Normal menstrual cycle is 2-7 days, if the menstrual cycle is more than 7 days, it is not normal. Longer menstrual period may be caused by endocrine disorders, endometrial inflammation, endometrial polyps or submucosal fibroids, or systemic diseases.
1. Endocrine disorders: endocrine disorders can be caused by excessive stress at work and study, excessive dieting, poor sleep, obesity, etc. Women with endocrine disorders will experience menstrual disorders, and some of them will show prolonged menstrual periods.
2. Endometrial inflammation: endometrial inflammation during menstruation is difficult to repair the lining of the uterus, so there will be the symptom of prolonged menstruation, but usually the amount of menstruation is small.
3. Endometrial polyps or submucosal fibroids: endometrial polyps and submucosal fibroids can also lead to longer periods, because polyps and submucosal fibroids can lead to poor contraction of the uterus, resulting in prolonged menstruation.
4. Systemic diseases: Some systemic diseases, such as leukemia, can cause abnormal blood clotting function, which can lead to prolonged menstruation.
If menstruation takes more than 7 days, you should go to the hospital for further examination and treatment under doctor’s guidance.
