Results: The most prevalent symptoms were abdominal pain (55%), dysphagia (45%), emesis (35%), chronic or episodic diarrhoea (33%), coughing while eating (33%), and anal incontinence (30%). Twenty-five per cent of the patients considered their GI problems to be the most disabling consequence of the disease, and 28% had GI problems that started before the diagnosis of MD.
