Is it normal to fart for 10 seconds?
Yep.Totally normal
Yes, a fart can last 10 seconds. Gas can come out in one long release, and there’s no set “normal” duration.
A long fart can happen when there’s a decent amount of gas ready to escape or it comes out slowly. Position and how relaxed you are can affect it, too. It may be startling, but by itself, a 10-second fart usually isn’t a sign that anything is wrong.
If it comes with ongoing pain, major bloating, or a sudden persistent change in your digestion, it’s worth checking in with a healthcare professional. Otherwise, it’s mostly a bathroom-story kind of event.
