What causes blood on tissue after urinating during late pregnancy?

Bleeding on toilet paper after urination during late pregnancy may cause concern for many expectant mothers. In fact, this could be due to reasons such as urine contamination, threatened preterm labor, or placenta previa. To ensure the safety of both mother and baby, it is recommended that pregnant women seek medical attention promptly, clarify the cause, and receive appropriate treatment.

1. Non-pathological Factors: Sometimes, this phenomenon may be caused by urine contamination. If personal hygiene is neglected during pregnancy, the vagina may be susceptible to bacterial infections, which may lead to localized mucosal rupture and bleeding. In such cases, no special treatment is usually required, and maintaining cleanliness and hygiene of the external genitalia and changing underwear frequently are sufficient.

2. Pathological Factors: Threatened preterm labor is a possible cause. Excessive fetal size or overdistension of the uterus may induce threatened preterm labor. In this situation, pregnant women may experience abdominal pain and have slight vaginal bleeding. Doctors may recommend medications such as dexamethasone injection to promote cervical ripening or, if necessary, terminate the pregnancy through cesarean section.

3. Placenta Previa: If a pregnant woman has a history of multiple miscarriages or curettage, it may affect the normal implantation of the fertilized egg, leading to placenta previa. In this case, pregnant women may experience painless recurrent vaginal bleeding without any apparent cause, accompanied by abdominal pain. As the condition progresses, they may also experience lumbar discomfort. Regular follow-up B-ultrasound examinations can help assess the condition, and cesarean section may be considered to alleviate symptoms if necessary.

Apart from the aforementioned causes, placental abruption and urinary tract stones may also cause similar symptoms. Once pregnant women notice bleeding on toilet paper after urination, they should promptly visit a reputable hospital so that doctors can diagnose and treat the condition based on specific circumstances. In late pregnancy, such symptoms should never be taken lightly. Prompt medical attention can not only help identify the cause but also provide necessary protection for both mother and baby. Maintaining good personal hygiene habits and regular prenatal checkups are important measures to ensure health during pregnancy. We hope all expectant mothers have a smooth pregnancy and welcome a healthy new life.
