After a cesarean section, how many days does lochia last after uterine clearance?

Patient's question:

No

Doctor's answer:

Hello: After a cesarean section, lochia usually stops within three weeks. It is recommended to do an ultrasound for diagnosis. For poor uterine contraction, you can take Motherwort ointment. Pay attention to the hygiene of the perineum after surgery, and avoid spicy and irritating foods.
