Smelly gases: causes and tips to alleviate them

Flatulence is a normal and healthy bodily function. Emission of gas can make some people uncomfortable, and smelly gas can cause embarrassment. Fortunately, there are strategies to help reduce or eliminate smelly gas.

Gas, farting, or flatulence refers to a buildup of gas in the digestive system that a person eliminates by passing wind through the anal passage. People fart several times a day, with some data suggesting that a person can fart anywhere from 5 to 15 times a day, while other data suggests it can be up to 25 times. It’s not uncommon for a fart to have an odor, and the causes can range from harmless to serious. Certain foods and medications can cause smelly gas, while other causes may indicate an underlying condition.

It’s not always easy to identify what’s behind smelly flatulence. However, implementing a few simple strategies can help prevent or reduce smelly flatulence. In addition, it may be advisable to consult a doctor. He may be able to identify possible causes and can provide recommendations to help people get rid of smelly gas. In this article, we’ll explore various home remedies, techniques, and strategies that can help eliminate smelly gas.

Farts refer to the evacuation of rectal gas. It is a normal biological process that forms as a result of the swallowing of air and the production of gases from the digestion of food. A person farts to get rid of excess gas that accumulates in the digestive tract. Gas coming out of the anus is known as flatus.

Intestinal gas is a normal by-product of digestion and can occur due to:

– Swallowing air: A person can swallow air when eating, drinking, chewing gum, smoking or if they have dental problems.

– Foods that are difficult to digest: Although gas production is normal with any food, it may be higher in foods that contain fiber, lactose or certain carbohydrates. When enzymes in the small intestine cannot fully digest food, bacteria in the colon break it down, which can cause excess gas.

– Intestinal bacteria: The intestine contains many bacteria that facilitate digestion by fermenting certain foods. This process produces excess gas. In addition, in some cases, the bacteria present in the intestines can multiply excessively and cause stomach disorders. This can cause symptoms such as diarrhea, flatulence, and stomach pain.

– The gaseous by-product can pass out of the body through the mouth as belching or through the anus as flatulence. Intestinal gas may or may not have an odor. Flatulence usually only smells bad if it contains strong-smelling gases, such as hydrogen sulfide.

– The presence of smelly gas after eating certain foods, especially those that are difficult to digest, is normal. However, in other cases, excessive or foul-smelling gas can indicate underlying health issues affecting the digestive system, such as irritable bowel syndrome (IBS).

home remedies for smelly gas

A person may be able to reduce smelly flatulence by making a few adjustments. Here are some strategies that can help prevent smelly gas:

Adding certain foods to the diet.

People may find it beneficial to include carminatives in their diet. This term refers to herbs or preparations that can prevent or reduce the formation of gas in the gastrointestinal tract. Here are some examples of carminatives:


Ginger has long been used as a herbal remedy for digestive issues. It helps fight constipation and flatulence by strengthening the contraction of the muscles of the digestive tract. This speeds up digestion, allowing gases to move faster and easier.

Peppermint is another herb that people can use for gastrointestinal (GI) conditions. A 2018 review notes that peppermint oil has a good safety profile and may help treat GI disorders. Other studies add that many herbs and essential oils contain carminative properties that may exhibit effective anti-flatulence characteristics.

Avoid certain types of food

Fiber-rich foods are difficult to digest. As a result, these slow-digesting foods take time to break down and undergo the process of fermentation, which produces odorous gases. Also, many of these foods contain sulfur, which is often the cause of smelly gas. Cruciferous vegetables such as broccoli, Brussels sprouts, and cauliflower can cause smelly farts.

Fermentable carbohydrates or FODMAPs can also cause digestive issues such as gas and stomach pain. These foods contain carbohydrates that are difficult to absorb in the intestine, leading to fermentation and gas buildup. FODMAPs include:

– lactose, which includes dairy products such as milk
– fructose, a sugar found in most fruits and vegetables
– fructans, present in many cereals such as wheat and barley
– galactans, present in legumes and beans
– polyols, present in sugar alcohols and sweeteners.

Likewise, food intolerances are a common cause of smelly flatulence. These are foods that people have difficulty digesting. Foods commonly associated with food intolerance are milk, gluten, sulphites, food colorings and preservatives, and caffeine.


Constipation can also cause smelly gas, as well as bloating and abdominal discomfort. This happens when stool builds up in the colon, but cannot come out, and bacteria continue to create gas. Dehydration, diet, and certain medications can lead to constipation. Taking extra fluids helps keep stools soft and easy to pass.

take probiotics

A person can increase the good bacteria in their gut by consuming probiotic-rich foods. This includes yogurts, kefir, kimchi, and sauerkraut. A 2017 study notes that probiotic intervention can reduce the number of pathogens in the gut that are associated with flatulence.

Medications and supplements

Activated charcoal can help reduce intestinal gas. According to a 2020 study, activated charcoal is a safe and cost-effective method for reducing gastrointestinal gas.
Also, people with food intolerances can take medication to help them digest troublesome foods. For example, people with lactose intolerance can take lactase tablets. These products contain the enzyme lactase, which is responsible for breaking down lactose.

Decrease habits that increase swallowing

Habits such as chewing gum, sucking hard candy, and drinking carbonated drinks can also increase the amount of air a person swallows. This causes it to expel more gas eventually.

Change in eating habits

Eating too quickly and talking while eating can also increase the amount of air a person swallows. Chewing and eating slowly can help reduce the absorption of air while eating, which reduces gas formation. Eating smaller portions can also help the digestive tract work better and produce less gas during digestion.

Causes of smelly gases

Several factors can cause smelly farts, ranging from mild to potentially serious. Common causes may include:

– food intolerances
– constipation
– the diet, especially foods rich in fiber and FODMAPs
– underlying digestive disorders, such as irritable bowel syndrome
– certain medications and antibiotics
– infections and bacteria of the digestive tract, such as small intestinal bacterial overgrowth (SIBO)
– colon cancer.

When to contact a doctor

Foul-smelling flatulence is usually not a cause for concern. For many, a few lifestyle and diet adjustments at home can help manage them. However, a person should see a doctor if the gas is persistent or accompanied by other symptoms, such as:

stomach pain
severe abdominal cramps
stomach pains
nausea and vomiting
bloody, oily, or foul-smelling stools
muscle pain or weakness


Smelly farts are usually normal and result from a person’s diet. A person may be able to manage and reduce foul-smelling flatulence by making changes to their diet and lifestyle. If smelly gases are frequent, it is advisable to contact your doctor. They may be able to suggest appropriate strategies or identify possible causes. If gas is due to an underlying condition, most people will get relief as soon as they treat the underlying cause.


Flatulence is a natural process of eliminating excess gas from the digestion of food. Everyone experiences smelly gas at one time or another. Certain types of food, certain health conditions, and certain habits can lead to smelly farts. Implementing strategies such as adding certain foods, avoiding problematic ones, and changing eating habits can help solve the problem of smelly gas in many cases.

Persistent, smelly farts can be a sign of an underlying problem, especially when other stomach issues are present. A person with severe and persistent flatulence may be advised to see their doctor for a proper diagnosis to understand the potential causes and suggestions for symptom relief.
