Pregnancy generally aggravates hemorrhoids. Hemorrhoids are a type of varicose vein mass that is mostly caused by increased abdominal pressure, constipation, and difficulty in defecating, which causes the nucleus to prolapse out of the anus. The hemorrhoids can easily come out of the anus after prolonged standing, sitting, and eating spicy foods and drinking a lot of alcohol. 1. The stomach of a pregnant woman is relatively large during pregnancy, which leads to increased abdominal pressure that can press back on the rectum and lead to poor bowel movements. 2. Pregnancy can lead to poor reflux in the perianal hemorrhoidal veins, which can lead to venous stasis and promote the formation of hemorrhoids. Therefore, pregnant women can aggravate hemorrhoids.
