    Hypothalamic amenorrhea, often triggered by weight loss or stress, is linked to high serum carotene levels (hypercarotenemia) in otherwise healthy women. The exact cause remains unclear but may involve metabolic changes.

    Area of Science:

    • Endocrinology
    • Nutritional Science
    • Metabolic Disorders

    Background:

    • Hypothalamic amenorrhea is a condition characterized by the absence of menstruation due to disruptions in the hypothalamic-pituitary-ovarian axis.
    • Hypercarotenemia, an excess of carotene in the blood, can lead to yellow skin pigmentation (carotenoderma).
    • This study investigates a potential link between these two conditions.

    Purpose of the Study:

    • To describe a cohort of patients presenting with both hypothalamic amenorrhea and hypercarotenemia.
    • To explore potential triggers and clinical features associated with this combined presentation.
    • To investigate the relationship between weight loss, stress, and elevated serum carotene levels in the absence of excessive carotene intake.

    Main Methods:

    Related Experiment Videos

  • Case series describing six patients with hypothalamic amenorrhea.
  • Clinical evaluation including assessment for signs of anorexia nervosa and dietary habits.
  • Measurement of serum carotene levels.
  • Correlation of clinical findings with laboratory results.

    • Main Results:

    • All six patients had hypothalamic amenorrhea following weight reduction or stress.
    • None exhibited typical signs of anorexia nervosa or excessive carotene consumption.
    • Elevated serum carotene levels were observed in all patients.
    • Three patients displayed visible yellow skin pigmentation (carotenoderma).

    Conclusions:

    • Hypothalamic amenorrhea can be associated with hypercarotenemia even in the absence of excessive carotene intake or anorexia nervosa.
    • The underlying mechanism linking these conditions is not fully understood.
    • Metabolic shifts related to weight loss and catabolism may play a role in the development of hypercarotenemia in these patients.
