What Is IRC (Infrared Coagulation)?

Infrared Coagulation (IRC) is a minimally invasive, non-surgical treatment for internal hemorrhoids. It uses infrared light to create controlled heat, which causes the hemorrhoidal tissue to shrink and scar. This scar tissue cuts off the blood supply to the hemorrhoid, resulting in its gradual disappearance over time.

IRC is commonly used for Grade I and Grade II internal hemorrhoids and may be considered for some cases of Grade III hemorrhoids. It’s typically done in an outpatient setting with little to no downtime.

How Does the Procedure Work?

During an IRC procedure:

  • You will lie comfortably on your side in a private exam room.
  • A small anoscope is gently inserted into the rectum to view the hemorrhoid.
  • An infrared light probe is applied to the hemorrhoidal tissue for 1–2 seconds at multiple points.
  • The heat creates a small burn that seals the blood vessels and stimulates scarring.

The entire procedure usually takes less than 10 minutes and does not require anesthesia.

Who Is a Candidate for IRC?

IRC is best suited for patients with:

  • Bleeding internal hemorrhoids (Grade I or II)
  • Mild prolapse that returns spontaneously
  • Symptoms such as rectal bleeding, itching, or minor discomfort

It is not recommended for external hemorrhoids or more advanced cases where surgical intervention may be more appropriate.

Benefits of Infrared Coagulation

  • Minimally invasive: No incisions or stitches
  • Fast and convenient: Often performed in under 10 minutes
  • Low risk of complications: Less pain and bleeding compared to surgery
  • No need for anesthesia or hospital stay
  • Quick return to normal activities: Most patients resume work the same day

What to Expect After the Procedure

After IRC, you may experience mild discomfort or a sensation of fullness in the rectum for a day or two. Over-the-counter pain relievers and warm sitz baths can help ease symptoms.

Most patients require 2 to 4 treatments spaced a few weeks apart for full relief. Your doctor will guide you based on your symptoms and the number of hemorrhoids present.

Risks and Side Effects

While complications are rare, possible side effects include:

  • Minor bleeding
  • Rectal discomfort or pressure
  • Temporary urgency to have a bowel movement

Serious complications such as infection or severe bleeding are extremely rare when the procedure is performed by a qualified gastroenterologist.

How to Prepare for IRC

Before the procedure:

  • Inform your doctor about any medications, especially blood thinners.
  • A bowel movement or mild enema may be recommended prior to your appointment.
  • No special dietary restrictions are typically required.

Tips for Recovery and Hemorrhoid Prevention

To prevent hemorrhoids from recurring after treatment:

  • Eat a high-fiber diet (vegetables, fruits, whole grains)
  • Drink plenty of water throughout the day
  • Avoid prolonged sitting or straining during bowel movements
  • Exercise regularly to promote healthy bowel function

FAQs About Infrared Coagulation

Is IRC painful?

The procedure is usually well tolerated. Most patients report only mild pressure or warmth during treatment.

How many treatments will I need?

Most people need 2 to 4 sessions to fully treat their hemorrhoids.

Can IRC be used on external hemorrhoids?

No. IRC is designed for internal hemorrhoids. Other treatments are better suited for external issues.

Will I need time off work?

Most patients return to normal activities the same day or the next day.

Is IRC covered by insurance?

Yes, in most cases. Coverage may depend on your plan and diagnosis. Check with your provider for details.

Final Thoughts from Your Gastroenterologist

IRC is a safe, effective, and minimally invasive option for treating internal hemorrhoids. If you’re experiencing rectal bleeding, itching, or discomfort, don’t ignore your symptoms. Early treatment leads to better outcomes and a faster return to comfort. Contact your gastroenterologist to find out if IRC is right for you.
