“It is universally well known, that in digesting our common food, there is created or produced in the bowels of human creatures, a great quantity of wind.” — Benjamin Franklin

What is Flatulence?

Whether you call it farting, flatus, breaking wind or the technical term flatulence, what causes this bodily phenomenon? Why the variance of force and smell? Whether you are wondering what causes flatulence, how to treat flatulence or are concerned about a serious underlying health problem, you have come to the right place.

Flatulence Symptoms

Scientifically speaking, flatulence is the release of gas from the digestive system through the anus. You may be passing more gas than you realize — in fact, flatulence happens even as we sleep. It’s common to pass gas anywhere between 15 and 23 times a day. Surprised? One reason why we are unaware of the gas we emit is because most of it is unscented. Our large intestines produce mostly odorless hydrogen, carbon dioxide and methane gas, and we add to it by swallowing air (x).

Maybe you’ve been secretly wondering why some flatulence is quietly discreet, and why some farts are loud and explosive, or why some gas is accompanied by a burning sensation. In most cases, explosive flatulence is connected with large amounts of gas that have built up in the body. Hot or smelly flatulence is often related to what you ate recently (x).

What Causes Flatulence?

Flatulence happens for a variety of reasons. When we drink or swallow in big gulps, this can add excess air to our body. The food we eat contributes to flatulence, too. Certain foods are more likely to produce gas as they are broken down in the gut. Finally, certain digestive conditions and disorders can lead to flatulence as well (x).

Swallowed Air

The extra air we gulp in is sometimes released as a burp. But, if it doesn’t escape, the excess air can proceed down to the large intestine. Once there, it’s eventually released as flatulence. Normal amounts of air don’t usually cause us to pass gas, but sometimes we suck in more air than normal. Unusual amounts of swallowed air can happen through:

  • Drinking or eating too quickly in large gulps or mouthfuls
  • Drinking sodas and carbonated beverages
  • Chewing gum
  • Sucking on hard candies or cough drops
  • Smoking
  • Gaps in dentures

Aerophagia is the medical term for repetitive and excessive air swallowing. People with aerophagia gulp so much air that it causes unpleasant and painful symptoms like abdominal bloating, flatulence and belching. Aerophagia is often accompanied by extreme stress or other emotional issues (x).

The Foods We Eat

Certain foods can also lead to flatulence. The most likely culprits for gas production are cabbage, broccoli, beans, lentils, raisins, prunes and apples. Why are these foods notorious gas-producers? For one thing, they typically take longer to digest, causing odors and gas to collect in the gut. If not prepared properly, these foods can also be poorly absorbed. Then, bacteria enter the digestion process and release additional gas. Research shows that smelly flatulence is caused by sulfur compounds in the foods we eat (x).

Food ingredients that produce flatulence include:

  • Sorbitol. Sorbitol is typically added to sugar-free foods. It is in the group of sugar alcohols, and 50 percent of people cannot digest them or absorb them properly.
  • Fructose. This is found in high fructose corn syrup and naturally in fruits and vegetables. About one-third of people have fructose malabsorption, which causes them to struggle digesting these products. Even people that do not have fructose malabsorption can have difficulty digesting fructose-containing foods. This happens when a large amount of these foods are eaten in a short amount of time.
  • Lactose. People with lactose intolerance don’t have enough lactase to digest the sugar lactose, found in dairy products. And when lactose doesn’t digest properly, bacteria attack it in the gut and produce gas.
  • Raffinose. Cabbage, broccoli and brussels sprouts contain raffinose and so do beans (legumes). However, scientific studies show that if beans become a regular part of your diet, your body becomes used to them and flatulence subsides (x).

Digestive Disorders

Some health conditions can cause flatulence, including:

  • Constipation. Constipation in adults can have many causes. The most common are lack of fiber in the diet, lack of fluids, lack of exercise, change in diet, stress, medication side effects or pregnancy.
  • Indigestion. Indigestion is often related to diet and lifestyle, but it can also be a symptom of an underlying medical condition. Common causes of indigestion are overeating, eating too quickly, greasy or spicy foods, smoking, caffeine, alcohol, chocolate, stress and certain medications.
  • Irritable Bowel Syndrome. IBS is a relatively common condition and can cause a variety of symptoms such as bloating, constipation, diarrhea, stomach cramping and flatulence (x).
  • Crohn’s disease. Crohn’s disease is a chronic inflammatory disease of the colon and intestines, causing ulcers and other issues.
  • Celiac disease. People with celiac disease have an intolerance to gluten proteins found in wheat, barley and rye. Digestive disturbances are the result, one of which is flatulence (x).

Preventing Flatulence

Avoiding flatulence can happen by reducing swallowed air and decreasing intake of foods that typically cause gas. Adding fiber to the diet as well as a little more exercise and hydration can be helpful, too.

Reduce Swallowed Air

To reduce flatulence caused by air swallowing, consider these ideas:

  1. Drink slowly and avoid carbonated beverages.
  2. Eat smaller mouthfuls and chew slowly. Take meals in a relaxed state and avoid eating on the run.
  3. Reduce smoking and sucking on hard candies.
  4. Check the fit of your dentures.

Decrease Intake of Certain Foods

Reducing the amount of gas-producing foods you eat can diminish intestinal gas. Different foods can cause cause gas in some people but not in others. When you have a bout of excessive flatulence, take note of what foods you ate recently. Vegetables in the cabbage family, some fruits, dairy products and sugar alcohols are infamous gas producers. Soaking legumes before cooking and eating can reduce the likelihood of flatulence (x).

Add Fiber

Constipation is common for those who don’t get enough fiber in their diet. When your colon is obstructed, it’s more likely to accumulate gas-producing bacteria, leading to flatulence.

Hydrate & Exercise

Choose a walk after meals instead of a nap. Drinking plenty of water and getting regular exercise can help your digestive tract run optimally.

Flatulence Remedies and Supplements

When gas happens or indigestion arises, you need relief.  There are some ways to avoid gassy episodes or calm the tummy:

Add Enzymes

There are some products that help your body digest gas-producing foods. Some of these over-the-counter products contain lactase to help digest dairy products. Other products like Beano help digest the indigestible carbohydrates in beans and other vegetables.

Reduce Indigestion

Soothing supplements for indigestion include:

Support Your Stomach & Bowels

Supplements for stomach health include:

  • The B vitamins can help maintain a healthy gastrointestinal tract, especially Vitamin B3 (niacin)
  • Vitamin C aids in digestion
  • Vitamin D is connected with reduced risk for colon cancer and it is often lacking in individuals with digestive disorders
  • L-Glutamine promotes intestinal health
  • Probiotics promote friendly bacteria and can reduce flatulence (x)

The Bottom Line

The causes of flatulence include swallowing too much air, chronic digestive conditions and eating foods that produce gas in the intestines. Although everyone passes gas at times, involuntary gas-passing is generally undesirable. So, most people try to figure out how to minimize gassiness. This can be done by limiting the amount of air that is swallowed or reducing the intake of flatulizing foods.

When it comes to flatulence, prevention is better than remedy. But, there are supplements to promote a healthy digestive tract, boost levels of good bacteria and keep the stomach strong. Eating fiber, staying hydrated and getting exercise are helpful habits, too. Remember, in the fight against flatulence, we are all on the same team.
