menstrual cycles longer than 35 days, fewer than eight yearly
Oligomenorrhea, also known as infrequent menstruation, refers to menstrual cycles that occur at intervals longer than 35 days, resulting in fewer than six to eight periods per year. This condition can be caused by various factors, including hormonal imbalances, polycystic ovary syndrome (PCOS), stress, significant weight loss or gain, and certain medications. It is important to diagnose and address the underlying cause to manage the condition effectively.
