Intrauterine fluid-like changes refer to the symptom of fluid collection in the uterine cavity detected by ultrasound prompting. There are many reasons for the accumulation of fluid in the uterine cavity. If the patient has undergone abortion or medical abortion that causes blood accumulation in the uterine cavity, she needs to take medicines such as motherwort to promote the discharge of the blood. If the bleeding is caused by poor embryonic development and unstable implantation during pregnancy, the patient should go to the hospital to have her hormone levels tested before deciding on the treatment plan. If the patient is suffering from endometritis or uterine adhesions that cause inflammatory effusion in the uterus, a gynecological examination is needed to confirm the diagnosis. If the patient has fluid in the uterine cavity after menstruation or after menopause, diagnostic scraping or hysteroscopic surgery is needed to rule out endometrial abnormalities, endometrial cancer and other diseases. It is recommended to consult a medical professional for advice.
