Assessment of serum concentrations of the “satiety hormone” — peptide YY concentration in body weight disorders in girls with anorexia nervosa and obesity

Key Points

• The study aims to assess peptide YY concentrations in girls with anorexia nervosa and obesity, comparing them to healthy controls.
• Assessment of serum concentrations of peptide YY (PYY)
• Comparison between girls with anorexia nervosa, obesity, and healthy weight
• Analysis of hormonal differences related to energy homeostasis
• Significant disparities in PYY concentrations found among girls with various weight disorders compared to healthy controls.
• Possible implications for understanding energy regulation and adaptation to weight disorders.
