What are the effects of uterine fibroids on menstruation?

When the size of fibroids growing under the uterine mucosa and between the uterine muscle walls gradually increases, the surface area of ​​the endometrium will increase, resulting in increased menstrual flow. In addition, when the fibroids gradually grow and cause ischemia, they will also cause prolonged menstrual cycles and irregular menstruation due to secondary degeneration. If it affects uterine contraction, anemia will occur due to excessive menstrual flow, resulting in a series of complications, and anemia will affect the menstrual flow, thus creating a vicious cycle.

Uterine fibroids are composed of uterine smooth muscle and its connective tissue, and are mostly caused by abnormal progesterone and estrogen. The most typical symptoms of this disease are periodic bleeding, as well as abdominal masses and compression symptoms. Because uterine fibroids are closely related to hormones, the menstruation of patients with uterine fibroids will be greatly affected. So what are the effects of uterine fibroids on menstruation?
1. The impact of uterine fibroids on menstruation
1. Causes menorrhagia <br/>When uterine fibroids grow between the muscle wall and under the mucosa, they will increase the area of ​​the uterine cavity, which will directly increase the surface area of ​​the endometrium. When the endometrium is shed during menstruation, it will cause an increase in menstrual blood volume. In addition, as uterine fibroids grow, if they compress the blood vessels in that area, venous return may be blocked, which will also cause an increase in menstrual volume.
2. Impact on the menstrual cycle <br/>The formation of uterine fibroids is directly related to the estrogen content in the body. If the estrogen level in the body continues to increase, it will promote the growth of fibroids, which will make the ischemia more serious. When the ischemia is serious, the secondary degeneration will increase, which will indirectly lead to irregular menstruation and delayed menstrual cycle.
3. Induce anemia <br/>After suffering from uterine fibroids, the uterus will contract uncoordinatedly, such as weak contractions. When the uterus contracts insufficiently, the menstrual volume will increase, and anemia will also occur. At this time, the patient will experience fatigue, pale lips, yellow face, dizziness and other discomfort symptoms. If the anemia persists, it will lead to a decrease in related coagulation factors, which will further lead to an increase in menstrual blood volume, and finally a vicious cycle.
2. Which uterine fibroids will not affect menstruation <br/>Some patients have uterine fibroids that grow in the myometrium. If they are not large and do not increase the endometrial area, they will not affect menstruation in most cases. In addition, if the fibroids grow outside the uterus, they will not affect the amount and cycle of menstruation. Therefore, whether uterine fibroids will affect menstruation is directly related to the size and location of the fibroids.
