Anal urgency may be caused by acute hemorrhagic necrotizing enterocolitis, rectal polyps, anal fissure and other causes. 1. Acute hemorrhagic necrotizing enterocolitis: acute necrotizing intestinal disease due to a variety of causative factors, high fever, abdominal pain, diarrhea and other symptoms may occur. At the same time, painful stimuli may lead to anal urgency. 2. Rectal polyps: abnormal growths occurring on the rectal mucosa, usually caused by chronic stimulation of digestive products, which may be accompanied by a feeling of anal urgency. 3. Anal fissure: generally refers to a fissure on the anal verge, which may lead to tingling in the anus, thus causing the sphincter muscle to contract continuously, resulting in anal urgency. It may also lead to blood dripping from the anus during bowel movement, accompanied by severe pain after defecation. It is recommended to go to the hospital in time for anal urgency, undergo relevant examinations, make a clear diagnosis, and be treated under the guidance of a professional doctor.
