Introduction
Menstruation that starts but does not stop—commonly referred to as prolonged or persistent menstrual bleeding—may result from non-disease factors, but can also be associated with certain medical conditions such as dysfunctional uterine bleeding or endometrial polyps. It is also important to evaluate possible links to polycystic ovary syndrome (PCOS), uterine fibroids, and other conditions. If prolonged menstruation is observed, it is recommended to seek prompt evaluation at a hospital gynecology department. Once the underlying cause is identified, treatment should be directed accordingly.
Menstruation that starts but does not stop typically refers to prolonged or persistent menstrual bleeding. This may be caused by non-disease factors, or it could be related to certain medical conditions such as dysfunctional uterine bleeding or endometrial polyps. It is recommended to identify the underlying cause and receive targeted treatment accordingly. The specific analysis is as follows:
I. Non-disease factors
During the initial stages of menstruation (menarche), ovarian development is not yet fully mature, which may result in longer menstrual periods. As age increases and the ovaries mature, the menstrual cycle usually becomes more regular. During the perimenopausal period, declining ovarian function can lead to hormonal imbalances and affect menstruation. Close observation is advised, and medical evaluation at a hospital should be considered if necessary.
II. Disease-related factors
1. Dysfunctional uterine bleeding
This condition is caused by ovulatory disorders and commonly occurs during adolescence or the perimenopausal period. Some women may have luteal phase deficiency after ovulation, leading to irregular menstrual cycles and prolonged bleeding. Treatment under medical guidance may include tranexamic acid tablets, drospirenone-ethinyl estradiol tablets, or ethinylestradiol-cyproterone acetate tablets.
2. Endometrial polyps
These are associated with chronic inflammation or pathogen infection. The mucosal tissue on the surface of the polyp is fragile and prone to bleeding upon contact, which may cause prolonged menstrual bleeding. If symptoms are significant, hysteroscopic polypectomy may be considered. After surgery, medications such as medroxyprogesterone acetate tablets, levonorgestrel tablets, or gestrinone capsules may be prescribed to prevent polyp recurrence.
In addition, it's important to evaluate whether other conditions such as polycystic ovary syndrome (PCOS) or uterine fibroids may be contributing. Once prolonged menstruation is noticed, early consultation with a gynecologist is recommended to determine the cause and initiate appropriate treatment.
