What causes hot farts and how to prevent them

Hot farts may mean that a person has eaten certain kinds of food that their body does not agree with, or has other digestive problems.

Based on factors that include food choices and how they eat, it is common for individuals to fart many times during the day. An individual may find, however, that some farts feel warmer or hotter than others.

Treating hot farts may not be appropriate in most situations, as this symptom normally passes after a bowel movement. Some over-the-counter ( OTC) drugs can, however, help to remedy continuous farting. An individual may need to see a physician in exceptional cases.

Over the counter drugs

The causes of hot farts differ from individual to individual.

In producing gas, diet plays a major role. As one study in Gut states, however, individuals can experience varying degrees of flatulence, even on the same diet. Every digestive system responds to different foods and habits differently.

Hot farts can also be accompanied by smells, and they differ depending on what foods a person consumes and how their body reacts.

Some potential causes of hot farts are given below.

Spicy food

In certain individuals, spicy foods may directly activate hot farts, as they contain compounds that can cause allergy problems. If a meal is spicy when it is eaten by a person, when they pass it on later, it may feel “spicy.”

This may also apply to the gas from the food. The rectum and anus can be more susceptible to spicy compounds in hot foods, which may make a person feel the fart more or make the fart appear hotter.

The symptom appears to be relieved by clearing the spicy food with a bowel movement.


Diarrhea is a symptom of a digestive system that is upset, and there are several causes.

Diarrhea itself, including the rectum and anus, appears to render the intestines sensitive. This could make it more likely for a person to feel a fart as it passes, which could give the appearance of a hot fart.

Other symptoms, such as a foul smell or a sour stomach, can accompany the fart.

Food intolerance

Several signs, including diarrhea, sore stomach, and hot farts, can be caused by eating food or drink that the body does not agree with. Examples include consuming milk or dairy products in lactose-intolerant people.

The gas a person releases can feel warm in these cases. It may also smell foul or sour and other symptoms, such as temporary diarrhea, can occur.

Anyone who suspects food intolerance may want to keep track of their diet and symptoms in a food journal. To identify and remove any unhealthy foods, work closely with a doctor or dietician.

Celiac disease

An immune deficiency that causes the body to respond to gluten is celiac disease. Gluten causes damage and inflammation in the small intestine in individuals with this disease, which may lead to many symptoms, such as hot or foul gas.

Celiac disease is a chronic illness, and the therapy requires completely removing gluten from the diet.

Low intestinal gas

Sometimes, because of low intestinal gas, a warm or hot fart can occur. From how much air they swallow while chewing to the kinds of foods and beverages they eat, many factors influence how gassy a person is.

As there is not much gas in the rectum to expel with force, a person with less intestinal gas may feel their farts are warmer. This may cause the warm gas to come out more slowly, which can make it feel warmer.

Tight clothing

Wearing thick, tight pants or underwear can also cause a fart to feel warmer, as after leaving the body, the gas lingers around the anus. There are usually no other symptoms in these cases, such as a disturbed stomach or a bad smell. It is simply a consequence of the warm air of the fart not leaving immediately, causing the individual to experience the warmth for longer.


Irregularity and constipation can trigger several digestive problems, including warmer farts. This can be due to the slowing down of the digestive system, which leaves less room for gas and making it harder to pass.

It can be in small quantities when the gas comes out, contributing to the warm sensation of a hot fart. Constipation relief can help to alleviate these warm farts.


Hot farts do not necessarily need counseling. The farts themselves are not dangerous and on their own are normally not a sign of serious illness. However, if there are unusual associated smells or other signs, a more extreme underlying disorder, such as food intolerance, may be suggested.

Hot fart symptoms are usually temporary and tend to pass after a bowel movement to remove the cause.

In cases of diarrhea, as the body recovers, it is necessary to remain hydrated. Drinking mineral water and electrolyte drinks can help restore body hydration and salt.

People may find that OTC medications, such as an upset stomach or indigestion, may relieve other accompanying problems. With these additional symptoms, ingredients such as bismuth subsalicylate (Pepto Bismol) and calcium carbonate (Tums or Rolaids) can help.

If physicians suspect an underlying condition, such as irritable bowel syndrome ( IBS), a low FODMAP diet might be prescribed, helping to avoid offending foods that cause symptoms.


Several changes in diet and lifestyle can help reduce hot farts. Some cases can also be prevented by taking steps toward optimum digestive health. Several tips include:

  • eating plenty of dietary fiber
  • eating fermented foods or taking probiotic supplements to promote the gut microbiome
  • eating foods and herbs that reduce flatulence
  • reducing foods that may cause extra gas, such as sugars or other carbohydrates
  • taking dietary enzymes when eating foods that are difficult to digest
  • avoiding foods that upset the digestive system, such as spicy foods
  • drinking more water
  • avoiding gassy drinks such as carbonated water or soda
  • wearing loose-fitting clothing
  • keeping a food journal to help identify and eliminate problematic foods

When to see a doctor

When the underlying cause goes away or after a bowel movement, most cases of hot farts are temporary and can clear up.

In rare cases, a more severe underlying digestive condition, such as IBS, can be an indication of continuous symptoms. Contact a doctor for a diagnosis if symptoms continue or do not get better within a few days.

In addition, while it is common to feel a warm or hot fart, pain accompanying farts can signify a different problem, such as hemorrhoids or anal fissures. Anyone experiencing pain as they pass gas should talk to their doctor.


Experiencing hot farts can trigger concerns , particularly if other symptoms accompany them, such as a foul smell or sour stomach. The farts themselves are, however, not dangerous.

In many cases , the cause is temporary, and symptoms rectify as soon as the body passes the offending foods.

People with these signs can have a chronic digestive disorder in rare instances. To diagnose and treat the underlying disorder, a person with recurring problems with hot farts should talk to a physician or dietician.
