What is the common duration for postpartum vaginal blood loss as excess tissue is shed?

The duration of postpartum vaginal blood loss, often referred to as lochia, typically ranges from 4 to 6 weeks. This process occurs as the uterus returns to its pre-pregnancy size and excess tissue, including placenta remnants, is shed.

During the initial days after delivery, lochia can be quite heavy and may include bright red blood as the body begins to cleanse itself. Over the following weeks, the blood loss decreases in both volume and changes in color, transitioning to a more yellowish or white discharge. The 4 to 6-week timeline reflects not only the physical changes occurring in the uterus but also the body's healing processes.

While some women may experience a shorter or longer duration of lochia, the majority fall within this 4 to 6-week range, making it a clinically relevant and important timeframe for monitoring postpartum recovery.
