of the small intestine like glue and thereby causes malabsorption, which leads to irritable bowel syndrome, iron-deficiency anaemia, vitamin D deficiency, weak bones and teeth, fatty liver and hair loss. – Studies contradicting or limiting the claim
