Most women wonder how much weight they should gain during pregnancy. The recommended weight gain is between 25 and 35 pounds. The exact amount will depend on your weight before pregnancy and other factors that your health care provider will discuss with you. Wherever your starting weight stands, you should not go on a diet, nor should you overeat. Too little or too much weight gain can lead to problems for both you and the baby in the months ahead.
Most providers recommend gaining 3 to 5 pounds in the first three months of pregnancy. For the rest of your pregnancy, most recommend gaining 1 to 2 pounds per week. Women who start out overweight should gain less, and women who start out underweight should gain more.
Keep in mind that most of the weight that you gain during pregnancy is baby-related (not fat). The weight is made up of the baby, the placenta, amniotic fluid, and the fluid that accumulates in your body tissues. About half of that weight will melt away in the first 6 weeks after your baby is born. You'll loose the rest by about 6 months after you deliver.
