Track recommended weight gain during pregnancy based on your pre-pregnancy BMI and current week.
The Institute of Medicine (IOM) provides weight gain recommendations based on pre-pregnancy BMI. Gaining within the recommended range is associated with the best outcomes for both mother and baby.
It depends on pre-pregnancy BMI. Underweight: 12.5-18 kg. Normal weight: 11.5-16 kg. Overweight: 7-11.5 kg. Obese: 5-9 kg. These are IOM guidelines for single pregnancies.
