Difference between Fistula and Hemorrhoids

In order to understand the difference between fistulas and hemorrhoids, it is important to first understand the anatomy of the rectum and anus. The rectum is the section of the large intestine that connects to the anus. The anus is the opening at the end of the rectum where stool passes out of the body. Fistulas are abnormal passageways that form between two different organs or vessels. Hemorrhoids are swollen veins in and around the anus.

What is Fistula?

A fistula is an abnormal connection between two body cavities or between an internal organ and the surface of the body. Fistulas can occur in the digestive system, reproductive system, urinary tract, or in other parts of the body. They are usually caused by trauma, surgery, or infection.

In some cases, fistulas can close on their own. However, many fistulas require medical treatment to heal properly. Treatment options include medication, surgery, and lifestyle changes. Fistulas can be a nuisance and cause discomfort, but with proper treatment, they can usually be healed without any lasting effects.

What are Hemorrhoids?

Hemorrhoids are swollen and inflamed veins in the rectum and anus. They can be internal, which means they’re inside the rectum. Or they can be external, which means they’re under the skin around the anus. Hemorrhoids often cause bleeding during bowel movements, as well as itching, pain, and irritation.

Internal hemorrhoids may prolapse, or protrude, through the anal opening. They can also thrombose, or form blood clots. External hemorrhoids may thrombose and become very painful. Hemorrhoids are common in adults, especially those who are overweight or obese. Pregnant women are also more likely to get them.

Difference between Fistula and Hemorrhoids

A fistula is an abnormal passageway that forms between two body tissues or organs. Fistulas can develop anywhere in the body, but they most commonly occur in the gastrointestinal tract.

  • Fistulas can be either internal or external. External fistulas form when there is an opening between the skin and another organ, such as the intestine. Internal fistulas form when there is an opening between two organs inside the body, such as the bladder and rectum.
  • Hemorrhoids are swellings that occur when veins in the anus and rectum become enlarged. Hemorrhoids can be either internal or external. External hemorrhoids are located under the skin around the anus. Internal hemorrhoids are located inside the rectum.
  • Hemorrhoids are not dangerous, but they can cause discomfort and bleeding. Treatment for hemorrhoids often includes over-the-counter creams or suppositories. In some cases, surgery may be necessary to remove hemorrhoids.


Hemorrhoids are a type of vascular structure in the anal canal. There are two types of hemorrhoids-internal and external. Internal hemorrhoids are usually not painful but may bleed during bowel movements. External hemorrhoids are more likely to cause pain and swelling because they are located closer to the surface of the skin. Hemorrhoids can develop either due to increased pressure on the veins in the anal area or as a result of straining during bowel movements. Fistulas, on the other hand, occur when an abnormal connection forms between two different parts of the body. A fistula most commonly develops between an abscess and the skin, but it can also form between organs such as the rectum and vagina.
