Functional uterine bleeding is a disease caused by hormonal imbalances in women. Most cases of functional uterine bleeding are not serious, but being not serious does not mean it can be ignored. Generally, when a woman experiences functional uterine bleeding, it is recommended to immediately seek medical attention at the gynecology outpatient clinic of a local hospital, undergo a gynecological color ultrasound, sex hormone panel, and other relevant examinations. Identify the causes and types of functional uterine bleeding, and adopt different treatment plans based on different results. Meanwhile, it is important to note that if the bleeding is heavy, it may be necessary to perform a blood cell examination to determine whether anemia has occurred.
