Health information on the Internet can be overwhelming and if your not careful very misleading. Initial searches bring up shallow commercial, wellness or media driven sites. Wikipedia is good for definitions and some times has some good references, but don't stop there. The good information is far harder to find. Look for support organisations, government and not for profits, where the information is generally far more balanced and detailed. These sites often have links and you need to keep following the trail.
To get a patient perceptive I have found blogs to be wonderful, but again be careful. People who have a minor condition or potential major condition but get through it quickly don't generally blog about it. So blogs don't give good balance and are over represented by patients with a poorer than average prognosis. Blogs also have links to useful and interesting sites, such as mine here.
Patient support forums are a great interactive way to get and share information with others with your condition. You learn a lot on coping and wellness from other patients and you learn from their eyes and experience, not the doctors. Also check out YouTube, iTunes University and podcasts, they often have easy to access and digest information. .
The advent of Health Information to the internet is fantastic. You are able to become fully informed and take a far greater role in your treatment. It will drive greater accountability and learning into the medical sector and is transforming how we interact with health professionals. Power to the Patient!
