What causes vaginal bleeding after intercourse a few days before menstruation, and what should be done?
Bleeding after intercourse a few days before menstruation may be caused by physiological factors or pathological conditions such as cervicitis or cervical polyps, which require targeted treatment. The specific analysis is as follows:
I. Physiological Factors
A few days before menstruation, the endometrium is in a relatively fragile state. Intercourse at this time may trigger uterine contractions, leading to partial shedding of the endometrium and resulting in bleeding after intercourse. This is a normal physiological phenomenon and generally does not require excessive concern.
II. Pathological Factors
1. Cervicitis
Long-term unhygienic sexual activity may induce cervicitis. Inflammatory factors can irritate the cervix, and hormonal fluctuations a few days before menstruation may intensify this irritation, causing postcoital bleeding. Treatment under medical guidance may include medications such as metronidazole suppositories or tinidazole suppositories.
2. Cervical Polyps
Chronic inflammation may lead to local hyperplasia of cervical tissue, forming cervical polyps. During intercourse, increased abdominal pressure can stimulate these polyps and cause bleeding. Surgical removal at a hospital is recommended.
In addition to the above, other conditions such as vaginitis, endometritis, and adenomyosis may also cause bleeding after intercourse a few days before menstruation. It is advisable to seek timely medical evaluation to avoid delaying optimal treatment.
