Tubal failure may cause abdominal discomfort, dysmenorrhea, infertility and other symptoms. 1. Abdominal discomfort: If the fallopian tube is not working, there may be different degrees of pain in the abdomen, which is usually a hidden discomfort. As the disease progresses, the pain may spread to the lower back or sacral region, and there may also be swelling, aching or falling sensation. Tubal obstruction may also cause pelvic adhesions, resulting in painful filling of the bladder and rectum or painful reaction during emptying. 2. Dysmenorrhea: Tubal failure may cause dysmenorrhea. As women’s fallopian tubes are affected by chronic inflammation for a long time, it will trigger pelvic congestion, and most of them will have abdominal pain starting one week before menstruation, which may be slightly relieved until the onset of menstruation. 3. Infertility: Tubal impassability will make the mature egg discharged from the ovary unable to pass through the fallopian tube to meet with the sperm, and the sperm and egg can not be combined will lead to infertility. It is recommended that women should pay attention to the safety and hygiene of sex life, regular gynecological examination, and seek timely medical treatment to find out the specific causes of tubal impassability and active treatment.
