Hello, this sounds like bleeding from hemorrhoids. You haven t mentioned any discomfort during defecation, so an anal fissure or external hemorrhoids are less possible. Internal hemorrhoids though, may cause bleeding without any discomfort at all and they do cause streaks of blood on the stool and also blood on the toilet paper. Other - more serious - diagnoses cannot be excluded though and clinical examination (and perhaps also endoscopic evaluation) is important. If hemorrhoids is indeed the diagnosis then managing constipation is the solution. Drinking enough water, walking or exercising and eating a lot of fiber really help. If the bleeding or the symptoms get out of control, surgical approaches also exist. I hope I ve helped! You can contact me, if you d like more information. Kind Regards!
