Document Summary
Two changes generally occur in the eye during pregnancy. First, intraocular pressure decreases, probably as a result of increased vitreous outflow. Second, a slight thickening of the cornea occurs, which is generally attributed to fluid retention. Although these changes are not readily perceived, some pregnant women experience difficulty wearing previously comfortable contact lenses. The change in the corneas generally disappears by 6 weeks postpartum. Growth of the uterus and its contents, growth of the breasts, and increases in intravascular fluids account for most of the weight gain in pregnancy. In addition, extra water, fat, and protein are stored; these are usually called maternal reserves. Obese women are advised to limit weight gain to 5 to 9 kg (11 to 20 lb). Underweight women are advised to gain 12. 7 to18. 1 kg (28 to 40 lb) Weight may decrease slightly during the first trimester because of nausea, vomiting, and food intolerances of early pregnancy.
