In late pregnancy, the uterus swells and tends to compress the rectal veins, thus blocking the venous return, because the rectal veins and their branches lack venous valves, blood does not flow back easily and tends to pool, and in late pregnancy the hemorrhoid nucleus pools and swells, and the hemorrhoid veins rupture, thus causing bleeding. Bleeding from hemorrhoids in late pregnancy is bright red, sometimes spot or drip bleeding, and blood in the stool does not mix with feces. In late pregnancy, due to reduced gastrointestinal motility, it is easy to cause abdominal distension, indigestion and constipation, which leads to obstruction of fecal discharge, and fecal pressure on the rectum leads to swelling of the hemorrhoid nucleus, which leads to bleeding hemorrhoids. So there are many reasons for bleeding hemorrhoids in late pregnancy, you should pay attention to your diet, avoid spicy and stimulating foods, drink more water, eat less and more meals, move properly to promote gastrointestinal motility, and keep the perianal area clean to reduce bleeding hemorrhoids.
