What is health literacy?
Health literacy involves being able to find, understand and use health information to make informed decisions and communicate effectively with healthcare professionals. It is not simply knowing medical vocabulary.
Health information can be complicated, and credible sources can sometimes disagree because evidence or recommendations change. Good health literacy includes recognizing uncertainty and checking important information.
Evaluating health information
Consider who produced the information, what evidence supports it, when it was updated and whether the source clearly distinguishes facts from opinions. Be cautious with dramatic claims, guaranteed cures and advice that encourages people to replace professional care with an online product.
For medical decisions, information from qualified healthcare organizations and professionals is generally more useful than unsupported social media claims.
Understanding medical results
Ask questions when a test result, diagnosis, medicine or instruction is unclear. Understanding what a result means, why a test was ordered and what follow-up is recommended can help people participate more effectively in their healthcare.
Do not assume that a single number or symptom provides enough information to diagnose a condition.
Using digital health tools responsibly
Health applications and AI tools can help organize information and support learning, but they have limitations. They should not be treated as replacements for professional diagnosis, emergency care or individualized medical advice.
Keep useful health information organized
NizHealth helps people keep personal health information, measurements, symptoms, medicines, documents, reminders and other records organized in one place. Organized records can make it easier to review changes over time and prepare for conversations with qualified healthcare professionals.

Asking better health questions
Health literacy also means knowing when you need more information. Useful questions can include what a test result means, what the possible explanations are, what treatment options exist, what side effects to watch for, and when follow-up is needed.
Online health information should be checked carefully. Prefer reputable medical organizations, government health agencies, hospitals, and established medical reference resources. Be cautious with content that promises guaranteed cures, relies heavily on testimonials, or presents complex medical issues without uncertainty or evidence.
