Menopausal women with increasingly severe dysmenorrhea are considered to be related to endometriosis, adenomyosis, and chronic pelvic inflammatory disease. 1. Endometriosis: If the functional endometriosis reaches the uterine cavity and parts of the uterus other than the myometrium, the endometrium will bleed with the cyclic changes of the ovaries, which will stimulate the local nerves and cause dysmenorrhea, which will be aggravated progressively, and the local lesions can be detected through the ultrasonography and pelvic MRI. 2. Adenomyosis: If the functional endometrium is ectopic to the myometrium, it will form limited or diffuse lesions, and the patient will have dysmenorrhea and lower abdominal pain due to the stimulation of the ectopic endometrium and the increase of the uterine volume. 3. Chronic Pelvic Inflammatory Disease: For patients with chronic pelvic inflammatory disease, the pelvic tissue congestion and edema during menstruation, and the body’s immune system is relatively poor, which may lead to an acute attack of chronic pelvic inflammatory disease and the emergence of lower abdominal pain, fever and other discomforts. For menopausal women, if menstrual cramps become more and more serious, it is recommended to go to the gynecology department of a regular hospital, complete the ultrasound and other relevant examinations, to clarify the cause of the disease, and then under the guidance of the doctor to actively treat.
