I'm linking to an article here on the Psych Central site about hypochondria, or Somatic Symptom Disorder.

If you do a web search, there are several quizzes about whether or not you're a hypochondriac.

I do think it's true that the internet makes it so easy for us to research symptoms and diseases that we can spend more time thinking about these than is probably good for us sometimes.

I view hypochondria as a continuum - you might be a little bit that way or you might be really bad. I think you have to look at how your researching symptoms is affecting your life.

You do seem to be saying that you think maybe this behavior is causing you some problems.

I have several chronic health conditions, so I deal with the problem myself of how much information is enough. I like to think that if I'm learning more about something that I've actually been diagnosed with, that the research is good. I've found, though, that even that can get out of hand.

I usually tend to research in bursts then I'll get bored with it and not do it for awhile.

I think that asking yourself "do I have those symptoms" is completely normal if we learn about a new disease or medical condition. Medical students do it.

If the learning is causing you problems, though, then it may be better to give up that research subject for a non-health one if you just like to research.

But the answer to the question in the first sentence of your post is "no".
