Question: why does my stomach hurt after practice?
Answer: Strenuous exercise and dehydrated states would be the causes of gastrointestinal symptoms. Gut ischemia would be the main cause of nausea, vomiting, abdominal pain and (bloody) diarrhea [3]. Moreover, anaphylaxis is observed during or soon after exercise when preceded by the intake of a causal food allergen [4,5].
