** Thanks for contacting with your health concern 1. At his age [schoool going], the most common conditions of rectal bleeding to exclude are constipation, polyps, infections and inflammatory bowel disease and as such referral to a pediatric gastroenterologist is necessary. 2. since physical examination of the patient is of utmost importance thus I at most can tell you the symptomwise approach that has to be followed i. examination of stool ii. Vitals [pulse, heart rate, orthostatic blood pressure] iii. Inspection of the skin [for pallor] and palpation of the abdomen [for any mass] iv. rectal examination for fissures, polyps, hemorrhoids. v. Others: CBC, C Reactive protein, ESR vi. colonoscopy with biopsy [if needed] PS. Treatment will depend on the exact cause of rectal bleeding.
