About this episode
Your gut symptoms might not be caused by gluten. Dr Will Bulsiewicz is a leading gastroenterologist and gut health expert specialising in the microbiome, digestion and the science of food. In this moment, Dr Will Bulsiewicz reveals why bloating, gas and constipation are often misunderstood, and why the real trigger behind your symptoms might not be gluten. Learn how your microbiome is quietly shaping your digestion, inflammation and long-term health. Listen to the full episode here!

Episode summary
Quick one on bloating and regularity—if I’m gassy or uncomfortable, does that automatically mean something’s wrong?
Everyone has the odd off day, but if you wake up hoping today isn’t another rough gut day, that’s a real issue and it’s fixable with a tailored plan drawn from the same core tools.
What about frequent farting—does that point to one problem or many?
Constipation tops the list, and it’s not just about how often you go; incomplete, hard-to-pass, unsatisfying trips count too, and gas often eases once you finally have a full bowel movement.
Stool is largely microbes, and when transit stalls those bugs have extra time to ferment food and pump out gas, so backups often mean bloat.
People blame dairy or gluten for gas—so is that constipation or something else?
Constipation is common, but gas can also come from off‑rhythm motility, a weakened microbiome that struggles with fiber, or diet triggers like lactose and the fructans found in wheat, barley, and rye; a steady daily rhythm helps.
I used to handle pasta fine, now it floors me for days, though gluten‑free feels better; some folks say they’re gluten‑intolerant—what’s going on, and would Italy be different?
Many go gluten‑free unnecessarily, and processing matters—pre‑harvest glyphosate used on some U.S. wheat isn’t labeled and may disturb gut microbes, while organic avoids it; plenty of people report tolerating wheat abroad.
I’ll try organic pasta.
Also notice if sourdough sits better, because fermenting dough lowers fructans and often improves tolerance.
So it might be fructans, not gluten, that trip me up?
A controlled trial in self‑reported gluten‑sensitive people found fructans triggered symptoms while gluten didn’t, and classics like garlic and onions can do it too, whereas grains like sorghum and quinoa are typically fine.
How long does it take to heal a stressed gut, roughly?
It depends on where you start; in severe cases like Crohn’s or ulcerative colitis we aim for deep remission, and those raw, ulcer‑like patches reflect an immune system that’s mistakenly targeting the microbiome, a mismatch shaped early in life.
What drives conditions like IBS or Crohn’s—lifestyle, genetics, something else; what’s the main culprit?
There’s a genetic base, but rates climb with industrialization, and one big modifiable risk is antibiotics, which can halve diversity, weaken the barrier, spark immune activation, and roughly double short‑term IBD risk in both kids and adults.
