What are uterine muscle wall nodules?

Many people may not know what uterine muscle wall nodules are. Here we must remind everyone that uterine muscle wall nodules generally indicate uterine fibroids. Therefore, when uterine muscle wall nodules are found, it is recommended to do further examination and diagnosis so as to provide early treatment. In order to make everyone more clear about what uterine muscle wall nodules are, we will introduce to you the causes of uterine muscle wall nodules, that is, the causes and symptoms of uterine fibroids.

Uterine fibroids are the most common benign tumors in the female reproductive organs and one of the most common tumors in the human body. They are also called fibroids and uterine fibroids. Since uterine fibroids are mainly formed by the proliferation of uterine smooth muscle cells, with a small amount of fibrous connective tissue existing as a supporting tissue, it is more accurate to call them uterine leiomyomas. Referred to as uterine fibroids.

The etiology of uterine fibroids is still unclear and may involve complex interactions among normal myometrial cell mutations, sex hormones, and local growth factors.

A large number of clinical observations and experimental results indicate that uterine fibroids are a hormone-dependent tumor. Estrogen is the main factor that promotes the growth of fibroids. Some scholars also believe that growth hormone (GH) is also related to the growth of fibroids. GH can cooperate with estrogen to promote mitosis and promote the growth of fibroids. It is speculated that human placental lactogen (HPL) can also cooperate with estrogen to promote mitosis. It is believed that the accelerated growth of uterine fibroids during pregnancy is related to the high hormone environment during pregnancy, and HPL may also play a role.

In addition, ovarian function and hormone metabolism are controlled and regulated by higher nerve centers, so the activity of nerve centers may also play an important role in the occurrence of fibroids. Uterine fibroids are more common in women of childbearing age, widows, and those with disharmonious sexual lives. Chronic pelvic congestion caused by long-term sexual dysfunction may also be one of the causes of uterine fibroids.

In short, the occurrence and development of uterine fibroids may be the result of the combined action of multiple factors.

Most patients are asymptomatic and the disease is only discovered occasionally during pelvic examination or ultrasound. If there are symptoms, they are closely related to the location, speed, degeneration and complications of the tumor growth, but have relatively little to do with the size and number of the tumor. People with multiple subserosal fibroids may not have symptoms, but a small submucosal fibroid can often cause irregular vaginal bleeding or menorrhagia. Common clinical symptoms include:

(1) Uterine bleeding is the most common symptom of uterine fibroids, occurring in more than half of patients.

(2) Abdominal masses and compression symptoms When the fibroids gradually grow and cause the uterus to enlarge to more than the size of a 3-month pregnant uterus or become a large subserosal fibroid located at the fundus of the uterus, a mass can often be felt in the abdomen, which is more obvious in the early morning when the bladder is full.

(3) Pain: Uterine fibroids generally do not cause pain, but many patients may complain of a feeling of heaviness in the lower abdomen and pain in the waist and back.

(4) Increased leucorrhea. Enlargement of the uterine cavity, increase in endometrial glands, and pelvic congestion can cause increased leucorrhea.

(5) Infertility and miscarriage

(6) Anemia: Long-term menorrhagia or irregular vaginal bleeding may cause hemorrhagic anemia. More severe anemia is more common in patients with submucosal fibroids.

(7) A very small number of patients with uterine fibroids may develop polycythemia and hypoglycemia, which are generally believed to be related to the production of ectopic hormones by the tumor.

Based on the above information, I believe everyone has a basic understanding of what uterine muscle wall nodules are. Therefore, when uterine muscle wall nodules appear, it is best to do further examination to confirm the diagnosis. Although uterine fibroids are a benign tumor, the symptoms they cause can still cause certain harm to patients.
