The present paper traces the first descriptions of eating disorders ba
ck to the 11th century, Our aim is to contribute to a better understan
ding of eating disorders through a historical approach. We studied Ibn
u-Sina's ''Canon de la medecine'' (1035) as well as other arabic medic
al works including Ibnu-Rochd's (12th century) medical treatises that
comment Galien's manuscripts, Ibnu-Rochd's ''Colleget'' and Ibnu-Jazza
r's medical treatise (10th century). We observed much agreement betwee
n Ibnu-Sina's descriptive patterns and the current classifications of
eating disorders. It questions the importance of sociocultural factors
in the development of these disorders.
