What Does "Blood in Stool" Look Like?

Blood in stool can appear in different ways, and the appearance often gives clues about where the bleeding may be coming from:

• Bright red blood on the toilet paper or in the toilet bowl
  Often linked to bleeding near the end of the digestive tract, such as the rectum or anus.
• Dark red or maroon stool
  May suggest bleeding higher in the colon or small intestine.
• Black, tarry stool (sometimes with a strong odor)
  Can indicate bleeding in the upper digestive tract, such as the stomach.
• Blood mixed into the stool
  May point to inflammation or bleeding inside the intestines.

If blood in stool continues for several days, even in small amounts, it deserves attention.

Common Causes of Blood in Stool

Many cases of blood in stool are caused by conditions that are uncomfortable but not life-threatening. Common causes include:

• Hemorrhoids
  Swollen veins in the rectum or anus. Often cause bright red blood, especially after straining or passing hard stools.
• Anal fissures
  Small tears in the skin of the anus, commonly due to constipation. These can cause pain and bleeding.
• Constipation
  Hard stools can irritate or tear tissue, leading to bleeding.
• Diarrhea or frequent bowel movements
  Can inflame the lining of the rectum or anus, causing small amounts of blood.

These causes often improve with diet changes, hydration, and proper treatment—but bleeding should still be monitored.

Digestive Conditions That Can Cause Ongoing Bleeding

If blood in stool lasts for several days or keeps coming back, digestive conditions may be involved, such as:

• Inflammatory bowel disease (IBD)
  Conditions like ulcerative colitis or Crohn's disease can cause ongoing inflammation, diarrhea, abdominal pain, and bloody stools.
• Diverticular disease
  Small pouches in the colon wall can bleed suddenly and sometimes heavily.
• Infections of the gut
  Certain bacterial or parasitic infections can cause bloody diarrhea, often with fever or cramping.
• Colon polyps
  Growths in the colon that may bleed. Some polyps can develop into cancer over time if not treated.

These conditions usually require medical evaluation and specific treatment.

More Serious Causes to Be Aware Of

While less common, some serious conditions can cause blood in stool. It is important to be aware without jumping to conclusions:

• Colorectal cancer
  Blood in stool may be one of the early signs, especially if it is ongoing or combined with changes in bowel habits or unexplained weight loss.
• Stomach or intestinal ulcers
  These can bleed slowly over time, leading to dark or black stools.
• Blood vessel problems in the digestive tract
  Abnormal or fragile blood vessels can bleed intermittently.

Early detection greatly improves outcomes, which is why ongoing bleeding should never be ignored.

When Blood in Stool Needs Urgent Care

You should speak to a doctor promptly or seek urgent care if blood in stool is accompanied by:

• Dizziness, weakness, or fainting
• Shortness of breath or chest discomfort
• Severe or worsening abdominal pain
• Fever and dehydration
• Large amounts of blood or clots
• Black, tarry stools lasting more than a day

These signs may indicate significant blood loss or a serious underlying condition.
