Internal vs. External Hemorrhoids: How the Location Affects Treatment

Posted on September 15th, 2026

Where a hemorrhoid develops affects your symptoms and which treatments are appropriate. At Piedmont Colorectal Associates in Atlanta, GA, our board-certified colorectal surgeons diagnose and treat internal and external hemorrhoids, tailoring treatment to the location, severity, and impact of your symptoms.

What Makes a Hemorrhoid Internal or External?

The distinction comes down to anatomy. Internal hemorrhoids develop inside the rectum, above an area called the dentate line. Because this region has fewer pain-sensitive nerves, internal hemorrhoids commonly cause painless, bright-red bleeding during bowel movements. As they become larger, they may also protrude or prolapse through the anus. External hemorrhoids form beneath the skin around the anus, where many more pain-sensitive nerves are present. They may cause itching, irritation, swelling, or tenderness. If a blood clot develops inside an external hemorrhoid (a condition called a thrombosed hemorrhoid), the resulting lump can become particularly painful.

How Are Internal Hemorrhoids Treated?

Mild internal hemorrhoids may improve with more fiber and fluids, better bowel habits, and avoiding straining or spending too much time on the toilet. When symptoms persist, office-based procedures may be considered. Rubber band ligation is one common option for symptomatic internal hemorrhoids. A small band is placed around the hemorrhoidal tissue, restricting its blood supply so the tissue eventually shrinks. Other approaches may include sclerotherapy or infrared coagulation. Current colorectal surgery guidelines consider banding the most effective office-based treatment for many grade I and II hemorrhoids and select grade III cases.

Why Are External Hemorrhoids Treated Differently?

Because external hemorrhoids are covered by highly sensitive skin, treatments designed for internal hemorrhoids are not necessarily appropriate for them. Mild symptoms may be managed conservatively with dietary changes, improved bowel habits, and measures to reduce irritation. Treatment may change when an external hemorrhoid becomes thrombosed, or symptoms are severe. Select patients with thrombosed external hemorrhoids may benefit from early surgical excision, while excisional hemorrhoidectomy may be recommended for certain patients with significant external disease or combined internal and external hemorrhoids.

Why an Accurate Diagnosis Matters

Bleeding, pain, itching, and anal lumps are not always caused by hemorrhoids. Anal fissures and other colorectal conditions can produce similar symptoms, and rectal bleeding should not automatically be assumed to come from hemorrhoids. A colorectal evaluation can identify the source of your symptoms and determine whether you have internal hemorrhoids, external hemorrhoids, both, or another condition entirely. At Piedmont Colorectal Associates, specialized colorectal experience lets us base treatment on your anatomy and symptoms rather than a one-size-fits-all approach. If hemorrhoids are interfering with your comfort or daily routine, contact us at (404) 351-7900 to schedule an evaluation in Atlanta.
