Bloody discharge usually lasts for about 3-4 days, after which it gradually decreases while the plasma gradually increases, thus changing to plasma discharge. After delivery, the necrotic shedding of meconium mixed with blood is discharged from the vagina, which is known as bad diarrhea. Postpartum discharge can be classified into bloody, plasma and white discharge according to the color and content. Hemorrhagic discharge mainly occurs within 3 days after delivery, and its content contains a large amount of blood, bright red in color and large in quantity. If the bloody discharge increases or lasts for a long period of time, it is considered that the uterus is not recovering well, and the patient is advised to give medication to promote uterine contraction under the guidance of the doctor, and at the same time, it can prevent late postpartum hemorrhage. If there is an obvious odor and pus discharge, the possibility of puerperal infection cannot be ruled out. In addition, during the period of discharge, it is recommended that mothers pay attention to personal hygiene and avoid spicy and stimulating foods to prevent infection.
