Oligomenorrhea in Exercising Women

The 2009 document reviews the relationship between oligomenorrhoea (irregular menstrual cycles) and exercise, considering whether it is a mild form of polycystic ovarian syndrome (PCOS) or a separate condition related to energy deficiency. It suggests that while energy deficiency is a known cause of menstrual disturbances in exercising women, oligomenorrhoea may have different energetic and hormonal characteristics, including hyperandrogenism, which is common in PCOS. The review highlights the need for careful evaluation of metabolic and endocrine status in women with menstrual disturbances to ensure appropriate treatment, as strategies differ for conditions related to energy deficiency versus those due to hyperandrogenaemia. The document includes various types of studies that report on clinical, hormonal, and metabolic profiles of exercising women with menstrual disturbances and those with PCOS. It emphasizes the importance of further research to accurately diagnose the cause of oligomenorrhoea in exercising women and to avoid misclassification that could lead to improper treatment.
