The common reasons for bleeding in the stool in early pregnancy are the following: First, in early pregnancy the distended uterus tends to compress the rectal veins, thus making the venous blood return poor and easy to bruise. Early pregnancy is prone to abdominal distension, gastrointestinal function is reduced, the intestines are easily compressed by fecal masses, blood return is obstructed, which can lead to swelling of the hemorrhoid nucleus stasis and rupture of the hemorrhoid vein thus causing bleeding. The bleeding in the stool in early pregnancy is bright red, relatively red in color, and the blood does not mix with the stool, but bleeds in the form of dots or drops. The pregnant woman is weaker in early pregnancy, the blood vessels of the hemorrhoid plexus tend to be fibrotic, brittle and thin, and the local varicose veins easily occur resulting in bleeding. Second, early pregnancy stool bleeding may be long-term constipation, dry stool is easy to damage the skin of the anal canal, resulting in fissures, and the surface of the stool will be bloody when wiping the stool.
