Document Summary
Nutritional needs change at each stage of the life cycle. Nutrients can reach the developing fetus through the placenta: the close association between the fetus"s and mother"s circulatory systems permits the mother"s bloodstream to deliver nutrients and oxygen and remove waste products. Pregnant women are 6x more likely to develop htn and gdm than those at ideal body weight. Obese women are more likely to experience difficulties during labor and delivery. More than 1 in 4 women will retain 10+ lbs by 12 months postpartum. Women who are obese are increased risk for preterm delivery. Smoking, alcohol and drug abuse, obesity and eating a poor-quality diet are associated with reduced fertility.
