The American Academy of Pediatrics recommends a yearly health checkup for all youths, aged 11 to 21. Because this is a time when many changes take place, a yearly exam is an important part of your teen’s health care. This visit gives your doctor a chance to do a physical exam, and you can ask questions about issues that arise during the teen years. It also helps your doctor follow your teen’s progress, including self-esteem and emotional balance. Plus, it's a great chance to encourage wellness and healthy behaviors, such as exercise and good nutrition.
