What is the normal range of weight gain during pregnancy?
The normal range of weight gain during pregnancy varies based on a woman's starting weight, but generally ranges from 25 to 35 pounds for those with a normal BMI before pregnancy.
Explanation
Weight gain during pregnancy is important for a healthy baby and mom. The amount of weight you should gain depends on your body mass index (BMI) before you got pregnant.
- Normal BMI (18.5 - 24.9): Gain about 25 to 35 pounds.
- Underweight BMI (less than 18.5): Gain about 28 to 40 pounds.
- Overweight BMI (25 - 29.9): Gain about 15 to 25 pounds.
- Obese BMI (30 or more): Gain about 11 to 20 pounds.
These guidelines help ensure the baby grows well and helps avoid complications. It's important to talk to your doctor about what's best for you, as every pregnancy is unique.
