When Is GP Consultation Recommended for Gastroenteritis?

Gastroenteritis irritates the stomach and bowel, commonly causing diarrhoea, vomiting, cramps, nausea and sometimes fever. Vomiting and loose stools remove water and salts from the body, so dehydration is the main concern. A GP can assess your hydration, review possible infectious exposure and medicines, and decide whether testing or treatment is needed. Children, older adults, pregnant people and those with long-term illness may need advice sooner.

Sip water or an oral rehydration solution often, taking small amounts if nausea is strong. Rest and eat plain foods when appetite returns. Wash hands with soap and water, clean shared bathroom surfaces, and avoid preparing food for others while vomiting or having diarrhoea. Keep a note of urine, fluid intake, fever, stool appearance and the number of vomiting episodes so you can describe the illness clearly.

Get urgent medical help for fainting, confusion, severe weakness, very little urine, severe abdominal pain, bloody vomit or stool, breathing difficulty, or an inability to keep fluids down. Seek advice promptly if symptoms are worsening or you are concerned about a child, older adult or person with a weakened immune system. Do not wait for routine care when dehydration signs are marked.

Ask which rehydration drink is suitable, whether your medicines should be continued, how to reduce spread at home, and what recovery changes are expected. Ask when you can return to work, school or food preparation, and what symptom would require another assessment.
