About 10-20% of adults and adolescents are estimated to have symptoms related to functional bowel disorders, resulting in high healthcare costs.1 We report two cases of chronic diarrhoea and substantial weight loss in which extensive investigations had been performed previously. However, final diagnosis was only established after precise evaluation of eating habits, which showed habitual ingestion of sorbitol, a widely used sweetener in food products which has laxative properties.
A 21 year old woman had experienced diarrhoea and diffuse abdominal pain for eight months. She had four to 12 bowel movements with watery stools daily. She was initially suspected to have infectious colitis. However, as clinical investigation suggested no clear diagnosis and diarrhoea persisted, she was transferred to our department for further evaluation. At that time she had lost 11 kg and weighed 40.8 kg (body mass index 16.6). Laboratory analysis showed hypoalbuminaemia (albumin 30.7, normal range 33-50 g/l; total protein 64.3, 66-87 g/l). Further laboratory investigations (including antigastrin antibodies, antigliadin antibodies, endomysial antibodies, stool pancreatic elastase, and stool cultures) were normal.
