During which postpartum phase is lochia characterized by mostly blood?

The phase of lochia characterized primarily by blood is known as lochia rubra. This stage occurs immediately after childbirth and typically lasts for the first three to four days postpartum. During this time, the discharge contains red blood cells, decidual tissue, and mucus, which contributes to its bright red color.

Understanding lochia is crucial for monitoring a woman's recovery after childbirth. Lochia rubra signifies the body's process of shedding the uterine lining that was thickened during pregnancy, and the presence of bright red blood is a normal part of this healing process.

In contrast, other phases such as lochia serosa, which follows lochia rubra, consists of a pink or brownish discharge due to the gradual decrease in blood content and the presence of leukocytes and cervical mucus. Lochia alba follows lochia serosa and is characterized by a yellowish-white discharge, indicating further healing as the uterus continues to recover. The term "lochia pendula" does not refer to any recognized phase and may be a misunderstanding or a misnomer, making it an incorrect choice.
