How to use online health related information wisely


Excessive online research can lead to unnecessary anxiety

Online medical or health-related information is beneficial when correctly interpreted and carefully used with common sense, but on the flip side, misinformation, misinterpretation or misuse can lead to serious physical and/or emotional harm. The growing problem associated with excessive online patient research has even led to a new medical condition called Cyberchondria, the unfounded escalation of concerns about common symptoms based on review of online literature and search results. Cyberchondria can lead to a high state of medical anxiety but there are worse consequences too. 

The danger of non-health professionals using the Internet for self-diagnosis or to diagnose others

  • Cyberchondriacs often delay care which can be more harmful than the value of information obtained.
  • You could miss something important.
  • You may conclude there is more wrong than actually is wrong and this leads to unnecessary stress and an additional set of problems.
  • You may take steps to cure an incorrect diagnosis which could allow the underlying problem to worsen or to exacerbate and/or lengthen the symptoms.
  • You may ignore something important if you are in denial about your symptoms.
  • If you address some symptoms of your problem but ignore others, you could be missing the main source of the problem. In turn, the main problem can become more serious if it remains undiagnosed.
  • When self-diagnosing psychological issues, you can miss an underlying physiological problem that results in psychological symptoms.

The advantages of combining online research with a qualified health professional consultation

  • Combining your own research with the input of a doctor enables you to take advantage of the different available options rather than being limited to one or the other.
  • A doctor can confirm or disprove what you find online with an examination and/or tests and then set you on an appropriate path to alleviate the problem or the symptoms.
  • If your online diagnosis is correct, a doctor can provide a plan to reduce or remove symptoms and can also help with the challenges related to chronic conditions.
  • If a frightening online diagnosis is wrong, a patient will benefit from the huge stress relief of knowing their diagnosis was wrong. Then a correct diagnosis can be made by the doctor with a plan to alleviate the problem and symptoms.
  • If an incorrect diagnosis is less serious than the actual problem, a doctor’s intervention can be critical to deal with the true problem in a manner that won’t worsen it.

What to know before you research online health information

  • Look for the credentials of the source to be certain the author is an appropriate (licensed) health professional. (Doctor, nurse, psychiatrist, psychologist, etc.)
  • Watch out for conflicts of interest. (A sponsored page will have bias towards its own products and services.)
  • Make sure the information is current (less than 3 years old) as things change in medicine.
  • Read through symptom lists completely without skipping anything. If many don’t apply to you, you likely don’t have what you’re reading about.
  • According to the U.S. Food and Drug Administration, it’s best to work with:
    • Sites ending with “.gov,” (Sponsored by federal government)
    • Sites ending with “.edu,” (Run by medical schools or universities)
    • Sites ending with “.org,” (Maintained by not-for-profit organizations)
    • Scientific journals or medical journals
  • Recent regulation allows internet service providers to sell browsing habits to third parties. Consider using a Virtual Private Network (VPN) or a browser that doesn’t track you if you want your browsing history to remain private.

Important things to keep in mind after your online research

The importance of meeting with a doctor

A doctor’s visit can bring needed relief!

After your online research, do not assume the worst but don’t ignore what’s going on either. In most cases there is likely a simple, non-life threatening explanation. When you have concerns, take action as soon as possible. Worrying yourself about what you found online is unhelpful and can make matters worse but scheduling an appointment with a doctor to discuss what you’ve found is helpful and intelligent. Lastly, all doctors are not equal and most doctors are not right 100% of the time. If you have reason to doubt a doctor’s diagnosis, explain this to the doctor so that the doctor can discuss your concerns with you and in turn, you can decide what to do after that. If you remain dissatisfied, a second opinion from another health professional is warranted. You are your most important advocate.

Until next time,… Stay Cyber Safe!

    Very informative article and suggestions. Firstly, people forget how many years you actually have to go to school to earn a doctorate degree. If it was as simple as Google, we wouldn’t need doctors! I think that doing your own research (so long as the sources are reputable or trusted, as you mention) is a good thing because it can lead to questions (for yourself and a healthcare professional). Having these questions answered by your healthcare professional can bring peace of mind and may even lead to best treatment scenarios. You’re right that all doctors are not equal and no doctor is right 100% of the time. It’s also important to remember that a doctor can sometimes only be as good as the information that they have…so if research and questioning helps you to provide better information to your doctor that allows them to provide better treatment, that’s a good thing!
