DualDiagnosis writes in Issues and Dangers of Self-Diagnosis:

But sometimes people skip the doctor’s office, and they hop online to diagnose their own diseases. While this method might seem expedient, and it’s certainly common, it can be remarkably dangerous.

From Why Self-Diagnosing Yourself On The Internet Can Do You More Harm Than Good:

Dr Ravi Gaur, Chief Operating Officer (COO) at Oncquest Labs Pvt. Ltd., says, "Self-diagnosis can be very harmful because there are many disorders which have common symptoms.”


A slight misinterpretation can result in a wrong treatment of the disease that you don't even possess, therefore, it would be the right thing to trust your doctor and do not be an impatient patient!

Is there academic evidence that suggests that on average self diagnosis is more likely to be harmful than benefitial?

    The quotes and the question don't seem to match. – Nat Feb 11 '18 at 13:23

    Is your question about self-diagnosis vs a doctors visit or self-diagnosis vs nothing? The answer to the first question seems rather obvious, the second question seems more difficult to answer. – tim Feb 11 '18 at 15:10

    As @Nat pointed out, neither of the quotes says anything about "on average" or "more likely". They are hedged with the words "can be", which makes the actual claim pretty unremarkable. – purposeful porpoise Feb 11 '18 at 19:52

    This is way too vague to be a real question at the moment. Yesterday, my eyes felt like they wanted to close, and my thinking was a big vague and I wanted to sleep. Noticing it was past my bedtime, I self-diagnosed that I was tired and went to bed, despite these being symptoms of concussion. Clearly, we need to more precisely distinguish the claim. – Oddthinking Feb 12 '18 at 17:02

    I have edited in another quote from the second article that makes clear that the contradiction is "versus letting a doctor doing the diagnosis" (and edited the title accordingly) – user22865 Feb 12 '18 at 18:46
