Hemorrhoids rarely cause bowel incontinence on their own, but they can contribute to it

Hemorrhoids are swollen blood vessels in or around the anus. They can bleed, itch, and cause pain, but they do not directly damage the muscles and nerves that control bowel movements. However, severe hemorrhoids—especially internal ones that prolapse, or slip outside the body—can weaken the anal sphincter (the ring of muscle that holds stool in) over time. This weakening may make it harder to hold stool, particularly during flare-ups when hemorrhoids are inflamed and painful.

The connection is usually indirect. Pain from hemorrhoids can make you tense the sphincter muscle constantly to avoid discomfort, which eventually fatigues the muscle. Bleeding or mucus discharge from hemorrhoids can also trigger false urges to have a bowel movement, which some people confuse with incontinence. If you have both hemorrhoids and leakage, the hemorrhoids may be part of the picture, but other causes—such as nerve damage, muscle weakness, or inflammatory bowel disease—are often involved as well.

Key Takeaways

  • Hemorrhoids themselves do not cause incontinence, but severe or prolapsing hemorrhoids can gradually weaken the anal sphincter muscle over months or years.
  • Pain and discharge from hemorrhoids can create the sensation of needing to go urgently, which is different from true loss of stool control.
  • If you have both hemorrhoids and incontinence, a doctor should evaluate you to identify all contributing causes, not assume one is causing the other.
  • Treating hemorrhoids—through diet, hydration, topical creams, or medical procedures—may improve comfort but will not reverse sphincter damage that has already occurred.
  • Pelvic floor physical therapy can strengthen the sphincter muscle regardless of whether hemorrhoids are present.

How hemorrhoids affect the anal sphincter

The anal sphincter is made up of two muscles: an inner one you cannot control and an outer one you can squeeze voluntarily. When hemorrhoids are large or prolapse, they can physically stretch and irritate these muscles. Over time, repeated stretching weakens the muscle fibers, making it harder to maintain a tight seal.

This process usually takes months or years, not days or weeks. A single hemorrhoid flare-up will not cause incontinence. But if you have chronic hemorrhoids that bleed frequently or prolapse regularly, the cumulative effect on the sphincter can become noticeable. The risk is higher if you also have other risk factors for incontinence, such as age, childbirth history, or chronic straining.

The difference between hemorrhoid symptoms and incontinence

Hemorrhoids produce several symptoms that can feel similar to incontinence but are actually separate problems. Bleeding or mucus discharge can soil underwear, which feels like leakage. Urgency—a sudden, strong urge to have a bowel movement—can make you rush to the toilet, and if you do not make it in time, you may leak stool. But this is different from the inability to feel or hold stool, which is true incontinence.

Hemorrhoid-related urgency usually happens during or right after a flare-up, when the hemorrhoid is inflamed and irritating the nerve endings in that area. Once the flare-up settles, the urgency often improves. True incontinence from sphincter damage is more constant and does not improve just because the hemorrhoid feels better.

When hemorrhoids and incontinence occur together

If you have both hemorrhoids and incontinence, it is important not to assume one is causing the other. Many people have hemorrhoids without any incontinence, and many have incontinence without hemorrhoids. When both are present, they may be unrelated, or they may share a common cause.

For example, chronic straining during bowel movements can cause both hemorrhoids and pelvic floor dysfunction (weakness of the muscles that support continence). Inflammatory bowel disease, such as Crohn's disease or ulcerative colitis, can cause both hemorrhoids and diarrhea-related incontinence. Childbirth can damage the sphincter muscle and also increase the risk of hemorrhoids later. A doctor can help sort out which condition is which and whether they are connected in your case.

What treatment options exist

Hemorrhoid treatment ranges from self-care to medical procedures. Over-the-counter creams and suppositories can reduce itching and pain. Increasing fiber and water intake, and avoiding straining, can prevent new hemorrhoids and allow existing ones to shrink. Sitz baths (sitting in warm water for 10 to 15 minutes) ease discomfort during flare-ups.

If hemorrhoids are severe or do not improve with self-care, a doctor may recommend rubber band ligation (placing a small band around the hemorrhoid to cut off its blood supply), sclerotherapy (injecting a chemical to shrink the hemorrhoid), or surgical removal. These procedures can reduce hemorrhoid symptoms and may improve comfort during bowel movements, but they will not reverse sphincter muscle damage that has already happened.

If incontinence is also present, treatment depends on the cause. Pelvic floor physical therapy—exercises to strengthen the sphincter and surrounding muscles—can help whether or not hemorrhoids are involved. A doctor may also recommend dietary changes, medications, or other approaches based on what is causing the leakage.

When to see a doctor

See a doctor if you have hemorrhoids and are also experiencing stool leakage, especially if the leakage is new or worsening. Do not assume the hemorrhoids are the cause. A healthcare provider can examine you, ask about your symptoms, and run tests if needed to identify all the factors at play.

Mention how long you have had hemorrhoids, how often they flare up, whether you strain during bowel movements, and whether the incontinence happens all the time or only during hemorrhoid flare-ups. This information helps your doctor understand whether the two conditions are connected or separate.

Frequently Asked Questions

Can hemorrhoid surgery fix incontinence?

No. Removing hemorrhoids will not restore sphincter muscle function if that muscle has been damaged. However, surgery may reduce pain and urgency, which can make it easier to manage incontinence. If incontinence persists after hemorrhoid treatment, you will need separate treatment for the sphincter weakness.

Do hemorrhoids cause mucus leakage?

Yes, hemorrhoids often produce mucus discharge that can soil underwear. This is not the same as stool incontinence, but it feels similar. The mucus usually stops once the hemorrhoid flare-up improves with treatment.

Can I have incontinence from hemorrhoids without any other cause?

Incontinence from hemorrhoids alone is uncommon and usually only happens if the hemorrhoids are very large and have been present for a long time. Most people with incontinence have multiple contributing causes, so a full evaluation is important.

Will treating my hemorrhoids improve my incontinence?

Treating hemorrhoids may reduce urgency and discomfort, which can make incontinence easier to manage. But if the incontinence is caused by sphincter muscle weakness, you will likely need specific treatment for that weakness, such as pelvic floor physical therapy.

What is the connection between straining and both hemorrhoids and incontinence?

Chronic straining during bowel movements can weaken the pelvic floor muscles over time, leading to both hemorrhoids and incontinence. Addressing the underlying cause—such as constipation or a low-fiber diet—can help prevent both conditions from worsening.
