Menstruation that does not leave for a month belongs to prolonged menstruation, which may be caused by endometriosis, adenomyosis, endometritis and other diseases.
1. Endometriosis: this disease exists in the theory of planting and body cavity epithelialization, which may be related to abnormal immune function, heredity, inflammatory stimulation, environment and other factors. Some patients may have menstrual abnormalities such as increased menstrual blood flow, prolonged menstrual period and irregular menstrual flow, as well as symptoms such as dysmenorrhea, acute abdominal pain and pain during sexual intercourse.
2. Adenomyosis: The cause of this disease is not yet clear, and it may be related to heredity, hyperestrogenemia, endometritis, uterine operation and other reasons. Common symptoms include increased menstrual flow, prolonged menstrual period, dysmenorrhea, chronic pelvic pain, etc., but some patients have no typical symptoms.
3. Endometritis: The occurrence of this disease is mainly related to pathogenic microbial infections, such as chlamydia, mycoplasma, anaerobic bacteria, etc., which can be transmitted through blood circulation, lymphatic system spread and other ways. If the disease develops during menstruation, symptoms such as prolonged menstruation and increased menstrual flow will occur.
There are more reasons why menstruation does not leave for a month, so you need to go to the hospital and have a relevant examination to clarify the original disease.
