    The study examined autonomic responses to social exclusion in twins with and without symptoms of functional gastrointestinal disorders and eating disorders.

  • 2

    Participants included 35 monozygotic and dizygotic twin pairs, with zygosity confirmed through genetic blood testing.

  • 3

    Heart rate variability, skin conductance, skin temperature, and subjective stress ratings were assessed during a controlled social exclusion task.

  • 4

    Results indicated significant changes in physiological and subjective stress responses across experimental phases, but no differences between symptom groups.

  • 5

    Exploratory analyses suggested that both genetic and environmental factors may influence individual differences in stress reactivity.
