DirectionalDemographics and Risk Groups Interpretation
This stark portrait of bulimia nervosa reveals a disease that, while stereotyped as a young, affluent white woman's struggle, is in fact a complex genetic and psychological trap that disproportionately ensnares young women at the precipice of adulthood, yet also reaches silently into diverse communities, from single-parent homes to the diabetes clinic, proving its cruelty is both shockingly common and profoundly indifferent to the boxes we try to put it in.
