Eating disorders and pregnancy complications

No items found.
No items found.

Eating disorders, such as binge eating disorder, bulimia nervosa, and anorexia nervosa, often start in adolescence or young adulthood and affect countless individuals in their reproductive years. It’s estimated that eating disorders may affect up to 7.5% of pregnant people. (1) 

However, the rate of eating disorders among pregnant people may be even higher, as many don’t feel comfortable disclosing their eating disorders to their doctors due to shame or stigma or other fears or concerns. This feeling is understandable as medical professionals and other healthcare professionals can stigmatize people with diverse bodies, especially those in larger bodies. 

Nevertheless, eating disorders can have detrimental effects on the health of the gestational parent and baby so, not to mention the mental health suffering, it’s essential to seek help and support during this tumultuous time. Receiving care from an inclusive, specialized eating disorder treatment program can help patients heal from their disordered eating and to embrace their changing bodies throughout pregnancy.

Complications of disordered eating during pregnancy

Disordered eating and eating disorders can lead to several harmful consequences for the birthing parent and the baby, but seeking treatment as soon as possible can help rectify some of these risks and promote nutrition, healthy weight gain, and a healthier relationship with food. 

Risks for the pregnant person

Some potential risks for a pregnant person with an eating disorder may include: (2,3)

  • Psychological distress 
  • Postpartum depression
  • Anemia
  • Increased risk of hyperemesis gravidarum (excessive nausea and vomiting that may require hospitalization)
  • Poor nutrition
  • Dehydration
  • Gestational diabetes
  • High blood pressure
  • Premature birth
  • Labor complications
  • Nursing problems
  • Heart issues

It’s important to remember that many of these risks for the pregnant parent may negatively impact the baby’s health and development, especially if they become life-threatening. 

Risks for the fetus

Eating disorders not only affect the pregnant person but the developing fetus as well. Possible fetal complications include: (2,3)

  • Low birth weight
  • Respiratory distress
  • Poor development
  • Premature birth
  • Feeding issues
  • Miscarriage
  • Microcephaly (small head)
  • Premature labor

Not all of these risks will apply to everyone, as each type of eating disorder comes with its own possible fetal complications. 

Patients with eating disorder behaviors may have significant struggles with food, placing them at risk for development of high blood pressure and gestational diabetes.3 If a pregnant person is unable to control their gestational diabetes, this can cause the fetus’ blood sugar to be too high and for the baby to grow too large. A baby that is too big can cause delivery issues for both the delivering parent and the baby.4

An individual struggling with bulimia nervosa may experience irregular heartbeat, electrolyte imbalances, and dehydration. (3) Dehydration can lead to complications, such as low amniotic fluid, low breast milk production, and premature labor. (5) 

A pregnant individual who has anorexia nervosa may be underweight and not gain the appropriate amount of weight during pregnancy. This could lead to low birth weight as well as other health problems for the baby. (3)

Seeking eating disorder treatment during pregnancy

Many pregnant people with eating disorders may refrain from disclosing their eating disorder to their healthcare provider, but this can increase the risk of both parental and fetal complications. However scary it may be, the safest route is to disclose this information to a medical professional so the pregnant person can receive quality eating disorder treatment as soon as possible. The faster that care can be provided the better the outcome of the pregnancy.

Here are some tips for recovering from an eating disorder during pregnancy: 

  • Strive to be as honest and forthcoming as possible with your healthcare provider about any past or present eating disorders or disordered eating—if they aren’t sensitive or don’t seem to be experienced in treating people with eating disorders, seek out a different provider.
  • Meet with a nutritionist who specializes in eating disorder nutrition and create a plan for  appropriate nourishment and healing from the struggles you are experiencing with food throughout pregnancy and after birth.
  • Schedule additional prenatal appointments, if recommended by your doctor.
  • Find a therapist who specializes in eating disorder care and understands the unique struggles of recovery during pregnancy.
  • Attend support group meetings where you can find a strong and empowering recovery community.
  • Attend other prenatal, childbirth, or parenting classes to prepare you for this major life change.
  • Consult with your doctor before attending an exercise class or creating an exercise plan for yourself to ensure that it complies with your eating disorder recovery plan. Be mindful that all exercise is not healthy for you, especially if you are experiencing an eating disorder coupled with pregnancy.

Tips for improving body image during and after pregnancy

Pregnancy can be a huge adjustment for anyone, but pregnant people who have an eating disorder or disordered eating are particularly susceptible to the struggles of bodily changes during this time. Changes in body shape or size can be triggering for eating disorder relapse. Other people can also worsen these triggers if they make increased comments about the pregnant person’s weight, make unwanted comments about body shape or size, or touch the belly without permission. 

Here are some tips for improving body image during pregnancy:

  • Be aware of your triggers and work with your therapist to build healthy coping skills
  • Follow body-positive pregnancy accounts on social media
  • Block, mute, and unfollow any harmful social media accounts
  • Surround yourself with a positive and uplifting support system
  • Always ask for extra help or support if you need it
  • Attend a pregnancy support group, where you will interact with pregnant people of all different body sizes
  • Try to reframe your concerns over body weight or shape by focusing on celebrating the growth and development of your baby

After giving birth, many people may still struggle with body image issues, especially if they are concerned their body hasn’t returned to how it looked prior to pregnancy. The influence of “mommy bloggers” touting ways to lose that post-pregnancy baby weight aren’t helping either—they only serve to stigmatize people with diverse body types and to promote unrealistic body ideals. 

Compound these anxieties with the stress of being a new parent, and it’s no surprise that this can be a very distressing time for people with an eating disorder. It can be easy to fall into a pattern of obsessing over weight, stretch marks, and loose skin after giving birth, but try to remember that your body has just done something absolutely incredible, and you should be very proud. While you bond with your new baby, it can also be helpful to focus on how you plan to create a healthy and body-positive environment for your child while continuing your journey of healing.

Disclaimer about "overeating": Within Health hesitatingly uses the word "overeating" because it is the term currently associated with this condition in society, however, we believe it inherently overlooks the various psychological aspects of this condition which are often interconnected with internalized diet culture, and a restrictive mindset about food. For the remainder of this piece, we will therefore be putting "overeating" in quotations to recognize that the diagnosis itself pathologizes behavior that is potentially hardwired and adaptive to a restrictive mindset.

Disclaimer about weight loss drugs: Within does not endorse the use of any weight loss drug or behavior and seeks to provide education on the insidious nature of diet culture. We understand the complex nature of disordered eating and eating disorders and strongly encourage anyone engaging in these behaviors to reach out for help as soon as possible. No statement should be taken as healthcare advice. All healthcare decisions should be made with your individual healthcare provider.
