Is it normal to fart once a month?
Unusual.Less common, but harmless
Farting only once a month is less common than passing gas more often, but you may not notice or remember every time. If you feel fine, it’s usually not a concern.
Most people pass gas more often than that because digestion naturally makes gas, but a lot of it can be quiet or go unnoticed. What you eat, how quickly you eat, and your digestion all affect how much you notice it.
If you genuinely rarely pass gas and feel comfortable otherwise, it’s probably just your normal. If you also have a swollen or painful belly, constipation, or trouble passing gas, get it checked.
