Problems: Obesity and Pregnancy


We all know that being overweight carries consequences—increased risk of heart disease, diabetes, hypertension, etc.—but obesity during pregnancy prompts even more tangible complications. Annie Murphy Paul of The New York Times explains:
The challenges of caring for these patients begin early. “We perform an anatomical survey of the fetus, but in an extremely obese woman, the ultrasound signal often can’t penetrate through all the tissue,” Dr. Mark Chames, an obstetrician at the University of Michigan Health System in Ann Arbor, says. He must use a vaginal probe instead. A thorough examination is especially important in obese women, Chames said, because they are at greater risk of having babies with neural-tube defects and other malformations.

Birth brings more difficulties. The fetuses of obese women are often too large to fit through the birth canal; their mothers are about twice as likely as normal-weight women to need a Caesarean section. Longer surgical instruments are required, as are extra-wide operating-room tables, reinforced to support hundreds of additional pounds.

To head off such problems, patients at the bariatric obstetric clinic at St. Louis University in Missouri are counseled not to put on any pounds at all during pregnancy, and are even encouraged to lose weight. Dr. Raul Artal, the chairman of the ob-gyn department and the clinic’s director, acknowledges that the notion of weight loss during pregnancy can be startling. “It goes against everything we were taught in medical school, everything we’ve always told our patients,” he says. Some scientists warn that we still know little about the potential dangers of this approach. Emerging evidence, however, suggests that obese women who maintain or lose weight during pregnancy experience significantly fewer complications and deliver healthier babies.
Getting fat and pregnant is a dangerous cliché. Clearly, an obese mom is not eating healthfully—bad idea! According to Dr. Fuhrman a pregnant mother’s diet is vitally important to a developing baby’s health. He explains:
We know that children have sensitive vulnerabilities that are quite distinct from adults. Their exposure to chemicals in our environment is more potentially damaging than the same exposure at a later age. It is important to realize that the diet a woman eats during her pregnancy and even before her pregnancy effects the adult health of her future offspring. For example, a recent study shows a strong association in children who develop brain tumors with the mother’s consumption of hotdogs during pregnancy.1 Scientific evidence suggests that cigarette smoking during pregnancy is associated with testicular cancer in sons thirty-five to fifty years later.2 We may get away with risky behaviors when we imbibe in our later years, but when we gamble with our children, the stakes are much higher and the damage more profound.
Maybe I’m going out on a dangerous limb here, but, if you’re pregnant and eating unhealthfully. You’re perpetrating a tremendous act of irresponsibility and selfishness. Am I wrong on this?

Study: Fiber Cuts Preeclampsia-Risk


New research by the University of Washington School of Public Health and Community Medicine has determined that eating fiber reduces women’s risk of preeclampsia during pregnancy. Here’s some of the abstract via The American Journal of Hypertension:
Background: Substantial epidemiological evidence documents diverse health benefits, including reduced risks of hypertension, associated with diets high in fiber. Few studies, however, have investigated the extent to which dietary fiber intake in early pregnancy is associated with reductions in preeclampsia risk. We assessed the relationship between maternal dietary fiber intake in early pregnancy and risk of preeclampsia. We also evaluated cross-sectional associations of maternal early pregnancy plasma lipid and lipoprotein concentrations with fiber intake.

Conclusions: These findings of reduced preeclampsia risk with higher total fiber intake corroborate an earlier report; and expand the literature by providing evidence, which suggests that dietary fiber may attenuate pregnancy-associated dyslipidemia, an important clinical characteristic of preeclampsia.
Very science heavy for a dingy blogger like me—I had to Wikipedia preeclampisa—but dietary fiber is very health-promoting. Just check out this illustration from Dr. Fuhrman:

Breast-Feeding, Good Times!


A new study claims breast-feeding releases happy hormones into mothers making them feel content that their babies needs have been met. Reuters reports:
When a baby breast-feeds, it triggers a flood of the hormone oxytocin that releases milk from the mammary gland and a feeling of love and trust in the mother that ensures the baby's needs are met.

This reflex has long puzzled researchers because it requires large surges of oxytocin to pull off all of this. Using a special computer model, researchers from China, France, Italy, and the United Kingdom said on Thursday they now understand how it works.

Their study, reported in the journal PLoS Computational Biology, suggests that breast feeding not only taps the normal brain cells involved in secreting oxytocin.

It also recruits dendrites -- whose normal job is to create communication channels between brain cells -- into secreting the hormone.
Dr. Fuhrman is a huge advocate of breast-feeding. Just check out DiseaseProof’s healthy parenting category for more.

Fat Kids, Mom Ate Junk


A new study on rats has determined that mothers who eat junk food while pregnant or breastfeeding have obesity-prone children. WebMD reports:
"The maternal diet seems to influence and trigger events early in the life of their offspring," study researcher Stephanie Bayol, PhD, tells WebMD. "We found that by the end of their adolescence, the offspring from the junk-food-fed animals had increased blood sugar, blood fat, and decreased insulin sensitivity — all of which are associated with overweight and diabetes."

Bayol and colleagues at London's Royal Veterinary College gave pregnant rats normal rat chow. But they also gave them free access to cookies, chocolate, doughnuts, muffins, potato chips, candy, and cheese.

In earlier studies, they showed that the offspring of these rats liked high-fat, high-salt, high-sugar foods better than other rats. But the new studies show that even when never fed junk food themselves, the rats whose mothers ate junk food during pregnancy grew up fatter than normal rats.

"Their fat cells were larger, which might make them more prone to obesity and might make it harder for them to lose weight," Bayol says. "So there were lasting effects from their mother's consumption of junk food, even if they were not fed junk food after weaning."
There’s been a lot of news about diet and pregnancy lately, especially when it comes to the baby’s long term health. Check it out:
Seems like a good reason to ALWAYS eat healthy.
