How does being bulimic affect pregnancy?

Risk to baby. Bulimia deprives the growing baby of needed nutrients, and may seriously endanger both mother and child.
Risky. Bulimia can cause a woman to lose large amounts of potassium, which can affect her heart function and cause arrhythmias. In the worst case, a woman can die from this. It also affects her overall health and nutrition during pregnancy. Talk to your doctor and get help if you are pregnant and are bulimic.
