  • Title: [Gastrointestinal ischaemia during physical exertion as a cause of gastrointestinal symptoms].

    Abstract:
    Gastrointestinal (GI) symptoms are reported by up to 70% of endurance athletes. Although exercise leads to decreased gastrointestinal blood flow, GI-ischaemia is rarely reported as a cause. Mucosal ischaemia may result in nausea, abdominal cramps and bloody diarrhoea. After exercise, reperfusion damage and endotoxaemia may cause systemic symptoms as well. In three patients, two women aged 46 and 25 respectively and a man aged 40, with a heterogeneous presentation of exercise induced GI-symptoms, GI-ischaemia was demonstrated using gastric exercise tonometry. Gastric tonometry is mandatory for the diagnosis and follow-up. In the first patient, an isolated celiac artery stenosis was found; after incision of the left crus of the diaphragm, she was asymptomatic and the results of gastric tonometry improved. The other two patients had non-occlusive ischaemia associated with high exercise intensity. Reduction of the exercise intensity resulted in the complaints disappearing.
