Is it normal to never pass gas?
Unusual.Less common, but harmless
Most people pass gas, though it can happen so quietly or in such small amounts that you barely notice. If you’ve suddenly become unable to pass gas, especially with pain or swelling, get medical advice.
Passing gas is a normal part of digestion, but you may do it less often than you think—or simply not notice. What you eat and how your digestion works can affect how much gas you make.
If you mean you’ve never noticed it and you feel well, it’s probably not a problem. But if you’ve suddenly stopped passing gas, especially alongside a swollen or painful belly, vomiting, or trouble pooping, get medical advice promptly.
