WebMD provides health information written for a general audience. It covers conditions, symptoms, treatments, medications, and healthy living topics like diet and exercise. The symptom checker lets you enter what you're feeling and get a list of possible causes, though it's not a diagnosis. There are also slideshows, videos, and quizzes that make some topics easier to digest than a dry medical article.

The site is widely used by people who want to understand a condition before or after seeing a doctor. It's not a substitute for professional medical advice, and the symptom checker in particular should be treated as a starting point rather than an answer. The content is reviewed by medical professionals, and the site includes a medical reference section with more detailed information. For general health questions, it's one of the most visited sources online.
