Blood in stool without pain may be caused by anal fissure, rectal polyps, ulcerative colitis, intestinal tumors, and other diseases. It is recommended that patients seek medical attention promptly, identify the cause under the doctor's diagnosis, and receive targeted treatment. Here are some possible causes and treatments:
1. Anal Fissure: It is usually caused by long-term constipation or diarrhea, leading to the rupture of the anal canal skin, resulting in blood in stool, but generally without pain symptoms. Patients can be treated with nitroglycerin ointment, erythromycin ointment, and other medications under the guidance of a doctor.
2. Rectal Polyps: It is often caused by genetic factors or improper diet. When the polyps are large, they may irritate the local mucosa, causing blood in stool, but generally without pain symptoms. Patients can be treated with endoscopic mucosal resection or other methods under the guidance of a doctor.
3. Ulcerative Colitis: It is usually caused by immune dysfunction or genetic factors. Due to the inflammatory stimulation of the intestinal mucosa, it can lead to mucosal erosion and bleeding, resulting in the above situation. Patients can be treated with mesalazine enteric-coated tablets, sulfasalazine enteric-coated tablets, and other medications under the guidance of a doctor.
4. Intestinal Tumors: It is often caused by unhealthy lifestyle habits or genetic factors. When intestinal tumors grow to a certain extent, they may invade surrounding tissues and blood vessels, resulting in the above situation. If it is a benign tumor, it can be treated by surgical removal. If it is a malignant tumor, radiotherapy, chemotherapy, and other adjuvant treatments may be required under the doctor's guidance.
In addition, it may also be related to leukemia. In daily life, pay attention to rest, maintain sufficient sleep time, and avoid staying up late. At the same time, pay attention to a light diet and eat more fruits and vegetables rich in dietary fiber, such as grapefruit, loofah, eggplant, etc.
