Blood in stool (bright red)

Overview

Bright red blood in stool, also known as hematochezia, is the presence of fresh, vivid red blood mixed with or coating bowel movements. This symptom typically indicates bleeding from the lower digestive tract, including the rectum, anus, or lower colon.

Common Causes

Bright red blood in stool is commonly caused by hemorrhoids, which are swollen blood vessels around the anus that can bleed during bowel movements. Anal fissures, small tears in the anal tissue often from hard stools or straining, are another frequent cause. Dietary factors like consuming large amounts of red foods (beets, tomatoes) or certain medications can sometimes create a similar appearance, though this isn't actual blood.

Severity Levels

Mild: Small amounts of bright red blood occasionally noticed on toilet paper or stool surface, with no other concerning symptoms. May resolve on its own with dietary changes and proper hygiene.

Moderate: Regular episodes of visible blood in stool accompanied by changes in bowel habits, mild abdominal discomfort, or fatigue. Medical evaluation is recommended to identify the underlying cause.

Severe: Large amounts of blood, blood clots in stool, or bleeding accompanied by severe pain, dizziness, weakness, or rapid heart rate. Seek immediate medical attention as this may indicate significant blood loss or a serious condition.

Medical Attention

Seek immediate medical attention if you experience large amounts of bright red blood, blood clots in your stool, or if bleeding is accompanied by severe abdominal pain, dizziness, or weakness. Contact your doctor promptly for any persistent bleeding, even small amounts, or if you notice blood regularly over several days. Don't delay seeking care if you have other concerning symptoms like changes in bowel habits, unexplained weight loss, or if you're taking blood-thinning medications.
