Adolescent medicine also known as adolescent and young adult medicine is a medical subspecialty that focuses on care of patients who are in the adolescent period of development. This period begins at puberty and lasts until growth has stopped, at which time adulthood begins. Typically, patients in this age range will be in the last years of middle school up until college graduation (some doctors in this subspecialty treat young adults attending college at area clinics, in the subfield of college health). In developed nations, the psychosocial period of adolescence is extended both by an earlier start, as the onset of puberty begins earlier, and a later end, as patients require more years of education or training before they reach economic independence from their parents.
Medicine is often categorized most simply as pediatric and adult, with the pediatric category covering from infancy through both childhood and adolescence. However, such categorization is further divided in some contexts, such that adolescent medicine can be a more specific focus within pediatrics and geriatrics can be a more specific focus within adult medicine.
Issues with a high prevalence during adolescence are frequently addressed by providers. These include:
- Sexually transmitted disease (working with specialists in pediatric endocrinology, adolescent obstetrics and gynecology, immunology infectious diseases, and urology and reproductive medicine)
- Unintended pregnancy (working with specialists in adolescent obstetrics and gynecology, especially in neonatology and maternal-fetal medicine; many – though not all – are medically risky or high-risk cases or to those with psychosocial, environmental, and socioeconomic challenges)
- Birth control (access to prescription or non-prescription contraceptive methods)
- Sexual activity (such as masturbation, sexual intercourse and sexual abuse)
- Substance abuse
- Menstrual disorders (such as amenorrhea, dysmenorrhea and dysfunctional uterine bleeding)
- Acne (working with specialists in dermatology who treat adolescents)
- Eating disorders like anorexia nervosa and bulimia nervosa (working with nutritionists and dieticians, and also specialists in pediatric mental health counseling, clinical psychology, and pediatric psychiatry, who work with adolescents)
- Certain mental illnesses (especially personality disorders, anxiety disorders, major depression and suicide, bipolar disorder, and certain types of schizophrenia; in concert with mental health counselors, clinical psychologists, and pediatric psychiatrists specializing in adolescent health care)
- Delayed or precocious puberty (often working with specialists in adolescent pediatric endocrinology, urology, and andrology)
Gay, lesbian and bisexual young people
Adolescents who are gay, lesbian or bisexual tend to demonstrate more risky health behaviors and have worse health outcomes compared to heterosexual youth, including:
- Substance abuse
- Eating disorders and body image
- Sexual behaviors, including unintended pregnancy involvement (Contrary to assumptions, gay, bisexual or lesbian youth are more likely to report involvement in pregnancy compared to their heterosexual peers)
- Homelessness, which affects health and access to care
The rising dominance of chronic conditions over acute conditions, along with dramatic improvement in life expectancy, has made the management of such chronic conditions in adolescence of greater importance: Chronic conditions and adolescent development are mutually impactful.
Chronic conditions often cause delay in onset of puberty and temporary or permanent impediments to growth; conversely the growth and hormonal changes can destabilize treatment for the chronic condition. An increase in independence can lead to gaps in self-management, for example, in the decreased management of diabetes.
Young peoples' access to health care
Marginalised young people’s access is affected by their ability to recognize and understand health issues; service knowledge and attitudes toward help seeking; structural barriers; professionals' knowledge, skills, attitudes; service environments and structures; ability to navigate the health system; youth participation; and technology opportunities. Marginalised young people’s healthcare journeys can be supported by advocates that help them navigate the health system.
Adolescent medicine providers are generally drawn from the specialties of pediatrics, internal medicine, med/peds or family medicine. The certifying boards for these different specialties have varying requirements for certification, though all require successful completion of a fellowship and a passing score on a certifying exam. The American Board of Pediatrics and the American Board of Internal Medicine require evidence of scholarly achievement by candidates for subspecialty certification, usually in the form of an original research study.
In the United States, subspecialty medical board certification in adolescent medicine is available through the specialty boards of American Board of Internal Medicine, the American Osteopathic Board of Neurology and Psychiatry, the American Board of Family Medicine, the American Osteopathic Board of Family Physicians, the American Board of Pediatrics, and the American Osteopathic Board of Pediatrics.

Relationship with college health
In the United States, the subspecialty of college health is closely affiliated with adolescent medicine. Many adolescent medicine fellowships include rotations in college-based student health clinics and many adolescent medicine physicians work in college health clinics.
In addition to membership in the organizations for their various specialties, adolescent medicine providers often belong to The Society for Adolescent Health and Medicine and/or The North American Society for Pediatric and Adolescent Gynecology.
