Enter your symptoms into our Symptom Checker to see a list of matching conditions, plus advice on when to see your doctor.
How to get started
Begin by entering or selecting the symptoms that best describe your current condition.
Symptoms can be entered in your own words or chosen from the list of matching suggestions; select the most appropriate.
If no suggestions appear, double-check your spelling or use different words to describe your symptoms.
Submitting a symptom leads to a conversation with our medical AI assistant, AskPatient.
Answer the follow-up questions to be given a list of potential conditions, which can be accessed by tapping or clicking on them to get information.
Best practices
Use medical language as much as possible when entering symptoms. For example, "abdominal pain" is better than "belly hurts".
Start with entering the area of the body affected, then the symptom. For example, "abdominal pain" instead of "pain in abdomen".
Use text, not numbers. For example, enter "high blood pressure" instead of "BP 150/90".
Enter only abnormal test results, for example "low iron". Do not enter tests that you have been told are normal.
If you have recently travelled abroad, you may be affected by a disease more common in that country. In this case, select the country where you were travelling.
