Medical help sites are online services that provide health information, practical guidance and routes to further support. They may cover symptoms, common conditions, medicines, prevention, mental wellbeing and caring for someone who is ill. Content can include articles, question-and-answer resources, checklists and explanations of medical terms, written for patients and carers. Some sites also help users find or access care, for example through directories of clinicians and services, appointment booking, online consultations or tools for preparing questions for a healthcare professional. The services available vary, and information may be general rather than tailored to an individual's circumstances. These sites do not necessarily diagnose conditions or provide emergency care; users with urgent symptoms should contact an appropriate medical service.
