The anus is the external opening of the digestive system where the rectum ends.

This is an extremely sensitive area and any damage to this area can result in severe complications. Anyone who noticed a swollen anus should pay attention to this problem. Some of the most common conditions that can lead to a swollen anus include:

1. Hemorrhoids

Swelling of a single vein or a group of veins in the anus is called hemorrhoid. There are 2 types of hemorrhoids:

  • Internal hemorrhoids: The veins inside the anus that are not visible and can't be felt with your hands swell up. The patient may remain asymptomatic until the veins swell to the extent that they block the rectum and anus. Blood with stools is a tell-tale sign of internal hemorrhoids. Besides that, patients usually complain of difficulty passing stools or constipation. Internal hemorrhoids may progress to external hemorrhoids if not treated for a long time.

  • External hemorrhoids: A swelling in the veins of the anus that can be felt with your fingers is called external hemorrhoids. External hemorrhoids are usually detected before the disease progresses. This is because patients suffering from external hemorrhoids notice symptoms and go to the doctor complaining that something is coming out of their anus and pain while passing stools. They may also complain of delayed gastric emptying, heartburn, anorexia (loss of appetite), and bleeding with feces.

Both internal and external hemorrhoids are serious conditions that should not be ignored.

2. Anal Fissure

A tear or break in the inner lining of the anus or lower rectum is called an anal fissure. This can be extremely painful, especially while passing stools. However, there are no fatal complications associated with anal fissures. Anal fissures are common in young males and females. There is no known cause of anal fissure but patients who develop this disease are advised to go on strict diets. Spicy and fried foods are known to worsen the disease and increase the pain. The patient usually presents to his doctor with complaints of stinging sharp pain, typically while passing stools. Most patients suffering from anal fissures try to delay bowel movements because of the fear of pain. A typical feature of a bleeding anal fissure is "blood streaked stools".

3. Anal abscess

The accumulation of pus around the anus is called an anal abscess. This condition occurs when an infection leads to the inflammation and pus formation in a specific area around the anus. This is also an extremely painful condition. Most patients suffering from anal abscesses develop fevers because of the infection. A perianal abscess is the most common type of anal abscess and it looks like a boil-like painful swelling near the anus. The regional temperature is usually raised.

Incision and drainage is the best treatment for this condition.

Diagnosis is Important

It is extremely necessary, in this case, to visit your physician for a checkup. You cannot receive treatment unless you have an accurate diagnosis. The diagnosis is confirmed on the basis of a physical examination and lab tests. Any delay in diagnosis or treatment can result in severe complications.
