What Causes Smelly Farts? Everything You Always Wanted To Know

Expert Series - What causes smelly farts

We’ve heard many questions and curiosities about our digestive processes. Today, we are exploring a topic that might raise a few eyebrows but is actually quite common: what causes smelly farts? We all experience flatulence from time to time, but have you ever wondered why some farts have a more pungent odour than others, or to put it bluntly, why does farting smell so rank? Let’s take a deep dive (with noses firmly held, thank you very much) into the fascinating world of intestinal gas and uncover what causes those not-so-pleasant smells.

Why do we fart in the first place?

Flatulence, commonly known as farting, is a natural process that occurs in the digestive system. It happens when excess gas builds up in the gastrointestinal tract and is released through the rectum.

When we eat or drink, we also swallow air, which contributes to the gas in our digestive system. Additionally, the breakdown of certain foods during digestion produces gases such as nitrogen, carbon dioxide, hydrogen, and methane. These gases are byproducts of the fermentation and bacterial activity that occur in the intestines.

It’s important to note that passing gas is a normal bodily function and helps relieve discomfort caused by the build-up of gas. However, excessive flatulence or quite strong smelling farts may be a sign of an underlying digestive issue. 

Why does farting smell? Aguulp

So, why does farting smell so bad sometimes? It all comes down to the composition of the gas and the specific foods we eat. Certain foods contain sulphur compounds, like those found in:

  • Cruciferous vegetables: broccoli, cabbage, and cauliflower
  • Onions
  • Garlic
  • High-protein foods like meat and eggs
  • Beverages such as wine and beer

When these foods are broken down by bacteria in our gut, they release smelly sulphur gases, resulting in farts that can clear a room. 

But it’s not just the food we eat; the balance of our gut microbiome also plays a role in what causes smelly farts

Our gut is home to trillions of bacteria that aid in digestion. When there’s an overgrowth of certain bacteria or an imbalance in the gut microbiome, it can lead to increased gas production and, consequently, more odoriferous farts.

Now, while we can’t completely eliminate the smell of our farts (after all, they’re a natural bodily function), we can take a few steps to minimise the odour.

Know what causes smelly farts & change your habits

Knowing what causes smelly farts can help you be more mindful of what to avoid eating and lifestyle habits you might want to change. For example: 

Watch your diet: Pay attention to the foods that tend to make your farts smell worse. Limiting your intake of sulphur-rich foods and processed foods can help reduce the intensity of the odour. Eating a varied diet to encourage a more diverse gut microbiome too can reduce the bad bacteria that can cause foul smelling gas.

Stay hydrated: Drinking an adequate amount of water aids in digestion and can prevent constipation, which can lead to more odorous gas.

Probiotics: Probiotics, often found in fermented foods or available as supplements, can promote a healthy gut microbiome. By improving the balance of bacteria in your gut, probiotics may help reduce gas production and improve overall digestive health.

Slow down while eating: Eating too quickly can cause you to swallow more air, leading to excess gas. Take your time and chew your food thoroughly to minimise the amount of air you swallow.

It’s important to remember, however, that occasional smelly farts are a normal part of life, and everyone experiences them. If you notice significant changes in your bowel habits, persistent abdominal discomfort, or other concerning symptoms, it’s always a good idea to consult with a healthcare professional to rule out any underlying medical conditions.
