Oligomenorrhea (Infrequent Menstruation)

Oligomenorrhea can be caused by:

• Hormone imbalance

• Infection

• Structural abnormalities

• Medications

• Diabetes

• Scarring from surgery

• Eating disorders

• Extreme exercise

Hormonal conditions that can lead to oligomenorrhea include:

• Polycystic ovarian syndrome (PCOS)

• Androgen-secreting tumors

• Cushing’s syndrome

• Prolactinoma

• Primary ovarian syndrome

• Hyperthyroidism

• Congenital adrenal hyperplasia

Medications that can lead to infrequent periods include:

• Hormonal contraceptives

• Antipsychotics

• Antiepileptics

How is oligomenorrhea diagnosed?

To diagnose oligomenorrhea, your doctor will conduct a physical exam, which may include an abdominal, pelvic and rectovaginal exam to look for signs of inflammation, scar tissue or masses. Your Hoag gynecologist or OB/GYN may also order blood tests to check your hormone levels and blood sugar.

Hoag’s advanced imaging capabilities can also be put to use to diagnose the cause of your condition. These procedures include:

• CT scans

• Pelvic and abdominal ultrasounds

• Magnetic resonance imaging (MRI)

What are the treatments for oligomenorrhea?

Treatments vary depending on the cause for your condition. They can include:

• Hormone therapy – your doctor may prescribe birth control pills or other hormone treatments if your oligomenorrhea is caused by a hormone imbalance.

• Surgery – if you have an androgen-secreting tumor, your doctor may recommend surgery to remove it.

• Lifestyle changes – if diet and exercise are thought to be behind your oligomenorrhea, your doctor may work with you to make lifestyle and nutritional adjustments.

• Mental health care – women who develop oligomenorrhea due to an eating disorder may require care from a nutritionist and therapist.

See your Hoag gynecologist or OB/GYN if you’re experiencing oligomenorrhea.
