This week on Health Watch, we’ve been talking about taking a more active role in your own health management. You can do this by keeping track of important health information and communicating with your doctor. When it comes to your health, knowledge can be power. But it’s also possible to go too far.

Dr. Shelley Roaten Jr., chairman of family and community medicine at UT Southwestern, cautions about relying too heavily on your own Internet research about medical conditions. It’s good to learn about your health, but the Internet isn’t a substitute for your doctor. Plugging information into an Internet form can’t take the place of a doctor’s exam. When you research health information online, make sure you’re going to a reputable source that isn’t just trying to sell you something. Look for sites related to universities, professional organizations and government agencies.
