Weight loss surgery can add complications during pregnancy for babies

(small for gestational age, SGA), after vasectomy.

Risk of low birth weight pregnancy

Infants of small gestational age are at greater risk for a range of problems, including hypothermia, hypoglycemia, infections, and neonatal asphyxia than are infants of normal weight.

Therefore, women are often advised to Wait at least 12 months after a mastectomy before trying to have a baby. Many European countries, including the United Kingdom, recommend waiting two years after gastric bypass and 12 months after other types of surgery.1

However, the optimal time from surgery to conception (BSCI) has not been determined. To learn more, Dr Ana Carreira and Dr Bárbara Araújo, Department of Endocrinology and Metabolism, Centro Hospitalar e Universitário de Coimbra, Coimbra, Portugal, and colleagues performed a retrospective study of 48 cases. pregnancy after cesarean section.

The average woman was 34.3 years old when she conceived and had an average BMI of 30.9. They had the following surgery: gastrectomy (37.5%), sleeve gastrectomy (35.4%), gastrectomy (22.9%), and pancreatectomy (4. 2%).

Research results

  • 14.6% of babies were conceived less than 12 months after mastectomy, another 14.6% at 12 to 24 months after surgery, and 70.8% had BSCI over 24 months.

  • The mean birth weight was 2980g and 26.3% of infants with SGA (defined in this study as a study of less than 90% of infants born at the same number of weeks of pregnancy).

  • The time from cesarean section to conception was significantly lower in SGA infants (23.1 months versus 64.7 months).

  • The analysis also found that the longer a woman waited to get pregnant, the lower her chances of having an SGA baby.

  • Each additional waiting month is associated with a 5% reduction in risk of having an SGA baby and 4.2g increase in birth weight.

  • The optimal time to wait to be found is at least 24.5 months. Women with a BSCI of less than 24.5 months were 15 times more likely to have an SGA baby than those who waited longer to conceive.

  • Finally, the risk of having an SGA baby is similar for different types of surgery.

Risks of conception and terminal surgery

Dr Araújo said: “The length of time from conception to surgery has a significant impact on birth weight, with a shorter interval associated with a higher risk of having a low-birth-weight baby.

“This may be because the rapid weight loss that occurs after an episiotomy makes it difficult for a woman to gain adequate weight during pregnancy. Rapid weight loss can also lead to nutritional deficiencies. It’s been a long time since surgery to conceive, says Dr. Carreira, allows a woman’s weight and nutritional status to stabilize. While this can be slightly adjusted on an individual basis, it is important that women undergoing episiotomy are aware of the risks of early conception and the benefits of delaying pregnancy.
