Heat and stomach cramps

During strenuous activity, the abdominal muscles can tighten as other muscles do. Heat exposure and sweating can reduce fluid stores, while dehydration may cause thirst, dry mouth, headache, dizziness, and darker urine. Stomach cramps with diarrhoea or vomiting may instead reflect gastroenteritis, food poisoning, or another digestive illness. Localised or persistent abdominal pain needs attention because the location, severity, and associated symptoms matter.

Note what happened before the pain: exercise, a hot environment, a meal, new medicine, or contact with someone unwell. A clinician may examine your abdomen and assess hydration.

Stop exertion and move to a cool place. Rest, loosen tight clothing, and take small sips of water if you are alert and able to keep fluids down. If fluid losses are substantial, oral rehydration therapy may be considered. Avoid heavy meals, alcohol, and strenuous activity until symptoms improve. Do not use pain medicine to mask severe or worsening abdominal pain without advice.

Get urgent help for severe or worsening pain, a rigid or swollen abdomen, fainting, confusion, blood in vomit or stool, repeated vomiting, inability to keep fluids down, or very little urine. Prompt review is also needed for fever with significant abdominal pain or pain that settles in one specific area.

Ask whether the timing fits heat cramps, dehydration, or a digestive illness; whether you need hydration assessment or tests; and what food, fluid, and activity choices are suitable while recovering. Ask which change in pain should prompt emergency care.
