What is the recommended total weight gain during pregnancy for a person with a normal pre-pregnancy BMI (18.5–24.9)?

• A. 25–35 pounds
• B. 15–25 pounds
• C. 35–45 pounds
• D. 5–15 pounds

Answer: (A)

Gaining an appropriate total amount of weight during pregnancy depends on what you start with before pregnancy. For someone with a normal pre-pregnancy BMI (about 18.5 to 24.9), the recommended total weight gain is 25 to 35 pounds. This range helps support the baby’s growth and the body's changes without adding excessive maternal risk.

Think of it in with-pace terms: in the first trimester, modest gain (roughly 1–4 pounds) is common, then in the rest of pregnancy about 0.8–1 pound per week is typical. Gains much lower than this can raise the risk of fetal growth restriction, while gains much higher can increase risks like gestational diabetes, hypertension, and delivering a larger baby.

Why the other ranges don’t fit: 15–25 pounds is often associated with overweight categories, where a lower gain is advised; 35–45 pounds exceeds the normal recommendation for a healthy pregnancy with a normal BMI and can raise complication risks; 5–15 pounds is generally too little for a normal BMI and may not provide enough nutrient stores for both mother and baby.
