By about which days is the uterus usually no longer palpable due to involution?

• A. Day 5.
• B. Day 7.
• C. Day 9.
• D. Day 10–14.

Answer: (D)

Postpartum involution is the process by which the uterus returns to its pre-pregnant size after delivery as the placental site heals and the myometrium contracts. The fundus descends about 1 centimeter each day after birth. It’s typically palpable at the level of the umbilicus on the first day and then moves downward rapidly. By about 10 to 14 days after birth, the uterus is usually no longer palpable abdominally, reflecting that involution is complete. If it remains palpable longer or feels boggy, that could indicate delayed involution or a complication, but the usual teaching is that nonpalpability occurs around day 10–14.
