Mother’s weight loss surgery associated with premature birth
To do so, they used the Framingham risk calculator to estimate the before-and-after 10-year risks of heart disease, stroke, death, kidney disease and complications such as diabetic retinopathy and poor circulation. (The Framingham risk calculator is derived from probabilities gleaned from following more than 10,000 subjects in Framingham, Mass., in the Framingham Heart Study, which started in 1948.) In this study, the bariatric patients lost 60% of their excess weight and 61% saw their diabetes remit after surgery. Overall, their risk of having coronary heart disease, stroke or peripheral heart disease dropped by 27%. Bariatric surgeon Dr.

The analysis revealed that 5.2 percent of infants born to women whod had weight-loss surgery were small for gestational age garcinia cambogia side effects and 4.2 percent were large for gestational age. This compared to 3 percent and 7.3 percent, respectively, of those infants whose mothers had not had the surgery. The researchers also found that 9.7 percent of the infants born to mothers whod had weight-loss surgery arrived prematurely (before 37 weeks), compared with 6.1 percent of other infants. No differences were seen between the two groups in rates of stillbirth or death within the first 27 days after birth, according to the study published online Nov. 12 in the journal BMJ. Although the study found an association between women having weight-loss surgery and higher risk of pregnancy with prematurity or lower birth weight, it did not establish a cause-and-effect relationship.

Weight-Loss Surgery Linked to Risk of Preemie Birth
In a new study published in the British Medical Journal (BMJ), Swedish researchers have found that babies born to mothers who had bariatric surgery may have a greater chance of being born premature and being small for their gestational age. “The mechanism behind how surgery influences fetal growth, we don’t yet know, but we do know that people who have bariatric surgery are at increased risk of micronutrient deficiencies,” Dr. Olof Stephansson, obstetrician and associate professor of the clinical epidemiology unit at Karolinska Institutet, said in a statement. For the study, Stephansson and his colleagues analyzed 2,500 babies born between 1992 and 2009, whose mothers had all undergone weight-loss surgery. The babies were compared to a control group of 12,500 infants, whose mothers did not have surgery. Of the babies who had been born to moms who had undergone surgery, 5.2 percent were considered small for their gestational age as opposed to 3 percent of the babies born to moms who didnt have surgery. Additionally, only 4.2 percent of the babies whose mothers had surgery were considered adequately sized, compared to 7.3 percent of the control group.
