Hemorrhoid Images and Medical Diagrams

This page provides educational hemorrhoid images, real clinical pictures, and medical illustrations related to hemorrhoids. Visual guides can help patients better understand the anatomy of hemorrhoids, the difference between internal and external hemorrhoids, what thrombosed hemorrhoids may look like, and how various treatments work.

These images and diagrams are intended for educational purposes and may help explain symptoms, diagnosis, and treatment options. Some clinical images may be graphic. Pictures can be helpful, but they cannot confirm a diagnosis or replace an examination by a colorectal specialist.


What Do Hemorrhoids Look Like?

Internal hemorrhoids develop inside the rectum, while external hemorrhoids form under the skin around the anus.

Hemorrhoids can look different depending on whether they are internal, external, thrombosed, or prolapsed. External hemorrhoids may look like swollen tissue or one or more lumps around the anus. Internal hemorrhoids are usually not visible from the outside unless they prolapse through the anus.

A visual guide can help patients understand common appearances, but pictures alone cannot confirm the diagnosis. Anal fissures, skin tags, abscesses, warts, rectal prolapse, inflammatory bowel disease, and tumors may sometimes be confused with hemorrhoids.


Real Pictures of Hemorrhoids vs Medical Diagrams

Real pictures of hemorrhoids can help patients understand the appearance of external hemorrhoids, thrombosed hemorrhoids, and prolapsed hemorrhoids. However, real clinical photos can vary widely based on skin tone, swelling, lighting, thrombosis, ulceration, prolapse, and image quality.

Medical diagrams are often more useful for understanding where hemorrhoids occur, why symptoms develop, and how treatment options work. Real hemorrhoid pictures may show more detail, but they should not be used to self-diagnose rectal bleeding, anal pain, or a new lump.

This real picture shows a thrombosed external hemorrhoid with ulceration. A thrombosed external hemorrhoid occurs when a blood clot forms inside an external hemorrhoid. This can cause sudden pain, swelling, firmness, and a bluish, purple, or dark area near the anus.


External Hemorrhoids Pictures

External hemorrhoids occur under the skin around the anus. They may appear as small swollen areas, soft bumps, or tender lumps near the anal opening. External hemorrhoids are more likely to cause pain, swelling, itching, irritation, or discomfort with sitting and bowel movements.

A thrombosed external hemorrhoid occurs when a blood clot forms inside an external hemorrhoid. This may appear as a painful, swollen, firm lump that can look bluish, purple, red, or dark.


Small External Hemorrhoids Pictures

Small external hemorrhoids may appear as mild swelling or a small lump near the anus. They may cause itching, burning, irritation, or discomfort, especially with constipation, prolonged sitting, wiping, or straining.

Mild symptoms may improve with conservative care such as increasing dietary fiber, drinking adequate fluids, avoiding prolonged straining, and using warm sitz baths. Persistent symptoms should be evaluated to confirm the diagnosis and rule out other anorectal conditions.


Prolapsed Hemorrhoids Pictures

Prolapsed hemorrhoids occur when enlarged internal hemorrhoidal tissue bulges outside the anus. Prolapse may happen during bowel movements and may go back in on its own, require manual reduction, or remain outside the anus.

A fourth-degree hemorrhoid is a severe prolapsed hemorrhoid that remains outside the anus and cannot be manually reduced. Prolapsed hemorrhoids can cause bleeding, mucus drainage, irritation, pressure, hygiene difficulty, or the sensation of tissue coming out during bowel movements.

Hemorrhoids in women generally look similar to hemorrhoids in men. They may appear as external swelling, a tender lump near the anus, prolapsed internal tissue, or a thrombosed external hemorrhoid.

Pregnancy, childbirth, constipation, prolonged straining, and pelvic pressure may contribute to hemorrhoid symptoms in some women. However, rectal bleeding, persistent pain, or a new anal lump should not be self-diagnosed from pictures alone.


Internal vs External Hemorrhoids

Internal hemorrhoids develop inside the rectum, while external hemorrhoids occur under the skin around the anus. Internal hemorrhoids often cause painless bleeding, while external hemorrhoids may cause pain, swelling, or itching.


Thrombosed Hemorrhoid

A thrombosed hemorrhoid occurs when a blood clot forms inside an external hemorrhoid. This can cause sudden pain and swelling near the anus.


Hemorrhoid Prolapse Grades

Grades of internal hemorrhoid prolapse
Internal hemorrhoids are classified into four grades based on prolapse.

Internal hemorrhoids are classified into four grades depending on how much they prolapse outside the anus.

  • Grade I – no prolapse
  • Grade II – prolapse during bowel movements but retract spontaneously
  • Grade III – require manual reduction
  • Grade IV – permanently prolapsed

Rubber Band Ligation Procedure

Rubber band ligation procedure for internal hemorrhoids
Rubber band ligation is a common office procedure for internal hemorrhoids.

Rubber band ligation is a common office procedure used to treat internal hemorrhoids. A small band is placed around the hemorrhoid to cut off blood supply, causing the hemorrhoid to shrink and fall off.


Stapled Hemorrhoidopexy Procedure

Stapled hemorrhoidopexy procedure for prolapsing internal hemorrhoids
Stapled hemorrhoidopexy is a surgical procedure used to reposition prolapsing internal hemorrhoids and reduce blood flow to the hemorrhoidal tissue.

Stapled hemorrhoidopexy is a surgical procedure used to treat prolapsing internal hemorrhoids. During this procedure, a specialized circular stapling device is used to reposition the hemorrhoidal tissue back into its normal position and reduce blood flow to the hemorrhoids. This helps shrink the hemorrhoids and relieve symptoms such as bleeding and prolapse.

This procedure is typically recommended for Grade III or Grade IV internal hemorrhoids, particularly when significant prolapse is present.


Hemorrhoidectomy Surgery

Hemorrhoidectomy surgical removal of hemorrhoids
Hemorrhoidectomy is a surgical procedure used to remove large or severe hemorrhoids when other treatments are not effective.

Hemorrhoidectomy is a surgical procedure used to remove large or severe hemorrhoids. It is usually recommended when hemorrhoids cause persistent symptoms such as bleeding, pain, or prolapse that do not respond to conservative treatments or office-based procedures.

During a hemorrhoidectomy, the surgeon removes the enlarged hemorrhoidal tissue, providing a long-term solution for severe hemorrhoids. Although recovery may take longer than with office procedures, hemorrhoidectomy is considered one of the most effective treatments for advanced hemorrhoids.


When to See a Colorectal Surgeon

You should seek medical evaluation if you have rectal bleeding, severe anal pain, sudden painful swelling, a new or enlarging lump near the anus, drainage, fever, prolapsed tissue that does not go back in, or symptoms that do not improve with conservative treatment.

Hemorrhoid pictures can help with education, but they should not replace a medical examination. A colorectal surgeon can confirm the diagnosis and recommend treatment based on symptoms, examination findings, hemorrhoid type, and severity.

If you are concerned about hemorrhoids, rectal bleeding, anal pain, or a new lump near the anus, you can schedule an appointment with Dr. Aisha Akhtar, MD, a board-certified colorectal surgeon in Phoenix, Arizona.
