A 35-year-old man with known human immunodeficiency virus experienced chronic diarrhoea for 18 months. He presented to multiple hospitals with profuse secretory diarrhoea and life-threatening electrolyte disturbances. Infectious and non-infectious aetiologies were considered, with focussed history and investigations ultimately leading to a diagnosis of VIPoma. Initiation of somatostatin analogue therapy followed by surgical resection led to complete resolution of symptoms and markedly improved quality of life.
