There’s no one-size-fits-all approach to pregnancy weight gain.
How much weight you need to gain depends on various factors, including your pre-pregnancy weight and body mass index (BMI). Your health and your baby’s health also play a role. A healthy gain for most women is between 25 and 35 pounds. If you are overweight, you should gain less, but some weight gain is normal. If you are underweight, you should gain more. Talk with your doctor about the amount of weight you can expect to gain. This may vary if you are pregnant with more than one baby.
Consider these general guidelines for pregnancy weight gain:
- Normal weight -25-37 pounds if you were a healthy weight before pregnancy.
- Underweight -28-40 pounds if you were underweight before pregnancy.
- Overweight -15-25 pounds if you were overweight before pregnancy.
Pregnancy weight gain guidelines
|Pre-pregnancy weight||Recommended weight gain|
|Underweight (BMI less than 18.5)||28 to 40 pounds (about 13 to 18 kilograms)|
|Normal weight (BMI 18.5 to 24.9)||25 to 35 pounds (about 11 to 16 kilograms)|
|Overweight (BMI 25 to 29.9)||15 to 25 pounds (about 7 to 11 kilograms)|
|Obese (BMI 30 or greater)||11 to 20 pounds (about 5 to 9 kilograms)|
If you’re carrying twins or multiples, you’ll likely need to gain more weight. Again, work with your health care provider to determine what’s right for you.
