Weight Gain in Pregnancy

During pregnancy it is important to use healthy lifestyle habits to control your pregnancy weight gain, support your baby's health and make it easier to shed the extra pounds after delivery.

Pregnancy weight gain guidelines

The amount of weight you need to gain depends on various factors, including your pre-pregnancy weight, and you and your baby’s health. We will monitor you weight and work with you on your weight gain if you have any concerns or health reasons that require it. These are some general guidelines for weight gain in pregnancy.

Overweight guidelines

Being overweight before and during your pregnancy increases the risk of various pregnancy complications, including gestational diabetes, high blood pressure and preterm birth. Although a certain amount of pregnancy weight gain is ok, it is considered safe to not gain as much as if you were ideal body weight. Typically a recommended weight gain is around 15 pounds. If you gain more than the recommended amount during pregnancy and you don't lose the weight after the baby is born, the excess pounds increase your lifelong health risks. Gaining too much weight during pregnancy can also increase your baby's risk of health problems at birth and during childhood.

Underweight guidelines

If you're underweight, it's essential to gain a reasonable amount of weight while you're pregnant. Without proper weight gain your baby’s health may be effected from poor growth or preterm birth.

Where do I gain the weight?

  • Baby: 6 to 8 pounds (about 3 kilograms)
  • Larger breasts: 2 pounds (about 1 kilogram)
  • Larger uterus: 2 pounds (about 1 kilogram)
  • Placenta: 2 pounds (about 1 kilogram)
  • Amniotic fluid: 2 pounds (about 1 kilogram)

What is the average weight gain?

In the first trimester, most women don't need to gain much weight — which is good news if you're struggling with morning sickness. It is most important to stay well hydrated. Weight gain is more important in the second and third trimesters. This often means gaining about 1 pound a week until delivery. This is about 300 calories a day if you are starting out at a normal weight, which is about a half a sandwich and an 8 oz glass of skim milk extra a day. If you start out underweight you may want to add more calories to your diet.

What foods to add?

It is better to eat healthy and maintain weight, than it is to each non-healthy foods (junk food) to gain weight.

  • Trade white bread and pasta for the whole-grain variety.
  • Increase protein in your diet with foods such as lean meats.
  • Choose a salad with low-fat dressing.
  • Eat whole fruit instead of snack foods or baked goods.
  • Limit fruit juices due to concentrated calories
