Bulimia from a gynecological view: hormonal changes

Area of Science:

• Reproductive endocrinology
• Gastroenterology
• Gynecology

Background:

• Gynecological problems are common in eating disorders.
• Bulimia nervosa is studied due to its link with menstrual disturbances, anovulation, and hormonal changes.
• Amenorrhea is a diagnostic criterion for anorexia nervosa.

Purpose of the Study:

• To assess the role of improper eating habits in the etiology of menstrual disturbances, anovulation, and hormonal changes.
• To investigate the connection between bulimia nervosa and infertility.
• To examine hormonal profiles in infertile women with bulimia nervosa.

Main Methods:

• Studied 58 infertile subjects who underwent the Bulimia Investigation Test, Edinburgh (BITE).
• Assessed clinical and subclinical bulimia nervosa cases (n=14).
• Correlated BITE test scores with body mass index and analyzed FSH and LH hormone levels, diagnosing multicystic ovary (MCO) and polycystic ovary syndrome (PCOS).

Main Results:

• BITE test symptom and severity subscales significantly correlated with body mass index (p=0.003).
• All 14 patients with clinical and subclinical bulimia nervosa exhibited pathologically low FSH and LH levels.
• MCO was diagnosed in 4/6 patients with clinical bulimia nervosa, and MCO/PCOS in 7/22 patients with eating disorders not otherwise specified (EDNOS).

Conclusions:

• Unsatisfactory nutrition in bulimia nervosa leads to hormonal dysfunction, menstrual disturbances, and infertility.
• Early treatment of eating disorders may reverse hormonal status, suggesting a more appropriate approach than immediate estrogen replacement.
• The use of hormonal contraceptives in therapy warrants reconsideration.
