My daughter is 26, in good health, has celiac disease and follows a strict gluten free diet. She was diagnosed at age 21 and her main symptom was constipation despite a healthy diet. She thinks she was accidentally exposed to gluten about three weeks ago. Since then she has been very ill. She has stomach pain, bloated, constipated has some degree of anorexia. She tried an enema yesterday with some results. Yesterday she has a bowel movement with a pink flaky substance. She does feel unwell for days after accidental gluten exposure but this seems prolonged. Thoughts?
