What causes blood streaks in vaginal discharge and lower abdominal pain?
Generally, bloody streaks in vaginal discharge and lower abdominal pain may be caused by mid-cycle bleeding, dysfunctional uterine bleeding, intrauterine devices, cervicitis, endometritis, and other factors, requiring different treatments depending on the specific situation.
1. Mid-Cycle Bleeding: During ovulation, estrogen levels in women temporarily decrease, causing partial shedding of the endometrium due to the lack of estrogen support, which may lead to slight vaginal bleeding that appears as blood-streaked vaginal discharge. Usually, no special treatment is required. It is recommended to maintain adequate rest, avoid excessive fatigue, and keep a positive mood.
2. Dysfunctional Uterine Bleeding: This is mainly caused by neuroendocrine disorders and commonly occurs in adolescent and perimenopausal women. During these stages, hormonal imbalances can lead to irregular menstrual cycles, increased menstrual flow, and prolonged menstruation, which may result in blood-streaked vaginal discharge. It is recommended to follow a physician's instructions for medications such as estradiol benzoate injection or dydrogesterone tablets to stop the bleeding and regulate the menstrual cycle.
3. Intrauterine Device (IUD): After insertion of an IUD, as a foreign body, it may irritate the endometrium, causing localized injury and inflammatory reactions, which can lead to light vaginal bleeding and blood-streaked vaginal discharge. If symptoms persist or worsen, it is recommended to take medications such as tranexamic acid tablets or cefuroxime axetil granules under medical supervision.
4. Cervicitis: Cervicitis is often caused by pathogenic infections. Inflammatory stimulation can cause congestion, swelling, and fragility of the cervical mucosa, which may lead to contact bleeding and blood-streaked vaginal discharge. It is recommended to follow a physician's guidance for treatment with medications such as ceftriaxone sodium for injection or spectinomycin hydrochloride for injection.
5. Endometritis: Bacteria may ascend from the vagina or cervix, spread via the fallopian tubes, or reach the endometrium through the lymphatic system, causing endometritis. Inflammation may lead to congestion and swelling of the endometrium; in severe cases, endometrial necrosis and shedding may occur, resulting in vaginal bleeding that appears as blood-streaked vaginal discharge. It is recommended to follow a physician's instructions for treatment with medications such as cefixime tablets or metronidazole tablets.
If blood-streaked vaginal discharge accompanied by persistent lower abdominal pain does not improve, it is recommended to seek timely medical attention for appropriate diagnostic tests to determine the underlying cause and implement corresponding treatment measures.
