Premenstrual exacerbation of binge eating in bulimia.

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.
