  • Drug-induced: Drugs can cause amenorrhea. These drugs include contraceptives, antipsychotics, antidepressants, blood pressure medications, cancer chemotherapy drugs and some allergy medications.
  • Low body weight: Body weight that is 10% lower than normal can cause hormonal imbalances that can stop ovulation. Some condition such as bulimia and anorexia can cause this to happen.
  • Stress: Stress can alter the function of the hypothalamus, which is the area that controls the menstrual cycle. This is usually temporary and menstrual cycle will resume when the stress decreases.
  • Excessive exercise: Physical activity, such as ballet, that requires intense training may disrupts the menstrual cycle.
  • Disorders that cause a hormonal imbalance: This may include conditions such as polycystic ovary syndrome, thyroid disorder, pituitary tumor or premature menopause.

Your doctor may perform the following tests to determine diagnosis:

  • Asking about medical history, physical examination, and laboratory tests.

Computed tomography (CT) of the abdomen (belly) and pelvis is another possible test if abnormalities of the uterus or ovaries are suspected.

How is amenorrhea treated?

Treatment depends on the cause of the missing period. Primary amenorrhea that is caused by birth defects may require hormone medications, surgery, or both.

In some cases, a drug called medroxyprogesterone or estrogen replacement will help periods start in most women.

Other drugs may be used for women with adult-onset congenital adrenal hyperplasia, premature ovarian failure, and hypothyroidism.

Women with anatomic abnormalities may need surgery.

In women with amenorrhea due to polycystic ovarian syndrome (PCOS), treatment may include weight loss by dieting and exercise. Medicines such as metformin can also be given.

Women with hereditary causes of amenorrhea can see a genetics specialist for additional evaluation and treatment.
