Frequently Asked Questions - Pregnancy Weight Gain
Weight gain depends on your pre-pregnancy BMI: Underweight (28-40 lbs), Normal weight (25-35 lbs), Overweight (15-25 lbs), and Obese (11-20 lbs). These ranges support healthy fetal development and maternal health.
Most weight gain occurs in the second and third trimesters. First trimester: 1-4 lbs total. Second and third trimesters: 1-2 lbs per week for normal weight women, adjusted based on pre-pregnancy BMI.
Multiple pregnancies require higher weight gain: Twins (normal BMI): 37-54 lbs, Twins (overweight): 31-50 lbs, Twins (obese): 25-42 lbs. Consult your doctor for personalized recommendations for triplets or higher-order multiples.
Too little weight gain can lead to low birth weight and preterm birth. Excessive weight gain increases risks of gestational diabetes, high blood pressure, large babies, delivery complications, and difficulty losing weight postpartum.
Focus on nutrient-dense foods, regular moderate exercise (with doctor approval), staying hydrated, eating regular meals, avoiding empty calories, and tracking weight weekly. Always consult your healthcare provider for personalized guidance.
