Pregnancy Weight Gain Recommendations
Gaining the recommended weight during pregnancy is essential to prevent pregnancy complications. The amount of weight gained during pregnancy can affect the immediate and future health of a woman and her infant.
Depending on how much a woman weighed before getting pregnant, the IOM recommended weight gain for each category of pre-pregnancy BMI in singleton pregnancies as follows:
- Underweight (< 18.5 kg/m2); total weight gain range: 28 to 40 pounds
- Normal weight (18.5 - 24.9 kg/m2); total weight gain range: 25 to 35 pounds
- Overweight (25.0 - 29.9 kg/m2); total weight gain range: 15 to 25 pounds
- Obese (≥ 30.0 kg/m2); total weight gain range: 11 to 20 pounds
What is the normal pregnancy weight gain?
Your pregnancy weight gain depends on how much you weigh when you start your pregnancy. One way to look at your weight is to weigh yourself in pounds (lb) or kilograms (kg). But then your height is also important, so calculating the body mass index (BMI) becomes important to know whether you are underweight, normal weight, overweight, or obese. You can calculate your BMI here.
For twin pregnancy, the IOM recommends a gestational weight gain of 16.8–24.5 kg (37–54 lb) for women of normal weight, 14.1–22.7 kg (31–50 lb) for overweight women, and 11.3–19.1 kg (25–42 lb) for obese women. The IOM guidelines recognize that data are insufficient to determine the amount of weight women with multifetal (triplet and higher order) gestations should gain.
