Intense physical exercise decelerates gastric emptying, absorption and digestion, and leads to serious symptoms, including gastrointestinal bleeding. Gastrointestinal bleeding is mostly reported in runners. Gastroesophageal reflux is commonly observed in endurance athletes. The most common endoscopic finding in physical exercise related gastrointestinal bleeding is hemorrhagic gastritis. Gastrointestinal symptoms are widespread especially in marathon runners: the incidence of gastrointestinal system (GIS) varies between 8-35 %. Hemorrhagic gastritis is the most often reported exercise related endoscopic finding. Colon is the second most common affected location. Peptic ulcer and diarrhea are also among common GIS disorders in athletes. Proper nutritional support plays an important role in the treatment. Avoiding fatty foods, and a high protein diet are recommended prior to racing. In diarrhea, fluid replacement has the priority in treatment. To prevent upper gastrointestinal symptoms, antacids may be prescribed to be administered 30 min prior to racing. Pertaining knowledge in the area is presented.
