Can I have miscarriage if I get pregnant with uterine fibroids?

Uterine fibroids can affect a woman's fertility. In other words, after suffering from uterine fibroids, a woman's fertility will be affected and infertility is very likely to occur. Of course, this is not absolute. There are also women who become pregnant during the illness. So will pregnancy with uterine fibroids cause miscarriage? Studies have shown that compared to normal pregnancy, the chance of miscarriage in pregnancies with uterine fibroids is very high.

Is it easy to have miscarriage in the second trimester due to uterine fibroids?

If the fibroids compress the fallopian tubes, it will affect the activity of sperm, the movement of sperm and eggs, and eventually cause infertility. Once pregnancy is possible, the fibroids will grow rapidly as the uterus grows, especially after the second trimester, and undergo "degeneration", causing symptoms such as abdominal pain and fever. Uterine fibroids can sometimes easily cause miscarriage and premature birth. Here, experts point out that uterine fibroids can be treated with abortion, which generally will not affect women's physical health, but it is still necessary to go to a regular hospital for a comprehensive examination and then proceed according to the doctor's advice. This is the safest method.

What are uterine fibroids

Uterine myoma is the most common benign tumor of the female reproductive organ and is composed of smooth muscle and connective tissue. It is common in women aged 30 to 50 and rare in women under 20 years old. Uterine fibroids can be divided into benign and malignant types. The most common benign tumors are uterine leiomyoma, and the malignant tumors are endometrial cancer and uterine sarcoma. According to autopsy statistics, about 20% of women over 30 years old have uterine fibroids. Because most fibroids have no or very few symptoms, the reported clinical incidence rate is much lower than the actual incidence rate of fibroids. The vast majority of uterine fibroids are benign. However, since uterine fibroids tend to occur multiple times, in women of childbearing age, fibroids may gradually increase in size and number as they age, and myoma removal surgery may also result in recurrence. The malignant transformation rate of uterine fibroids is very low, about 0.4-0.8%. But we still need to be vigilant about the risk of malignant transformation. Uterine fibroids can usually be divided into subserosal fibroids, intramural fibroids, submucosal fibroids or cervical fibroids, broad ligament fibroids, etc. Different types of uterine fibroids may show clinical manifestations such as menorrhagia, lower abdominal mass, or difficulty urinating or defecation.

Symptoms of uterine fibroids

(1) Increased menstrual flow and prolonged menstrual period: These are the most common symptoms of uterine fibroids. It is more common in large intramural fibroids and submucosal fibroids. Fibroids enlarge the uterine cavity, increase the area of ​​the endometrium and affect uterine contraction. In addition, fibroids may compress the veins near the tumor, causing congestion and dilation of the endometrial venous plexus, thereby causing increased menstrual flow and prolonged menstruation. When submucosal fibroids are accompanied by necrosis and infection, there may be irregular vaginal bleeding or bloody purulent discharge. Long-term excessive menstrual flow may lead to anemia, fatigue, palpitations and other symptoms.

(2) Lower abdominal mass: When the fibroids are small, the mass cannot be felt in the abdomen. When the fibroids gradually increase in size and the uterus exceeds the size of a 3-month pregnancy, it can be felt from the abdomen. Giant submucosal fibroids can prolapse outside the vagina, and patients may seek medical attention due to prolapse of the vulva.

(3) Increased vaginal discharge: Intramural fibroids increase the area of ​​the uterine cavity, increase the secretion of endometrial glands, and are accompanied by pelvic congestion, resulting in increased vaginal discharge. Once submucosal fibroids are infected, there may be a large amount of purulent vaginal discharge. If there is ulceration, necrosis, or bleeding, there may be bloody or purulent vaginal discharge with a foul odor.

(4) Compression symptoms: Myomas in the lower segment of the anterior uterine wall can compress the bladder and cause frequent and urgent urination; myomas in the cervix can cause dysuria and urinary retention; myomas in the posterior uterine wall (isthmus or posterior wall) can cause symptoms such as lower abdominal distension and constipation. Broad ligament myomas or giant cervical myomas develop laterally, embed into the pelvic cavity, compress the ureter, and cause obstruction of the upper urinary tract, resulting in ureteral dilatation and even hydronephrosis.

(5) Others: including lower abdominal distension, back pain, and worsening symptoms during menstruation. When the fibroids turn red, there will be acute lower abdominal pain, accompanied by vomiting, fever and local tenderness of the tumor; torsion of the pedicle of subserosal fibroids may cause acute abdominal pain; abdominal pain may also be caused when submucosal fibroids are discharged from the uterine cavity. Torsion of the pedicle of submucosal fibroids may cause acute abdominal pain; abdominal pain may also be caused when submucosal fibroids are discharged from the uterine cavity. Submucosal and intramural fibroids that cause deformation of the uterine cavity can cause infertility or miscarriage.
