Involution
The return of the uterus to its non-pregnant size and condition after delivery.
Full Definition
Uterine involution is the physiological process by which the uterus returns to its pre-pregnancy size, position, and condition following delivery. This process typically takes 6-8 weeks and involves contraction of uterine muscle fibers, reduction in blood supply, and elimination of excess tissue. The fundus can be palpated descending approximately 1 cm per day until it is no longer palpable above the pubic symphysis. Breastfeeding accelerates involution through oxytocin release. Delayed or incomplete involution may indicate retained placental fragments or infection.
Usage
Usage note: Specifically refers to uterine return to pre-pregnancy state.
