Why do farts smell?

Although every human body is different, we all generally release gas between five and twenty-five times a day.

If that seems like a lot, take into account the amount of air you take in during the day. We swallow air when we talk, chew, and drink carbonated beverages. Since the air has to go somewhere, it comes out one end or the other: through a belch or a fart. And believe it or not 99% of the gas has no odors. But sometimes your farts are just too outlandish, something that makes you wonder why they smell so bad.

You might wrinkle your nose at the smell of your own fart. The smell is affected by what you ate along with the bacteria stored in your system. The food we eat is sometimes broken down and absorbed in the small intestine, but it can pass into the colon, where it is broken down by bacteria. These bacteria then produce certain gases, which can have a bad odor.

You may also notice a foul odor when you are constipated. When you're without a bowel movement, food stays for an extended period of time in your colon, where the bacteria have an extended period to create more byproducts, and therefore smellier farts.

The silent farts They're the worst, and they really smell bad because of the fermentation of bacteria in the colon. If you have stinky gas, it's probably something you ate, and nothing to worry about. Gas is a normal and healthy byproduct of digestion, after all. However, sometimes a bad odor can indicate a more serious health problem that requires a thorough examination by a GI doctor.

The loud "fart" noise is caused by a patient squeezing the anus, and the hydrogen sulfide gas vibrates the tense muscles of the spinal cord as if they were vocal cords. This retains much more gas in the colon than farting with a relaxed anus. Since more gas is expelled with relaxed muscles, the released silent fart tends to smell worse.

Causes of having smelly farts

One of the less favorable but most commonly reported odors released by the body is smelly, rotten eggs. These can take your breath away and you need to clear the room if you let one pass in front of the others.

High-fiber foods

When this stench occurs, it is likely due to having too much sulfur in tor diet. When we have sulfur-filled foods, our digestive system creates and emits hydrogen sulfide, mimicking that rotten egg smell.

Certain foods, including cruciferous vegetables like cauliflower, broccoli, kale, cabbage, Brussels sprouts, and other leafy greens, could be to blame. Other foods high in sulfur, such as eggs, red meat, onions, garlic, cheese, nuts, beer, and wine, can also trigger egg farts. These foods take longer to break down in your digestive system, so they ferment over time.

high protein foods

Protein supplements are often used by athletes, and are also a form of weight loss for people looking to stay full on fewer calories. Protein is also an essential nutrient needed to build muscle mass, which is useful for both considerations.

There is no evidence that a high-protein diet causes us to have a lot of gas, but it can smell very bad. There is some anecdotal evidence that protein powder supplements increase flatulence, but this effect is likely caused by non-protein components added to protein powders, such as lactose.

Although protein itself does not increase flatulence, protein supplements may contain other substances that cause gas. Whey or casein protein supplements may contain high amounts of lactose. A high intake of lactose can increase flatulence, even in people who usually consume dairy without any problem.

Some protein powders contain additives that cause flatulence. These include certain thickeners and sweeteners, such as sorbitol. Other plant-based protein sources can also contribute to flatulence, such as cereals and legumes.

Alimentary intolerance

Other times, the gases remind us of other familiar but undesirable aromas, such as cabbage, sewage or burning rubber. One reason for this is the lack of enzymes in tor intestine.

Dairy may be the culprit here, as it contains the protein lactose. The small intestine breaks down lactose with the enzyme lactase, turning it into glucose and beta-galactose. These simple sugars are then absorbed through the intestinal wall. If a person has low levels of the lactase enzyme, the lactose passes through and encounters bacteria. The bacteria then ferment the undigested lactose, producing methane gas, which has a foul odor.

intolerance to gluten it can also cause smelly farts. Celiac disease is an autoimmune disease in which there is an immune response to the gluten protein. This leads to inflammation and injury in the intestine, which leads to malabsorption. Flatulence can be the result of this.


Legumes are a rich source of protein, antioxidants, nutrients and minerals. But they get a bad rap for making us pass gas. Beans contain oligosaccharides from the raffinose family. Raffinose is a group of sugars that are, at least partially, responsible for bloating and gas after a meal rich in legumes. This is because the digestive tract lacks an important enzyme needed to break down and digest these sugars.

Whole grains, asparagus, and cruciferous vegetables also contain raffinose. Taking an enzyme-based digestive aid may help relieve symptoms.

other sugars

In addition to raffinose, other sugars, including sorbitol and fructose, can also cause unpleasant flatulence. Sorbitol can be found in fruit, sugar-free candies, and artificial sweeteners. Fructose is found in fruits, soft drinks, onions, wheat, artichokes, and pears.

Keeping a food diary can help determine if sorbitol or fructose is the cause of stinky gas.


Constipation indicates that we have an accumulation of feces or poop in the colon. If we don't manage to poop regularly, we can cause bacteria and odor to develop. The end result is a smelly and sometimes painful gas.

Taking over-the-counter laxatives can be a simple home remedy for constipation. Although mainly you have to resort to improving your diet and leading healthy lifestyle habits.


Although rare, certain medications can cause foul-smelling flatulence. Antibiotics kill harmful pathogens from the body. They also destroy some of the good bacteria in the stomach, which aids in digestion. Without these good bacteria, your gas can smell. You may even experience bloating and constipation.

People taking weight loss medications often experience gas with an oily discharge. It is also known that iron supplements They cause gas and bloating. Supplements that contain fiber can cause gas as a side effect, and the diabetes drug metformin can also cause gas.

Diabetes medicines called alpha-glucosidase inhibitors, which slow the absorption of carbohydrates, can also cause increased gas. Treatment for this cause involves changing your medication, but it's not something you can do without first talking to your doctor.

FODMAP-rich foods

FODMAPs, foods that contain short-chain carbohydrates, can also cause gas-smelling digestive problems. These are poorly absorbed in the small intestine, are osmotically active (meaning they increase intestinal water content), and are rapidly fermented by intestinal bacteria. In the case of sensitive people, this can cause more gas and a worse smell.

Unfortunately for sensitive stomachs, all kinds of foods contain FODMAPs, including certain fruits (like watermelon and mangoes) and vegetables (like broccoli and Brussels sprouts), high-fiber grains, onions, dairy products, etc. We will also find FODMAPs in sugar alcohols (such as sorbitol) and fructose in many processed foods.

Accumulation of bacteria in the digestive tract

When the body digests food, it extracts nutrients and sends them to the bloodstream. Waste products are sent to the colon, and disruption of the digestion process can lead to an overgrowth of bacteria.

Some bacteria can cause infections in the intestines and digestive tract. This can cause a higher than normal volume of gases and a strong odor. People with digestive tract infections also often have abdominal pain and diarrhea. If you think you have a bacterial infection, see your doctor. In the case of having it, antibiotics will be prescribed to eliminate the infection and cure it.


There are a few reasons why the smell of menstrual farts has a unique aroma. The main reason is that gut bacteria change during your period, which can cause flatulence to smell like eggs.

The food we eat also contributes to odor. But it's not our fault that we want to eat all the junk food when we're on our period. Period cravings are very real. There is evidence that period-related high progesterone levels trigger binge eating and body dissatisfaction. Together, these can make it hard to muster the energy to care about what we're eating.

Eating dairy, starchy carbohydrates, and sweets worsen the smell of farts and can cause constipation. Which, by the way, poop buildup can also cause bacteria and odor to thrive, making some pegos smell even more.


Pregnancy is a time when a change occurs in a woman's body, often making life uncomfortable. It can be a time for nausea, back pain, and heartburn. Sometimes unpleasant odors are also present. One of the most common odor problems is farts. Sometimes these pregnancy farts can smell so bad that you might want to hold your nose when you realize it's coming.

Hormonal changes during pregnancy can also make farts smell bad. For example, increased progesterone levels can slow down the digestive system and lead to increased gas production. The growing uterus during pregnancy puts pressure on the gastrointestinal tract, causing gas and flatulence. This also leads to a loss of smelly gases during the early stages of pregnancy.

Indigestion is also common in pregnancy and this can cause farts worse than ever. It is caused by decreased motility in the intestine, which leads to the accumulation of gases.

Irritable bowel syndrome

Irritable bowel syndrome, a condition in which dysfunction in the large intestine causes digestive problems like abdominal bloating and pain, and bouts of diarrhea and constipation, is another common culprit for smelly-egg farts.

Although usual gas alone is not enough to diagnose irritable bowel syndrome, changes in odor and gas production are common factors. Managing irritable bowel syndrome typically involves making healthy diet and lifestyle changes and managing stress.


A rarer cause of smelly farts is colon cancer. When polyps or tumors form in the digestive tract, they can cause partial intestinal obstruction, resulting in gas buildup and bloating.

If we begin to experience discomfort and gas with an unusual odor, and a change in diet or medication does not affect the symptoms, it is advisable to call a doctor for a complete evaluation. He will usually order a colonoscopy to determine this. Treatment for colon cancer varies depending on the stage of the cancer. It may include surgery to remove tumors and chemotherapy to kill cancer cells.

How to prevent smelly gases?

If you're getting overwhelmed by your smelly farts, consider seeing your primary care doctor, who can test your bowel movements and frequency. With this information, you may be referred to a digestive professional if a GI tract problem is suspected.

However, you can put an end to stinky flatulence by changing your diet. There are times when the underlying cause may be more serious than the body's reaction to certain foods or mild constipation. In these cases, gas interruption will happen through treatment of the underlying condition.

Improve your fiber for gases

This nutrient works wonders to stabilize our blood sugar levels, which causes us to eat less and leads to a feeling of fullness. In addition, it benefits our cholesterol levels and intestinal health in general.

If you decide to increase your fiber intake, you should do so with caution, as it could have the opposite effect if you introduce it too quickly.

Eating large amounts when we are not used to it can cause flatulence due to the by-products of the bacteria. So when increasing your daily fiber intake with food or supplements, it should be done gradually.

You can slowly increase the amount of fiber you're eating by a couple of grams, and be sure to increase your water intake while you're at it, which can help prevent constipation (and more gas).

Try a low FODMAP diet

Some foods produce more gas than others. Certain carbohydrates are common culprits, including those that contain fructose, lactose, insoluble fiber, and starch. These carbohydrates are fermented in the large intestine and have a history of causing digestive problems.

Many of those high sulfur foods fall into this category. If you have frequent, unpleasant gas, trying a low-FODMAP diet for a month can significantly lessen your symptoms. Additionally, people with irritable bowel syndrome often experiment with a low-FODMAP diet, which avoids fermentable sugars.

However, many of these gas-producing foods are an essential part of a healthy diet. So you may not need to completely eliminate these foods from your diet, but you can eat less.

Take probiotics

When the bacteria in some probiotics eat certain nutrients in the stomach and intestines, such as fiber, they release microscopic amounts of hydrogen gas.

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

reduce carbs

Your stomach can process much of the food you eat, but some foods (such as those with insoluble fiber) are just too hard to break down. As food sits in the stomach and bacteria try to eat it, gas builds up in the GI tract. That could increase the amount of gas we have.

It's not about cutting out all carbs: Many healthy foods, like fruits and vegetables, are high in carbs. You have to be selective in balancing some easy-to-process carbohydrates with some that have more insoluble fiber. Beans, cabbage, cauliflower, and onions are all serious egg-smelling fart makers.

take ginger

Ginger is one of the best natural remedies to relieve gas. It is commonly used in Chinese medicine as the main ingredient in herbal digestive solutions. Ginger speeds up digestion and can soothe the digestive tract. This allows gas to move more smoothly into the lower intestine, giving you relief from any gas problems.

By improving digestion, the amount of gases will be less and the smell will not be so noticeable. In addition, it will reduce smelly farts by having better digestions.

Other tips

Flatulence is natural and necessary to eliminate waste and gases from the body. There are a few things we can do to get rid of smelly farts:

  • Eat smaller portions at a slower pace to promote healthy digestion and reduce gas production.
  • Drink more water to help move waste through the body more efficiently.
  • Include probiotic foods like yogurt in your diet to help restore healthy bacteria in the body and improve digestion.
  • Avoid carbonated drinks that can cause gas, such as beer, sparkling wine, and sodas.
  • Try to avoid foods that contribute to egg odor.
  • To do physical exercise.

Is it bad to hold the farts?

When the body accumulates excess gas within the digestive system, there are only two places it can exit. The gas that causes farting (and also belching) normally builds up during digestion and also when you swallow air along with food while eating or drinking. Gas can cause bloating and discomfort, so farting is a healthy way to release gas from the body.

Farting is totally natural and everyone's body does it. Most people fart five to 23 times a day. However, some may feel embarrassed or uncomfortable if they fart more frequently, have uncomfortable or smelly farts, or have to fart in public. Some people try to hold in their farting until they feel safe enough to let it out or the gas escapes uncontrollably.

In the 1970s, experts discovered that the habit of holding farts could be associated with the development of diverticulitis. This is the inflammation or swelling of the bags that form along the digestive tract. Diverticulitis can be serious and can cause infection if left untreated.
