Abstract: Endometriosis represents the primary pathological cause of dysmenorrhea and chronic pelvic pain in adolescents, significantly impacting their physical and mental health as well as future fertility. The issue of delayed diagnosis is particularly pronounced in this population. Compared to adults, adolescent-onset endometriosis tends to present more insidiously, with a broader spectrum of symptoms that often overlap with gastrointestinal and urinary tract manifestations, frequently leading to pain syndromes. Given that adolescent cases are predominantly in the early stages, the absence of positive clinical signs or imaging findings does not exclude the possibility of endometriosis. Therefore, empirical pharmacological treatment should be initiated promptly in such patients. The short-term objective is to alleviate pain, while long-term goals focus on slowing disease progression and safeguarding future fertility.
