In general, increased menstrual flow after childbirth may be related to factors such as uterine recovery, breastfeeding, endometritis, endometriosis, and uterine fibroids. If discomfort occurs, it is recommended to seek medical attention promptly and receive symptomatic treatment under a doctor's guidance. Specific analyses are as follows:

1. Uterine Recovery Process

After delivery, the uterus requires time to gradually return from its pregnant state to the non-pregnant state. The shedding and regeneration of the endometrium may lead to increased menstrual flow. In most cases, uterine recovery is a natural process that does not require special treatment.

2. Breastfeeding

During lactation, elevated levels of prolactin in the body may affect the menstrual cycle and volume. It is recommended to maintain good nutrition and rest, and ensure adequate fluid intake.

3. Endometritis

Endometritis is an inflammatory response caused by bacterial invasion of the endometrium. Inflammation may lead to endometrial congestion, edema, and increased exudate, thereby affecting normal endometrial shedding and repair, resulting in excessive menstrual bleeding. Symptoms may include abdominal pain, fever, and increased vaginal discharge. Under medical supervision, patients may be treated with antibiotics such as metronidazole tablets, clindamycin hydrochloride capsules, or amoxicillin granules.

4. Endometriosis

Displaced endometrial tissue may respond to hormonal changes and bleed monthly but cannot be discharged normally, potentially causing inflammation and increased menstrual flow. Symptoms may include dysmenorrhea and painful intercourse. Patients are advised to take medications such as danazol capsules, medroxyprogesterone acetate tablets, or norethisterone tablets under a doctor’s guidance.

5. Uterine Fibroids

Enlargement of uterine fibroids may increase uterine volume and interfere with normal endometrial shedding, leading to heavier menstrual bleeding. Symptoms may include lower abdominal pain, frequent urination, and constipation. Treatment may include medications such as guizhi fuling capsules, hongjin xiaojie capsules, or danbie capsules, taken as directed by a physician.

Postpartum women are advised to maintain healthy lifestyle habits, replenish necessary nutrients, and avoid fatigue, which may help alleviate symptoms.
