Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have symptoms of blood in stool and painful bowel movement which could be due to many reasons such as eating a lot of dairy products, irritable bowel syndrome, some medications like antidepressants, acidity and certain conditions like hypothyroidism. Blood in stool can also occur due to constipation , piles and anal fissure. You should start with drinking a lot of water , do light exercises and avoid fatty, poor absorption and inadequate digestion of food , hypothyroidism and heavy meals. I would suggest you to consult gastroenterologist for proper examination. Doctor may order colonoscopy or other tests to look for blockages in your colon , barium studies and blood test for hormonal changes. Doctor may prescribe fiber supplement psyllium, stool softeners and medicine to reduce acidity. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
