The causes of dry, hard stools and bleeding in defecation include improper diet, internal hemorrhoids, anal fissure, and colon cancer. It can be treated by adjusting diet, medication and surgery. 1. Adjusting diet: if the patient’s stool is dry and hard, when the patient defecates, the dry and knotted fecal matter may scratch the perianal skin and mucous membrane, which will make the patient suffer from the symptom of bleeding in defecation. Therefore, patients can drink more water and dietary fiber-rich fruits and vegetables, so as to alleviate the symptoms of dry and hard stool and bleeding. 2. Medication: If the patient’s stool is dry and hard, and bleeding symptoms occur during defecation, then lactulose, polyethylene glycol, methylcellulose and so on can be taken orally. These drugs can form a certain osmotic pressure in the intestinal tract, absorb the water in the intestinal lumen, thus making the feces become loose and easy to discharge. It is helpful to relieve the symptoms of dry and hard stools and bleeding in defecation. 3. Surgical treatment: if the patient’s colon is cancerous, the cancer cells proliferate a lot and erode the intestinal mucosa and submucosal blood vessels, the patient may have the symptom of bleeding in defecation. If the mass makes the intestinal lumen narrow and the discharge of intestinal contents is obstructed, the patient may have the symptom of constipation. Colon resection can be performed to remove the cancerous bowel to relieve the symptoms of hard, dry stool and bleeding bowel movements. There are many other reasons for the dry, hard and bleeding bowel movements, if the patient has the above symptoms, he should go to the hospital in time, complete the colonoscopy, clarify the cause of the disease, and follow the doctor’s instructions for treatment.
