The result of the study pointed out that the ideal waiting time for a pregnancy would be at least 24.5 months after the surgical procedure that helps in weight reduction.
A study showed that women, after undergoing bariatric surgery, should wait at least two years before starting a pregnancy.. The research was even presented at the European Congress on Obesity, in Maastricht, Netherlands, last Friday (6).
“The interval from bariatric surgery to conception has a significant impact on birth weight. Shorter intervals are associated with a greater risk of having a very underweight baby”, explains Bárbara Araújo, from the Department of Endocrinology and Metabolism at Centro Hospitalar. and University of Coimbra, in Portugal.
To find out the results, there was an analysis of a survey of 48 pregnancies after bariatric surgeries between the years 2008 and 2020. On average, the age of pregnant women was 34 years, in addition to a mean BMI (body mass index) of 30.9. The result of the study pointed out that the ideal waiting time for a pregnancy would be at least 24.5 months after the surgical procedure that helps in weight reduction.
If there is a pregnancy in a shorter period, a woman’s chance of conceiving a small for gestational age (SGA) baby is 15 times greater. In the survey, the average weight of children at birth was 2,980 kg and 26.3% of babies were considered SGA, compared to the others in the same period of pregnancy. That is, the longer a woman waits to get pregnant, the less chance of having a SGA baby.
“This is likely due to the rapid weight loss that occurs after bariatric surgery, making it difficult to gain adequate weight during pregnancy. Rapid weight loss can also lead to nutritional deficiencies that can be harmful to the baby. […] A longer interval between surgery and conception allows the woman’s weight and nutritional status to stabilize,” said Araújo.
