Overview
Adolescence is a stage of life marked by fast growth, puberty, learning, and increasing independence. Health in the teen years includes physical health, mental health, sexual and reproductive health, safety, and healthy relationships. Experiences during this period can affect well-being now and later in adult life.
Causes and Risk Factors
Teen health is shaped by many factors, including family life, school, friends, income, neighborhood safety, nutrition, sleep, and access to healthcare. Common risks include stress, bullying, violence, road injuries, substance use, poor diet, inactivity, and unprotected sexual activity. Social media and online experiences can also affect mood, self-esteem, and sleep.
Who Is Affected
All teenagers can face health challenges, but needs differ by age, sex, culture, disability, and life circumstances. Some teens may have higher risks, including those living with chronic illness, mental health conditions, poverty, discrimination, conflict, or lack of family or school support. Adolescents who are pregnant or parenting may need extra healthcare and social support.
Prevention
Prevention starts with regular health visits, recommended vaccines, balanced meals, physical activity, enough sleep, and supportive adults. Open conversations about emotions, relationships, consent, online safety, and substance use can help teens make informed choices. Wearing seat belts and helmets, avoiding impaired driving, and reducing access to alcohol, tobacco, and drugs also lower harm.
Diagnosis and Tests
Teen health needs are often assessed through routine checkups rather than one single test. A healthcare professional may review growth, blood pressure, vision, hearing, mood, sleep, menstrual health if relevant, sexual health concerns, and vaccine status. Depending on symptoms and risk factors, screening tests may be suggested for conditions such as anemia, depression, sexually transmitted infections, or other concerns.
Treatment Categories
Care depends on the issue and may include health education, counseling, mental health support, treatment for short-term illness, management of long-term conditions, and referral to specialists when needed. Some teens benefit from school-based services, community programs, or family support alongside medical care. Respect for privacy and age-appropriate communication are important parts of care.
Living With It
Healthy routines can support teens through rapid change. Regular sleep, daily movement, time offline, trusted friendships, and practical stress-management skills may help with energy, mood, and concentration. Parents and caregivers can support teens by listening without judgment, setting consistent boundaries, and encouraging healthcare visits when concerns come up.
Diet and Lifestyle
Teens need regular meals, a variety of nutritious foods, enough water, and activity that fits their interests and abilities. Sleep is especially important because the adolescent brain and body are still developing. Avoiding tobacco, vaping, alcohol, and non-medical drug use supports long-term health, and limiting late-night screen use may improve sleep.
When to Seek Medical Care
Arrange medical care if a teen has ongoing sadness, anxiety, major behavior changes, sleep problems, weight change, repeated headaches, fainting, unexplained pain, concerns about puberty, menstrual problems, possible pregnancy, or symptoms of infection. Care is also important after injuries, bullying, sexual violence, or substance use. If a teen talks about self-harm, hopelessness, or feeling unsafe, seek urgent professional help.
When It May Be an Emergency
Get emergency help right away for trouble breathing, chest pain, seizure, severe allergic reaction, major injury, heavy bleeding, confusion, unconsciousness, or suspected overdose. Emergency care is also needed if a teen has suicidal thoughts with a plan, has attempted self-harm, or is in immediate danger from violence or abuse. If local emergency services are not available, go to the nearest emergency facility or urgent medical center.
