How long does lochia last after a cesarean delivery?
After a cesarean delivery, lochia—the postpartum vaginal discharge composed of blood, mucus, and uterine tissue—typically persists for about 4 to 6 weeks. This duration is similar to that observed after vaginal delivery, as lochia reflects the physiological process of uterine involution and endometrial healing, not the mode of delivery itself. Lochia generally progresses through three distinct stages: lochia rubra (bright red, blood-rich discharge lasting 3–5 days), lochia serosa (pinkish-brown, thinner discharge lasting approximately days 5–10), and lochia alba (whitish-yellow, mostly leukocyte- and mucus-rich discharge lasting up to week 6). While mild spotting or intermittent light discharge may occasionally occur beyond 6 weeks, persistent, heavy, foul-smelling, or bright red bleeding after this period warrants prompt clinical evaluation to rule out complications such as retained placental tissue, endometritis, or uterine atony.
