It's the gut bacterium everyone's talking about — linked to a strong gut lining, better metabolism, even how the immune system responds during cancer treatment. So why is it so often low? And how do you support it?

Your mouth has its own microbiome, and when it's out of balance the effects reach far beyond your teeth — to your heart, your gut, and your blood sugar. Here's what goes wrong, and what causes it.

Everyone says fermented foods are the healthiest things you can eat — so why do they leave you flushed, headachey and bloated? The answer is histamine, and there's a clear mechanism behind it.

A thick white coating, scalloped edges, a red tip — your tongue changes in ways that often track with your digestion. Here's how to read it as a clue (not a diagnosis) for your gut health.

You're losing the weight, but your gut feels awful — nausea, constipation, food that just sits there. That's not random. Here's exactly what GLP-1 medications do to your digestive tract, and how to support it.

"Leaky gut" gets dismissed by some and over-hyped by others. The truth sits in between: intestinal permeability is a real, well-studied mechanism. Here's what it actually is, what drives it, and how the gut lining is supported.

Bloating, gas, fatigue, brain fog — SIBO can look like a dozen other things, which is why it's so often missed. Here's what it is, how it's identified, what drives it, and why generic fixes so often fail.

If more fibre and more water haven't fixed your constipation — and sometimes made it worse — the issue may not be what you're eating, but how your gut is moving. Here's what's often really behind it.

Reach for an antacid, feel better for an hour, repeat forever. If that's your cycle, the standard story about reflux may have it backwards — and understanding why is the first step to actually breaking the loop.

You've tried every cream, serum and routine, and your skin still flares. What if the issue isn't on your skin at all? A growing body of research connects acne, eczema and rosacea to what's happening in your gut.

You eat, and instead of feeling energised you feel foggy, heavy, and ready for a nap. If meals leave your brain switched off, the explanation may lie in your gut — not your willpower.

You're doing "all the right things" and your gut still isn't better. Often it's not a lack of effort — it's a handful of well-intentioned mistakes that quietly keep symptoms going. Here are the five I see most.

You have a diagnosis and a label — but probably not a reason, or a real solution. IBS isn't a diagnosis so much as a description: your gut is irritable, and no one's told you why. Here's what's usually underneath it.

You eat something you've eaten a hundred times, and within an hour your stomach has doubled in size. If bloating after meals is your reality, the food itself is rarely the real problem. Here are the six root causes most often missed.

“I've never been well since…" — a holiday illness, a course of antibiotics, a stressful year. If you can name the moment your health changed, that memory isn't trivia. It's often the most important clue you have.

Two people live in the same damp flat. One is fine; the other is exhausted, foggy and reacting to everything. Mould affects people very differently — and why some can't seem to recover comes down to what's happening inside.

You start supporting your gut and briefly feel worse, not better. Is that the process "working," or a sign something's wrong? The honest answer is: it depends — and knowing the difference matters.

Bloating, gas, irregular digestion — and an "IBS" label that never quite explained it? A large share of IBS cases may actually be linked to SIBO. Here's how to tell them apart, and why the difference changes everything about getting lasting relief.
