Infrequent or very light menstruation; risk factor for osteoporosis.
means menstrual cycles farther apart than 36 days but shorter than 180 days. This may normally occur during early adolescence and in perimenopause. It is commonly a protective form of hypothalamic suppression in association with weight loss, inappropriately intense exercise training, emotional stress or under-nutrition. It appears to precede the development of anovulatory androgen excess. When oligomenorrhea is related to hypo-thalamic suppression, estrogen levels are low; but when related to anovulatory androgen excess, estrogen levels are high or normal.
