What are the causes of irregular vaginal bleeding?

In daily life, the reason for vaginal bleeding in women is generally menstruation, which is a normal physiological phenomenon. However, there are also some other vaginal problems such as irregular bleeding, heavy menstrual flow or prolonged menstruation, which make women very worried. So, what are the causes of irregular vaginal bleeding? Let’s take a closer look below.

1. Cervical tumor: Cervical cancer can also cause bleeding, which starts as contact bleeding and then develops into a small amount of irregular vaginal bleeding. In the late stage, the amount of bleeding increases, and even heavy bleeding may occur.

2. Dysfunctional uterine bleeding: occurs before and after puberty, during childbearing years, and before and after menopause. It manifests as abnormalities in the menstrual cycle and menstrual period, with bleeding that may be more or less, sometimes absent, or even continuous.

3. Vaginal tumors and vaginal wall tumors: such as vaginal cancer, but the amount of bleeding is generally not much. Vaginal injury and foreign objects in the vagina can also cause bleeding. The vaginal walls of postmenopausal women are very thin, and damage from sexual intercourse can lead to bleeding.

4. Foreign bodies in the uterine cavity: such as residual fetal membranes after cesarean section, which affect the contraction and repair of the endometrium and cause bleeding. Mechanical compression of the intrauterine device can cause local damage, necrosis and superficial ulcers in the endometrium, leading to bleeding. Endometriosis and adenomyosis may also cause bleeding.

5. Uterine lesions: Acute endometritis causes congestion and edema of the endometrium. In severe cases, it may lead to excessive menstrual flow or continuous vaginal bleeding. Patients with chronic endometritis may experience increased menstrual flow or prolonged menstrual periods, or irregular vaginal bleeding. In addition, endometrial tuberculosis also causes irregular vaginal bleeding.

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

The above is an introduction to the causes of irregular vaginal bleeding. I hope it will be helpful to everyone’s understanding. There are many reasons for irregular vaginal bleeding in women, and it is also a common occurrence. In daily life, once such symptoms are found, women should pay enough attention, actively look for the cause, and then solve it in a targeted manner to avoid greater harm.
