Abstract:
Irregular menstrual cycles are a common complaint among adolescents. There are multiple etiologies for menstrual irregularities. It is important to have a stepwise approach, including obtaining a thorough medical history and performing a physical examination, when patients present. Understanding the characteristics of the menstrual cycle helps determine the etiology. This article discusses the differential diagnosis of irregular menstrual cycles, as well as the approach to evaluation and management. The common conditions and defining characteristics are also discussed. [Pediatr Ann. 2018;47(1):e23-e28.].

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
