The websites for Mayo Clinic, Medline Plus and Cleveland Clinic are three informative, trustworthy sites with expert information on health and medical issues. These sites contain information on many topics. Information geared toward specific health issues is available on Cancer.org, Diabetes.org and the Centers for Disease Control and Prevention website.
There are many websites available for medical and health-related questions, but not all are equal. Sorting the good from the not-so-good is difficult, given the many choices available. Johns Hopkins Medicine and other highly reputable sites recommend basing evaluations of any medical websites on the accuracy of the information, the authority of the presenter, any biases the site may have, how current the information is, and how comprehensible it is for the reader.
