How much weight should I gain during pregnancy?

Your healthcare professional helps you manage your weight throughout pregnancy. Your healthcare professional takes into account how much you weighed before pregnancy when helping you decide how much weight to gain.

Guidelines for pregnancy weight gain and obesity include the following:

• Single pregnancy. If you have a BMI of 30 or higher and are carrying one baby, the recommended weight gain is 11 to 20 pounds (about 5 to 9 kilograms).
• Multiple pregnancy. If you have a BMI of 30 or higher and are carrying twins or multiples, the recommended weight gain is 25 to 42 pounds (about 11 to 19 kilograms).

Your healthcare professional might not recommend that you gain a specific amount of weight during pregnancy. Instead, your healthcare professional might talk with you about preventing extra weight gain that could pose health risks.
