Why This Even Needs a Guide
It’s no longer possible to ignore the fact that people are using the
internet for health-related information.
As of 2025, about two-thirds of internet users have looked up
health information — like flu symptoms, blood pressure, or
medications — and that number has remained steady over the
years. In addition, 62% of Americans use some kind of telehealth
service, with more than three-quarters seeing virtual care as the
future of healthcare.
This means the internet is no longer just a supplement to medical
advice — for many, it has become the main way to access it.
That’s why it’s important to learn how to use it wisely.
Step 1: Know What You’re Trying to Do
Before you start searching, decide which of the following you’re
trying to accomplish, because each one requires a different
approach.
You might be trying to understand a symptom or condition you
already have a diagnosis for.
You might be trying to assess whether something requires urgent
care, a scheduled appointment, or can wait. Or you might be
trying to get a real medical opinion, which usually means a
telehealth visit or an in-person appointment, not just an article.
Confusing these steps often leads to problems.
People start by trying to understand a symptom and end up
self-diagnosing something serious based on an article. So, it’s
It’s important to be clear about your purpose before you begin.
Step 2: Start With Credible Sources
Not all health-related websites are created equal.
Government and institutional sites — such as the CDC, NIH,
MedlinePlus, Mayo Clinic, or a hospital’s patient education pages
— are usually written or reviewed by licensed healthcare
professionals and are regularly updated. On the other hand,
independent blogs, forums, or wellness sites may not be reviewed
by medical professionals, even if they appear well-designed.
A quick way to check if a site is reliable: look at the bottom of the
article.
Reputable medical content will often list the name of a medical
reviewer with real credentials and include a “last updated” date. If
neither is present; treat the information as an opinion rather than
as reliable guidance.
Step 3: Read the Symptoms, Not Just
the Headline
This is where most self-diagnosis issues begin.
A headline like “5 Signs of a Serious Illness” is meant to draw
clicks, not to match your specific situation. Skim past the headline
and read the body of the article carefully. Look for how specific
The symptom descriptions are—do they mention duration?
severity, and how it differs from a harmless version of the same
symptom?
Serious conditions often share symptoms with common or
harmless ones.
For example, a headache can mean you’re dehydrated or, in rare
cases, something more serious. The article’s role is to help you
differentiate between these possibilities, not to scare you into
assuming the worst.
Step 4: Use Symptom Checkers as a
Tool, Not a Diagnosis
Online symptom checkers, like those from WebMD, Mayo Clinic,
or app-based services, are good at one thing: helping you
determine whether something needs urgent attention, a routine
appointment, or just to wait and observe.
However, they are not designed to provide a specific medical
diagnosis.
Use the results as a way to sort out your options.
If it says to seek care within 24 hours, take that seriously. If it lists
several possible conditions, don’t focus on the most alarming one
— it’s just a list of possibilities, not a ranked list of probabilities.
Step 5: Recognize When You’re Going
from Research to Worry
There is a clear pattern here, and it’s worth acknowledging
honestly: a survey of 2,000 Americans found that 43% had
misdiagnosed themselves after searching symptoms online, and
74% said the results made them more worried.
This is not unusual — it’s common among most people.
A few signs that you’ve moved from helpful research to unhelpful
worries include opening more than five tabs on the same
symptom, only searching for worst-case scenarios instead of your
actual symptom, or spending more than 20 minutes and feeling
more anxious than informed.
When this happens, close the tabs and contact a nurse line.
message your doctor, or book a telehealth visit — that’s the real
next step, not another tab.
Step 6: Use Telehealth for Advice, Not
Just Prescriptions
This is probably the most significant change in recent years.
It’s no longer about “Should I use telehealth?” — it’s about “When
Should I use it?” Telehealth use is now about 38 times higher than
it was before the pandemic, and it’s still around, not a short-term
trend.
Video or phone visits work well for follow-ups, medication
questions, mental health check-ins, and non-emergency
symptoms where a clinician can assess you without a physical
exam.
However, it isn’t a substitute for in-person care when something
requires physical examination, imaging, or testing — such as a
rash needing closer inspection, a lump, chest pain, or any issue
that involves actual physical findings.
Step 7: Bring Your Research to the
Appointment – Don’t Let It Replace the
Doctor
It’s perfectly fine to come to a doctor’s appointment having looked
Look up your symptoms online.
Most doctors understand this and don’t take it personally. In fact,
many doctors appreciate it when patients come prepared with
specific questions instead of vague statements like “I don’t feel
right.”
The way you present your information is important.
Asking something like, “I read that this could be X or Y — does
“That matches what you’re seeing?” encourages a discussion.
However, saying, “I already know it’s X, just confirm it,” can come
off as dismissive. The first approach creates a conversation, while
the second may make the doctor feel like they’re trying to guide
you away from an incorrect conclusion you made on your own.
Red Flags That Signal a Health Source
Might Not Be Reliable
There are certain signs that often appear in low-quality health
content.
Once you notice them, you’ll start seeing them everywhere. Be
wary of articles that claim a single food, supplement, or “secret”
can cure a wide range of illnesses — real medicine is rarely that
straightforward. Also, watch out for content that has no author, no
reviewer, and no date, especially when it talks about medications
or dosing. Another red flag is anything that tells you to distrust
your doctor and follow the article instead — legitimate medical
Writing guides you toward professional care, not replaces it.
On the other hand, signs of a trustworthy source are usually
straightforward: a named author or reviewer with proper
credentials, citations to studies or institutions, an updated date,
and language that shows awareness of uncertainty when it exists.
Confidence and medical jargon don’t always mean accuracy.
Sometimes the opposite is true. Real medicine often involves
saying “it depends”, which low-quality content tends to skip for the
sake of catchy headlines.
Seeking Advice for a Child vs. Seeking It
for Yourself
This deserves its own section because the stakes and the
sources change significantly when a symptom belongs to your
child.
Paediatric symptom checkers and advice are different from adult
ones — a mild fever in an adult could mean the same-day visit for
an infant. Also, medication dosing for children is based on weight,
not on one-size-fits-all guidelines that adult advice sometimes
assumes.
Stick to sources that are specifically designed for paediatric use
— such as a children’s hospital website, your paediatrician’s
patient portal, or a nurse advice line — rather than adapting adult
health information and assuming it applies to children.
It rarely does, and the margin for error with young children,
especially infants, is much smaller than with a healthy adult who
can wait a day or two.
What to Do When Two Sources Give
Conflicting Advice
This situation happens all the time and often confuses people.
One article says to rest a sprained ankle completely, while
Another suggests gentle movement speeds up healing. One site
says a fever should always be treated with medicine, while
another says a moderate fever is helpful and doesn’t always need
to be suppressed.
When sources disagree, the solution isn’t to take an average or
Choose the one that seems more confident.
Instead, bring the disagreement to your doctor or a telehealth provider.
provider and ask, “I’ve seen conflicting advice on this — what
does that mean for my specific situation?” That question often
leads to a better answer than either article alone, because it
forces a professional to consider the nuances instead of you
trying to figure it out on your own.

It’s not complicated.
It’s just a habit most people never learn, because no one teaches
how to research health information responsibly in school.
FAQ
Is it safe to get medical advice from a chatbot or AI tool?
It’s okay for general understanding and to help organise your
thoughts before an appointment. It’s not a substitute for a physical
exam, lab tests, or imaging, and it can’t examine you — so use it
as a starting point, then consult a real clinician for anything
beyond general information.
What’s the difference between a symptom checker and real
medical advice?
A symptom checker uses pattern recognition to estimate how
urgent a situation might be. Medical advice comes from a
professional who can examine you, order tests, and consider your
full medical history. They are not the same, even if the symptom
The checker feels thorough.
Should I trust a health website that doesn’t list its sources?
Be careful. Credible medical content usually includes citations or
names of reviewing clinicians. If a site makes strong claims
without any references, that’s a reason to double-check
information from another source before making a decision.
