Obese and morbidly obese women are more likely to have pregnancy complications and caesarean sections than women of average weight, according to a study published in the April 2004 American Journal of Obstetrics and Gynecology. The controlled study is one of the largest ever to look at obesity in pregnancy, following more than 16,000 pregnant women at 14 medical centers across the country.

Compared with women of normal weight, obese and morbidly obese pregnant women were at greater risk for gestational hypertension, preeclampsia, gestational diabetes, fetal birth weight greater than 4,000 grams, and fetal birth weight greater than 4,500 grams, the study finds.

Morbidly obese women who undergo gastric bypass weight loss surgery and lose weight report a higher rate of normal births and healthy deliveries if they lose weight prior to becoming pregnant.

In a study by Dr. Alan C. Wittgrove, past president of the American Society of Bariatric Surgery and pioneer of the laparoscopic technique, post-gastric bypass pregnancy indicates fewer risks than commonly reported by women who are obese during pregnancy. His study was conducted with nurse-practitioner Leslie Jester who had a low-risk pregnancy and delivered a healthy baby after gastric bypass surgery.

The Wittgrove Center has an active patient list of over 2000 people. The patients are informed to contact the Center when they become pregnant. In the study 41 women in the patient population became pregnant. Using personal interview, questionnaire, and review of perinatal records, pregnancy-related risks and complications were studied.

The study found less risk of gestational diabetes, macrosomia, and cesarean section than associated with obesity. There were no patients with clinically significant anemia.
