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 youโre reading online.

When youโre worried about a health symptom or want to learn more about a condition, whereโs the first place you turn? If youโre like most Americans, you probably head to your phone or computer and do a web search. And youโre sure to get plenty of results. But not everything that turns up will be trustworthy health information or advice you can count on.
โHealth disinformation is rampant on the Internet,โ warns Catherine Johnson, MD. Dr. Johnson is founder and medical director of Precision Medical Care. โSo 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 youโre reading online.
1. Look at what comes after the dot.
โWhen 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 websiteโs 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:
Thatโs not to say that sites ending in .com canโt be trusted. But be critical. If youโre 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. Itโs 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. Itโs helpful for scientists. But it doesnโt 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 isnโt always easy to figure out, especially if youโre not used to reading science journals. But you can usually find out on the journalโs website.
If you donโt quite get what youโre reading, donโt worry. โMany 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. โReading 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 studyโs findings in simple terms? Both point to more valid research.
3. Check the date.
โThe more current a study is, the better,โ says Donovan. Robin Watkins, director of healthcare at Power to Decide, agrees. โNew research and studies come out all the time. So itโs important to know from the start when the information was written.โ
That said, older research isnโt always out of date. โIf an article is more than 5 years old, it doesnโt mean that itโs wrong or useless,โ says Watkins. โBut itโs 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. โFurther, any article online that starts with, โWhat they donโt 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. โIt may go against many peopleโs instincts. But when it comes to medical information, establishment is really best.โ
Finally, donโt forget about the best sources of all: the doctors and nurses you know and trust. โIf you have concerns, problems, or questions and you arenโt finding the answers you need online, follow up with your healthcare provider,โ says Watkins. They can make sure youโre getting the most up-to-date info possible.
