Health experts recommended obese women gain at least 15 pounds during pregnancy. The 2009 IOM guidelines now recommend a weight gain of 11 to 20 pounds. However, some health experts say the new recommendations may still allow for too much extra weight for obese pregnant women. Research shows obese women are more likely than normal-weight women to have pregnancy-related complications, like gestational diabetes, high blood pressure, preeclampsia, higher rates of C-section delivery and infant death. Research also shows babies born to obese moms are more likely to have excess body fat and insulin resistance. Thus, the cycle of obesity and health problems may be perpetuated into the next generation. Raul Artal, M.D., Obstetrician/Gynecologist with Saint Louis University says obese women who gain less than 10 pounds while pregnant are much less likely to develop pregnancy-related complications.

According to the CDC, about 4.3 million babies were born in the U.S. in 2007. During pregnancy, a woman needs to provide nourishment for herself and for the growing fetus. In 2009, the Institute of Medicine (IOM) issued updated guidelines on pregnancy weight gain, recommending women of normal pre-pregnancy weight gain 25 to 35 extra pounds.

By the end of the pregnancy, the weight of the baby accounts for about one-fourth of the total weight gain (roughly 7 to 8 pounds). Another seven pounds is for maternal stores of nutrients, protein and fat. The rest of the weight can be attributed to the placenta (1 to 2 pounds), amniotic fluid (2 pounds), uterus (2 pounds), breast tissue (2 pounds), body fluids (4 pounds) and maternal blood (4 pounds).

Parents will soon be able to determine the gender of their unborn accurately at early stages of pregnancy, a new study finds. Ultrasound performed in the second trimester had long been the easiest method to detect the gender of the fetus.

In cases, in which the determination of the gender needed to be performed in earlier stages due to medical reasons, however, invasive tests such as amniocentesis, associated with a small risk of miscarriage, were inevitable. More...

Nyree Paten gained so little weight during her recent pregnancy that some of her neighbors did not even realize she was expecting. A few days before her due date, she weighed only two pounds more than she had at her first prenatal visit.

But Ms. Paten, 35, of the Bronx, was under doctor’s orders to gain no more than 10 or 15 pounds — she was already about 100 pounds overweight. More...

Repeat teen pregnancy is much lower than average among mothers who participate in the University of Kentucky’s Young Parents Program, according to a study. The study followed 1,386 teen mothers who took part in the program and showed that less than 1 percent had a repeat pregnancy within three years, compared with 18.7 percent of teen mothers statewide, according to a UK release Thursday. The study was published in the Journal of Pediatric and Adolescent Gynecology last year. More...
