How to find trustworthy health information online

The Internet is packed with trustworthy medical information you can use โ€” if you know what to look for. Here are 4 signs you can trust the health advice youโ€™re reading online.

When youโ€™re worried about a health symptom or want to learn more about a condition, whereโ€™s the first place you turn? If youโ€™re like most Americans, you probably head to your phone or computer and do a web search. And youโ€™re sure to get plenty of results. But not everything that turns up will be trustworthy health information or advice you can count on. 

โ€œHealth disinformation is rampant on the Internet,โ€ warns Catherine Johnson, MD. Dr. Johnson is founder and medical director of Precision Medical Care. โ€œSo in general: Trust but verify.โ€ How?

Step 1: Always check with your doctor before taking any medical advice. Here are 4 more ways to know if you can trust what youโ€™re reading online.

1. Look at what comes after the dot.

โ€œWhen looking online for medical advice, be sure the source is credible,โ€ says Mark Ambler, MD. Dr. Ambler is the associate chief of family medicine at Austin Regional Clinic in Texas. A quick tipoff? The websiteโ€™s URL. Reliable sites include government agencies, which end in .gov. Also on the list: 

  • National health organizations. 
  • Patient advocacy organizations. 
  • Medical centers. 

Their URLs typically end with .org. Good government and health organization resources include:

Thatโ€™s not to say that sites ending in .com canโ€™t be trusted. But be critical. If youโ€™re reading an article, it should quote experts and link to related research. Some articles are reviewed by medical professionals. Others are written by them. Both are a great sign.

For instance, the digital health management app Wellframe has a private health library. Itโ€™s stocked with articles, videos, and other health resources, all reviewed and approved by clinicians. All information in the library is fact-checked. And it often cites scientific studies and articles.

2. Study the studies.

Have you come across research you want to learn more about? Take a look at the quality of the research. Some questions to think about:

  • Was the study done with humans? Some research is done on animals. Itโ€™s helpful for scientists. But it doesnโ€™t always mean the results are true for you.
  • How many people were in the study? Fewer than 100 is thought of as a small study. You should take these results with a grain of salt.
  • Was the study peer-reviewed and published in a reputable journal? That means that experts have given the study their stamp of approval. This isnโ€™t always easy to figure out, especially if youโ€™re not used to reading science journals. But you can usually find out on the journalโ€™s website.

If you donโ€™t quite get what youโ€™re reading, donโ€™t worry. โ€œMany people have trouble understanding what can often be very academic and jargon-filled writing,โ€ says Caitlin Donovan. Donovan is the senior public relations director at the National Patient Advocate Foundation. โ€œReading the summary and the conclusions can give the reader a good overview.โ€ Those sections are often easier to follow.

To dig deeper, Donovan suggests searching for the study online. Did reputable news outlets write about it? Did the researchersโ€™ university or organization publish a news release or blog post that explains the studyโ€™s findings in simple terms? Both point to more valid research. 

3. Check the date.

โ€œThe more current a study is, the better,โ€ says Donovan. Robin Watkins, director of healthcare at Power to Decide, agrees. โ€œNew research and studies come out all the time. So itโ€™s important to know from the start when the information was written.โ€ 

That said, older research isnโ€™t always out of date. โ€œIf an article is more than 5 years old, it doesnโ€™t mean that itโ€™s wrong or useless,โ€ says Watkins. โ€œBut itโ€™s a good idea to double-check the information with another source. Or see if there are more recent studies.โ€

4. Give it the sniff test.

You know the saying that if something sounds too good to be true, it probably is? That goes for anything you find online. So be wary of any sites that promise instant results or miracle cures. โ€œFurther, any article online that starts with, โ€˜What they donโ€™t want you to know!โ€™ or any other conspiracy-minded outlook is probably bogus,โ€ Donovan says. 

Donovan also warns against getting health info on social media. โ€œIt may go against many peopleโ€™s instincts. But when it comes to medical information, establishment is really best.โ€

Finally, donโ€™t forget about the best sources of all: the doctors and nurses you know and trust. โ€œIf you have concerns, problems, or questions and you arenโ€™t finding the answers you need online, follow up with your healthcare provider,โ€ says Watkins. They can make sure youโ€™re getting the most up-to-date info possible.
