Uterine involution
Uterine involution is the process by which your uterus shrinks back toward its pre-pregnancy size after you give birth. Right after delivery, your uterus weighs about 1 kilogram and sits at your belly button level. Over the next six weeks, it gradually contracts and returns to roughly 60 grams. This process is driven by hormones, particularly oxytocin, which is released naturally and also when you breastfeed. You may feel your uterus as a firm ball in your lower abdomen in the first days. If involution is slow, your doctor may recommend uterine massage or medication to help it along.
What This Means for You
Understanding Uterine involution is an important part of your after birth journey. Keeping this in mind as you read, attend appointments, and connect with other parents will help you feel more prepared and less overwhelmed.

Breastfeeding speeds up involution because it triggers oxytocin release. At your six-week postnatal check at KKH or NUH, your doctor will assess whether your uterus has returned to a normal size.
