If the menstrual blood is pink, it is often due to the following reasons. The first is that inflammation of the endometrium leads to a large amount of exudation, which dilutes the menstrual blood to form a pink color, often accompanied by an increase in vaginal discharge and clinical symptoms of lower abdominal pain. Secondly, if the menstrual blood is pink, it is clinically likely to be caused by severe anemia. It is recommended to do routine blood tests to find out whether there is anemia. If it is caused by inflammation of the endometrium, it is recommended to actively give anti-inflammatory treatment, or antibiotics can be injected directly into the uterine cavity for treatment. In addition, intravenous antibiotics can also be used for treatment. If it is caused by anemia, it is important to understand the cause of the anemia in the clinic and then give treatment.
