Introduction
In general, the causes of brown vaginal discharge may include menstruation, ovulation bleeding, endocrine disorders, cervicitis, endometritis, etc. The solution depends on the specific cause and requires prompt medical consultation and treatment as directed by a physician. Before the onset of menstruation, hormone levels in a woman's body change, especially with a decrease in estrogen and progesterone levels.

Generally, the causes of brown vaginal discharge include menstruation, ovulation bleeding, hormonal imbalance, cervicitis, and endometritis. The appropriate solution depends on the specific cause, and medical advice should be sought promptly for treatment. Details are as follows:

1. Menstruation: Before the onset of menstruation, hormonal levels in women's bodies, especially estrogen and progesterone, decrease. This may cause slight shedding of the endometrium, which mixes with vaginal discharge and appears brown. Women are advised to keep warm, avoid excessive fatigue, maintain a pleasant mood, and wait for menstruation to begin.

2. Ovulation Bleeding: During ovulation, estrogen levels temporarily decline, which may cause partial shedding of the endometrium due to lack of hormonal support, resulting in minor vaginal bleeding. This blood mixes with vaginal discharge, forming brown discharge. This is generally a normal physiological phenomenon and typically requires no special treatment.

3. Hormonal Imbalance: Hormonal imbalance refers to abnormal hormonal changes in women's bodies. These changes may cause irregular shedding of the endometrium or abnormal bleeding, resulting in brown vaginal discharge, which may also be accompanied by irregular menstruation. Treatment may include medications such as Modified Xiaoyao Pills, Estradiol Valerate Tablets, or Dydrogesterone Tablets, under a doctor's guidance.

4. Cervicitis: Cervicitis is an inflammation of the cervix and cervical canal mucosa. The inflammation may cause congestion, swelling, erosion, and bleeding of the cervical mucosa, leading to brown vaginal discharge, which may also be accompanied by lower abdominal pain. Under a doctor's guidance, medications such as Azithromycin Capsules, Doxycycline Hydrochloride Enteric-coated Capsules, or Minocycline Hydrochloride Capsules may be used to eliminate the pathogen.

5. Endometritis: Endometritis is an inflammation of the endometrium. The inflammation may cause congestion, swelling, necrosis, and bleeding of the endometrium, leading to brown vaginal discharge, which may also be accompanied by fever. Treatment may include medications such as Roxithromycin Capsules, Cefuroxime Axetil Granules, or Levofloxacin Tablets, under medical guidance, to reduce inflammation.

Maintaining good lifestyle habits and a positive mindset in daily life can help prevent and manage brown vaginal discharge.
