Can Hemorrhoids Burst?

In everyday language, people may describe a bleeding hemorrhoid as having “burst” or “popped.” Medically, two different situations may be involved:

1. A thrombosed external hemorrhoid may become swollen enough that the skin over it breaks down and releases blood or part of the clot.
2. An internal hemorrhoid may bleed when its delicate surface is irritated during a bowel movement.

The first situation can resemble a ruptured lump. The second is hemorrhoidal bleeding rather than a true rupture.

A small amount of bright red blood may stop without treatment. However, rectal bleeding should not automatically be assumed to come from hemorrhoids, particularly when it is heavy, recurrent, mixed into the stool, or associated with other symptoms.

Seek emergency care: Go to an emergency department or call 911 for heavy or continuous bleeding, fainting, marked dizziness, confusion, shortness of breath, a rapid heartbeat, severe abdominal pain, or black, tarry stool.

What Does a “Burst Hemorrhoid” Usually Mean?

A “burst hemorrhoid” most commonly refers to spontaneous drainage from a thrombosed external hemorrhoid.

A thrombosed external hemorrhoid develops when a blood clot forms beneath the skin at the anal opening. It typically causes:

• A sudden, firm lump near the anus
• Blue, purple, or dark discoloration
• Constant tenderness or pain
• Pain while sitting, walking, or having a bowel movement
• Swelling around the anal opening

Pressure within the swollen tissue may occasionally cause the overlying skin to break down. Dark blood, bright red blood, or clotted material may then leak from the area.

Can an Internal Hemorrhoid Burst?

Internal hemorrhoids do not commonly “burst” in the same way as a thrombosed external hemorrhoid.

Internal hemorrhoids are covered by delicate rectal tissue. When that tissue is irritated or traumatized by stool, straining, or prolapse, it may bleed.

Typical internal hemorrhoid bleeding is:

• Bright red
• Painless
• Seen on toilet paper
• Present on the outside of the stool
• Visible as drops in the toilet after a bowel movement

Because other colorectal conditions can produce the same bleeding pattern, the appearance of the blood does not confirm that an internal hemorrhoid is responsible.

What Causes a Thrombosed Hemorrhoid to Drain?

The exact trigger is not always identifiable. Factors associated with increased pressure or irritation around the anus include:

• Straining during bowel movements
• Constipation or hard stool
• Frequent diarrhea
• Prolonged sitting on the toilet
• Pregnancy
• Heavy lifting
• Irregular bowel habits
• Repeated rubbing or cleaning of the anal area

These factors may contribute to hemorrhoidal swelling or external hemorrhoidal thrombosis, but they do not mean that every episode of rectal bleeding is hemorrhoidal.

What Does a Draining Thrombosed Hemorrhoid Look Like?

You may notice:

• Blood from a painful lump near the anus
• Dark red or clotted blood
• A small opening in the skin over the lump
• Blood on underwear, gauze, or toilet paper
• Reduced pressure after drainage
• Continued swelling or tenderness

Pain may improve after some of the clot drains, but relief is not guaranteed. Part of the clot may remain beneath the skin, and the open area may continue to ooze temporarily.

A colorectal examination is appropriate when the diagnosis is uncertain, pain is severe, or bleeding continues.

What Should You Do If a Hemorrhoid Starts Bleeding?

Apply Gentle Pressure

Place clean gauze or a clean absorbent pad over the area and apply firm, continuous pressure for several minutes.

Avoid repeatedly removing the gauze to check the bleeding, because this may disturb early clot formation.

Clean the Area Gently

Rinse with warm water and pat the skin dry.

Avoid:

• Vigorous wiping
• Fragranced wipes
• Harsh soaps
• Alcohol or hydrogen peroxide
• Scrubbing the open area

These products may irritate the tissue and delay healing.

Use a Warm Sitz Bath

Sitting in warm water may reduce pain and anal sphincter tension.

A sitz bath may be used for approximately 10–15 minutes, particularly after bowel movements. Use comfortably warm—not hot—water.

Keep Stool Soft

Reducing constipation and straining can limit additional trauma.

Helpful measures include:

• Gradually increasing dietary fiber
• Using a fiber supplement when appropriate
• Drinking fluids according to your medical needs
• Avoiding prolonged toilet sitting
• Responding promptly to the urge to have a bowel movement

High-fiber foods and appropriate fluid intake can make stool softer and easier to pass.

Protect Clothing

A small gauze pad or absorbent liner may be used temporarily if minor drainage continues. Change it regularly and keep the area clean and dry.

Do Not Pop or Drain a Hemorrhoid Yourself

Do not puncture, squeeze, cut, or attempt to remove a hemorrhoidal clot at home.

Self-drainage can cause:

• Uncontrolled bleeding
• Additional tissue injury
• Severe pain
• Contamination of the wound
• Delayed diagnosis of another condition

When drainage or excision is appropriate, it should be performed by a qualified clinician using sterile equipment and appropriate anesthesia.

When Should You See a Doctor?

Arrange a medical evaluation when:

• Bleeding continues or repeatedly returns
• The amount of blood is increasing
• The diagnosis of hemorrhoids has not been confirmed
• Blood appears mixed throughout the stool
• A painful lump is large or worsening
• Pain interferes with sitting, walking, sleeping, or bowel movements
• You develop fever, pus, increasing redness, or worsening swelling
• You take an anticoagulant or antiplatelet medication
• Bleeding is accompanied by abdominal pain or altered bowel habits
• You have unexplained weight loss, fatigue, or anemia
• You have a personal or family history of colorectal polyps or cancer

Rectal bleeding should not automatically be attributed to hemorrhoids. Other causes include anal fissures, inflammatory bowel disease, diverticular disease, vascular abnormalities, colorectal polyps, and colorectal cancer.

When Is Hemorrhoid Bleeding an Emergency?

Seek immediate medical care for:

• Heavy or continuous bleeding
• A toilet bowl filling with blood
• Passage of large blood clots
• Fainting or near-fainting
• Marked dizziness or weakness
• Confusion
• Shortness of breath
• A rapid heartbeat
• Pale or clammy skin
• Severe abdominal pain
• Black, sticky, tar-like stool

These symptoms may indicate significant gastrointestinal blood loss or bleeding from a source other than hemorrhoids.

How Is a Thrombosed External Hemorrhoid Treated?

Treatment depends on:

• Severity of pain
• Duration of symptoms
• Amount of bleeding
• Size of the thrombosis
• Examination findings
• Patient preference and medical history

Conservative Treatment

Many patients can be managed without a procedure using:

• Fiber and stool-softening measures
• Warm sitz baths
• Appropriate pain medication
• Avoidance of straining
• Observation as the clot is gradually reabsorbed

Most patients managed nonoperatively eventually improve, although the time required varies.

Surgical Excision

Selected patients with severe symptoms may benefit from early removal of the thrombosed external hemorrhoid.

The 2024 ASCRS guideline reports that excision may provide:

• Faster symptom relief
• Reduced recurrence
• Longer intervals without symptoms

The decision should be individualized after an examination. Simply opening the hemorrhoid and expressing the clot is not equivalent to complete excision and may have a higher risk of recurrence.

Can a Bleeding Hemorrhoid Become Infected?

Infection after spontaneous drainage is uncommon, but an opening in the skin should be kept clean.

Seek medical attention for:

• Fever
• Pus or foul-smelling drainage
• Spreading redness
• Increasing warmth or swelling
• Pain that becomes worse rather than better
• Difficulty urinating
• General illness or chills

These findings are not typical of uncomplicated hemorrhoidal bleeding.

How Long Does Bleeding Last?

Minor bleeding may stop after direct pressure or after the bowel movement ends. Drainage from a thrombosed external hemorrhoid may continue intermittently while the skin opening heals.

There is no universal safe duration for rectal bleeding. Evaluation is appropriate when bleeding:

• Does not stop
• Returns repeatedly
• Becomes heavier
• Occurs without a confirmed hemorrhoid
• Continues after hemorrhoid symptoms otherwise improve

Do not continue treating unexplained bleeding at home solely because the blood is bright red.

How Can You Prevent Another Thrombosed Hemorrhoid?

Preventive measures focus on reducing constipation, straining, and prolonged pressure on the anal area:

• Eat an appropriate amount of dietary fiber.
• Drink fluids according to your health needs.
• Avoid straining during bowel movements.
• Limit time spent sitting on the toilet.
• Treat recurring constipation or diarrhea.
• Exercise regularly when medically appropriate.
• Avoid delaying bowel movements.
• Seek treatment for recurrent hemorrhoidal symptoms.

These measures may lower the risk of recurrent symptoms but cannot prevent every thrombosed external hemorrhoid.
