What Is Average Baby Weight Gain?

During pregnancy, your body gains weight to support the growth of your baby and the development of your organs. The average weight gain during pregnancy is about 25 to 35 pounds (11 to 16 kilograms) for women with a normal BMI before pregnancy.

The Institute of Medicine (IOM) recommends a weight gain of 25 to 35 pounds (11 to 16 kilograms) for women with a BMI of 18.5 to 24.9 before pregnancy. For women with a BMI below 18.5, the recommended weight gain is 28 to 40 pounds (13 to 18 kilograms).

Weight gain varies depending on factors such as your pre-pregnancy weight, height, and overall health. It's important to monitor your weight gain and consult with your healthcare provider if you have concerns.

Activity level: Regular exercise can help you maintain a healthy weight gain.
Medical conditions: Certain health conditions may affect weight gain.
Multiple pregnancies: Twins or higher-order pregnancies may result in more significant weight gain.

Consulting with your healthcare provider can help you understand how these factors may impact your pregnancy.
