Infrared Coagulation for Hemorrhoids Explained

Blog

Hemorrhoids are incredibly common, and for many patients, at-home remedies like fiber supplements or topical creams don’t provide long-term relief. That’s where office-based treatments, such as infrared coagulation (IRC), come in. At NYGA, our gastroenterologists offer IRC as a gentle, nonsurgical option to shrink hemorrhoids and help you get back to feeling your best.

What is infrared coagulation treatment for hemorrhoids?

Infrared coagulation is a minimally invasive procedure that uses infrared light to treat internal hemorrhoids. A small probe delivers a quick pulse of infrared energy to the base of the hemorrhoid, creating a controlled burn that cuts off the blood supply. Without blood flow, the hemorrhoid will shrink and scar down.

The procedure is quick, typically lasting 10 minutes, and no anesthesia or sedation is required. With no cutting or stitches involved, IRC is an appealing choice for patients with grade 1 or 2 internal hemorrhoids.

Benefits and Risks of Infrared Coagulation

One of the main advantages of IRC is its simplicity. The procedure is performed in the office, requires no downtime, and is usually well-tolerated with minimal discomfort. Most patients can resume normal activities the same day.

Some additional benefits of IRC include:

Nonsurgical and minimally invasive
Fast procedure with no prep required
Little to no recovery time
Optimal for early-stage hemorrhoids

Like any medical procedure, there are some risks, although they are rare. Mild bleeding or a sensation of fullness in the rectum is common for a day or two after treatment. Serious complications like infection or significant bleeding are highly uncommon, especially when performed by an experienced gastroenterologist.

How does infrared coagulation shrink hemorrhoids?

The heat from the infrared light causes the blood vessels feeding the hemorrhoid to clot and shrink. Over time, the treated tissue scars down, which helps anchor the vein in place and prevents it from prolapsing or bleeding.

You won’t feel the infrared energy itself, but you may notice a warm sensation or slight cramping during the procedure. There's no need for fasting or bowel prep beforehand, and because IRC doesn’t involve cutting or suturing, it’s associated with far less pain than surgical hemorrhoidectomy.

Will my hemorrhoids return after IRC?

IRC can be a highly effective long-term solution for small internal hemorrhoids, especially when combined with diet and lifestyle changes. However, hemorrhoids can recur over time, mainly if the underlying causes, such as chronic constipation, straining, or prolonged sitting, are not addressed.

Most patients require a series of IRC treatments, spaced a few weeks apart, to fully resolve their symptoms. After that, maintaining a high-fiber diet, staying hydrated, safe laxatives recommended by our gastroenterology team, and using the bathroom when the urge strikes can help prevent recurrences.

What happens after the IRC is done?

After your IRC treatment, you can return to your usual routine almost immediately. Some patients may experience mild rectal pressure, a feeling of fullness, or spotting of blood for a few days after the procedure. These symptoms usually improve quickly without intervention.

You’ll want to avoid heavy lifting or intense physical activity for 24 hours. It’s also a good idea to continue taking a fiber supplement and drinking plenty of water to keep your stools soft. Your NYGA provider may schedule a follow-up visit to assess your progress and determine whether additional treatments are needed.

If you’re dealing with persistent hemorrhoid symptoms and looking for a fast, effective treatment without surgery, infrared coagulation may be the right choice. NYGA’s team of gastrointestinal experts can evaluate your symptoms and develop a personalized plan to bring lasting relief.
