Understanding Pregnancy BMI Categories
BMI plays a major role in determining healthy pregnancy weight gain recommendations.

This is considered the standard recommended range.
Overweight
BMI between 25 and 29.9
Recommended total pregnancy weight gain:
- Approximately 7 to 11.5 kg
Weight gain recommendations are lower to minimize pregnancy complications.
Obese
BMI of 30 or higher
Recommended total pregnancy weight gain:
- Approximately 5 to 9 kg
Careful monitoring may be recommended by healthcare professionals.
