The primary consideration should be inadequate uterine contraction postpartum. Secondarily, hormonal imbalances should be ruled out. A multifaceted approach to treatment is advisable. Recommendations: Undergo a color Doppler ultrasound to check for abnormalities in the uterus and adnexa. If normal, treat with hemostatic agents and antibiotics. Additionally, washing your hair is permissible, but bathing is not allowed.
After childbirth, the shedding of the uterine decidua—particularly the decidua attached to the placenta—results in vaginal discharge containing blood, necrotic decidual tissue, and other substances, known as lochia. Typically, lochia clears within three weeks postpartum. Persistent spotting beyond this period is termed "prolonged lochia."The classical Chinese medical text "Essentials of Fetal and Childbirth Care" states: "Due to injury to the blood vessels during childbirth, deficiency and insufficiency arise, preventing proper consolidation. Alternatively, if lochia is not fully expelled, fresh blood cannot settle, and both types flow together, persisting without cessation over time." Thus, persistent lochia is often associated with "deficiency" or "blood stasis."
Postpartum, as the uterine lining (especially where the placenta attached) sheds, mucus secreted by the uterus is expelled through the vagina—this constitutes lochia. Normal lochia has a faint bloody odor but is not foul-smelling, with a total volume of approximately 500–1000 milliliters. Typically, lochia subsides around three weeks postpartum.
