What are Hemorrhoids?

Hemorrhoids are swollen veins located around the anus or in the lower rectum. According to the American Society of Colon and Rectal Surgeons, millions of Americans suffer with hemorrhoids (ASCRS).

There are two types of hemorrhoids, internal and external. Internal hemorrhoids develop within the anus; external hemorrhoids develop outside of the anus. Hemorrhoids are also called piles.

Symptoms of hemorrhoids include:

- Extreme itching around the anus
- Irritation and pain around the anus
- Itchy lump located near your anus
- Fecal leakage
- Painful bowel movement
- Blood on your tissue after having a bowel movement

What causes hemorrhoids?

Hemorrhoid swelling occurs when there is an increase in the pressure in the small vessels that make up the hemorrhoid causing them to swell and engorge with blood. This causes them to increase in size leading to symptoms. Increased pressure may be caused by a variety of factors:

- Low fiber diet
- Prolonged sitting
- Obesity
- Diarrhea, both acute and chronic
- Colon cancer
- Previous rectal surgery
- Spinal cord injury and lack of erect posture
