What should you know about celiac disease bloating?

Most people with coeliac disease notice digestive symptoms such as bloating, abdominal pain, diarrhoea or changes in bowel habit, although symptoms vary. Immune-related inflammation can interfere with digestion and absorption. Iron or vitamin B12 deficiency may contribute to fatigue or other symptoms. Bloating is not specific to coeliac disease, so its presence does not show that a person has the condition.

Book a medical appointment if bloating persists or appears with diarrhoea, fatigue, weight loss, recurrent abdominal pain or signs of deficiency. Ask about coeliac blood testing before removing gluten, because a gluten-free diet can affect the results. Keep a simple symptom and food record, but avoid using it as a substitute for testing. A Blood Test may be one part of the assessment.

Seek prompt care for bloating with blood in the stool, black stools, repeated vomiting, dehydration, unexplained weight loss or worsening weakness. Obtain urgent help for severe or sudden abdominal pain, fainting, a rigid swollen abdomen or difficulty breathing.

Ask which coeliac tests are suitable while you are eating gluten, whether anaemia or vitamin deficiency should be checked, and whether your bowel symptoms need another explanation. Mention family history, previous test results, dietary changes and symptom timing.
