What causes uncontrolled fluid leakage in the late stages of pregnancy, and what should be done about it?
Generally, uncontrolled fluid leakage in the late stages of pregnancy may be caused by labor onset, urinary incontinence, vaginitis, cervicitis, or endometriosis, and improvements can be made according to the specific condition. It is recommended to seek timely medical attention and receive treatment under the guidance of a doctor. Detailed analysis is as follows:

1. Labor Onset
In the late stages of pregnancy, as the fetus develops, the cervix gradually dilates, leading to increased vaginal discharge that may manifest as uncontrolled fluid leakage. This is usually a normal phenomenon, and it is advised to go to the hospital promptly for delivery preparation.
2. Urinary Incontinence
As the fetus grows in late pregnancy, the uterus enlarges and exerts significant pressure on the bladder. When a pregnant woman coughs, laughs loudly, sneezes, or changes posture, abdominal pressure further increases, causing urine to leak uncontrollably from the bladder. Pregnant women can perform pelvic floor muscle exercises, such as Kegel exercises—contracting the pelvic floor muscles—to strengthen these muscles and improve urinary control.
3. Vaginitis
Poor personal hygiene during pregnancy may lead to vaginitis, resulting in increased vaginal discharge and exudation, which can cause fluid leakage from the vagina. Patients can use medications such as clotrimazole suppositories, Sophora flavescens gel, or Honglu Fuyan cleansing solution under medical supervision.
4. Cervicitis
Cervicitis refers to inflammation of the cervical vaginal portion and cervical canal mucosa, often associated with pathogen infection or vaginal flora imbalance. Symptoms may include increased vaginal discharge and external genital itching, presenting as abnormal fluid loss in late pregnancy. Patients may follow medical advice to take medications such as amoxicillin capsules, Gongyanping tablets, or azithromycin capsules. Adequate rest is also recommended.
5. Endometriosis
During pregnancy, immune system changes may allow endometrial tissue to invade the uterine muscle layer, causing endometriosis and subsequent abnormal bleeding. In late pregnancy, this abnormal bleeding may present as uncontrolled fluid leakage. Patients may follow medical instructions to use medications such as danazol capsules, gestrinone capsules, or norethisterone tablets to relieve symptoms.
Pregnant women should maintain healthy lifestyle habits during pregnancy and avoid consuming spicy and irritating foods such as Sichuan pepper, chili peppers, and garlic to prevent adverse health effects.
