Adolescent Medicine

We offer comprehensive care to adolescents, including marginalized groups of youth with complex health and psychosomatic issues. Our specialists treat teens and children with eating disorders, severe obesity, obstetrics-gynecology conditions and other chronic diseases.


We provide care for teens and children with a variety of conditions and needs, including:

  • eating disorders
  • contraception in patients with chronic diseases
  • menstrual irregularities such as primary ovarian failure or polycystic ovary syndrome
  • teenage pregnancy
  • congenital abnormalities of the female reproductive system

Patients in need of hospitalization will be hospitalized on our medical and surgical wards at the Glen site. We also have a day hospital within the Psychiatry department available for patients with eating disorders.

In cases of sexual abuse, we conduct an evaluation that includes medical legal exams in cases of recent and chronic sexual abuse, for any child under the age of 18.
