Amenorrhea

Mga Pangunahing Punto

• Ang amenorrhea ay kawalan ng regla sa reproductive-age clients na may ovaries at uterus.
• Ang primary amenorrhea ay tumutukoy sa kawalan ng menarche sa humigit-kumulang age 16; ang secondary amenorrhea ay kawalan ng menses nang hindi bababa sa tatlong magkasunod na cycles pagkatapos ng dating regular cycles.
• Ang pagbubuntis ang unang kondisyon na dapat i-exclude sa secondary amenorrhea evaluation.
• Kabilang sa etiologies ang endocrine, hypothalamic-pituitary-ovarian, tumor, congenital, nutritional, at lifestyle contributors.
• Ang chronic hypoestrogenic states ay maaaring magpataas ng bone-loss risk at nangangailangan ng long-term surveillance at prevention planning.

Pathophysiology

Ang amenorrhea ay sumasalamin sa disruption ng hypothalamic-pituitary-ovarian axis, target-organ anatomy, o systemic endocrine regulation. Sa primary amenorrhea, mas karaniwan ang congenital o chromosomal causes sa initial workup. Sa secondary amenorrhea, madalas na contributors ang pregnancy, anovulation, weight/nutrition changes, pituitary-ovarian pathology, at hormonal disorders.

Kapag matagal ang estrogen deficiency, maaaring magkaroon ng end-organ effects tulad ng reduced bone mineral density at mas mataas na long-term fracture risk. Kaya dapat tugunan ng treatment planning ang parehong menstrual restoration at prevention ng chronic complications.

Classification

• Primary amenorrhea: Walang menarche sa humigit-kumulang age 16.
• Secondary amenorrhea: Walang menstruation sa tatlo o higit pang magkasunod na cycles pagkatapos ng dating regular menses.
• Endocrine/hormonal causes: Hyperprolactinemia, thyroid dysfunction, Cushing-spectrum disorders, at kaugnay na hormonal imbalance states.
• Structural/anatomic causes: Congenital anatomic variations (halimbawa absent o obstructed reproductive structures).
• Lifestyle and functional causes: Makabuluhang weight loss, undernutrition, excessive exercise, at stress-related hypothalamic suppression.

Nursing Assessment

NCLEX Focus

Magsimula sa pregnancy exclusion at red-flag neurologic/endocrine cues bago mag-narrow down sa hindi gaanong urgent na causes.

• Kumpirmahin kung ang pattern ay primary versus secondary amenorrhea.
• Kumuha ng focused menstrual at reproductive history, kabilang ang prior cycle regularity at recent pattern changes.
• Mag-screen para sa associated endocrine cues: hirsutism, hair loss, headache, galactorrhea, at visual changes.
• Tukuyin ang lifestyle contributors gaya ng weight loss, inadequate nutrition, high exercise load, o severe stress burden.
• Suportahan ang ordered diagnostics batay sa suspected cause: beta-hCG, prolactin, FSH/LH/estrogen, thyroid panel, androgen studies (halimbawa testosterone/DHEAS), at targeted imaging.
• Sa primary amenorrhea pathways, asahan ang chromosomal/anatomic evaluation kapag indicated.
• Suriin ang long-term hypoestrogen risk at bone-health status sa prolonged amenorrhea.

Nursing Interventions

• I-prioritize ang napapanahong pregnancy testing at escalation ng concerning findings (severe headache, visual symptoms, o progressive endocrine signs).
• Suportahan ang etiology-directed treatment plans, kabilang ang hormonal regulation strategies kapag nireseta.
• Palakasin ang medication teaching para sa targeted therapies tulad ng dopamine-agonist pathways sa hyperprolactinemia contexts.
• I-coordinate ang multidisciplinary care para sa functional causes (nutrition, mental health, at exercise-specialist support) kapag may eating disorder o overtraining patterns.
• Palakasin ang bone-health prevention sa chronic amenorrhea: sapat na calcium/vitamin D intake, weight-bearing activity guidance, at follow-up bone-density monitoring ayon sa order.
• Magbigay ng emotional support at stigma-reducing education, lalo na kapag prominent ang fertility o body-image concerns.

Missed-Endocrine-Pathology Risk

Ang amenorrhea na may headache, galactorrhea, o visual change ay maaaring magpahiwatig ng pituitary pathology at nangangailangan ng agarang diagnostic escalation.

Pharmacology

Drug Class	Examples	Key Nursing Considerations
cycle-regulation hormonal therapy	Combined oral contraceptives, progestin therapy	Maaaring magdulot ng withdrawal bleeding at mag-regulate ng cycles sa selected etiologies; i-monitor ang contraindications at adherence.
dopamine agonists	Bromocriptine, cabergoline	Ginagamit para sa hyperprolactinemia-related amenorrhea; i-monitor ang symptom response at adverse effects.
bone-protection adjuncts	Calcium/vitamin D and selected osteoporosis therapies	Isaalang-alang kapag ang prolonged hypoestrogenism ay nagpapataas ng bone-loss risk.

Clinical Judgment Application

Clinical Scenario

Isang client na dating regular ang menses ay nag-report ng walang regla sa loob ng apat na buwan, recent weight loss, madalas na high-intensity exercise, at intermittent headaches na may galactorrhea.

• Recognize Cues: Secondary amenorrhea na may posibleng functional at endocrine contributors.
• Analyze Cues: Kasama sa differential ang pregnancy, hypothalamic suppression, at hyperprolactinemia/pituitary causes.
• Prioritize Hypotheses: Agarang priority ang pregnancy exclusion at endocrine red-flag workup.
• Generate Solutions: I-coordinate ang labs/imaging at multidisciplinary support habang sinisimulan ang safety-focused teaching.
• Take Action: Ipatupad ang ordered evaluation at palakasin ang nutrition/stress/exercise counseling.
• Evaluate Outcomes: Nalilinaw ang etiology, bumubuti o ligtas na namamanage ang cycles, at natutugunan ang long-term bone risk.

Related Concepts

• functional-reproductive-disorders - Ang amenorrhea ay pangunahing menstrual-pattern disorder sa functional reproductive care.
• causes-of-infertility - Magkakaugnay ang ovulatory dysfunction at hypothalamic/pituitary causes ng amenorrhea sa infertility pathways.
• ovulation-induction-agents - Maaaring kailanganin ang etiology-specific fertility treatment sa amenorrhea-related anovulation.
• diagnosing-pregnancy - Mahalaga ang maagang pag-exclude ng pagbubuntis bilang presumptive cause sa secondary amenorrhea.
• abnormal-uterine-bleeding - Ang amenorrhea at AUB ay magkaugnay na menstrual-pattern disorders na nangangailangan ng differential triage.
