Red flags & when to go in person for Fainting (Syncope) - Triage

Audience: adult

Fainting, or syncope, is a sudden, temporary loss of consciousness usually caused by a drop in blood flow to the brain. Many fainting episodes are harmless and can be managed with rest and hydration. However, some fainting events may signal serious health problems. Telemedicine can help assess symptoms, provide advice, and guide you on next steps. It is important to recognize red flags that require urgent in-person medical care. These include fainting with chest pain, shortness of breath, or severe headache, fainting after a head injury, or repeated fainting episodes. If you experience these signs, seek emergency care immediately. Telemedicine is useful for initial evaluation and follow-up but cannot replace emergency or detailed physical examinations needed for some causes of fainting. This guide helps you understand when telemedicine fits and when to seek in-person care for fainting episodes.
