Amenorrhea

Amenorrhea is the absence of menstruation. It is classified as primary (absence of menses by age 15 in the presence of secondary sexual characteristics, or age 13 without them) or secondary (cessation of menses for more than three cycles or six months in a previously menstruating individual). It is a clinical sign, not a disease itself, reflecting underlying hormonal or anatomical dysfunction.

Etiology ranges from physiological states (pregnancy) to pathological conditions. Causes are categorized by the hypothalamic-pituitary-ovarian (HPO) axis: hypothalamic dysfunction (stress, eating disorders), pituitary disorders (tumors, Sheehan syndrome), ovarian failure (premature ovarian insufficiency), or outflow tract obstruction (Müllerian agenesis, imperforate hymen).

Amenorrhea results from the disruption of the pulsatile release of Gonadotropin-Releasing Hormone (GnRH), the feedback loop of the HPO axis, or anatomical blockage. In hypothalamic amenorrhea, low energy availability suppresses GnRH. In ovarian failure, the lack of estrogen precludes cyclic endometrial buildup and withdrawal bleeding.

Primary amenorrhea affects <1% of the female population. Secondary amenorrhea is more common, occurring in 3-4% of reproductive-age women, excluding pregnancy.

Extreme exercise, low body mass index (BMI), chronic stress, genetic chromosomal abnormalities (e.g., Turner syndrome), polycystic ovary syndrome (PCOS), and medications (antipsychotics, chemotherapy).

A. Early Symptoms: Irregular periods, spotting.
B. Common Symptoms: Infertility, cyclical pelvic pain (if obstruction exists).
C. Advanced Symptoms: Galactorrhea, signs of androgen excess (hirsutism, acne), hot flashes, vaginal dryness.
D. Emergency Symptoms: Severe cyclic abdominal pain suggesting hematometrocolpos (blood buildup).

Evaluation includes BMI, Tanner staging for sexual development, pelvic examination (to assess anatomy), and assessment for androgen stigmata (hirsutism).

A. Clinical Assessment: History of menstrual patterns and nutritional status.
B. Laboratory Testing: Pregnancy test (HCG), FSH, LH, TSH, Prolactin.
C. Imaging Studies: Pelvic ultrasound to confirm the presence of a uterus.
D. Functional Tests: Progestin challenge test.
E. Biopsy Findings: Rarely indicated unless malignancy is suspected.
F. Genetic Testing: Karyotyping for suspected Turner syndrome (45,X).
G. Differential Diagnosis: Pregnancy, PCOS, Hypothalamic Amenorrhea, Hyperprolactinemia.

Test Name: Human Chorionic Gonadotropin (hCG)
Type: Urine/Blood Test
Purpose: Exclude pregnancy
Expected Findings: Negative
Interpretation: If positive, pregnancy is the primary cause.

Pelvic Ultrasound: Assesses presence/size of the uterus and ovaries; used to identify anatomical obstructions.

Distinguished by FSH levels: High (ovarian failure), Low (hypothalamic/pituitary), or Normal (PCOS or outflow tract obstruction).

Osteoporosis (due to hypoestrogenism), infertility, endometrial hyperplasia.

A. Lifestyle Modifications: Weight restoration, stress reduction, balanced diet.
B. Preventive Measures: Maintaining healthy BMI.
C. Medical Treatment: Combined oral contraceptives (COC) to induce withdrawal bleeds, hormone replacement therapy, or dopamine agonists (for hyperprolactinemia).
D. Surgical Treatment: Hymenectomy (imperforate hymen).

Good for reversible causes (lifestyle); variable for primary genetic disorders.

Screening for early puberty onset; nutritional support.
