FamiilyDoctor.org has a lot of basic, general information to help community patrons assess their health needs. A particularly useful link is their Neighborhood Navigator, which connects to local resources in food (including food pantries and emergency food), housing, transit, physical health, mental health, care, goods, family, work & education, and legal areas. Resources are listed individually as well as mapped, and tend to be community initiatives targeted to lower income areas. Main categories for locating health information include Diseases and Conditions, Prevention and Wellness, and Family Health by age group. Your Health Resources section includes categories for Drugs, Procedures & Devices, Health Tools, and Healthcare Management, as well as a medical dictionary, BMI calculator, immunization schedule for all ages, and a symptom checker tool which walks users through a "no/yes" tree to arrive at a possible diagnosis and advice. The site includes a nice "breadcrumb" path to easily find where you are. The site does include advertising.
