Why is leucorrhea brown

Brown leucorrhea may be related to factors such as ovulatory bleeding, residual menstruation, vaginitis, cervical lesions, endometriosis and other factors. Brown leucorrhea is usually a manifestation of old mixed blood secretions, and the specific cause needs to be determined based on the accompanying symptoms.

1. Bleeding during ovulation

A brief drop in estrogen levels during ovulation may cause a small amount of endometrium to shed, causing the blood to turn brown after oxidation, often accompanied by mild abdominal pain or clear, stringy leucorrhea. This situation does not require special treatment, just keep the vulva clean. If the bleeding is heavy or lasts for more than 3 days, it is recommended to seek medical advice to rule out other causes.

2. Residues before and after menstruation

1-2 days before the onset of menstruation or 1-3 days after the end of menstruation, the slow discharge of residual menstrual blood in the uterine cavity may cause the leucorrhea to turn brown, but there is usually no other discomfort. Observe the regularity of the cycle in daily life and avoid strenuous exercise. If brown discharge lasts for more than 5 days or is accompanied by a peculiar smell, you need to be alert to gynecological inflammation.

3. Vaginitis

Bacterial vaginosis or trichomonas vaginitis may cause mucosal congestion and bleeding, resulting in brown discharge, often accompanied by itching, odor or burning sensation. Metronidazole vaginal suppositories, clotrimazole vaginal tablets or lactobacilli vaginal capsules can be used to regulate the bacterial flora as directed by your doctor. During treatment, avoid sexual intercourse and change underwear frequently.

4. Cervical lesions

Cervical erosion, cervical polyps or HPV infection may cause contact bleeding. The blood will turn brown when mixed with leucorrhea, and symptoms may worsen after sexual intercourse. The diagnosis needs to be confirmed through gynecological examination and TCT screening. If necessary, Baofukang suppository, interferon suppository or cervical electrocautery can be used for treatment.

5. Endometriosis

Periodic bleeding from endometriosis lesions may cause brown discharge, which is often accompanied by dysmenorrhea, dyspareunia or infertility. The diagnosis requires a combination of B-ultrasound and CA125 examination, and drugs such as dienogest tablets and drospirenone ethinylestradiol tablets can be used for treatment. In severe cases, laparoscopic surgery is required to remove the lesions.

It is recommended to choose cotton breathable underwear for daily use and avoid using irritating lotions to clean the perineum. If brown leucorrhea recurs or is accompanied by abdominal pain, fever and other symptoms, a gynecological examination should be carried out in time, including routine leucorrhea, ultrasound and cervical cancer screening. Avoid self-medication to delay the condition, especially women who are preparing for pregnancy or perimenopausal need to pay more attention to abnormal secretion changes.
