menstrual irregularity
Abnormal menstrual cycle patterns in adolescents, requiring assessment within the context of ongoing pubertal development.
Full Definition
Menstrual irregularity in adolescence encompasses variations from normal menstrual cycle patterns, including irregular timing, abnormal flow duration or volume, or absent periods. During the first two years after menarche, irregular cycles are common due to immature hypothalamic-pituitary-ovarian axis function. Concerning irregularities include cycles shorter than 21 days or longer than 45 days, periods lasting longer than 7 days, or amenorrhea for more than 90 days. Evaluation must consider normal adolescent development, underlying medical conditions, nutritional status, exercise patterns, and psychosocial stressors. Treatment approaches are often conservative, focusing on education and reassurance while monitoring for pathological causes.
Usage
Usage note: Always consider normal adolescent development when evaluating menstrual irregularity in teenage patients.
