Diarrhoea that is characteristic of coeliac disease is chronic, sometimes pale, of large volume, and abnormally foul in odor. Abdominal pain, cramping, bloating with abdominal distension (thought to be the result of fermentative production of bowel gas), and mouth ulcers[35] may be present.

Coeliac disease leads to an increased risk of both adenocarcinoma and lymphoma of the small bowel

Long-standing and untreated disease may lead to other complications, such as ulcerative jejunitis (ulcer formation of the small bowel) and stricturing (narrowing as a result of scarring with obstruction of the bowel).
