Study examines pregnant obese women - Yahoo! News:
"Current recommendations developed by the Institute of Medicine in 1990 say women should gain at least 15 pounds during pregnancy, and the guidelines place no upper limit on pregnancy weight gain. The study found that women of different weights should gain or even lose different amounts of weight.
'The fear has been that not gaining weight would have a deleterious effect on the fetus,' said Dr. Raul Artal, study author and chairman of the department of obstetrics, gynecology and women's health at Saint Louis University School of Medicine.
'Not only were there no deleterious effects, but there are benefits. Women, by not gaining weight in pregnancy, reduce their risk of hypertensive disorder, have less C-sections and have babies of normal weight.' He added, 'The guidelines are outdated and we have to change them.'"
