What should I do if there is a foul odor in lochia after a cesarean section?

After a cesarean section, if the mother notices an unusual odor in her lochia, this may indicate an infection and medical attention should be sought promptly. Lochia is a mixture of tissue from the uterine lining, blood, and bacteria that shed after childbirth. Under normal circumstances, the color of lochia changes gradually from bright red to light red, and finally turns white or yellow, without a noticeable odor. If foul-smelling lochia occurs, it may suggest a bacterial infection, such as endometritis or other genital tract infections. The abnormal odor may be related to various factors including improper diet, retained products in the uterine cavity, poor uterine involution, endometritis, or vaginitis. A systematic examination is necessary to determine the exact cause.

Based on the underlying cause, pelvic examination, collection of secretion samples for bacterial culture and sensitivity testing are recommended. Treatment may involve the use of antibacterial agents, antifungal medications, oxytocic drugs, or antibiotics. Additionally, the mother should maintain good personal hygiene, frequently change sanitary pads, avoid wearing tight-fitting clothing, and keep the external genital area dry. Drinking plenty of water, maintaining a balanced diet, and engaging in appropriate physical activity can also aid in recovery.
