About Pregnancy Weight Gain

Healthy weight gain during pregnancy depends on your pre-pregnancy body mass index (BMI). Here are general guidelines from the Institute of Medicine:

• Underweight (BMI < 18.5): 12.5-18 kg (28-40 lbs)
• Normal weight (BMI 18.5-24.9): 11.5-16 kg (25-35 lbs)
• Overweight (BMI 25-29.9): 7-11.5 kg (15-25 lbs)
• Obese (BMI ≥ 30): 5-9 kg (11-20 lbs)

Always consult with your healthcare provider about your individual needs.
