Can untreated coeliac disease cause bloating, weight loss, or anaemia, and what is the diagnostic pathway?

Yes, undiagnosed coeliac disease can deplete iron, thin the bones, and cause persistent bloating. Diagnosis begins with coeliac-antibody blood tests. A positive result is followed by a brief endoscopy to sample the small-bowel lining. It is important to continue eating gluten until after the biopsy to ensure accurate results. A baseline bone-density scan often follows. Our specialist dietitian then guides you through a gluten-free diet that usually brings relief within weeks. We recommend repeating antibodies at six to twelve months to confirm healing. Many patients log meals and symptoms in a free app, which is remarkably helpful for fine-tuning.
