Hemorrhoids Q & A

What are hemorrhoids?

Hemorrhoids (piles) are enlarged veins in your anal region. The swollen veins can be very uncomfortable, and often cause symptoms such as:

  • Itching
  • Bleeding
  • Burning sensation 
  • Pain

You can develop internal hemorrhoids that stay within your anal canal or external hemorrhoids that protrude out of your anus.

External hemorrhoids may occasionally form blood clots. The clots can become painful, hard lumps called thrombosed hemorrhoids. 

Internal hemorrhoids can sometimes become large enough to come out of the anus, which can cut off circulation in the affected vein. If this happens, you need urgent medical treatment.

Both types of hemorrhoids can cause blood to appear in your stool, in the toilet bowl, and on the paper after wiping.

What causes hemorrhoids?

The primary cause of hemorrhoids is straining to pass stools. If you have hard stools or often suffer from constipation, the likeliest cause is a diet lacking in fiber and healthy fruits and vegetables, insufficient physical activity, and not drinking enough water.

You’re also more likely to get hemorrhoids as you grow older, especially if there’s a history of having hemorrhoids in your family. If you often have diarrhea or use laxatives regularly, that can also lead to the development of hemorrhoids.

The pressure of having a baby pressing down on your organs and tissues when you’re pregnant is a common cause of hemorrhoids as well.

How are hemorrhoids treated?

Mild hemorrhoids can be managed conservatively. If you think you have hemorrhoids, changing your lifestyle so you steer clear of the avoidable causes can help heal the current problem and prevent future attacks. You can also get creams and suppositories to help the hemorrhoids to heal.

Having hemorrhoids can weaken the veins, so if you go back to your old habits or start straining on the toilet again, your hemorrhoids could well flare up again. If this happens, or your hemorrhoids are particularly troublesome, Dr. Kalan at the Washington Institute of Surgery can help.

There are several options for treating persistent or painful hemorrhoids, including:


An injection of chemicals into the veins closes them off, so blood travels along a different vein.

Infrared, laser, or bipolar coagulation 

These alternative methods close off the veins using energy rather than chemicals.

Rubber band ligation 

A rubber band wrapped around a hemorrhoid causes shrinking, so both hemorrhoid and band fall off after a few days.


Surgical removal of hemorrhoids.

External hemorrhoid thrombectomy 

Thrombectomy is the removal of blood clots from thrombosed hemorrhoids.
