Sudden bleeding usually refers to sudden vaginal bleeding. Sudden vaginal bleeding half a month after childbirth is considered to be related to factors such as poor uterine involution, residual tissue in the uterine cavity, uterine cavity infection, and uterine fibroids. Targeted treatment measures need to be taken to prevent the condition from progressing. Here are some possible causes and corresponding treatments:

1. Poor Uterine Involution

During childbirth, the contractility of the uterus may decrease. If it fails to fully recover, symptoms of persistent vaginal bleeding may occur. Massage can be used to determine the contraction of the uterus. Additionally, medications such as Yimucao Granules, Xinshenghua Granules, and Guizhi Fuling Capsules can be prescribed by a doctor to promote uterine recovery.

2. Residual Tissue in the Uterine Cavity

If residual tissue in the uterine cavity is not completely expelled, it may also lead to sudden vaginal bleeding after childbirth, often accompanied by increased vaginal discharge and lower abdominal pain. Curettage may be required to reduce damage to the endometrium and avoid affecting recovery. It is also important to maintain good personal hygiene and regularly clean the external genital area.

3. Uterine Cavity Infection

Improper care after childbirth may lead to the invasion of pathogens into the uterine cavity, increasing the risk of infection. Common symptoms include lower abdominal discomfort, fever, and pain. Medications such as Moxifloxacin Hydrochloride Tablets, Doxycycline Hydrochloride Enteric-coated Capsules, and Amoxicillin Capsules can be prescribed by a doctor to treat the infection and provide antibacterial effects. It is also important to keep the abdomen warm to avoid hypothermia.

4. Uterine Fibroids

Patients with uterine fibroids may experience certain damage to the endometrium after childbirth, leading to persistent bleeding and potentially causing the fibroids to continue to grow. Medications such as Triptorelin Acetate for Injection, Leuprolide Acetate Microspheres for Injection, and Mifepristone Tablets can be prescribed by a doctor to manage the condition. Surgical removal of the fibroids may be necessary in severe cases. Additionally, uterine malformations may also contribute to sudden vaginal bleeding half a month after childbirth, potentially affecting physiological regularity. Surgical correction of the uterus may be required in such cases.

If significant discomfort or symptoms are present, it is important to seek medical attention promptly.
