Oligomenorrhea is a medical condition characterized by infrequent or very light menstruation. It is common in women who have just begun menstruating and those approaching menopause. However, it can occur at any time during a woman's reproductive years.

Causes

Oligomenorrhea can be caused by a variety of factors, including stress, significant weight loss, exercise, and certain medical conditions such as polycystic ovary syndrome (PCOS) and hypothalamic amenorrhea. It can also be a side effect of certain medications, including contraceptives.

Symptoms

The primary symptom of oligomenorrhea is infrequent menstrual periods. Women with this condition may have fewer than six to eight periods a year. Other symptoms can include hair loss, acne, and increased body hair (hirsutism).

Diagnosis

Diagnosis of oligomenorrhea is typically based on a woman's menstrual history. Additional tests may be performed to rule out other conditions, such as pregnancy, thyroid disease, and PCOS.

Treatment

Treatment for oligomenorrhea depends on the underlying cause. If the condition is due to stress or weight loss, lifestyle changes may be recommended. If it is caused by a medical condition such as PCOS, treatment may include medication to regulate the menstrual cycle.
