Chronic Abdominal Gastrointestinal
Unlike acute stomach pain, chronic abdominal pains are often recurring and may be brought on for a number of reasons. Exercise can upset the stomach and cause vomiting, bloating, cramps and wind. If exercise brings on these symptoms, there are things you can do to reduce the likelihood of them happening. Much of it is related to the food you eat, and you may wish to consult a doctor for their advice if it is a recurrent and severe issue.
Diarrhoea during or after intense exercise (most frequently running) is often referred to as 'runners trots'.
Gastrointestinal (stomach and intestine) problems during exercise (especially high-intensity exercise) are frequent. These may include heartburn, belching, abdominal cramps, nausea, diarrhea, vomiting and an urge to defecate.
