What should a foul odor from lochia indicate?

A foul odor from lochia is a significant clinical finding that can indicate a possible infection. Lochia refers to the vaginal discharge that occurs after childbirth as the uterus heals and sheds its lining. The normal discharge is usually comprised of blood, mucus, and uterine tissues, and it typically has a mild odor. When there is a noticeable foul smell, it suggests that there may be an infectious process occurring, such as endometritis, which is an infection of the uterine lining.

Prompt identification of a foul odor is crucial, as infections can lead to more severe complications if not addressed quickly. In contrast, a normal healing process, pelvic organ descent, or typical postpartum discharge would not present with an unpleasant odor. Therefore, recognizing a foul odor is important for ensuring appropriate medical attention is taken to safeguard the mother's health.
