DEAR SAVVY SENIOR: What are the best websites for finding reliable health information on the Internet? I usually do a Google search on a symptom, drug or health condition when I want to research something, but with so much information out there, I’m not sure what I can trust. — Untrusting Senior

DEAR UNTRUSTING: You’re wise not to believe everything you read, especially when it comes to health and medical information on the World Wide Web. To help you sort through the online clutter and locate trustworthy medical information, here are a few tips to follow, along with some top-rated sites you can always turn to with confidence.

As a general rule, health and medical information websites sponsored by the U.S. government, not-for-profit health or medical organizations, and university medical centers are the most reliable resources on the Internet. Sites supported by for-profit companies, such as drug or insurance companies who may be trying to sell you their products, are usually not your best option.

To find out who’s sponsoring a site and where the information came from, click on the “About Us” tab on the site’s home page. Also look for the red and blue “HONcode” seal at the bottom of each page, which means the site has credible information and is certified by the Health on the Net Foundation. However, government-sponsored health sites don’t have the seal.

Also be aware that good health and medical information changes all the time, so check the date that information was published to make sure it’s current. And, if you’re doing research online before seeing a doctor, print your findings out on paper, including the site you got your information from, so you can review it together.

TOP HEALTH SITES

While there are dozens of great websites for health and medical information, here are two of the best all-purpose sites that are easy to use.

• Medlineplus.gov: Sponsored by the National Institutes of Health and managed by the U.S. National Library of Medicine, MedlinePlus provides information on more than 900 diseases and conditions in their “Health Topics” section, and links to other trusted resources. It also provides a directory of hospitals, clinics and health care providers, a medical encyclopedia and medical dictionary, tutorials on common conditions, tests, and treatments, extensive information on prescription drugs, supplements and herbs, and links to thousands of clinical trials. It even offers a senior specific health site (nihseniorhealth.gov) that makes age-related health information easier to get.

• MayoClinic.com: Owned by the Mayo Foundation for Medical Education and Research, this site is produced by more than 3,300 physicians, scientists and researchers from Mayo Clinic, and provides in-depth, easy-to-understand information on hundreds of diseases and conditions, drugs and supplements, tests and procedures. It also offers a nifty “Symptom Checker” tool and “First-Aid Guide” for fast answers to all types of health conditions, along with medical blogs, expert answers, videos and links to additional resources.

There are also dozens of other sites dedicated to specific diseases and conditions. Here are some top-rated sites listed by the Medical Library Association.
