You clean, you wipe, you shower, and yet your bum still smells likes poop.

You may ask, is it normal for your bum to smell this way? No, it’s not, but unfortunately, it is common enough for a lot of people to be suffering from it and actively looking for solutions to it, including you.

Here are the most common reasons why your butt smells even after washing:

  • Not Wiping / Cleaning Properly
  • Excessive Butt Sweat (“Swamp Ass”)
  • Excessive Flatulence / IBS / Bad Diet
  • Hemorrhoids
  • Constipation
  • Sexually Transmitted Infections (STIs)
  • Abscesses
  • Muscle Problems

I will explain each of these in more detail below. My advice is to look through the titles, see which applies to you, and quickly look over them, as well as the recommended fixes.

Hopefully, this will help narrow down your specific cause and allow you to fix the problem.

Not Wiping / Cleaning Properly

For most people, this (along with IBS and a bad diet) is likely to be the biggest cause.

Basically, that bad smell coming from your butt is oftentimes simply the result of not wiping properly or using the wrong things to wipe or clean after taking a poop. 

Another reason for butt smell could be that there is still fecal matter (which isn’t always visible by the way) around the outside and just inside your anus area.

It is extremely difficult to wipe everything up using only dry tissue paper, which is why I am suggesting the following solutions below, to at least eliminate this as a possible cause of your smelly butt.

Use Wet Wipes

Instead of just using dry toilet paper, use wet wipes first and then use toilet paper after, particularly the unscented ones; the reason for this is that some scented wipes can cause irritation down there, which can make your butt smell even worse.

Imagine you got poop all over your arms, legs, or wherever. Would you feel clean if you just wipe it off with toilet paper? Of course not, right? You would probably want to wash it off with water and even use soap or alcohol to get rid of the smell and to make sure it’s clean.

But if you’re not a fan of washing your butt after pooping, then I would recommend at least use wet wipes. Most wipes are made of non-woven fabric similar to those used in dryer sheets, which are then saturated with a solution of water and gentle cleansing agents such as isopropyl alcohol. 

After pooping, use wet wipes first to properly clean your butt. Then, to make sure that it’s dry, use some normal toilet paper afterward. Make sure to wipe from front to back, moving fecal matter away from your front parts.

Get a Bidet

A better alternative to wet wipes is to just get a bidet. It is the cleanest, healthiest, and most hygienic way to clean your butt of any remaining fecal matter and any smelly bacteria. A gentle stream of water thoroughly rinses your butt area without causing irritation.

Even if you take a shower, your butt could still smell bad if you’re not cleaning it properly. Using a bidet will allow you to target the area around your anus so you can completely clean it out. Afterward, don’t forget to dry off by using toilet paper.

I recently discovered the Tushy Classic 3.0 Bidet Toilet Seat Attachment, which I think is a quick and affordable way to give your butt the clean it deserves. It easily attaches to any standard toilet in under 10 minutes so this is definitely a good option.

Consider Removing Butt Hair (If You’re Overly Hairy) 

We all know that hair tends to trap bacteria and odors. Since poop comes out of our butthole, then it is possible that some of the fecal matter gets stuck in our hair down there, especially if we’re not washing/cleaning properly, as I previously outlined above.

While butt hair may not necessarily be the cause of butt smell, it is certainly not helping it smell good either. For this reason, it may be good to consider removing it all, through waxing or just trimming, whatever you prefer.

If you plan on waxing, then I would personally recommend the VidaSleek Wax Kit for Men & Women. If you want more information about this topic, I tackle this in more detail in my other article. Feel free to check it out here.

Excessive Butt Sweat (“Swamp Ass”)

Swamp ass. Sweaty bum. Butt sweat. Whatever you want to call it. This happens to everyone. A hot summer day, an intense day at the gym, stress, or even something medical-related can cause your butt to sweat so much that you’ll feel like you’ve been sitting in a swamp.

Remember that sweat in itself is not supposed to smell bad. In fact, it should actually be odorless. It is when you mix it with bacteria that it starts to develop an odor, an unpleasant one at that.

The thing is, your bum is an absolute breeding ground for bacteria:

  • It’s Dark
  • Warm
  • Moist

Plus, if you’re not cleaning your butt properly, chances are there will be some remains of fecal matter down there as well. Together, these three can lead to a very unpleasant odor in your butt area.

Wear Breathable and Non-Synthetic Underwear

Have you tried changing the types of clothing and underwear that you put on every day?

A lot of people aren’t aware of this, but this can have a big effect on how much moisture your bum produces, which in turn affects how easier it is for your butt to start smelling bad again, as I discussed above.

If you can reduce the amount of warmth and moisture in your butt area, you can eliminate more bacteria, and thus reduce unpleasant odors. Here’s how:

  • Wear breathable underwear; something that is less restrictive, boxers are a good option, as are boxer shorts.
  • Natural fabrics like cotton allow your skin to breathe and may be a good choice in terms of fabric type. By contrast, synthetic fabrics like nylon and polyester are especially non-breathable and could potentially amplify the smell coming out of your bum.

Use Body Powder for Your Butt

Body powders are extremely useful in mitigating and preventing sweat, bad body odors, as well as skin chafing and irritation. I personally use these mostly for my balls, but these can also easily be used for your bum.

I love the Chassis Premium Body Powder, which is talc-free and has a very light scent (mix of Old Spice + pumpkin). For women, I think the Fromonda (Cool Mint) Body Powder (also talc-free), is an excellent option.

There’s no shame in using a little powder down there as no one will be able to tell you’re using it but you, anyway. Plus, you will feel much cleaner and more comfortable since you’re producing less sweat.

Excessive Flatulence / IBS / Bad Diet 

This is right up there with improper wiping as a major cause of a bad-smelling bum.

Now, just because you don’t pass excessive gas, doesn’t mean you should just skip over this section. Read through and see if anything below applies to you.

I lumped all of these together because they more or less are all related.

Here’s why:

  • Excessive farting; flatulence comes from hydrogen sulfide that is released from your gut due to the digestion process; if you are passing gas more than normal (nearly every hour), this could be a cause.
  • Gluten sensitivity could also be a cause; this is where your stomach has a difficult time processing gluten; it simultaneously also produces a lot of gas.
  • Lactose-intolerance; is more prevalent in certain ethnicities, such as those who can trace their ancestry to Africa, Southeast, and East Asia.
  • Too much sugar in your diet; can affect the walls of your colon, restricting their ability to close and possibly making the area more “inducive” towards bacterial growth.

In order to eliminate one of these as the possible cause of your foul smell, here are some steps you can take:

  • Reduce your sugar intake.
  • Take a digestive enzyme (which you can find at a local store); these help your stomach and digestive system break down larger food particles.
  • Take a probiotic; this will help you maintain a good balance of healthy bacteria in your gut.
  • Eat slower; when you eat too fast you also swallow air, this, in turn, makes you pass more gas, which in turn leads to a smellier butt.


Chances are, if you had hemorrhoids, you would know but did you also know if you have a recurring problem with them, it could be the cause of the bad smell of your butt?

Hemorrhoids, for those that don’t know, are ruptured or strained blood vessels in and around your behind.

They typically occur when you are on the toilet and straining too much.

You would know you would have them as they are uncomfortable and often painful, especially when you pass another stool when you wipe, and sometimes even when you move.

If this is you, over-the-counter hemorrhoid medication can eliminate these.


Chances are, this probably won’t apply to you, but it still bears mentioning.

Constipation typically occurs when you don’t get enough fiber in your diet, which affects the regularity with which you take a poop.

The more poop that gets “blocked up” up there, means that this could result in a bad smell from your butt.

If this was a problem, you would know it.

You can fix this through OTC medication and proper dieting..

Sexually Transmitted Infections (STIs)

Have you considered this?

Millions of people every year are unaware that they have STIs, and while just about everyone knows that STIs can affect the physical appearance of your private region, did you know that they can also affect your smell?

Here’s the lowdown on this:

  • HIV, chlamydia, gonorrhea, syphilis, herpes, and HPV not only can infect your private parts, it can also infect your butt; if this happens, it could be producing that nasty smell.
  • If left untreated, it can go unnoticed, but could also be the cause.
  • Take an STI test, make sure that you are all clear, and eliminate this from any possible causes.


Here’s where things start to get more complicated, because these are not visible, and aren’t as easy to fix as something like hemorrhoids.

Now, personally, I wouldn’t consider something like this as a possible cause, unless I first went through and eliminated any of the above, easier to fix possible causes. 

An abscess is basically like a little pocket full of pus and body fluid, that collects and swells.

These can also occur in your bottom.

Here’s what happens:

  • You unknowingly have an abscess around the anus or rectum area.
  • Poop clogs the glands in and around the abscess.
  • This then turns into an infection.
  • The abscess’ mixture of pus, body fluid, and poop all mix to form a vile odor that comes out regardless of how many times you wash and scrub.

Unfortunately, the only real way to know if this could be causing your odor is through a check with a gastrointestinal doctor.

Muscle Problems 

Like an abscess, this can go unnoticed, though not to the same degree.

What could be happening is:

  • The muscles around your butt do not work properly, are strained or injured in some way, and do not allow your behind to properly close.
  • Because your butt is not fully closed, stool odors seep through much more easily.

As with abscesses, the best way to eliminate this as a cause would be to book an appointment with a doctor and have him or her take a look.


Hopefully, this article helped, or at least narrowed down some of the possible causes of that bad smell emanating from your butt.

To recap, here’s what you should do to identify why your but smells and the actions you can take to get rid of the bad smell permanently (hopefully):

  • Wipe your butt properly using wet wipes. Better yet, get a bidet. 
  • Wear breathable, loose-fitting underwear.
  • Apply body powder or a body spray, if you haven’t already, to reduce butt sweat.
  • Eliminate too much sugar from your diet, take a probiotic and digestive enzyme.
  • Book an appointment with a doctor to ensure that the butt smell is not medical-related (i.e. constipation, hemorrhoids, or STDs).
