Uterine fibroids are the most common benign tumors of the female genital canal. Most patients with fibroids have no obvious symptoms or signs and are only found incidentally during physical examinations. For those who have symptoms, the symptoms are related to the size, location and degeneration of fibroids. The main symptoms are as follows: 1. Increased menstrual flow and prolonged periods: the most common symptoms. If patients have increased menstrual flow and prolonged periods for a long time, it may lead to anemia, followed by weakness, palpitations and other anemia symptoms. If the myoma is accompanied by infection and necrosis, irregular vaginal bleeding or bloody purulent discharge may also occur. 2. Lower abdominal mass: When the fibroids are small, they are not palpable in the abdomen. When the fibroids increase to a certain extent and the uterus exceeds the pelvis, hard masses can be palpated in the lower abdomen. Huge submucosal fibroids can come out of the vagina, and patients often visit the doctor because of the masses coming out of the vagina. 3.Increased leucorrhea: Myomas located between the uterine walls can increase the area of the uterine cavity and increase the secretion of the uterine glands with pelvic congestion, resulting in increased leucorrhea. If combined with infection and necrosis, there may be bloody or pus-blood vaginal discharge. 4, compression symptoms: the front of the uterus is the bladder, the back is the rectum, when the uterine fibroids are larger, the uterus can press the bladder forward, causing frequent and urgent urination, pressing the rectum causes lower abdominal swelling, constipation, pressing the ureter can cause ureteral dilatation and even hydronephrosis. 5, abdominal pain: the outermost layer of the uterus is the plasma membrane layer, and acute abdominal pain can occur when acute torsion of the subplasma membrane myoma occurs. In patients with uterine fibroids during pregnancy or puerperium, red degeneration of fibroids is likely to occur, which is a special type of necrosis of fibroids and can be accompanied by severe abdominal pain with nausea, vomiting and fever when degeneration occurs. Some fibroids lose their original traits, and lower abdominal pain can occur when degeneration occurs. 6, infertility or miscarriage: fibroids located in the submucosa or other locations can cause infertility or miscarriage when they lead to deformation of the uterine cavity. In conclusion, the symptoms of fibroids vary depending on the location and size of fibroids.
