Pregnancy and Weight Gain

During pregnancy, your body goes through lots of changes to help give your baby a healthy start. Gaining weight during pregnancy is natural, normal, and healthy.

Gaining a healthy amount of weight:

  • Helps your baby grow and develop.
  • Helps lower the risk of health issues for you and your baby.
  • Helps your body make breastmilk.

How much weight should I gain?

The amount of weight gain that is right for you is based on your weight before you became pregnant. Weight gain is usually slow during your first trimester. Most of your weight gain will happen in your second and third trimesters.

Talk to your healthcare provider to discuss the recommended amount of weight you should gain during your pregnancy.

Eating well and being active can help you gain the amount of weight that is right for you and your developing baby.

  • Eat a little more food each day, such as an extra snack or a little more food at one of your meals. Although you are eating for two, you don’t need to eat twice as much.
