Leaky gut and the repair phases

Somewhere along the way, your gut wall started letting things through that it was designed to keep out. This isn't a character flaw or a sign your body is broken. It's a boundary that got worn down — often quietly, over years — while you kept showing up, kept performing, kept overriding the signals asking you to slow down.

Let's understand what's actually happening, so you can stop reacting to symptoms and start supporting repair.

What "leaky gut" actually means

Your small intestine is lined with a single layer of cells, held together by structures called tight junctions. Think of them as the grout between tiles — snug enough to let nutrients pass into your bloodstream while keeping larger particles, toxins, and undigested food out.

When those junctions loosen, you get intestinal permeability — the more clinical term for "leaky gut." Larger molecules slip through into circulation, and your immune system, doing its job, treats them as intruders. The result is a low, steady hum of inflammation that can show up far from your gut.

This is why the symptoms can feel so scattered and confusing:

• Bloating, gas, and unpredictable digestion
• New or worsening food sensitivities
• Fatigue that sleep doesn't touch
• Brain fog and mood dips
• Skin flare-ups, joint aches, or heightened reactivity

If you've been told your labs are "fine" while your body clearly isn't, this is often the missing piece.

What wears the wall down

Rarely is there a single villain. Permeability usually builds from a combination:

• Chronic stress — sustained nervous system activation reduces blood flow to the gut and directly loosens those tight junctions
• Inflammatory foods and, for some, gluten, which can trigger a signalling molecule called zonulin that opens the junctions
• Gut imbalances — an overgrowth of the wrong microbes, or too few of the helpful ones
• Certain medications, including frequent NSAID use
• Alcohol and blood sugar swings

Notice how many of these trace back to a body that's been running in overdrive. Your gut lining is one of the first places burnout shows up physically — because digestion is a rest-and-digest function. When you live in fight-or-flight by default, repair simply isn't prioritised.

The repair phases

Healing the gut wall is sequential, not simultaneous. Trying to do everything at once is its own kind of grinding. Move gently through these phases instead.

Phase one — remove and calm. Reduce the ongoing irritants: the inflammatory foods, the constant stress load, the things quietly re-injuring the lining. This is nervous system work as much as nutrition. A regulated body is a body that can begin to repair.

Phase two — replace and support. Give digestion the tools it may be missing — adequate stomach acid, enzymes, and the raw materials for the lining to rebuild. This is where targeted gut-lining support comes in:

• L-glutamine — the primary fuel source for the cells lining your gut, helping them regenerate and hold tight junctions closed
• Zinc carnosine — well-researched for soothing and strengthening the gut lining
• Slippery elm — a gentle mucilaginous herb that forms a soothing, protective coat as it passes through

(Always check with your practitioner before adding supplements, especially if you're pregnant or on medication.)

Phase three — reinoculate and rebuild. Once the terrain is calmer, you nurture a healthier microbial community with fibre-rich foods and, if appropriate, probiotics — the long-term maintenance of a wall that holds.

A visualization: rebuilding my gut wall

This is where your design becomes practical. Repair happens fastest when your body feels safe, so pair the nutrition with a nervous-system cue.

Sit comfortably. Hand on your belly. Breathe slowly until your exhale lengthens.

Now picture the lining of your gut as a stone wall with a few loosened gaps. With each in-breath, imagine drawing in warm, golden material — nourishment, repair, calm. With each out-breath, see that material settling gently into the gaps, sealing them smooth. No force. Just steady, patient rebuilding, tile by tile.

Do this for two minutes. You're not imagining a miracle — you're giving your body the safety signal that lets its own repair machinery switch on.

A small practice for today

Before your next meal, pause and take five slow breaths, letting each exhale be longer than the inhale. That's it.

You're moving yourself, deliberately, out of the default state and into the mode where digestion — and healing — can actually happen. One meal at a time, you're teaching your body that it's safe enough to repair.

Your gut wall didn't break because you failed it. It's been waiting for the conditions to rebuild. Now you know how to offer them.
