What causes light menstrual flow six months after childbirth?

Reduced menstrual flow six months after childbirth may be caused by factors such as incomplete recovery of endocrine function, breastfeeding effects, endometritis, polycystic ovary syndrome (PCOS), or intrauterine adhesions. This condition can be improved through lifestyle adjustments, medication, or intrauterine treatments. If menstrual flow remains consistently low or is accompanied by abdominal pain, prompt medical consultation is necessary.

1. Incomplete Endocrine Recovery: After childbirth, ovarian function may not have fully recovered, leading to hormonal imbalances and insufficient endometrial proliferation, which results in reduced menstrual flow. It is recommended to maintain regular sleep patterns, avoid staying up late, eat a balanced diet rich in nutrients, and support the restoration of normal endocrine function.

2. Breastfeeding Effects: During lactation, elevated levels of prolactin in the body suppress ovulation and hormone secretion, leading to decreased menstrual flow or even temporary amenorrhea. Continued breastfeeding is recommended without excessive intervention, as menstruation typically resumes naturally after weaning.

3. Endometritis: Bacterial infection of the uterine lining postpartum can cause inflammation that damages endometrial tissue, resulting in reduced menstrual flow along with mild lower abdominal pain and increased vaginal discharge. It is recommended to take medications such as cefixime dispersible tablets, metronidazole tablets, and Gynecological Qianjin tablets under medical guidance to alleviate symptoms.

4. Polycystic Ovary Syndrome (PCOS): Hormonal disturbances after childbirth may trigger PCOS, causing abnormal ovulation and elevated androgen levels, leading to reduced menstrual flow, prolonged cycles, hirsutism, and obesity. Medications such as ethinylestradiol cyproterone acetate tablets, drospirenone-ethinyl estradiol tablets, and metformin hydrochloride tablets may be used under medical supervision to manage symptoms.

5. Intrauterine Adhesions: Trauma to the endometrium from postpartum uterine procedures may lead to adhesions within the uterine cavity, obstructing menstrual blood flow and causing reduced menstruation; severe cases may involve dysmenorrhea. Treatment may include medications such as estradiol valerate tablets, progesterone capsules, and enteric-coated aspirin tablets as directed by a physician.

Daily care should include maintaining external genital hygiene, changing underwear regularly, and avoiding excessive fatigue. Maintaining a positive mood and engaging in moderate exercise can promote blood circulation. A balanced diet rich in protein and vitamins is also recommended.
