Functional hypothalamic amenorrhea: Impact on bone and neuropsychiatric outcomes

Area of Science:

• Reproductive Endocrinology
• Adolescent Health
• Neuroendocrinology

Background:

• Functional hypothalamic amenorrhea (FHA) is reversible hypogonadism in adolescents and young women.
• It stems from energy deficit (low intake or excessive exercise) or emotional stress.
• This adaptive response suppresses reproductive hormones, impacting overall health.

Purpose of the Study:

• To review the causes and consequences of FHA.
• To highlight the detrimental effects of FHA on reproductive, skeletal, and neuropsychiatric health.
• To emphasize the importance of early recognition and multidisciplinary management.

Main Methods:

• Literature review of FHA.
• Analysis of hormonal and health impacts.
• Synthesis of current understanding on FHA management.

Main Results:

• Energy deficit triggers FHA by suppressing gonadotrophin-releasing hormone secretion.
• Hypoestrogenism from FHA impairs bone mass acquisition and cognitive function.
• FHA is linked to increased risks of skeletal deficits, anxiety, and depression.

Conclusions:

• FHA poses significant risks to reproductive, skeletal, and neuropsychiatric health in young women.
• Maintaining adequate energy availability and estrogen levels is crucial during adolescence.
• Timely, multidisciplinary management is essential to mitigate long-term FHA effects.
