There are several potential causes of hematochezia in children, including but not limited to:
Anal fissures: Small tears in the lining of the anus, often caused by constipation and straining during bowel movements. Infectious colitis: Inflammation of the colon due to bacterial, viral, or parasitic infections. Inflammatory bowel disease (IBD): Conditions such as Crohn's disease and ulcerative colitis that cause chronic inflammation of the GI tract. Juvenile polyps: Benign growths that can cause painless rectal bleeding. Meckel's diverticulum: A congenital anomaly that can cause painless bleeding. Allergic colitis: Inflammation due to an allergic reaction, often seen in infants with cow's milk protein intolerance.
