The dangers of endometriosis include: first, causing blockage of the fallopian tubes. When a woman has endometriosis, it can lead to posterior uterine adhesions, which can cause adhesions in the fallopian tubes as well. At this time, the peristalsis of the fallopian tubes will be weakened and blockage of the fallopian tubes will occur. The obstructed fallopian tubes prevent the fertilized egg from reaching the uterus smoothly, so that the woman’s conception function is also affected. Second, it causes dysmenorrhea. Dysmenorrhea is not only a symptom of endometriosis, but also one of the hazards brought to women, mainly manifested as secondary dysmenorrhea. This kind of dysmenorrhea can last throughout the menstrual period, which is very painful for women and causes great impact on life and work. Third, it leads to infertility. If endometriosis occurs in the ovaries, the ovulation and secretion functions of the ovaries will not be able to function normally due to the cysts, which will lead to infertility and also bring a huge blow to women’s psychology. It is important to treat the disease promptly.
