Lochia after cesarean section sometimes occurs and sometimes does not occur

Lochia is a type of blood clot containing harmful substances that is discharged from the body after childbirth. Generally, the human body will have this kind of lochia after a cesarean section. However, there are many abnormal conditions of lochia. For example, lochia may appear and disappear after a cesarean section. This situation should be taken seriously, but many people do not know the specific reasons for it. So why does lochia appear and disappear after a cesarean section?

Postpartum lochia refers to the discharge through the vagina of tissues such as blood and necrotic decidua that is shed along with the uterine decidua. It is called lochia. It is a clinical manifestation of the parturient in the puerperium and is a physiological change. Lochia has a bloody smell but no odor. Its color and contents change over time. It usually lasts for 4 to 6 weeks and the total amount is 250ml to 500ml. If a lot of lochia is still discharged after the above time, it is called postpartum lochia retention.

Normal lochia is divided into three types according to its color, contents and time:

Lochia sanguinaria: It is named because it contains a large amount of blood. It is bright red in color, large in amount, and sometimes contains small blood clots. Microscopically, a large number of red blood cells, necrotic decidua and a small amount of fetal membranes were seen. Bloody lochia lasts for 3 to 4 days. The bleeding gradually decreases, the serous fluid increases, and turns into serous lochia.

Serous lochia: It is named because it contains a large amount of serous fluid and is light red in color. Microscopically, there are a lot of necrotic decidual tissues, intrauterine exudate, cervical mucus, a small amount of red blood cells and white blood cells, and bacteria. Serous lochia lasts for about 10 days, the serous fluid gradually decreases, the white blood cells increase, and it turns into white lochia.

White lochia: It is named because it contains a large number of white blood cells and is white in color and has a viscous texture. Under the microscope, a large number of white blood cells, necrotic decidual tissue, epidermal cells and bacteria were seen. The white lochia lasts for about 3 weeks.

Although every parturient has lochia, the amount discharged is different for each person, and the average total amount can reach 500 to 1000 ml. The duration of discharge varies from woman to woman. Normal women usually need 2 to 4 weeks, while a few women can last 1 to 2 months.
