Pregnancy outcomes in women with active anorexia nervosa: a systematic review

Abstract

Plain English summary It is a common myth that women with active anorexia nervosa are less likely to become pregnant. Generally, pregnancies in women with active anorexia nervosa are considered high risk. This review looked at pregnancy complications in women with active anorexia nervosa that affect the mothers as well as unborn and newborn babies. There are number of complications reported, most commonly, anaemia, increased chance of birth by C-section, increased risk of substance use in mothers, poor growth of unborn babies, and smaller babies at birth. Mothers with anorexia nervosa are less likely to suffer from pregnancy related diabetes and postpartum haemorrhage. Interestingly, women with active anorexia nervosa tend to have different pregnancy complications comparing to women without adequate nutrition and women in starvation. It is important to mention that although women with anorexia nervosa carry higher risk of complications during pregnancy, the risk can be reduced with the help of obstetricians and psychiatrists. After birth, paediatrician visits can help identify any issue with the baby. Symptoms of anorexia nervosa could potentially get worse after delivering a baby. It is important to continue regular visits to a psychiatrist.
