What is a persistent lochia duration that requires evaluation?

Lochia refers to the vaginal discharge that occurs after childbirth, which is composed of blood, mucus, and uterine tissue. The duration and characteristics of lochia can vary among individuals, but typically, it is expected to occur for approximately 4 to 6 weeks postpartum, with gradual changes in its nature from lochia rubra (red) to lochia serosa (pink) and finally to lochia alba (white/yellowish).

A duration of 8 weeks for lochia is concerning and suggests the need for evaluation. Extended lochia beyond this timeframe may indicate underlying issues such as retained placental fragments, infection, or other complications that require medical attention. Thus, 8 weeks is a significant threshold because it surpasses the normal range, raising the possibility of complications that necessitate further investigation and potential intervention to ensure the health of the individual. Evaluating patients who present with persistent lochia after this period is important for preventing complications associated with prolonged postpartum recovery.
