Dr. Cheng Yicheng
Bleeding during bowel movements may result from improper diet, anal fissures, or other causes. During pregnancy, consuming excessive spicy or “heat-inducing” foods can impair gastrointestinal motility, leading to constipation and subsequently hemorrhoids, which may cause rectal bleeding. Additionally, reduced physical activity during pregnancy, coupled with uterine compression of the intestines, often results in constipation and hard stools. These conditions can cause tears in the anal canal skin—known as anal fissures—leading to rectal bleeding and painful defecation.
