What causes bleeding during bowel movements in pregnant women?

Bleeding during bowel movements in pregnant women is usually caused by constipation, hemorrhoids, or colorectal lesions. A detailed analysis is as follows:

1. Constipation

Irregular eating habits and frequent consumption of hard-to-digest foods can easily lead to constipation. Dry and hardened stools may injure the intestinal mucosa during defecation, resulting in bleeding. Therefore, it is recommended to maintain healthy dietary habits, consuming more easily digestible foods such as 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 causing hemorrhoidal swellings. This may lead to rupture of rectal blood vessels and result in rectal venous bleeding. Taking warm water baths may help improve blood circulation, reduce hemorrhoidal swelling, and decrease the frequency of hemorrhoid flare-ups.

3. Colorectal Lesions

If significant bleeding occurs during bowel movements, it may indicate a pathological condition in the rectum or colon, such as inflammation, polyps, or tumors. It is advisable to seek medical attention promptly and receive targeted treatment under a physician's guidance.

In addition to the above causes, bleeding may also be due to threatened miscarriage. It is recommended to visit a professional medical facility for proper evaluation and diagnosis.
