Comprehensive Guide to Pregnancy Weight Gain
Why Tracking Matters
Monitoring your weight gain during pregnancy is a vital part of prenatal care. Appropriate weight gain supports the growth of your baby and the changes in your body, preparing you for breastfeeding and motherhood.
Understanding the IOM Guidelines
The Institute of Medicine (IOM) updated its guidelines in 2009 to account for pre-pregnancy BMI (Body Mass Index).
Underweight (BMI < 18.5)
Target Gain: 12.5 - 18 kg (28-40 lbs)
Normal Weight (BMI 18.5 - 24.9)
Target Gain: 11.5 - 16 kg (25-35 lbs)
Overweight (BMI 25 - 29.9)
Target Gain: 7 - 11.5 kg (15-25 lbs)
Obese (BMI ≥ 30)
Target Gain: 5 - 9 kg (11-20 lbs)
Weight Gain by Trimester
First Trimester (Weeks 1-13)
Most women gain only a small amount of weight (0.5 to 2 kg) or none at all due to morning sickness.
Second Trimester (Weeks 14-27)
Your baby is growing rapidly. You should expect to gain about 0.5 kg (1 lb) per week if you started at a normal weight.
Third Trimester (Weeks 28-40)
Weight gain continues at a similar rate, but may slow down slightly near the end. Much of this weight is the baby itself.
Tips for Healthy Weight Gain
- Eat a balanced diet rich in whole grains, fruits, vegetables, and lean proteins.
- Stay hydrated by drinking plenty of water throughout the day.
- Engage in moderate physical activity like walking or swimming (with doctor's approval).
- Listen to your body's hunger and fullness cues.
- Avoid empty calories from sugary drinks and processed foods.
Frequently Asked Questions
What if I gain too much weight?

What if I don't gain enough?
Gaining too little can lead to a low birth weight for the baby or preterm birth. Your doctor can help check if your baby is growing well.
