Complications during pregnancy and childbirth are more frequent in women with active eating disorder symptoms during pregnancy, including malnutrition, miscarriage, preterm delivery, high incidence of cesarean sections, and low birth weight.

In the case of bulimia nervosa, the complications for the mother can be:

• Increased binge eating and vomiting.
• Excessive physical exercise.
• Little or excessive weight gain.
• Abortion.
• High blood pressure.

The risks to the baby are:

• Fetal death.
• Low birth weight.
• Low Apgar score.
• Breech birth.
• Cleft palate.

Psychological consequences also occur: intense fear of pregnancy and childbirth, postpartum depression, and anxiety.
