Why is Weight Gain During Pregnancy Important?
Weight gain during pregnancy is not just about the growing baby. It supports the development of the placenta, amniotic fluid, and maternal tissues, and prepares the body for breastfeeding. However, gaining too much or too little weight can lead to complications for both the mother and the baby.
Key Reasons for Weight Gain:
- Fetal Development: Provides nutrients for the baby's growth.
- Maternal Health: Supports the mother's increased blood volume, uterus enlargement, and fat stores.
- Breastfeeding Preparation: Ensures adequate energy reserves for milk production.
