What are the causes of irregular menstrual bleeding?

Irregular vaginal bleeding refers to the phenomenon that, in addition to normal menstrual bleeding, it also manifests as heavy menstruation, prolonged menstruation, non-menstrual bleeding, contact bleeding, etc. When the bleeding is heavy, anemia may occur. In severe cases, it may cause exudative shock and seriously endanger life. Therefore, vaginal bleeding must be taken seriously and should not be treated blindly.

Causes of irregular vaginal bleeding

1. Cervical cancer: Cervical cancer can also cause bleeding, which starts as contact bleeding and then develops into a small amount of irregular vaginal bleeding, increased bleeding in the late stage, and even internal bleeding.

2. Abnormal uterine bleeding due to imbalance of function: occurs around puberty, childbearing age, and around menopause in women. The main manifestations are abnormalities in the menstrual cycle and menstrual period, and the bleeding may be more or less, intermittent, or even continuous.

3. Tumors inside the vagina and tumors on the vaginal wall: such as vaginal cancer, but generally with little bleeding. Vaginal injury and foreign objects in the vagina can also cause bleeding. The vaginal wall of postmenopausal women is too thin, and sexual intercourse can cause bleeding.

4. Foreign bodies in the uterine cavity: such as residual fetal membranes after cesarean section, which affect the contraction and repair of the uterine wall and cause bleeding. The reflex compression of the contraceptive ring can cause partial damage, necrosis and superficial ulcers of the uterine wall, resulting in bleeding. Endometriosis and adenomyosis may also cause bleeding.

5. Uterine perfusion disease: Subacute endometritis causes hematoma and edema of the uterine wall, which may lead to excessive menstrual flow or continuous vaginal bleeding in severe cases. Patients with chronic endometritis experience increased menstrual volume or prolonged menstrual duration, or non-menstrual bleeding in the vagina. In addition, tuberculosis of the uterine wall also causes irregular vaginal bleeding.

6. Bleeding during pregnancy: various types of miscarriage, such as threatened miscarriage, inevitable miscarriage, incomplete miscarriage, retained miscarriage, and habitual miscarriage. Incomplete delivery of the embryo during normal delivery, or residual embryonic tissue after abortion. Ectopic pregnancy often occurs in women aged 18 to 45. Hydatidiform mole, malignant hydatidiform mole and choriocarcinoma.
