Anus Diseases with Symptoms and Pictures - The List with Details

What Are Anus Diseases?

Do you know anus diseases can cause a great trouble in your social life? Anus, the posterior most part of the alimentary canal system, serves as an outlet for the elimination of undigested waste products from the body. Attack of anus diseases causes serious trouble for the victim, especially, in their social life.


Some anus diseases symptoms are mild, while others are of serious nature. Nevertheless, maintaining hygiene and eating healthy diet is the key to avoid any kinds of malfunctioning in the body. However, basic knowledge about the symptoms and treatment measures of different health conditions is also necessary. So, just go through the brief description along with symptoms of some common anus diseases:

Hemorrhoids/Piles - One Of The Painful Anus Diseases

It is one of the very painful anus diseases. The presence of distended varicose veins in the anal region characterizes the condition of hemorrhoids or piles. The valves in the veins permit only unidirectional flow of blood, i.e. back to the heart. However, the weakening of these valves may result in the flow of blood towards wrong direction or its stagnation in veins.

In case of hemorrhoids, there occurs engorging of veins with blood in the anus. Though initially painless, the fragile walls of swollen vein may rupture and result in bleeding with stool. Clot formation in the vessels is very painful and may require surgical removal.

Piles Symptoms:

  • Bowel movements cause bleeding.
  • Appearance of bright red blood on stool, toilet paper or toilet bowl.
  • Itching in the anus.
  • Painful bowel movements.
  • Mucus coming from the anus.

Anal Fissures

Characterized by shallow ulceration or tearing in the tissue along the anal canal, this anal disease is more common among women. The irritation in the fissure, caused by bowel movement, may also trigger a spasm in the surrounding muscle of anus, called anal sphincter.

The spasms are not only painful but may also cause bleeding. One of the major causes of the condition is the movement of large, hard stools that tear the lining of anal canal. Proctitis and other anus diseases may also result from fissures as a secondary complication.


Anal Fissures Symptoms:

  • Bowel movements causing sharp or burning pain in rectum, particularly when the stool is bulky and hard.
  • Bloody streaks on underwear or toilet paper.
  • Bright red blood in stool.
  • Itching in rectum.

Anal Fistula

The development of a small channel between the skin and the end of the large intestine near the anus is named as anal fistula. Besides being painful, it causes bleeding and discharge of pus with the stool. The condition may arise as a secondary complication to surgical removal of anal abscesses. Meanwhile, the closure of channel opening is likely to lead to anal abscesses. Sometimes, it is associated with persistent drainage. The most common treatment measure is the surgical removal of the affected body part.


Anal Fistula Symptoms:

  • Discharge of blood and pus with stool.
  • Painful defecation.
  • Swelling, redness and itching of the skin around anus.
  • Constant, throbbing pain that increases as you sit down.
  • Fever and constipation.

Anal Abscesses

Initially involving the build-up of pus in the anal and rectal area, anal abscesses may occur in any of the two major forms, namely, perianal abscess and anorectal abscess. The most commonly occurring symptoms include constipation, fever, fatigue, bloody stools, pain and pus.

The tissues around the anus become tender and painful. On the other hand, in case of perianal abscess, the victim develops red-colored, warm and painful boil-like swelling around the anus. Whereas, as the name suggests, anorectal abscesses involve the build-up of pus in both the anus and rectum. The treatment involves the use of antibiotics and drainage of the fluid from abscesses through surgery.

Anal Abscesses Symptoms:

  • Development of lump or nodule around the anus.
  • Reddish, warm, boil-like swelling near the anus.
  • Discharge of pus or blood from the anorectal region.
  • Pain during bowel movement.
  • Constipation, fever and fatigue.

Anal Warts

In the beginning, it affects the area inside or around anus and then spreads to genital parts. It is a viral disorder and also has another name, i.e. ‘condyloma acuminata’. Initially appearing as small as the head of a pin, they may grow much larger to cover the entire anal area.

Early stages cause no symptoms, but the advanced stages can give rise to bleeding, itching and discharge of mucus with stools. The causative agent is Human Papilloma Virus (HPV) that an affected individual may communicate to others through sexual contact. However, it may be transmitted without having anal intercourse.


If there is delay in the diagnosis and start of treatment, it is likely to worsen to become anal cancer. The available curative measures include the application of topical medication. However, depending upon the severity of the condition, your health care provider may also recommend the use of liquid nitrogen to freeze the warts or remove them through surgical therapy.

Anal Warts Symptoms:

  • Appearance of tiny spots or growths inside and anal opening.
  • Itching in the affected area.
  • Bleeding with stools.
  • Discharge of mucus.
  • Feeling of a mass in anus.
  • Tiny growths may become much larger with the passage of time.

Pruritus Ani

Affecting men more commonly than women with a 4:1 ratio, pruritus ani is a common medical problem. From 1% to 5% of individuals in the general population may be suffering from this condition. Literally meaning “itchy anus”, it gives rise to a discomforting sensation in the rectal opening, thus triggering a desire in the victim to scratch the affected region.

The injury of skin due to scratching makes irritation more intense and widespread. Scratching also induces the desire to scratch even more.

Depending on severity of the condition, pruritus ani can be classified into primary and secondary forms. Referred to as idiopathic, the primary form may appear without an identifiable cause, while in the secondary case, the cause is identifiable and treatable. Because of the unknown causative agent in the majority of the cases, the treatment is not easy.


Taking fibrous foods and use of bowel medications is useful for the thickening and complete evacuation of stool. Maintaining hygiene is very necessary. The administration of antibiotics can cure infections. Meanwhile, hair dryer can be helpful to keep the skin dry.

Pruritus Ani Symptoms:

  • Unpleasant sensation around rectal opening, arousing desire in the victim to scratch.
  • Development of red spots.
  • Leakage of mucus with stools.
  • Loose stools.
  • Injury resulting from scratching.
  • Cracks, wounds and thickening of skin.
