How Many Times Should You Fart Per Day? Science Has the Answer

Scientists in Australia got serious about flatulence and created an app that tracked over 360,000 farts from 6,400 people. What they found was the most comprehensive data we have on normal fart frequency: the average person does it about 5 times per day, with the majority of people (79.3%) falling between 2 and 7 times daily. The research provides a useful baseline for what’s actually normal, because unlike a lot of bodily functions, most of us never talk about our gas patterns or compare notes with anyone else.

The study also revealed some interesting demographic patterns. People aged 26-45 are the gassiest age group, hitting just over 5 farts daily, while folks in the 14-25 range fart the least at 4.4 times per day. Men fart slightly more than women on average, and if you’ve noticed you’re gassier after dinner, you’re not imagining things—farts peak in the evening with smaller spikes around meals. The timing makes sense when you think about how your digestive system actually works throughout the day.

Here’s where this matters beyond just curiosity: excessive flatulence can signal that something’s off. If you’re way above the normal range, it could indicate lactose intolerance, gluten sensitivity, irritable bowel syndrome, or other digestive issues. Foods like beans, lentils, broccoli, and carbonated drinks increase gas production, as do habits like smoking and chewing gum. Knowing your own baseline helps you recognize when something’s genuinely wrong versus just being your normal body doing its thing. So where do you fall in the data—are you an average farter or are you above the curve?
