Understanding gastroenteritis
Gastroenteritis may be caused by viruses, bacteria or contaminated food and water. Symptoms vary from mild discomfort to significant dehydration.
Most uncomplicated cases improve with hydration and supportive treatment, but medical review may be necessary when symptoms are severe or persistent.
Assessment and treatment
The doctor will assess your hydration, temperature, abdominal symptoms and medical history.
Treatment may include hydration advice, symptom-relieving medication, dietary recommendations or further investigation.
Preventing dehydration
Frequent small amounts of oral rehydration solution may be easier to tolerate than large drinks.
Patients who cannot retain fluids or who show signs of significant dehydration may require additional medical care.
