📚 Understanding Pregnancy Weight Gain
Why Weight Gain Matters
Appropriate weight gain during pregnancy is crucial for both maternal and fetal health. It ensures adequate nutrition for baby's development and prepares your body for breastfeeding.
BMI-Based Guidelines
Weight gain recommendations are based on your pre-pregnancy BMI. Underweight women need more gain, while overweight women need less to maintain optimal health.
Consult Your Doctor
These are general guidelines. Always consult with your healthcare provider for personalized advice based on your individual health circumstances.
