Can Telemedicine Treat Stomach Flu (Gastroenteritis)?

Audience: adult

Stomach flu, also called gastroenteritis, is an infection that causes diarrhea, vomiting, stomach pain, and sometimes fever. It often results from viruses, bacteria, or parasites. Most people recover without special treatment by resting and drinking fluids to avoid dehydration. Telemedicine can help by letting you talk to a healthcare provider from home. They can assess your symptoms, suggest ways to manage them, and tell you when to seek in-person care. However, telemedicine cannot provide emergency treatment or perform physical exams and tests that might be needed in severe cases. If you notice danger signs like severe dehydration, bloody diarrhea, or high fever, you should get urgent medical attention. Preparing for a telemedicine visit includes noting your symptoms, recent exposures, and any medicines you take. After the visit, follow advice on hydration, diet, and symptom monitoring. This guide helps you understand what telemedicine can and cannot do for stomach flu and when to seek more care.
