The National Women's Health Information Center (NWHIC) is a service of the Office of Women's Health, which was originally established in 1991. Without a doubt, this fine site will be of great interest to health care professionals, educators, and a wide segment of society. Their homepage offers a wide array of helpful resources, divided into topics such as pregnancy and breastfeeding, funding opportunities, and a set of health tools. The health tools area is particularly useful as it offers such resources as ovulation calculator, a BMI calculator, and a heart disease risk test. Visitors to the homepage will also want to look through the day's health news, search their event calendar, and access the most recently updated sections. Finally, a number of these resources are available in Spanish.
