Cyberchondria
Makarand writes "According to this article in the San Francisco Chronicle the ever-expanding
wealth of health information online is keeping hypochondriacs constantly worried. With websites devoted to every major and
esoteric illness and search engines coming up with many disease possibilities
when you type in a symptom, it is becoming very easy for the health-anxious
to believe that they have a disease. Many continue poring through the easily
available medical information even after their doctors have given them
a clean bill of health."
The title says it all.

I'd just like to point out, that, as others have said, finding reliable health information on the Internet can be a bit difficult (everyone and their dog wants to give you advice).
This might help: It's a site set up by Health Canada with information from Health Canada and reliable sources (e.g. health organizations such as the Canadian Lung Society, university health sites).
