It is typical for women to have leukorrhea after pregnancy. Usually, after pregnancy, there is a significant increase in leukorrhea. However, if leucorrhea continues to increase, it is likely to be caused by endocrine disorders and should be seen by a hospital immediately. The reason is that as the months of pregnancy increase, the estrogen in the body gradually increases, and estrogen can promote the secretion of leucorrhea, resulting in increased leucorrhea. At the same time, the blood flow in the vagina and cervix of pregnant women is stronger and water increases after pregnancy, so the secretion increases and so does the leucorrhea. Although leucorrhea increases in early pregnancy, if it suddenly increases in large amounts and the color and state of the leucorrhea are abnormal, then there may be some kind of gynecological inflammation that needs to be checked and treated at the hospital. It is recommended to have regular checkups after pregnancy to keep abreast of the development of the fetus and the physical changes of the pregnant woman. In addition, pregnant women should change their underwear and underpants every day in a timely manner to keep them clean and avoid causing urinary tract infections as well as inflammation and other diseases.
