It might seem embarrassing (and a little funny to some😂), but when your gas or p**p regularly smells like rotten eggs, your gut may be trying to tell you something.
That rotten-egg smell is often linked to sulphur-containing gases, particularly hydrogen sulphide, produced as gut bacteria break down certain foods.
And while what you eat can absolutely play a role, diet isn’t always the whole story.
If your bowels aren’t emptying regularly and your gut transit is slow, there’s more time for fermentation and bacterial activity which can mean more gas, bloating and some seriously offensive smells 💨
Persistent sulphur-smelling gas can sometimes be associated with things like:
🥚 Sulphur-rich foods
🐌 Slow gut transit / constipation
🦠 Changes in the gut microbiome
💨 Increased fermentation
⚠️ Certain gut infections or digestive conditions
So before you just blame last night’s eggs;
Pay attention to how often you’re actually emptying your bowels.
Your 💩 can tell you A LOT about what’s happening inside your digestive system.
And if the smell is persistent or comes with ongoing diarrhoea, pain, fever, blood in the stool or unexplained weight loss, it’s worth assessing.
Sometimes it’s just a fart. Sometimes it’s a clue. 👀
