-
Uterine Involution After Delivery:
- After childbirth, the uterus undergoes a process called involution, where it gradually shrinks back to its pre-pregnancy size and position.
- This process is primarily completed by 6 weeks postpartum, though slight additional changes may occur later.
-
Timeline of Uterine Involution:
- Immediately after delivery: The uterus is at the level of the umbilicus.
- End of the first week: The uterus is midway between the umbilicus and the pubic symphysis.
- 2 weeks postpartum: The uterus is no longer palpable abdominally.
- 6 weeks postpartum: The uterus has returned to its non-pregnant size and weight (~50–70 g).
