What are the conditions for vaginal bleeding?

After sexual intercourse, there is bleeding in the female genitals. At this time, many people think that this is a relatively normal thing. They really don’t know what kind of disease is behind vaginal bleeding. Regarding vaginal bleeding, many people regard it as a small and relatively normal situation. Then let us introduce several situations about vaginal bleeding?

Vaginal bleeding related to pregnancy

Vaginal bleeding related to pregnancy is common with miscarriage. Most of the embryos in early abortions are dead, and the basal decidua is necrotic and hemorrhaged, causing the embryo's villi to detach from the decidua and the blood sinuses to open and bleed. Before 8 weeks of pregnancy, the chorionic villi are not yet mature and the connection with the uterine decidua is not yet firm. The entire blastocyst can easily be completely separated from the uterine wall, and there is often not much bleeding. During the 8th to 12th week of pregnancy, the chorionic villi are vigorously developed and deeply embedded in the uterine membrane, with a firm connection. The placenta villi are not completely separated and cannot be expelled at the same time as the fetus. Some placental tissue remains in the uterine cavity, affecting uterine contraction and causing severe bleeding. Late miscarriage, such as retained membranes or placenta, can also result in heavy bleeding.

Tumor-related bleeding

1. Uterine fibroids Uterine fibroids are a common cause of vaginal bleeding. ① Patients with fibroids often suffer from endometrial hyperplasia and polyps due to excessive estrogen, leading to excessive menstrual flow; ② Fibroids cause the uterus to increase in size, the endometrial area to increase, and the amount of bleeding is excessive or the bleeding lasts too long. Especially in the case of submembranous fibroids, the area of ​​the uterus increases and bleeding increases; ③ In the case of submembranous fibroids, the surface of the membrane often ulcerates and necrotizes, leading to chronic endometritis and causing continuous bleeding; ④ Intramural fibroids affect uterine contraction and the effect of clamping blood vessels, or the endometrium of submembranous fibroids cannot contract itself, all of which lead to excessive bleeding and prolonged bleeding time; ⑤ Larger fibroids may be combined with pelvic congestion, making the blood flow vigorous and large in amount.

2. The second is vaginal bleeding caused by cervical cancer and endometrial cancer. Cervical cancer bleeding is mainly seen in the exophytic type, also known as the cauliflower type, which is brittle and often causes contact bleeding. Later, as the tumor grows and tissue necrosis and shedding occur, heavy bleeding occurs. In endometrial cancer, the endometrium presents as polyp-like protrusions that are enlarged, hard, and brittle, with superficial ulcers on the surface. In the late stage of the disease, there are ulcers and necrosis, involving the entire endometrium, and the necrotic tissue sheds and bleeds in small to moderate amounts or continuously.

Bleeding associated with inflammation and trauma

Many women do not take protective measures when they experience discomfort such as vulvar itching, which allows harmful bacteria to grow and aggravates the problem. Genital tract inflammation can cause congestion, erosion or ulcers in the vulva and lead to bleeding, which is usually in small amounts. Violent trauma and irritation of the new membrane of the reproductive tract by foreign bodies and subsequent infection can cause vaginal bleeding.

Bleeding related to systemic illness

Abnormalities in platelet quantity and quality, coagulation and anticoagulation dysfunction including thrombocytopenic purpura, severe liver disease, and disseminated intravascular coagulation can all cause vaginal bleeding.

The above introduces several common situations of vaginal bleeding. When you see such situations, do you think that it is normal for such things to happen? Is such a thing a minor matter? Dear female friends, when you encounter bleeding after sexual intercourse, we must seek medical attention in time.
