Can bulimia cause your period to be irregular?

Indeed, quite often!: Irregular periods are often a clue to doctors that their patient may be bulimic. I've read research that found 45% - 50% of bulimic women experienced this symptom. A possible reason is that when our body is being poorly nourished, it curtails ovulation to prevent that unnecessary demand on its energy resources. It is a signal to you to get the eating disorder under control and return to health.
