Anal bleeding, also known as rectal bleeding, refers to the passage of blood from the anus or rectum. This condition can manifest in various ways, including bright red blood on toilet paper, red streaks on stool, or pink-tinged water in the toilet bowl.

• Colorectal polyps or cancer
• Inflammatory bowel diseases: Such as ulcerative colitis or Crohn’s disease
• Diverticulosis: Abnormal pouches in the colon

Less common causes may include anal fistulas, infections, or trauma.

Diagnosis

Diagnosis typically involves:

• Medical history review
