Eating Disorders and Pregnancy

The two  most common types of eating disorders, anorexia and bulimia most commonly emerge during adolescence or young adulthood. When these illnesses linger into a woman’s reproductive years they can adversely impact not only her health but also her baby’s. It is critical to understand the impact of eating disorders and pregnancy.

Anorexia involves obsessive dieting or starvation to control weight gain. Bulimia involves binge eating and vomiting or using laxatives to rid the body of excess calories.

How do eating disorders affect fertility?

Eating disorders, particularly anorexia, affect fertility by reducing your chances of conceiving. Most women with anorexia do not have menstrual cycles, and approximately 50% of women struggling with bulimia do not have regular menstrual cycles.

The absence of menstruation is caused by reduced calorie intake, excessive exercise, and/or psychological stress. If a woman is not having regular periods, getting pregnant can be very challenging.

How is my pregnancy affected?

The following complications are associated with eating disorders during pregnancy:

Women who are struggling with bulimia will often gain excess weight, which places them at risk for hypertension. Women with eating disorders have higher rates of postpartum depression and are more likely to have problems with breastfeeding. The laxatives, diuretics, and other medications are taken may be harmful to the developing baby. These substances take away nutrients and fluids before they are able to feed and nourish the baby.
It is possible they may lead to fetal abnormalities as well, particularly if they are used on a regular basis.

Recommendations for Women With Eating Disorders:

If you are struggling with an eating disorder, getting help to overcome it is the best thing you can do for your reproductive and pregnancy health. The majority of women with eating disorders can have healthy babies if they have normal weight gain throughout pregnancy.
