Anal Leakage (Leaky Anus): Causes, Symptoms and Effective Treatments

Anal Leakage (Leaky Anus): Causes, Symptoms and Effective Treatment

Having a leaky anus can be an embarrassing condition whereby a person passes some stool or anal discharge unexpectedly or uncontrollably. The most common reasons for anal leakage are diarrhea or constipation, in which case the leakage will usually stop when your digestive system gets back to normal. However, leakage from the anus can also happen if you have hemorrhoids, damaged rectal muscles, or nerve damage. In these cases, the leaky anus could be a chronic condition that requires proper medical care and management.

Anal leakage is sometimes called bowel incontinence, fecal incontinence or anal seepage. Some people only realize that they suffer from a leaky anus when they notice anal discharge on their underwear. The seepage may be watery stool or mucus that has passed unknowingly from the rectal muscles. Other people experience urge incontinence, where the urge to pass stool is so strong and sudden that they don’t manage to go to the toilet in time.

Depending on the reasons for bowel incontinence, there are different ways to treat a leaky anus. Some natural remedies to stop anal seepage help to treat the underlying digestive condition like constipation or diarrhea. Other cures for anal leakage require medical supervision to address the underlying medical cause. For example, in some cases, anal and pelvic exercises can strengthen the muscles in the rectum to hold stool until you get to the toilet.

The good news is that in most cases it is possible to stop stool leaking from the rectum and you can regain your confidence to care for your daily activities without any worry.

What is a Leaky Anus (Anal Leakage)?

The nerves and muscles in the anus and rectum work together to hold feces in the bowels. When the rectum is full, nerves send a signal to the brain that it is time to get rid of the stool. However, anal leakage occurs when either the anal muscles or nerves don’t work properly.

According to doctors at the Mayo Clinic, bowel incontinence can be broken down into two types:1

  • Passive bowel incontinence. A person isn’t aware that they have passed stool and may only realize when they change their underwear. A person may also experience leakage from the anus when they pass gas.
  • Urge incontinence. This is a sudden urge to pass stool and the person doesn’t make it to the toilet in time. This can result in the whole bowel movement happening in the person’s clothing.

Causes and Symptoms of Anal Leakage (Anal Seepage)

There are many reasons for anal leakage and usually, it’s possible to find effective ways to treat the underlying cause of bowel incontinence. It’s important to find why your rectum can’t retain stool to know the best way to treat the condition.


Constipation or impacted stool is a very common reason for having a leaky anus (anal leakage). Constipation can also cause pain in the lower left area of the abdomen as well as a lower back and stomach pain.

According to the National Health Service in the United Kingdom, impacted feces stretch the muscles of the rectum. This allows watery stools or mucus to leak past the hard stool and then accidentally pass out through the rectum.2


There are many reasons why a person can suffer from diarrhea and it is a common cause of anal leakage.

The Mayo Clinic says that, in some people, the rectal muscles can’t hold watery stools very well. Therefore, the loose stools leak easily and can cause bowel incontinence.1 The anal discharge can also happen involuntarily when a person passes gas.

There are also a number of underlying health conditions that can cause diarrhea which might be a reason for experiencing anal seepage. Here are some of the most common reasons for diarrhea that causes anal leakage:

  • Inflammatory bowel disease (IBD). Dr. Carol DerSarkissian on WebMD says that Crohn’s disease or ulcerative colitis can be a reason for frequent bouts of diarrhea.3 This could also cause anal leakage to happen during the night if you sleep through the urge to use the bathroom. These inflammatory bowel diseases can also lead to leaking mucus or blood from the rectum.
  • Gastroenteritis. Viruses or bacteria can infect the digestive tract and cause severe diarrhea and vomiting after eating and leaking a small amount of stool.
  • Irritable bowel syndrome (IBS). Another reason why you could pass stool unexpectedly because of diarrhea is having irritable bowel syndrome.


Hemorrhoids (piles) are swollen blood veins around the lower part of the rectum. They can cause pain, itching, bleeding and discomfort around your anus. According to Dr. Benjamin Wedro on MedicineNet, anal leaking can occur if the hemorrhoid is inflamed.4

Damage to the sphincter muscles

Any kind of damage to the muscles in your lower rectum can cause accidental bowel leakage. There are a number of reasons why the muscle damage occurs in the anus. Some of the most common reason why damaged muscles can’t prevent involuntary anal leaking are:

  • Damage to the sphincter muscles during childbirth when the muscles become stretched or damaged
  • Prostate or rectal surgery or radiation treatment
  • Some kind of trauma to the anal region
  • In some cases, inflammatory bowel disease can also cause damage to the muscles in the rectum5

Nerve damage

Passing or leaking a small amount of stool without realizing it can be caused by nerve damage. The fecal soiling happens because the nerves don’t control the opening and closing of the sphincter muscles properly. Some common reasons for anal leakage caused by nerve damage are:

  • Childbirth
  • Frequent and long-term straining to pass impacted stool
  • Diabetes
  • Multiple sclerosis
  • Stroke
  • Alzheimer’s disease

Treatments for Anal Leakage

Passing stool or anal discharge unexpectedly or having a bowel movement in your underwear because you couldn’t make it to the toilet in time can be a traumatic experience. However, with the right treatment and medical management, you should be able to successfully treat the bowel leakage.

How to treat anal leakage caused by constipation

To prevent anal seepage which is caused by constipation and make your bowel movement regular, it’s important to make sure that you eat the proper kinds of foods.

Studies into treating fecal incontinence suggest eating the right amount of fiber and drinking plenty of water if you have constipation.7

Eat fiber. If you suffer from constipation, it’s important to consume the right amount of fiber in your diet. Fiber helps the digestive system to work properly and soften stools. Director of Nutrition at WebMD, Dr. Kathleen M. Zelman recommends high-fiber foods like whole grains (e.g. brown rice, wholemeal pasta, and whole-wheat bread), nuts, beans, popcorn, and berries as great sources of fiber.

Drink lots of water. Water helps fiber to improve the way your digestive systems works. So, make sure and drink at least 8 glasses of water a day to help fiber soften impacted feces to prevent anal leakage. Drinking enough water is a great way to keep your body healthy.

You will find out how coconut oil, probiotics, castor oil, and dried fruit can help to get relief from impacted stools and thus help to resolve a leaky anus.

Anal leakage from diarrhea

Having diarrhea is bad enough, but if the watery stool also seeps out without you realizing it, it can cause even more emotional discomfort. There are many natural remedies for diarrhea that help to reduce inflammation in your digestive tract and prevent anal leakage.

If you have diarrhea, it’s important to limit your intake of insoluble fiber (whole grains, beans, nuts, etc.) and increase your intake of soluble fiber (peas, bananas, carrots, apples, and oats) to help manage a leaky anus successfully.7

Ginger. Ginger is a wonderful therapeutic root that has many health benefits. One of best uses for ginger is to calm gastrointestinal cramps and inflammation. Studies into ginger have shown that it’s a beneficial natural ingredient to calm stomach cramps.8

You can make a delicious tea by grating a 1-inch piece of ginger and letting it steep in a cup of boiling water for a few minutes. Drink the tea 2-3 times a day to help reduce inflammation in your digestive tract and cure anal seepage.

Chamomile tea. Chamomile is a calming herb that works to soothe the mind and your digestive system. Studies into the effects of chamomile tea in the treatment for diarrhea have shown extracts of the herb can help to relieve diarrhea and stomach pain.9

Probiotics. Probiotics may help to reduce anal leakage because they improve both the symptoms of diarrhea and constipation. Research into using probiotics for digestive issues have found that they effectively reduce symptoms of diarrhea caused by taking antibiotics, viruses, and bacterial infections.10

Lifestyle Changes to Stop Anal Leakage

If you suffer from chronic or recurrent anal leakage, you may have to make some lifestyle changes to stop leaking stool on your underwear. Some of these lifestyle changes for treating a leaky anus include:7

  • Avoiding foods that cause gas and bloating if these cause any kind of seepage from the anus.
  • Avoiding spicy and fried foods as well as caffeinated drinks if they aggravate bowel incontinence.
  • Avoiding milk products that contain lactose to stop diarrhea and inflammation in the digestive system.
  • Drinking enough water to keep bowel movements regular.

Leaky Anus Caused by Muscle Damage

If your leaky anus has been caused by muscle damage, your doctor may suggest a series of anal and pelvic exercises to help strengthen the muscles. When your muscles are stronger, they can hold in stool and loose fecal matter more effectively.

Dr. Adam Husney on WebMD recommends Kegel exercises to strengthen pelvic muscles to prevent bowel incontinence. For more information on Kegels and practical advice on how to perform them, I have written an article on why Kegel exercises are so beneficial for strengthening your pelvic area.

Anal Leakage – Get Advice from your Doctor

As you can see, there are a number of reasons for suffering from a leaky anus and there are also a number of possible treatments. However, only a medical practitioner can determine the exact cause of the problem and suggest the most effective treatment.
