At the age of 52, if you have a period that never clears, you should pay high attention to it. If there is thickening of the endometrium, uneven echogenicity of the endometrium, or abnormal massing of the endometrium, diagnostic scraping should be done in a timely manner and the scraped tissue should be sent for pathological examination to rule out the possibility of organic endometrial lesions. A routine blood test and coagulation time test are also needed to find out if the dysmenorrhea is caused by thrombocytopenia or abnormal coagulation time. The majority of women enter the perimenopause at the age of 52, when the hormone level in the body is basically disordered, so some functional uterine bleeding may occur clinically, but organic lesions must be excluded before medication can be given.
