There are various reasons for patients to have brownish leukorrhea without pain or itching, the first one is ovulation. Usually, when a patient is ovulating, the leukorrhea can be partially blood-stained, resulting in a brownish appearance, which is a normal physiological phenomenon. In addition, it is not excluded that it is caused by childbirth or miscarriage, IUD stimulation, cervicitis, endometrial polyps, tumors, etc.: 1. Childbirth or miscarriage: Patients who have just given birth or miscarried have bleeding in the vagina, causing the leucorrhea to take on a brownish form, and usually without painful itching. Generally, the symptoms will disappear on their own as the patient’s body recovers. If the bleeding symptoms do not ease, the patient needs to go to the hospital for hemostasis and anti-inflammatory treatment. 2. IUD stimulation: If the patient has an intrauterine device placed in the uterus, the patient may have brownish leucorrhea around the time of her period, and there is no obvious discomfort. This is mainly caused by the fact that the IUD will inhibit the contraction of the uterus, thus causing uterine bleeding. After the end of menstruation, most patients’ brownish leucorrhea symptoms will disappear on their own; 3. Cervicitis: mainly due to the inflammatory reaction of the cervix triggered by infection, patients often have abnormal leucorrhea, abnormal vaginal bleeding and other symptoms, there is a possibility of brownish leucorrhea. At this time, it is recommended that patients go to the hospital in a timely manner, under the guidance of the doctor using antibiotics such as minocycline, azithromycin, clarithromycin, erythromycin treatment, but also laser, freezing, microwave treatment; 4, endometrial polyps: high estrogen levels, inflammatory stimulation, etc. may induce endometrial polyps, often accompanied by clinical manifestations of abnormal uterine bleeding. When the blood flows from the vagina, brownish leucorrhea appears. Treatment requires progesterone to relieve the bleeding symptoms as prescribed by the doctor, and progesterone has the effect of shrinking uterine polyps to some extent. In addition, hysteroscopic polyp removal or scraping surgery can also be used for treatment; 5, gynecological malignancies: cervical cancer, endometrial cancer, etc. under the influence of the patient’s vagina will appear bleeding symptoms, usually affect the leucorrhea, resulting in brownish leucorrhea. Once diagnosed with gynecological malignant tumor, patients should go to hospital for surgical treatment such as conical hysterectomy, radical hysterectomy, as well as with radiotherapy and chemotherapy in a timely manner.
