Dry stools are usually caused by constipation due to less drinking water or less fiber in the diet. Bleeding may be caused by anal fissure, hemorrhoids or intestinal cancer, etc., which need to be analyzed specifically. 1. Anal fissure: due to drinking less water and food containing more fiber, when defecating due to the body too hard and other reasons, resulting in intestinal tract tearing, causing bleeding. 2. Hemorrhoids: patients may have hemorrhoids due to constipation or prolonged sedentary life, which will cut the surface of hemorrhoids when the stool is dry, resulting in bleeding, mainly fresh blood stool. 3. Bowel cancer: Bowel cancer patients may suffer from bleeding due to the rupture of bowel cancer, coupled with the recent consumption of food containing more fiber, which will cause dry stool with bleeding. Dry stool with bleeding may also be caused by other reasons, such as rectal polyps, coagulation disorders, rectal prolapse and other diseases. It is recommended that once patients find themselves with similar symptoms, they should consult a doctor to complete the relevant examinations, make a clear diagnosis and follow the doctor’s instructions to standardize the treatment.
