Pelvic endometriosis a common gynecological disorder, is a condition in which endometrial tissue, which should grow and shed normally in the uterine cavity, appears in other areas outside the uterine cavity and undergoes cyclic atrophy, necrosis, and shedding under hormonal influence, forming ectopic lesions. Pelvic endometriosis is often associated with defective immune defenses and genetics. If the patient has a defective immune function in the body, the endometrium that flows backwards into the abdominal cavity with menstrual blood is prone to develop into endometriosis. In addition, endometriosis has a genetic predisposition, so if the mother has the disease, her daughter is also susceptible to it. The disease is most common in women of childbearing age and is often associated with ovarian dysfunction, such as excessive menstruation and dysmenorrhea, which may be due to increased endometriosis and ectopic growth. It may also be accompanied by painful intercourse and anal swelling. Due to endometriosis, the tissues around the uterine rectal fossa, anus and other organs swell and cause pain. If there are often symptoms such as menstrual disorders and dysmenorrhea, it is recommended to go to the hospital for sex hormone diagnosis and ultrasound and other examinations in order to clarify the cause. Drug treatment is suitable for patients with chronic pelvic pain, obvious menstrual dysmenorrhea, fertility requirements and no ovarian cyst formation. For larger ovarian endometriosis cysts, especially those with ovarian masses of unknown nature, surgical treatment is appropriate. During menstruation, patients should pay attention to keeping the abdomen warm and use warm water bags for hot compresses to avoid getting cold. Avoid vigorous sports and heavy physical labor, and pay attention to rest.
