Women who are obese are more likely to go past the normal 40 weeks of gestation
Once in labor tend to have slower and less productive labor progression
Women with BMI over 35 should deliver in a hospital with neonatal and anesthesiology services
In the absence of other complications, obesity is not an indication for induction or c-section
Prolonged Pregnancy and Longer Labor

The risk of delivering an infant weighing over 4,000g, or above the 90th percentile (macrosomia) is 1.7-2 times higher for women who are obese or morbidly obese
More than a third of infants weighing over 4,500g have shoulder dystocia, whereas normal weight pregnant women have a 0.2-3% occurrence of this complication

Delay pregnancy 12-36 months following bariatric surgery
Some studies suggest to delay pregnancy based on weight loss instead of a timeframe (i.e. if the patient is able to make it to their goal weight and maintain a stable nutritional balance they may be able to conceive earlier)
Recommendations for Pregnancy Post Bariatric Surgery
