Study Notes
Secondary Amenorrhea
- Secondary amenorrhea is the absence of menstruation for more than six months in a woman of reproductive age.
- It is not due to pregnancy, lactation, or menopause.
- Women with secondary amenorrhea must have a patent lower genital tract, an endometrium responsive to ovarian hormone stimulation, and ovaries responding to pituitary gonadotropins.
Causes of Secondary Amenorrhea
- Uterine Causes:
- Asherman's Syndrome: Intrauterine adhesions prevent the normal growth of the endometrium. This can be caused by over-vigorous endometrial curettage or adhesions following endometritis.
- Ovarian Causes:
- Polycystic Ovary Syndrome (PCOS): The most common cause of secondary amenorrhea and is not related to estrogen deficiency.
- Premature Ovarian Failure (POF): Cessation of periods with elevated gonadotropin levels before the age of 40.
- Hypothalamic Causes:
- Hypogonadotrophic Hypogonadism (HH): May be caused by weight loss, exercise, chronic illness, psychological distress, or idiopathic factors.
- Pituitary Causes:
- Hyperprolactinemia: Elevated prolactin levels due to prolactin-secreting pituitary adenomas, non-functioning tumors, medications, or other conditions.
- Hypopituitarism: Deficiency in one or more hormones produced by the pituitary gland.
- Sheehan's Syndrome: Damage to the pituitary gland caused by postpartum hemorrhage.
- Systemic Causes:
- Chronic Diseases: May affect gonadal function due to weight loss, disease effects on the hypothalamic-pituitary axis, or direct effects on gonads.
- Endocrine Disorders: Hypothyroidism, Cushing's syndrome, and autoimmune endocrinopathies can be associated with gonadal dysfunction.
- Weight-Related Amenorrhea: Weight gain or loss can significantly affect gonadotropin regulation.
- Diabetes Mellitus: Can lead to functional hypothalamic-pituitary amenorrhea.
Diagnosis of Secondary Amenorrhea
- Evaluation: A thorough medical history and physical examination are crucial.
- Diagnostic Tests:
- Pregnancy Test: To rule out pregnancy.
- Hysterosalpingogram (HSG): Evaluates the uterus and fallopian tubes.
- Hysteroscopy: Allows direct visualization of the uterine cavity.
- Hormone Levels: Blood tests to check for imbalances in pituitary hormones, ovarian hormones, and thyroid hormone.
Management of Secondary Amenorrhea
- Treatment: Depends on the underlying cause.
- Asherman's Syndrome: Hysteroscopic adhesiolysis (surgery to remove adhesions).
- PCOS: Lifestyle modifications, medications to regulate hormones, and fertility treatments.
- POF: Hormone replacement therapy (HRT) for long-term management.
- Hyperprolactinemia: Dopamine agonists (bromocriptine or cabergoline).
- Pituitary Tumors: Surgery, radiotherapy, and hormone replacement therapy.
- Systemic Conditions: Management of underlying disease.
- Weight-Related Amenorrhea: Weight management.
- Diabetes Mellitus: Strict blood sugar control.
- Other Systemic Conditions: Focus on underlying disease management and preventing complications.
Fertility Issues in Secondary Amenorrhea
- Fertility Concerns: Amenorrhea can be a significant cause of infertility.
- Approach: Addressing the underlying cause of amenorrhea can often restore fertility.
- Fertility Treatments: Assisted reproductive technologies (ARTs) such as in-vitro fertilization (IVF) may be used to achieve pregnancy.
