Frequent bathroom visits with a headache may be due to dehydration, infection, or dietary issues. Increase fluid intake and consult a doctor if symptoms continue, worsen, or are associated with fever or weakness.

Diarrhoea with watery stools, vomiting, and a fever of 101degrees Fahrenheit can quickly lead to dehydration. Start oral rehydration immediately and consult a doctor as soon as possible, especially if symptoms persist, worsen, or weakness develops.
