Several studies have suggested an association between the premenstrual
phase of the menstrual cycle and changes in appetite and eating behavior.
This study examined the relation between phase of menstrual cycle and
frequency of binge eating in 15 normal-weight women with bulimia whose
eating behavior had been unaffected by placebo treatment during a
medication study. There was a modest but statistically significant
premenstrual exacerbation of binge eating.
