Why Is There Always a Little Blood Down There?

Bleeding outside of menstrual periods in women should be taken seriously. Bleeding can also occur during ovulation, and this can be predicted based on a woman's menstrual cycle. If bleeding occurs at other times, and it is frequent, it could be a sign of an underlying medical condition. Many clinical conditions have similar characteristics, and it is important to determine the cause as soon as possible. So, what could be the reason for persistent slight bleeding?

Vaginal bleeding refers to bleeding from the reproductive system that is not part of a normal menstrual cycle. It is one of the more common symptoms of gynecological diseases. Bleeding can occur in the vagina, cervix, uterine body, and fallopian tubes, but uterine bleeding is the most common.

a. Dysfunction of ovarian endocrine function can lead to uterine bleeding. Additionally, a temporary decrease in estrogen levels due to follicular rupture during menstruation can also cause uterine bleeding.

b. Genital tumors, such as uterine fibroids, cervical cancer, and endometrial cancer, can all cause vaginal bleeding.

c. Bleeding related to pregnancy, such as ectopic pregnancy, threatened abortion, and miscarriage.

d. Inflammation and trauma of the reproductive organs can lead to vaginal bleeding.

e. Systemic diseases, such as abnormalities in the quantity and quality of platelets, coagulation disorders including thrombocytopenic purpura, aplastic anemia, liver dysfunction, can all cause vaginal bleeding.

f. Exogenous hormones, such as estrogen and progesterone medications, can cause "breakthrough bleeding" or "withdrawal bleeding".

a. In children, vaginal bleeding should be considered a possibility of sexual precocity or malignancy of the reproductive tract.

b. In adolescents, vaginal bleeding accompanied by pain in the vagina and vulva, along with varying amounts of fresh blood, may be caused by trauma.

c. In women of reproductive age, slight vaginal bleeding between menstrual cycles may be due to ovulation bleeding, which is normal.

d. Vaginal bleeding after menopause is common in women with ectopic pregnancy and miscarriage. This bleeding is often accompanied by lower abdominal discomfort and may persist for a long time. It should not be simply attributed to ovulation bleeding without confirming pregnancy.

e. Bleeding caused by contraceptives is known as breakthrough bleeding.

f. Vaginal bleeding after menopause for 2 years should be carefully evaluated to exclude malignant conditions such as cervical cancer and endometrial cancer. Other considerations include inflammation, polyps, and endocrine factors.

g. Incomplete uterine involution and puerperal infection can lead to bleeding. Incomplete involution of the uterine placental attachment surface can cause blood clot detachment and reopening of blood sinuses, resulting in uterine bleeding. Puerperal infection, most commonly endometritis, can lead to poor involution and poor uterine contraction of the uterine placental attachment surface, resulting in incomplete closure of blood sinuses and uterine bleeding.

h. Bleeding can also be caused by endometritis, myometritis, salpingitis, pelvic cellulitis, and other conditions.

i. Genital tumors such as uterine fibroids, cervical cancer, endometrial cancer, and ovarian cancer can also cause vaginal bleeding.
