The fetal complications are, fetal miscarriage, malformations, high birth weight, cerebral palsy, asphyxia and death, she added. Bariatric surgical procedures are used to help patients lose weight after natural methods failed. They work by restricting the amount of food the stomach can hold. Today, the most common types of weight loss surgeries are gastric bypass and sleeve gastrectomy. A laparoscopic sleeve gastrectomy – known as 'the sleeve' – is a non-reversible procedure. It involves removing 80 percent of the stomach. What's left is a tubular pouch shaped like a banana. With less space to hold food, the patient will consequently consume fewer calories. More importantly, the operation stabilizes a number of gut hormones which are off-balance in obese people, driving them to crave food when they don't need it. A gastric bypass divides the stomach into a small upper pouch and a much larger pouch. This limits how much food a patient can eat. The surgeon then rearranges the small intenstine to connect to the small pouches, acting as a bypass for food so it skips part of the patient's digestive system.
Johansson said that because weight loss surgery preceding pregnancy has positive and negative effects, pregnant women who had bariatric surgery should be considered as risk pregnancies. They should be given special maternal health services care, detailed dietary guidelines which include monitoring their intake of post-surgery supplements, and extra ultrasound scans to track fetal growth. ⓒ 2021 All rights reserved.

Intestinal obstruction during pregnancy is potentially life-threatening for the mother and about 17 percent of fetuses die as a result, the study team writes. Pregnancy may increase the risk because of the extra pressure and organ displacement caused by the enlarged uterus. An additional 1. 5 percent of the pregnant women with prior bariatric surgery underwent surgical diagnostic procedures without finding any diagnosis, compared to 0. 1 percent of pregnant women without prior bariatric surgery. Many factors influence whether or not obese women should have bariatric surgery first or after childbearing, so there is no black or white answer, Stuart said. 'The factors include, the age of the women, duration of infertility, previous pregnancies, previous abdominal surgery, etc. ' However, it's important to note that obesity also raises risk factors for various problems during pregnancy. 'The maternal complications include gestational diabetes, preeclampsia and a higher risk of cesarean section, ' Stuart said.

Using insurance data from 2002-2006, they identified 585 obese women aged 16-45 years who had undergone bariatric surgery, had at least one pregnancy and delivery, and had continuous medical insurance coverage during pregnancy plus two weeks after delivery. Of these women, 269 had surgery before delivery and 316 had surgery after delivery. Compared with women who delivered before surgery, women who delivered after surgery had substantially lower rates (75%) of hypertensive disorders, even after adjusting for factors such as age at delivery, multiple pregnancy, surgical procedure, pre-existing diabetes, and insurance plan. These results have important clinical, public health, and policy implications, say the authors. For example, bariatric surgery could be considered in women of childbearing age who wish to start a family, and have a BMI of 40 or more, or a BMI of 35-40 with associated conditions. Future research should also address long term maternal and child health after pregnancies and deliveries following bariatric surgery in terms of weight management, nutritional status, and burden of long term chronic disease, they conclude.
The study was published online Feb. 26 in the New England Journal of Medicine. U. S. health officials say more than one-third of American adults are obese, with a body mass index ( BMI, a height-weight calculation) of 30 or higher. Nearly 179, 000 obese people underwent weight-loss surgery in the United States in 2013, according to the American Society for Metabolic and Bariatric Surgery. While various techniques may be used, the surgery restricts the amount of food the stomach can hold and/or reduces the intestines ' absorption of calories and nutrients from food. Johansson and her colleagues used data from nationwide Swedish health registries to compare pregnancies between nearly 600 women who had given birth after bariatric surgery and more than 2, 300 women who hadn't had the surgery but had the same BMI. Only 2 percent of women who had weight-loss surgery developed gestational diabetes, compared to 7 percent of the other group, the researchers said. The surgical group was also much less likely to give birth to larger-than-normal babies.
Women who undergo weight loss surgery (or bariatric surgery) before becoming pregnant have a lower chance of developing gestational diabetes and giving birth to large babies, according to a recent study. On the other hand, these women are at risk for giving birth to small babies, researchers reported in the February 26 issue of the New England Journal of Medicine. "Since bariatric surgery followed by pregnancy has both positive and negative effects, these women, when expecting, should be regarded as high risk pregnancies, " said Kari Johansson, PhD, a nutritionist in the Department of Medicine, Solna, Karolinska Institutet, Stockholm, Sweden. Dr. Johansson said that these women should be closely followed during pregnancy and given advice on healthy eating, and taking supplements if necessary. Women with obesity are at risk for a number of complications during pregnancy, including having high blood sugar (gestational diabetes), babies born prematurely (more than 3 weeks before their due date), stillbirth (death of a baby during pregnancy), problems during delivery, and development of obesity in their children.
The research also had a few positive surprise findings as well. Women who had been through weight loss surgery were less likely to deliver excessively large babies, and were also less likely to suffer from insulin resistance or high blood sugar. Researchers say that this is the first study of it's kind that has been done on this subject, so more research is definitely needed to find out what exactly the correlation is. However, they hypothesize that the reason for the low birth weight and premature babies most likely has something to do with deficiencies in vitamins and minerals, which are often common in women who have bariatric surgery. Of course, there is still much work and research to be done in this field, and doctors are still figuring things out. If you have had weight loss surgery and are currently pregnant, make sure you tell your OB/GYN. Some doctors have experience dealing with this, but not all do. Talk with your doctor about how to make sure you are getting the nutrients that you need, and also how to reduce your risk of having a baby prematurely or with a low birth weight.
Weight loss surgery prior to pregnancy can dramatically reduce the risk of hypertensive disorder and other serious health conditions for obese women. More pregnant women than ever are either overweight or obese, causing them to be at risk for a slew of health conditions. A new study published in the British Medical Journal found that health problems like blood clots, hypertensive disorder, and preeclampsia can be reduced through weight loss surgery prior to conception. Researchers at Johns Hopkins University School of Medicine reviewed the medical records of 585 women of childbearing age who had bariatric surgery either before delivering a child or after. In the study, 316 women had weight loss surgery before getting pregnant, while 269 of the women gave birth before undergoing a bariatric procedure. According to the results, women who delivered after bariatric surgery had a 75 percent lower risk of hypertensive disorder in pregnancy than women who had a delivery before surgery. Hypertensive disorders can cause complications during and after pregnancy, and increase the chance of infant mortality.
