Introduction

In general, light bleeding four months postpartum may be caused by the resumption of menstruation, poor uterine involution, endocrine disorders, cervicitis, endometritis, or other conditions. If there are any uncomfortable symptoms, it is recommended to seek medical treatment at a hospital promptly. In daily life, postpartum women should maintain good hygiene, keep the genital area dry and clean, and avoid sexual intercourse to prevent the occurrence of inflammation.

Generally, light bleeding four months after childbirth may be caused by the resumption of menstruation, poor uterine involution, hormonal imbalances, cervicitis, or endometritis. If there are any discomfort symptoms, it is recommended to seek medical treatment promptly. Detailed explanations are as follows:

1. Resumption of Menstruation

In women who are not breastfeeding, menstruation usually resumes between 6 to 10 weeks postpartum, while in breastfeeding women, the return of menstruation is delayed. However, some women may resume menstruation around four months postpartum. Therefore, light bleeding four months after childbirth might indicate the onset of menstruation, often accompanied by a mild sensation of distension in the lower abdomen. Generally, no special treatment is required.

2. Poor Uterine Involution

After childbirth, the uterus needs to gradually return to its pre-pregnancy state. During this process, inadequate rest or excessive fatigue may cause symptoms of slight bleeding. It may also be accompanied by prolonged lochia, an unpleasant odor, or abdominal pain. Usually, no special treatment is required. Appropriate physical activity or gentle uterine massage can help expel lochia and shed tissue.

3. Hormonal Imbalance

After childbirth, a woman's hormone levels undergo significant changes, and the endocrine system may still be adjusting. Abnormal fluctuations in estrogen levels can cause irregular shedding of the endometrium, resulting in slight bleeding. This type of bleeding is usually irregular and may be accompanied by mood swings, hot flashes, and other symptoms. Treatment may include medications such as levothyroxine sodium tablets, progesterone soft capsules, and motherwort granules, under a doctor's guidance.

4. Cervicitis

After childbirth, a woman's immunity decreases, making the cervix susceptible to pathogenic infections, which can lead to cervicitis. Inflammatory irritation of the cervical mucosa may cause mucosal congestion and edema, potentially resulting in slight contact bleeding. Symptoms may also include increased vaginal discharge, purulent discharge, and an unpleasant odor. Treatment may involve medications such as anti-cervicitis tablets, cervicitis relief capsules, and metronidazole tablets, as directed by a physician.

5. Endometritis

Endometritis is an inflammation of the endometrium caused by pathogenic infection. Inflammatory factors can irritate the endometrium, causing congestion and edema. In severe cases, the endometrium may become necrotic and slough off, resulting in slight bleeding. Symptoms may also include fever, lower abdominal pain, and increased lochia. Treatment may involve medications such as clindamycin hydrochloride capsules, moxifloxacin hydrochloride tablets, and ornidazole capsules, as directed by a physician.

In daily life, postpartum women should maintain hygiene and keep the genital area dry and clean. Sexual intercourse should be avoided to prevent inflammation. Additionally, spicy and irritating foods should not be consumed, as they may increase bleeding and hinder recovery.

Does Chuanxiong promote lactation?

In general, whether Chuanxiong (Ligusticum chuanxiong) can be used to promote lactation needs to be determined based on the specific physical condition of the mother. The use of Chuanxiong for lactation promotion must be guided by a qualified traditional Chinese medicine practitioner, who will adjust the formula and dosage according to the mother's postpartum condition. It should not be self-administered without professional advice. If a postpartum mother experiences abnormal lactation, the underlying cause should first be identified to avoid blind medication use.
