Menstruation is generally referred to as menstruation, and a month-long absence of menstruation may be caused by pregnancy-related diseases, luteal insufficiency, or uterine-related diseases.
1. Pregnancy-related diseases: If the menstruation is normal, the occurrence of menstruation for a month may be caused by abnormal pregnancy, such as ectopic pregnancy, spontaneous abortion, incomplete abortion, preeclampsia and other pregnancy-related diseases.
2. Luteal insufficiency: the uterine lining is shed during menstruation, and then the lining is slowly repaired. If the luteal insufficiency occurs, the endometrial repair function may decline, and menstruation does not leave for a month.
3. Uterus-related diseases: such as adenomyosis, fibroids and other diseases, when the endometrium is being repaired, the uterus can’t contract normally, and the blood sinuses are not easy to be closed, so there will be a situation that the menstruation comes for a month and doesn’t go away.
Under normal circumstances, menstruation for more than seven days is an abnormal phenomenon, so if you have menstruation for a month, you should go to the hospital in time to find out the cause of the disease, and under the guidance of the doctor to treat the symptoms.
