Common Conditions

What are the Common Conditions?
WebMD Editors compile the list of common conditions based on incidence and prevalence information from the CDC (Center for Disease Control) as well as their medical expertise on what medical conditions are common in the population at large. The list is alphabetized for easy reference. If a sponsor or advertiser on WebMD happens to be affiliated with a medical condition on this list, it is purely coincidental. Nothing should be implied by the medical conditions or order of the list except for the fact that these are deemed important by the WebMD medical editors. For more information, you can read our Editorial Policy, Sponsor Policy and Advertising Policy.
