Flatulence, also known as a fart, is something everyone experiences. It’s the release of intestinal gas, which forms as a result of digesting food. Gas can be found throughout the digestive tract, including the stomach, small intestine, colon, and rectum.

We fart because of the buildup of gas in our bodies, typically due to:
  • Swallowed air: We swallow air throughout the day, including from carbonated beverages or taking in air as we chew.
  • An overgrowth of bacteria in the small intestine: Several conditions can lead to bacteria overgrowth, including type 2 diabetes, celiac disease, liver disease, and inflammatory bowel disease.
  • Carbohydrates that haven’t been fully digested: Sometimes all your food doesn’t get fully digested by the enzymes in the small intestines. When partially digested carbs reach the colon, bacteria convert part of that food into hydrogen and carbon dioxide gasses.

All that gas has to go somewhere. Some of it can be absorbed by the body. But when too much of it gathers in the upper part of your colon and puts pressure on the colon wall, you can feel pain in your abdomen or even all the way up into your chest. Flatulence, though, allows for a painless means of escape for this gas.

Why do I fart so much?

Sometimes you may experience more flatulence than usual. Increased farting can stem from a natural body reaction, or in some cases, an underlying medical condition. Factors that can affect how much you fart include:

Time of day

A buildup of gas-producing foods and swallowed air during the day may make you more flatulent in the evening. Also, you’re more likely to fart when the muscles in the intestines are stimulated. When you’re about to have a bowel movement, for example, those muscles are moving stool to the rectum. But other activities can also trigger flatulence, such as exercise or even coughing.

Certain foods

Foods ranging from beans to broccoli to bran can make some people gassier. Foods don’t affect everyone the same way, though. You may know your troublesome foods, so be aware of them if you’re concerned about being gassy. You may also be among the many people who lack the enzyme lactase, which is essential for properly digesting dairy products. You can be born with this lactose intolerance or it could develop as you age.


Alongside the amazing changes your body goes through when you’re pregnant, there are some unpleasant changes, such as increased gas production. This change is the result of increased hormonal activity that tends to slow down your digestion, allowing more gas to build up in your intestines.


Hormonal changes during your period can also coincide with bacteria changes in your digestive tract that can sometimes lead to increased flatulence.

Medical conditions

Diseases of the digestive tract may cause you to produce more gas. Surgery that affects the intestines could result in bacterial overgrowth there, and the subsequent production of more intestinal gas.

How can I stop farting so much?

Preventing increased gas may be as simple as adjusting your diet. If you’re lactose intolerant, your doctor will advise you to avoid milk-based products. Using a lactase supplement that provides the enzyme to make digesting dairy easier may also be an option.

To decrease your gas, you may want to stop drinking carbonated beverages.

If you’re especially sensitive to beans or other common culprits, eating smaller portions or swapping them out for other healthy foods may be options for you. Be careful not to suddenly boost your fiber intake, as that can also cause gas problems.

When is gas a problem?

The average person farts about 15 times per day, though you may pass gas much more or less frequently. You may be unaware of much of this activity because you’re asleep or the gas release is so minor.

But if you experience excessive flatulence, you should see a doctor. It could mean you have a gastrointestinal problem. You definitely shouldn’t hesitate if you also experience painful cramps, bloating or other symptoms. Conditions such as irritable bowel syndrome, Crohn’s disease, celiac disease, lactose intolerance, and peptic ulcers are all associated with excessive gas other unpleasant symptoms.

When your body builds up excess gas inside your digestive system, there are only two places it can come out and one of those happens to be your bottom. This process of passing gas is better known as farting.

The gas that causes farting (and also burping) builds up normally during digestion and also when you swallow air along with your food while eating or drinking. This gas can build up faster if you smoke, use a straw , or eat foods that are hard to digest. You might also be gassier if you are stressedconstipated, or have a medical condition affecting the digestive system. Gas can cause bloating and discomfort. Farting is a healthy way of releasing gas from your body.

Farting is totally natural and everyone’s body does it. Most people fart five to 23 times per day.

Some may feel embarrassed or uncomfortable if they fart more often, have uncomfortable or smelly farts, or have to fart in public. Some people try to hold in farts until either they feel safe enough to let them out or the gas uncontrollably escapes.

While research on farting is limited, some studies suggest holding it in might not be good for us and that it’s much healthier to just let them out.

Is it bad to hold in farts?

There is limited scientific evidence that holding in farts could cause several health issues.

In the short term, holding in a fart can cause immediate:

  • pain
  • discomfort
  • bloating
  • indigestion
  • heartburn

What’s more, as the pressure builds, so may your stress levels, making it even more uncomfortable and less likely you’ll be able to hold in a fart.

In the 1970s, experts found that a habit of holding in farts could be associated with the development of diverticulitis. This is the inflammation or swelling of pouches that form along the digestive tract. Diverticulitis can be severe and can cause infection if left untreated. However, without more and more recent research, a clear link between holding in farts and diverticulitis cannot be made.

Can you die from holding in a fart?

There is no evidence that holding in a fart could kill you, though the pain and discomfort doing so causes can be severe.

What happens when you hold in a fart?

When you fart, gas moves from your intestines into your rectum, and then leaves through your anus. But if you tighten your anal sphincter muscles (the muscles you might also tighten if you’re holding in a bowel movement) by clenching your buttocks, you can usually hold in a fart for a period of time.

After tightening your sphincter muscles, the pressure will start to build on the gas in your digestive system. You may experience some of the short-term symptoms of holding in a fart, including pain, bloating, and discomfort. You may feel some bubbling or gurgling as the gas moves around your digestive system.

Research shows that some of this gas is reabsorbed by your body’s blood system and may eventually be let out when you exhale. However, the majority of the gas will remain under pressure inside of you until you’re finally able to release it through a fart or burp, or both.

How to prevent farts from forming

You won’t need to hold in gas if you can get rid of the need to fart in the first place.

Since intestinal gas is usually caused by digestion, it can help to take a look at your diet.

Elimination diet

Take one of these common gas-causing foods out of your diet at a time and see if you fart less:

  • dairy
  • beans and legumes
  • Brussels sprouts
  • lettuce
  • cauliflower
  • sugar-free foods (which contain sorbitol, mannitol and xylitol)
  • cabbage
  • onions
  • broccoli
  • mushrooms
  • beer
  • carbonated drinks

Balanced diet

Reduce the amount of fatty and high-protein foods in your diet, which take more time to digest and may cause more gas.

Reduce the fiber in your diet. While high-fiber foods like whole-grain breads, bran and nuts are healthy, they can also cause a lot of gas. If you feel less gassy after cutting back, slowly introduce more fiber back into your diet.

Avoid hard candy and chewing gum.

OTC medication

Take an over-the-counter gas medication before eating foods with lactose.

Lifestyle changes
  • Eat and drink slower so you swallow less air.
  • Eat smaller and more frequent meals to reduce stress on your digestive system.
  • Exercise regularly, as this can help move gas out of your digestive system
  • Don’t smoke. This can be difficult but a doctor can help build a cessation plan that works for you.
  • If you wear dentures, make sure they fit properly.
  • Treat underlying medical conditions like IBS and heartburn that may cause gassiness.

How to hold in a fart safely

Sooner or later, the gas will come out. Doctors don’t have medical advice for holding in farts, which requires you to hold your sphincter muscles the same way you’d hold in a bowel movement.

However, it seems that if you can hold in a fart without feeling too much discomfort, you might be able to let it seep out quietly by applying light pressure to your sphincter muscles. Or by holding your fart, you might buy yourself enough time to make it to a bathroom or other private place.

When farting poses health risks

Rarely is farting a sign of a serious medical condition. However, excessive farting (more than 25 times a day) or extremely foul-smelling farts may be a sign of an underlying cause.

If you’ve tried to prevent your farts without success and notice any of the following symptoms, you should speak to a doctor.

The most common conditions associated with farting are digestive and eating disorders, food intolerances and cancer. Most of these conditions respond well to treatment.

Bottom line:

When it comes to farts, the healthiest thing to do is let them out. However, it is possible to hold them in if you need to, and it probably won’t hurt you. Just be prepared for some discomfort.

If you notice you are farting excessively and have other symptoms of digestive distress, you should see a doctor. Most health issues associated with farting can improve with proper treatment.

Can Holding Fart Leak Out Your Mouth?

Nearly everyone has been in a situation where passing gas would be embarrassing. Choosing to “hold in” or delay flatulence from escaping is often the polite thing to do. But holding in a fart for too long isn’t good for your body.

If you decide not to release a fart, some of the gas will be reabsorbed into the circulatory system. From there, it goes to the lungs for a gas exchange throughout the pulmonary circulation system and is expelled through breathing.

While this isn’t a “mouth fart,” per se, it’s the gas from the fart coming out of your mouth.

So how often does this really happen? And can holding in flatulence all the time hurt your body in the long run? Let’s cover all of that and more.

How holding in a fart can lead to gas coming out of mouth  

Farts, also called flatus, are a natural part of your digestive process. Bacteria in your intestines create gases as they break down and metabolize the food that you eat. These gases expand your colon, giving you a feeling of fullness and discomfort. The gas needs a place to escape, and usually, it’s through your rectum.

When you block a fart from escaping, some of the gas can pass through your gut wall and be reabsorbed into your bloodstream. From there, it can end up being exhaled through your lungs, coming out of your mouth via exhaling.

Can you taste a fart in your mouth?

You won’t be able to taste a fart that escapes through your mouth.

Flatulence is made up of swallowed air and gas produced by bacteria in the colon from undigested carbohydrates. It smells bad due to the breakdown of various foods into certain gases, primarily sulfur-containing gases. These aren’t reabsorbed by your body.

Other side effects of holding in gas

Gas escaping through your mouth isn’t the only possible side effect if you try to hold flatulence in.

Bloating and belching

Swelling and bloating in your abdomen can be caused when you’re gassy and deny that gas an exit. A bloated belly can make you more prone to belching.

Pain and swelling

When you have a lot of gas, you may feel uncomfortable. But trapping the gas in your body by holding in a fart can take that discomfort to the next level. Cramping and pain can occur from holding in flatulence.


If you regularly hold in flatus, it’s possible that air pockets will begin to form inside of your digestive tract. If these pockets become infected or inflamed, you can develop the digestive condition diverticulitis.

Should you fart in someone else’s mouth?

If gas that is a part of flatulence is making its way out of your mouth, anyway, does that mean it’s OK to fart into someone else’s mouth?

Well, it’s not proper custom unless you’re a young child, but it won’t cause pinkeye, spread a virus or cause giardia, an infection of the digestive tract that’s caused by a parasite.

All three of those are commonly spread myths.

It has no medical side effects because flatus only contains gas. There shouldn’t be any fecal particles in it. The spread of fecal particles is necessary to cause any of the conditions above.

Bottom line:

Holding in your flatulence can feel necessary out of common courtesy, but don’t make it a habit when you don’t have to hold it in. Gas from your intestines will get out one way or another, even if it has to travel back into your bloodstream and escape through you mouth.

Why do my farts smell so bad?

Flatulence, which is sometimes called passing wind, passing gas, or farting, is a biological process that helps to release gas from digestion. Though in some cases they are silent and odorless, farts can become uncomfortable when they are loud and foul smelling.

Smelly gas is not uncommon and is often considered normal. Some foods or medications can cause excessively smelly farts. There are, however, some instances where smelly farts can be an indicator of an underlying infection, digestive issues, or a disorder.

6 smelly flatulence causes

There are a number of reasons why your farts smell bad. In most cases, foul-smelling flatulence is associated with the foods you eat and an unbalanced diet. However, there can be more serious causes of rotten-smelling gas.

1. High-fiber foods

Many high-fiber foods can make you pass more gas. It takes longer for these foods to break down in your digestive system, so they ferment over time.

High-fiber foods also sometimes smell, which means your farts may smell too. This is especially true with strong-smelling vegetables such as:

Your gas may smell like rotten eggs because of the sulfur in fiber-rich foods. Sulfur is a natural compound that smells like spoiled eggs. Many vegetables are sulfur-based.

If this is causing your flatulence, a simple change in diet will be sufficient treatment.

2. Food intolerance

If you have a sensitivity or reaction to certain foods, your gas could have a foul odor. For example, people with lactose intolerance can’t break down the carbohydrate lactose. As a result, it is fermented by bacteria in your gut.

Gluten intolerance, or in its more severe form as Celiac disease, can also cause smelly farts. Celiac disease is an autoimmune disease where there is an immune response to the protein gluten. This leads to inflammation and injury in the intestine, leading to malabsorption. Flatulence can be a result of this.

Other than bad-smelling flatulence, Celiac disease can cause other symptoms:

Talk to your doctor to get tests and determine if you have any food allergies or sensitivities that may be making your farts smell.

3. Medication

Although uncommon, certain medications can cause smelly flatulence. Antibiotics kill off harmful pathogens in the body. They also destroy some of the good bacteria in your stomach, which aids digestion. Without this good bacteria, your gas may smell. You could also experience bloating and constipation.

Treatment for this cause involves changing medication, which you should not do without talking to your doctor first.

4. Constipation

Constipation indicates that you have a buildup of stool, or poop, in your colon. If you can’t poop regularly, it can cause bacteria and odor to develop. The end result is foul-smelling and sometimes painful gas.

Taking over-the-counter laxatives can be a simple home remedy for constipation.

Shop for laxatives

5. Bacteria buildup and digestive tract infections

When your body digests food, it extracts nutrients and sends them to the bloodstream. The waste products are sent to the colon. Disrupting the digestion process can cause an overgrowth of bacteria.

Some bacteria can cause infection in the intestines and digestive tract. This may cause a higher volume of gas than normal and a strong-smelling odor. People with digestive tract infections also often have abdominal pain and diarrhea.

Visit your doctor to determine if you have a bacterial infection. If you do, they will prescribe antibiotics to clear the infection and get you well.

6. Colon cancer

A more rare cause of smelly farts is colon cancer. When polyps or tumors form in the digestive tract, it can cause a partial bowel obstruction, which results in gas buildup and bloating.

If you begin to experience abnormal smelling gas and discomfort, and a change in diet or medication doesn’t affect your symptoms, call your doctor for full evaluation. They can determine whether a colonoscopy is warranted. Treatment for colon cancer varies based on the stage of cancer. It can include surgery to remove tumors and chemotherapy to kill cancer cells.

When to see a doctor

In most cases, having foul or odorless flatulence is no cause for alarm. However, if your gas is accompanied by irregular symptoms, you should visit a doctor immediately. Some adverse symptoms you may experience alongside smelly gas include:


Flatulence is natural and necessary to dispose of waste and gas in the body. There are some things you can do to get rid of smelly farts:

Period Farts

You talk period cramps and how you’re PMS-ing with friends. Chances are you’ve even bonded with a random stranger in a public restroom over the woes of forgetting to stash a menstrual product in your bag before heading out.

It’s easy to get real about periods, but it doesn’t get any more real than period farts. Yes, period farts. We know they’re a thing. You do, too. It’s time we talked about them.

Being especially gassy on your period is common, and so is that smell. That smell that causes you to blush at the realization that something so dank could possibly come out of your body.

Why it happens

Gas before your period as well as during is usually caused by fluctuations in hormones, particularly estrogen and progesterone.

Rising hormone levels in the days leading up to your period can do a number on your stomach and small intestine. These higher levels of estrogen cause gas, constipation, and trapped air and gas in your intestinal tract.

Right before your period starts, the cells in the lining of your uterus produce prostaglandins. These are fatty acids that function much like hormones.

Prostaglandins help your uterus contract to shed its lining every month. If your body produces too many, the excess prostaglandins enter your bloodstream and cause other smooth muscles in your body to contract — including those in your bowels.

This can lead to flatulence and changes in your bowel habits, which is fancy talk for period farts and the dreaded period poops.

It may be a symptom of something else, too

Gas and other gastrointestinal (GI) issues during certain stages of your menstrual cycle are pretty common.

But in some cases, they may be a sign of an underlying condition.

Irritable bowel syndrome (IBS)

IBS is a common condition of the large intestine that causes:

  • cramping
  • bloating
  • gas
  • abdominal pain

Several studies have found that IBS symptoms, including gas, are worse during your period. People with IBS also tend to have more intense period-related symptoms, like severe cramps and heavy periods.


Endometriosis causes the tissue that lines the uterus to grow outside the uterus, sometimes even outside the pelvis. GI symptoms are common in people with endometriosis.

Like IBS symptoms, endometriosis symptoms also tend to worsen during your period. These symptoms include:

  • gas
  • bloating
  • constipation

Painful periodspain during sex, and heavy periods are also common symptoms.

Why they smell so bad

The smell. Oh, the smell.

There are a few reasons why period farts smell have such a… unique scent. The main reason being that your gut bacteria change during your period, which can make flatulence extra fragrant.

The food you eat also contributes to the smell. But it’s not all your fault that you want to — and maybe do — eat all the junk when on your period.

Period cravings are very real. There’s evidence that high progesterone levels related to your period trigger compulsive eating and dissatisfaction with your body. Together, these can make it hard to muster the energy to care about what you’re eating.

Reaching for dairy, starchy carbs, and sweets change the smell of your farts for the worse and can cause constipation.

Speaking of constipation, the buildup of poop can cause bacteria and odor to develop, too, making for some even smellier toots.

What you can do

Farting is a biological process that we can’t really get away from. Even smelly farts are pretty normal. This doesn’t mean you’re destined to clear a room for three to eight days every month until menopause, though.


Here are a few ways to put a kibosh on period farts, or at least make them less smelly:

  • Drink plenty of water to help move waste through your body more efficiently.
  • Exercise to help you stay regular and avoid constipation.
  • Eat smaller portions at a slower pace to improve digestion and limit gas production.
  • Take a stool softener or laxative if you tend to get constipated during your period.
  • Try to resist the urge to binge-eat more often than not when you’re in the throes of PMS and your period.
  • Stay away from carbonated beverages. They can make you gassier.
  • Avoid foods that make gas smell worse, like cabbage and Brussels sprouts.
  • Take an over-the-counter (OTC) anti-inflammatory, such as ibuprofen (Advil) to reduce the production of fart- and poop-inducing prostaglandins.
  • Talk to your doctor about birth control pills. They may reduce or eliminate uncomfortable period symptoms.
Bottom line:

Farting is totally natural. We promise you’re not the only one experiencing some seriously funky farts during your period.

A few tweaks to your diet and lifestyle that are good for your health anyway may be all you need to put an end to period farts.

Speak to your healthcare provider about medical options, like birth control pills, if you’re experiencing other symptoms that may indicate an underlying condition.

Why do some farts feel warmer than others?

The average person farts, or expels gas from their rectum, 14 to 23 times per day. Many farts pass silently while you sleep. Others may come during the day, and those waves of gas can range from quiet but stinky to loud and odorless.

Occasionally, you may experience the sensation of “hot farts,” or feeling that the air passed during a fart is warmer than normal. The truth is the temperature of your toots is typically the same, but a few factors can make them feel warmer than normal.

Read on to find out what can cause that sensation and what you can do to keep gas passing tamed.

What causes burning farts?

On average, the temperature of the gas passed from your rectum is the same each time you break wind. Your farts may feel warmer in some instances. These causes may be to blame:

Low gas levels

It’s not bad to have fewer than normal farts. Each person’s gassiness level is unique and often based on the foods you eat and your lifestyle habits.

However, having less gas to pass may make toots seem hotter. That’s because when gas is expelled with a bit of force — that is, you have more to pass — it clears your rectum quickly. You don’t typically feel the air warm up around your anus.

If you have less gas, however, the gas may move slower with less force. In that case, the air may linger right around your bum, heating up the skin slightly.


The temperature of your gas doesn’t increase when you have diarrhea, but the skin lining your anus and rectum may become sensitive as a result of the increased bowel movements. That can make everything more irritated and painful, including your farts.

Spicy food

What’s hot going into your body is likely to be hot coming out. Spicy foods often contain natural substances, such as capsaicin, which impart a fiery flame to your tongue — and they do much the same to your anus during a bowel movement.

The food itself won’t make the gas you’re passing hotter, but it may make the sensitive skin lining your anus more irritated. That can make farts seem warmer than normal.

Tight pants

If you have on tight underwear or tight pants, the gas you expel from your rectum will likely hover just a bit longer around your bum before it’s dispersed through the fabric.

Hot farts and constipation

Constipation and hot farts can go hand in hand. When your gastrointestinal (GI) system is backed up and you haven’t been able to have a bowel movement for a few hours or days, your bowels have less space for gas. That means you won’t exert as much force when you do fart, which can make the toots seems hotter than normal.

Constipation can be caused by several factors, including:

  • eating a diet low in fiber
  • drinking too little water
  • getting too little physical activity

How to get rid of burning farts

One fart isn’t typically “hotter” than another, but you may feel more heat than usual depending on what’s happening with your GI system at the time. These treatments can help prevent hot farts and might ease any stomach troubles you’re experiencing, too.

Eat more fiber

Fiber is the secret ingredient for better GI health. When you eat plenty of fiber from fruits, vegetables, beans, and whole grains, you’ll lower your risk for constipation and increase your chances for regular bowel movements.

In other words, fiber keeps poop — and gas — moving right on through and out your rectum.

It’s important to note, however, that some fiber-rich foods, like broccoli, asparagus, cabbage, and Brussels sprouts, can actually increase the amount of gas you expel. They won’t increase the temperature of your farts, but you can anticipate passing a little more wind if you add these foods to your plate.

Take probiotics

When the bacteria in some probiotics are snacking on certain nutrients in your stomach and intestines, like fiber, they release microscopic amounts of hydrogen gas.

Some other probiotics, however, can actually break down that gas, which will reduce the amount of flatulence you have to pass. Fermented foods like yogurt, pickles, and kombucha are rich sources of these good bacteria.

Add herbs to your diet

Herbs like ginger, peppermint, and cinnamon have natural enzymes and chemicals that help your GI system move food faster. Some of these plants, such as peppermint, also have a calming effect on the intestines. That can help ease symptoms of diarrhea and reduce irritation in the sensitive skin.

Cut carbs

Your stomach can process a great deal of the food you eat, but there are some foods — ones with insoluble fiber, for example — that are just too difficult to break down. As the food sits in your stomach and the bacteria try to eat it, gases build up in your GI tract. That could increase the amount of gas you have.

You don’t want to cut all carbs — many healthy foods like fruits and vegetables are rich in carbohydrates. You should be selective about balancing some easy-to-process carbs with some that have more insoluble fiber. Beans, cabbage, cauliflower, and onions are all serious toot makers.

Drink more water

Air bubbles in carbonated beverages introduce more gas to your GI system. You may burp or belch more often and you may fart a few times. Still drinks, like water, tea, and wine are smarter for cutting the gas in your stomach. Also, staying hydrated helps prevent constipation.

Avoid spicy food

Scale back your spicy food intake if you experience fiery farts and bowel movements. Some of the chemicals in those hot foods can make sensitive rectum skin irritated.

Are burning farts good or bad?

Hot farts aren’t dangerous. In fact, they’re rarely a sign of anything you should be worried about. If you’re experiencing the high-temp gas passes with other symptoms like constipation or diarrhea, take steps to eat a properly balanced diet.

Diets that are filled with lean proteins, healthy carbs, fruits, and vegetables have a good balance of all the nutrients your GI system needs to keep things running smoothly and reduce the number of heated toots. Plus, a poor diet could lead to issues like vitamin deficiencies, an unhealthy microbiome, and much more.

When to see a doctor

Hot farts are rarely a sign of anything serious. But combined with some other issues, they may signal a bit of GI trouble or certain digestive disorders, like irritable bowel syndrome or even a bacterial infection.

If you start to experience other symptoms, like pain, nausea, vomiting, or diarrhea, consider talking with a doctor.

Bottom line:

Simple adjustments to what you eat may be all that’s necessary to reduce gas buildup and lower your risk for hot farts. However, warmer than usual toots are rarely a sign of any serious issues. If you take steps to make your whole GI tract healthier, you can expect the scorching rumbles from your rectum to cease, too.

Wet Farts

Whether you call it gas, flatulence, or farts, passing gas is a normal part of a person’s daily bodily functioning. Typically, farts are caused by excess air that is swallowed. This can be from chewing gum, smoking, or taking in excess air while eating.

It can also be caused by eating foods like beans and broccoli. They can release extra gases that cause too much air to build up in the intestines.

Sometimes you may experience a fart that isn’t just air escaping. This is the case for a “wet” fart. The sound may have a bubbling or liquid quality to it or be accompanied by liquid stool. Wet farts can indicate an underlying medical condition.

What causes them?

Typically, the anus releases extra gas from the rectum without any stool releasing. However, when a person makes a wet fart, there is some kind of fluid or mucus present in the rectum that is either released with the gas or makes additional noise when the gas is passed.

There are several reasons why this could happen.


Sometimes when a person is sick from a bacteria or virus affecting their stomach, food may pass through the digestive system very quickly and come out as watery stool (diarrhea). When a person passes gas, the watery stool can cause a wet fart.

Foods eaten

If a person eats a food that irritates their digestive tract or that can’t be absorbed by it, they may be more likely to experience a wet fart.

Examples include eating lactose-containing foods when they’re lactose intolerant. Drinking too much prune juice can also stimulate the bowels excessively.

Incomplete evacuation

If you’ve pooped recently and have a wet fart shortly after, this could indicate that you hadn’t fully emptied your bowels.

Medical conditions

Sometimes a person may have a disorder that causes bowel irritation and chronic diarrhea. Examples include inflammatory bowel diseaseCrohn’s disease, and ulcerative colitis.

Medication side effects

Taking a new medication can be irritating to the digestive tract and lead to diarrhea and wet farts. However, you shouldn’t stop taking a medication without your doctor’s okay unless it causes a severe allergic (anaphylactic) reaction.


Severe stress can cause abdominal cramping, and that, in turn, can make digested food pass more quickly through the digestive tract.

Why do children get them?

Babies and children can also have problems with wet farts.

As a parent or caretaker, you may notice the child’s diaper or underwear has stains on it even if a formed stool isn’t present. This can be especially common for babies because their stools don’t start becoming more solid until their diet changes to solid foods. As a result, they’re more likely to have wet farts.

While this isn’t usually harmful to your baby, you should check their diaper after each fart to ensure the stool won’t irritate baby’s bottom.

For an older child, wet farts can be less common and so are more likely to indicate one of the conditions listed above. This can include possible infection, problems digesting certain foods, or difficulty with a new medication.

How can you prevent them?

Preventing wet farts often depends on the underlying cause. If you’re having diarrhea most days of the week or frequent stomach upset, you should see your doctor.

However, there are some ways to maintain bowel regularity and reduce the likelihood that stool will be liquid, including the following.

Increase fiber intake

Slowly introducing more fiber into your diet can help to solidify stool. Examples of fiber-containing foods include:

  • whole grains
  • beans
  • raspberries
  • chickpeas
  • pears
  • apples
  • broccoli

Increasing your water intake while you boost fiber intake can help promote better digestion. Ideally, you will take in 20 to 30 grams of fiber a day.

Avoid foods known to cause stomach irritation

Lactose- and gluten-containing foods are two examples of foods known to cause stomach irritation. However, there are many more foods, drinks, and spices that can lead to stomach upset and that might contribute to wet farts. Keep a food diary to figure out what foods cause you digestive issues.

Talk to your doctor about digestive enzymes

Sometimes you may be able to take digestive enzymes to promote the digestion of foods known to cause stomach problems, such as lactose.

Make sure you completely empty your bowels

Sitting on your toilet an extra two to five minutes could ensure you’ve completely gone to the bathroom, making a wet fart due to retained stool less likely.

Just as there are beneficial ways to prevent wet farts, there are potentially harmful ones. For example, don’t cut back on drinking water to try to reduce the wet or watery nature of the flatulence. This isn’t an effective approach and can also leave you dehydrated.

Bottom line:

Occasional wet farts are to be expected. They usually indicate gastrointestinal upset. But if wet farts continue to occur on a chronic basis, you should talk to your doctor about potential treatments.
