Anorexia nervosa (AN) impairs bone health, leading to low bone mass and increased fracture risk. Weight restoration and specific hormone therapies show promise for improving bone density in adolescents and adults with AN.

Area of Science:

  • Endocrinology
  • Bone Metabolism
  • Adolescent Health

Background:

  • Anorexia nervosa (AN) is characterized by severe low weight, leading to low bone mass, impaired bone structure, and reduced bone strength, increasing fracture risk.
  • Adolescents with AN experience decreased bone accrual, raising concerns about suboptimal peak bone mass and long-term bone health.
  • Nutritional deficits, hormonal alterations, and changes in lean mass and fat depots contribute to impaired bone metabolism in AN.

Purpose of the Study:

  • To review current understanding of bone metabolism in anorexia nervosa.
  • To evaluate the efficacy of various therapeutic strategies for improving bone density in AN.
  • To identify optimal treatments for low bone density in AN patients.

Main Methods:

  • Literature review of studies on bone density in anorexia nervosa.

  • Analysis of hormonal and nutritional factors affecting bone metabolism in AN.
  • Evaluation of pharmacological and non-pharmacological interventions for bone health in AN.

    • Main Results:

    • Weight restoration and resumption of menstrual function are crucial for improving bone density.
    • Oral estrogen-progesterone and transdermal testosterone are ineffective for increasing bone density in AN.
    • Transdermal estradiol with cyclic progesterone improves bone accrual rates in adolescents with AN.
    • Risedronate may increase bone density in adult women with AN, but bisphosphonates require cautious use due to teratogenicity concerns.

    Conclusions:

    • Therapeutic strategies for low bone density in AN require careful consideration of patient age and fracture risk.
    • Physiological estrogen replacement shows promise for bone health in adolescent AN.
    • Bisphosphonates should be reserved for specific cases in women of reproductive age with AN and fractures, after other therapies fail.
    • Further research is needed to establish definitive therapeutic guidelines for low bone density in anorexia nervosa.
