Reasons for farting blood?

Red or black/tarry? The fresher and redder the blood is, the closer the problem is to the "exterior" or "". The darker, tarrier the blood is means the problem is farther in. If it is fresh and red, it may be because the farting aggravated abnormalities, like hemorrhoids or fissures. If it is farther in, it's time to freak out and get a colonoscopy. Good luck.
