Curious whether cannabis could help with SIBO symptoms — like bloating, pain, or gut inflammation?
You’re not alone. But there’s a lot of noise out there… so let’s look at what the science actually says.
I’m Bex an Accredited Practising Dietitian specialising in digestive health and evidence-based nutrition.
SIBO stands for Small Intestinal Bacterial Overgrowth — it’s when bacteria that normally live in the large intestine start to overgrow in the small intestine, where they don’t belong.
The result?
Bloating, gas, cramping, fatigue, and sometimes diarrhoea or constipation — often right after meals.
It can be caused by slowed motility, gut infections, surgery, or even stress.
Now here’s where cannabis comes in.
Compounds in cannabis — like CBD (cannabidiol) and THC (tetrahydrocannabinol) — interact with your endocannabinoid system, which plays a role in gut motility, inflammation, and pain regulation.
Early studies suggest that CBD may help reduce gut inflammation and visceral pain.
THC, in small doses, may improve appetite and reduce gut spasm.
That said — there is no direct evidence yet that cannabis treats the bacterial overgrowth itself.
It may help with symptom management, but not the root cause.
That’s why when I work with clients who have SIBO —
we start with proper testing, a personalised nutrition plan, and targeted strategies to restore balance.
And if you’re already using cannabis, or you’re curious about it, we’ll have a real conversation about what’s safe, legal, and backed by evidence.
No judgment. Just facts — and a plan that works for you.
If you’ve been dealing with bloating, gut pain, or brain fog after meals — and wondering if SIBO or cannabis could be part of the puzzle — reach out.
I offer 1:1 support, SIBO testing kits, and evidence-based care.
