For reliable health answers, match the source to the need: use a government health service, medical school, hospital, or professional organization for general information; use an official local triage service for help deciding where to seek care; and contact a qualified healthcare professional for advice about your own symptoms, medicines, test results, or treatment. Online information and automated tools cannot assess your personal situation the way a clinician can.

Choose the right kind of help

Your need Best starting point What it can and cannot do
Understand a condition, treatment, or health term A government health service, medical school, hospital, or relevant professional organization Provides background information; does not make a personal assessment or replace advice from your clinician.
Work out what to do about a symptom An official symptom-triage service in your area, if available Can direct you to a suitable next step. Triage is not a diagnosis.
Get advice that accounts for your medical history or circumstances Your healthcare professional, such as your own practice or a licensed telehealth provider A clinician can assess your situation and decide whether remote advice is enough or you need an examination or test.
Possible emergency Your local emergency service or emergency number Do not wait for a website, chatbot, or online consultation to respond.

Where to find trustworthy general health information

MedlinePlus provides patient-friendly health information and guidance on evaluating online sources. It names the CDC and organizations including the American Heart Association, American Diabetes Association, American Academy of Family Physicians, and American Academy of Pediatrics as examples. Choose an organization that matches your topic and check the date and scope of the specific page.

Before relying on a health page, check who is responsible for it, who wrote or reviewed it, whether it cites evidence, when it was last reviewed, what its purpose is, and how it handles personal information. MedlinePlus advises: “Do not rely on just one website.” Compare important claims with another dependable source, especially when they concern risks or treatment. Its article “Online health information — what can you trust?” was reviewed September 15, 2024; individual pages can have different review dates.

Even accurate general information may not apply to your medical history, medicines, or circumstances. MedlinePlus advises contacting your healthcare provider with questions about your health, treatment, or information you find online.

For symptom routing in England: NHS 111

NHS 111 online is an official symptom-triage service for England. It asks questions about the main symptom and helps identify what kind of help to seek next. The NHS says it covers about 120 topics; the page does not state a publication year for that figure. The service uses the same system as the 111 phone service, but it does not diagnose: “You will not get a diagnosis, but you will find out what help you need.”

Depending on the situation, NHS 111 may direct you to emergency services, an urgent treatment centre, an out-of-hours GP, a nurse callback, specialist support, your own GP, a pharmacist, or self-care. Routing and availability can vary locally, so follow the service’s current instructions.

If the problem is an emergency, follow local emergency instructions instead of waiting for an online response.

For personal advice: contact a clinician

A virtual appointment or secure message with your own practice is more appropriate than a general information page when you need advice based on your symptoms, medical history, or treatment. Depending on the provider and circumstances, telehealth can support general care, prescription questions, dermatology, eye exams, nutrition or mental health counseling, and some urgent concerns. The available services, coverage, and rules depend on your location and provider.

Remote care has limits: the clinician may not have your complete history, and some concerns require an in-person examination or laboratory test. A remote consultation is not automatically a substitute for a visit in person.

NHS App online consultations

Patients at participating GP surgeries may be able to send questions or symptom information through an online consultation in the NHS App and receive advice. A practice must enable the service, and the supplier can depend on the practice or integrated care board. It is not for emergencies: the NHS directs urgent cases to NHS 111, A&E, or 999, as appropriate.

This arrangement applies to the service described in that notice; do not assume it applies to unrelated commercial websites or chatbot services.
