The bleeding caused by celiac disease after pregnancy is characterized mostly by a small amount of vaginal bleeding. Celiac disease is a normal change in the morphology and physiology of the cervix, which is actually an ectropion of the cervical columnar epithelium, and is caused by changes in the hormonal levels in a woman’s body. Because of the increase in estrogen and progesterone in a woman’s body after pregnancy, it can lead to an increase in the symptoms of cervical erosion, which can easily cause vaginal bleeding. Usually, when a woman has celiac disease, the bleeding is mostly caused by a small amount of blood in the leukorrhea or a small amount of vaginal bleeding after sex. If the bleeding is not taken seriously, it can easily cause inflammation of the cervix or vagina, which can lead to other diseases in the long run. Women are avoiding sex after pregnancy, so the bleeding is mostly caused by the increase of estrogen level in the body. This kind of bleeding is not much, different from the bleeding caused by miscarriage, and the mechanism by which it occurs is different, and it does not affect the development of the fetus. However, it is important to stop the bleeding in time, and if necessary, hospital visits are made to give symptomatic treatment. Celiac disease pregnancy bleeding is not very heavy, the bleeding does not last too long and the color is very similar to the color of our menstruation. Therefore, if you have vaginal bleeding after pregnancy, go to the hospital in time to find out the cause, except for cervical polyps. TCT and HPV can also be done during pregnancy to determine if the bleeding is caused by cervical erosion or cervical lesions, and give symptomatic treatment.
