Rectal Bleeding

The most common cause of bleeding from the rectum in middle-aged and older adults is hemorrhoids.¹ Bleeding hemorrhoids are caused by hard stool that damages the hemorrhoid tissue. Despite hemorrhoid bleeding being one of the most common symptoms, it’s also the most misunderstood. 

There are two types of hemorrhoids, internal and external, and both can cause bleeding. External hemorrhoids develop under the skin around the anus, while internal hemorrhoids are enlarged veins in the rectum, so they aren’t visible outside the body. Although both types can cause bleeding, internal hemorrhoids are more likely to experience bleeding as a symptom.²

Persistent or heavy rectal bleeding should never be ignored. Understanding why hemorrhoids are bleeding and how long bleeding may last can help you know when to seek medical evaluation to find relief sooner.

What Does Rectal Bleeding Mean?

Rectal bleeding refers to any blood that passes from the anus, often noticed on toilet paper, in the toilet bowl, or mixed with stool.

In many cases, rectal bleeding is caused by internal hemorrhoids, especially when the blood appears bright red and painless. However, not all bleeding comes from hemorrhoids, and understanding the difference is important.

At USA Hemorrhoid Centers, rectal bleeding is one of the most common symptoms that brings patients in for evaluation—especially when it becomes recurrent, persistent, or concerning.

Common Causes of Rectal Bleeding

While hemorrhoids are a leading cause, rectal bleeding can result from several conditions. It’s important not to assume the cause without evaluation.

1. Internal Hemorrhoids (Most Common Cause)

• Typically painless bleeding
• Bright red blood
• May be associated with prolapse or pressure

2. Anal Fissures

• Small tears in the anal lining
• Often cause sharp pain during bowel movements
• Bleeding is usually minimal but noticeable

3. Gastrointestinal Conditions

• Inflammatory bowel conditions
• Polyps or growths in the colon
• Diverticular disease

4. Other Causes

• Infections
• Rectal irritation
• Less commonly, more serious colorectal conditions

Important: Even if you suspect hemorrhoids, rectal bleeding should always be properly evaluated to rule out other causes.

Why Hemorrhoids Bleed

Bleeding hemorrhoids typically occur during or after bowel movements due to straining or irritation. Hemorrhoidal tissue consists of cushions of connective tissue and blood vessels that line the anal canal. This tissue typically fills with blood and swells during a bowel movement, then returns to its normal size when the stool has passed. 

However, when a hard stool or excessive pressure during a bowel movement nicks a blood vessel in a hemorrhoid or ruptures the thin wall of a blood vessel, it will bleed. Someone experiencing hemorrhoid bleeding may notice this symptom by seeing bright red blood on toilet paper after bowel movements.  

Why Internal Hemorrhoids Bleed

Internal hemorrhoids are swollen veins inside the rectum. These veins can become irritated or inflamed due to:

• Straining during bowel movements
• Chronic constipation or diarrhea
• Increased abdominal pressure
• Prolonged sitting

Because internal hemorrhoids are located inside the rectum, they often bleed without causing pain, especially in earlier stages.

How Much Hemorrhoid Bleeding is Considered Normal?​

What is considered normal hemorrhoid bleeding is a few drops of bright red blood after a bowel movement. The blood may be accompanied by other hemorrhoid symptoms, such as:

• Irritation and itching around the anus
• Pressure around the anus
• A slight bulge or lump on or near the anus
• Feeling as though your bowels are not emptied

Internal hemorrhoids are the most frequent source of painless, bright-red rectal bleeding. External hemorrhoids bleed far less often but may do so if they rupture or are irritated. Persistent, heavy, and dark red blood may indicate a more serious issue requiring medical attention.

How Long Do Hemorrhoids Bleed​?

Hemorrhoids may stop bleeding within a few days, especially when related to temporary irritation or a single episode of hard stool. However, bleeding may continue or recur with internal hemorrhoids if there is ongoing constipation or straining. Prolapsed hemorrhoids can also lead to more frequent bleeding, along with untreated hemorrhoids that require medical attention.  

If bleeding persists for more than a few days, consult a hemorrhoid specialist for a diagnosis and to discuss potential treatment options.

What Does Hemorrhoid Bleeding Look Like?

Bleeding from hemorrhoids has some recognizable patterns:

• Bright red blood on toilet paper
• Blood dripping into the toilet after a bowel movement
• Streaks of blood on the stool surface
• Bleeding without significant pain (common with internal hemorrhoids)

When to See a Hemorrhoid Doctor About Rectal Bleeding

Although hemorrhoid bleeding itself is usually not dangerous, it can lead to other concerning conditions. 

One of the dangers of bleeding hemorrhoids is that it can cause chronic or heavy bleeding, leading to fatigue, dizziness, iron-deficiency anemia, or may signal a more serious condition. If bleeding lasts more than a few days, it is time to consult a hemorrhoid specialist to rule out other potential causes of rectal bleeding, such as anal fissures, colon polyps, or colorectal cancer.

Along with these symptoms of a bleeding hemorrhoid, seeking medical attention is recommended when: 

• The bleeding persists for a week or longer
• It comes and goes over time
• Is heavy or accompanied by clots
• Is accompanied by changes in bowel habits
• Is dark red or maroon in color

 FAQs About Hemorrhoid Bleeding

Is bright red blood always hemorrhoids?

No. While bright red blood is commonly associated with hemorrhoids, it can also come from other sources. Proper evaluation is important.

Should I be worried if my hemorrhoid is bleeding?

Usually, there is no need to worry about bleeding hemorrhoids, as they can resolve on their own within a few days. However, if bleeding lasts longer than a week or becomes heavy, consult a hemorrhoid specialist.

What happens if you leave bleeding hemorrhoids untreated?

If you leave bleeding hemorrhoids untreated, they are more likely to become thrombosed, which is when a blood clot forms in the hemorrhoid. They can cause severe pain, bleed more, and end up requiring surgery.

Are bleeding hemorrhoids common during pregnancy?

Bleeding hemorrhoids are common during pregnancy, due to the extra pressure caused by a growing uterus, hormonal changes, and constipation. Although bleeding can be common during pregnancy, evaluation is recommended if symptoms don’t improve within a few days.
