Evaluating Online Medical Information
One of the first things many of us do when we notice a new symptom is reach for our phone. Within seconds, we’re reading articles, watching TikToks, scrolling through Instagram reels, or joining Facebook groups looking for answers.
The internet has made health information more accessible than ever—but unfortunately, it has also made misinformation easier to spread.
As a primary care provider, I regularly meet patients who are understandably confused after reading conflicting advice online. One website says a supplement will cure everything. Another says a common medication is dangerous. Social media influencers confidently offer medical advice without any medical training.
So how do you know what to trust?
Here are a few questions to ask before believing—or sharing—health information you find online.
1. Who is providing the information?
This is the most important question.
Ask yourself:
Is the information coming from a physician, nurse practitioner, registered dietitian, pharmacist, or another licensed healthcare professional?
Is the author clearly identified?
Are their credentials listed?
Remember that having a large social media following does not make someone a medical expert.
2. Is someone trying to sell you something?
Be cautious when the “solution” to every problem happens to be a supplement, detox, vitamin pack, or expensive program.
That doesn’t automatically mean the information is wrong—but financial incentives can introduce bias.
Reliable medical advice focuses on education first, not sales.
3. Does it sound too good to be true?
Watch for phrases like:
“Miracle cure”
“Doctors don’t want you to know this”
“Works every time”
“Lose 30 pounds in one month”
“Reverse aging naturally”
Medicine is rarely that simple.
Good healthcare recognizes that every person is different and that treatments have both benefits and risks.
4. Are there scientific studies behind the claims?
Good medical information references research—not just personal stories.
One person’s experience can be meaningful, but it isn’t the same as scientific evidence.
The strongest recommendations usually come from multiple well-designed studies involving many people.
5. Is the information current?
Medicine changes quickly.
An article from 2014 may no longer reflect today’s recommendations.
Look for publication dates and make sure the information has been updated recently.
6. Be careful with social media
Platforms like TikTok, Instagram, Facebook, and YouTube can be great places to learn—but they’re designed to maximize engagement, not accuracy.
Videos that are dramatic, emotional, or controversial are often shown to more people, regardless of whether they’re true.
Even licensed healthcare professionals can oversimplify complex medical topics because short videos leave little room for nuance.
7. Look for consensus—not one loud voice
One expert saying something very different from everyone else should raise questions.
In medicine, we place much more confidence in recommendations that are supported by multiple experts and major medical organizations than by a single person’s opinion.
8. Beware of fear-based messaging
If a post makes you feel panicked or angry, pause before believing it.
Many misleading posts use fear because fear captures attention.
Good medical information should educate—not frighten.
9. Ask your own healthcare provider
The internet can provide general information, but it doesn’t know your medical history, medications, family history, or personal goals.
The best medical advice is individualized.
That’s one of the biggest advantages of Direct Primary Care—you have direct access to someone who knows you. If you come across an article, video, or social media post that raises questions, send it to me. I’d much rather help you sort through confusing information than have you worry unnecessarily or spend money on something that isn’t supported by evidence.

The Bottom Line
The internet is an incredible tool—but it’s also full of misinformation.
Healthy skepticism is a good thing.
Before changing a medication, starting a supplement, or worrying about a frightening diagnosis you found online, take a moment to consider where the information came from and whether it’s supported by good evidence.
