Functional hypothalamic amenorrhea (FHA) is linked to stress and weight loss, causing decreased LH pulses and hypercortisolism. New diagnostic markers like hypercortisolism and altered melatonin levels aid FHA diagnosis and treatment.

Area of Science:

  • Reproductive Endocrinology
  • Neuroendocrinology

Context:

  • Functional hypothalamic amenorrhea (FHA) is a common condition often triggered by psychological stress, physical stress, and weight loss.
  • These triggers are associated with decreased luteinizing hormone (LH) secretory pulse frequency and hypercortisolism.
  • Classical FHA symptoms like low gonadotropin levels and hypogonadism lack specificity, making diagnosis challenging.

Purpose:

  • To explore the underlying pathophysiology of FHA.
  • To identify novel diagnostic markers for FHA beyond traditional clinical signs.
  • To highlight effective treatment strategies for FHA.

Summary:

  • FHA is characterized by reduced LH pulse frequency and hypercortisolism, though reduced LH pulse frequency is difficult to assess clinically.

  • New diagnostic indicators include hypercortisolism, hypoprolactinaemia, and elevated night-time serum melatonin levels.
  • Diagnosis of FHA is often a diagnosis of exclusion, necessitating the identification of reliable biomarkers.

    • Impact:

    • Identifies new biomarkers (hypercortisolism, hypoprolactinaemia, melatonin) to aid in the diagnosis of functional hypothalamic amenorrhea.
    • Suggests that pulsatile gonadotropin-releasing hormone (GnRH) administration or naltrexone are successful treatments for FHA.
    • Improves understanding of FHA's complex etiology and diagnostic challenges, paving the way for earlier and more accurate interventions.
