Introduction
In general, if a pregnant woman experiences bleeding during bowel movements, it may be caused by constipation, hemorrhoids, colitis, anal polyps, threatened miscarriage, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Maintain adequate rest in daily life and avoid fatigue and strenuous exercise. Additionally, attend regular prenatal checkups at the hospital to monitor fetal development.
In general, if a pregnant woman experiences bleeding during bowel movements, it may be caused by constipation, hemorrhoids, colitis, anal polyps, threatened miscarriage, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified healthcare provider. Specific analyses are as follows:
1. Constipation
Irregular eating habits and frequent consumption of hard-to-digest foods can easily lead to constipation in pregnant women. Hard, dry stools may injure the intestinal mucosa during defecation, resulting in bleeding. Therefore, it is advisable to maintain healthy dietary habits, such as consuming more easily digestible foods like rice, noodles, vegetables, and fruits, which can help alleviate symptoms.
2. Hemorrhoids
As the uterus enlarges, pressure on the rectum increases, impeding venous blood return and potentially leading to hemorrhoidal masses. This may cause rupture of rectal blood vessels, resulting in rectal venous bleeding, often accompanied by symptoms such as anal itching and moisture. Under medical supervision, medications such as Dizhu Huaijiao Pills, Mahuang Pills, or Sanqi Huazhi Pills may be used for treatment.
3. Colitis
If a pregnant woman does not pay attention to food hygiene, gastrointestinal infections or colitis may occur, potentially causing bloody stools along with symptoms such as diarrhea and abdominal pain. Treatment may include medications like montmorillonite powder, enteritis relief tablets, or lactase tablets, taken as directed by a physician.
4. Anal Polyps
Anal polyps refer to pedunculated, raised lesions occurring on the rectal mucosa or anal canal. Bleeding during bowel movements in pregnant women may indicate such lesions, which may also be associated with changes in bowel habits or stool abnormalities. Warm saline sitz baths can help improve local circulation, reduce swelling, and relieve discomfort.
5. Threatened Miscarriage
Threatened miscarriage is usually caused by poor embryonic development or maternal factors. Increased intra-abdominal pressure during defecation may trigger vaginal bleeding, often accompanied by intermittent lower abdominal or back pain. Under medical guidance, medications such as dydrogesterone tablets, progesterone capsules, or Baotai Ling capsules may be prescribed to support pregnancy and promote recovery.
It is important to get adequate rest and avoid fatigue and strenuous physical activity. Regular prenatal check-ups at the hospital are also essential to monitor fetal development.
