This page explains leaky gut clearly, including increased intestinal permeability, then helps you choose the right practitioner and next step.
Leaky gut is the common name for increased intestinal permeability.
Your intestinal lining acts as a barrier. It is designed to let digested nutrients pass through, while keeping larger particles, toxins and unwanted substances out of the bloodstream. When that barrier becomes irritated or disrupted, the tight junctions in the gut lining may not work as effectively. That is where the term leaky gut comes from.
Leaky gut is not usually the only issue present. In many cases, it sits alongside broader digestive problems such as microbiome imbalance, poor diet, chronic inflammation, food intolerances, stress overload, low stomach acid or a history of gut infections.
That is why effective gut repair usually starts with identifying the drivers, not just taking supplements at random.
Leaky gut symptoms often overlap with other digestive and inflammatory conditions. Some people mainly notice gut symptoms. Others notice wider health changes that seem unrelated at first.
Leaky gut symptoms can build slowly. Many patients do not describe one dramatic gut problem. Instead, they report a pattern of bloating, food reactivity, low energy, skin changes and feeling that their body is not coping with foods the way it used to.
| Digestive Symptoms | Systemic Symptoms |
|---|---|
| Bloating | Fatigue |
| Gas | Brain fog |
| Food sensitivities | Headaches |
| Abdominal discomfort | Joint aches |
| Diarrhoea or constipation | Skin flare-ups |
| Reflux or indigestion | Mood changes |
| Nausea or cramping | Difficulty concentrating |
| Feeling worse after certain foods | Low immune resilience |
Leaky gut can be driven by a mix of dietary, inflammatory, microbial and lifestyle factors. It rarely comes down to one single cause.
| Potential Cause | How It May Affect the Gut Barrier |
|---|---|
| Chronic stress | May disrupt digestion, immunity and microbiome balance |
| Ultra-processed foods | May increase irritation and reduce dietary diversity |
| Alcohol | May irritate the intestinal lining |
| Food intolerances | May trigger immune activation and ongoing gut irritation |
| Gut infections or dysbiosis | May affect the protective environment of the gut |
| Long-term medication use | May alter digestion or microbiome balance |
| Low nutrient intake or deficiencies | May reduce the body’s ability to repair the gut lining |
You do not need a formal diagnosis from a doctor or specialist to recognise a pattern in your gut health. Signs that it may be worth assessing your gut health include:
ongoing bloating or digestive discomfort
reactions to multiple foods
irregular bowel habits
fatigue or brain fog
skin flare-ups alongside gut symptoms
symptoms that return after short-term fixes
Testing for leaky gut can involve different approaches depending on the patient. Testing is not always the first step.
Some patients benefit from formal pathology or functional testing. Others first need a strong clinical review of symptoms, diet and gut history before deciding whether testing is worth it. Our Naturopaths may use the following depending on your health history and symptoms:
Digestive history
Food reactions
Microbiome or stool testing
Food intolerance testing
Nutrient patterns
Inflammatory patterns
Previous pathology and treatment history
Healing leaky gut usually requires a layered approach. The goal is not just to take one gut supplement. The goal is to reduce the factors aggravating the gut, improve digestive function, support the barrier itself and create conditions where the gut can repair properly.
The best leaky gut plan is usually the one that is specific to the person, not the one that throws the most supplements at the problem.
In practice, that often means:

Many people try to fix leaky gut by following generic advice or online protocols. This often leads to short-term improvement followed by relapse.
Common reasons people stay stuck include:
Removing foods without addressing underlying drivers
Using supplements without a clear plan
Not addressing stress or lifestyle factors
Misidentifying the main gut issue
Treating symptoms instead of patterns
The following foods and nutrients are often used by our Clinical Naturopaths when supporting patients with gut issues, particularly Leaky Gut Syndrome:
| Food or Nutrient | Why It Is Commonly Included in Gut Repair Plans |
|---|---|
| L-glutamine | Often used in gut repair protocols for intestinal lining support |
| Zinc | Important for tissue integrity and repair |
| Probiotics | Used to help restore microbial balance where appropriate |
| Collagen or bone broth | Often included as part of nourishing gut-focused meal plans |
| Omega-3 fats | Commonly used where inflammatory load is high |
| Fermented foods | May help support microbiome diversity in suitable patients |
| Fibre-rich plant foods | Can help support short-chain fatty acid production and gut function |
Diet plays a central role in gut repair, but it should not be overly restrictive unless there is a clear reason.
For most patients, the focus is on improving food quality, identifying trigger foods and building meals that support stable digestion rather than removing large groups of foods unnecessarily.
In particular, a leaky gut diet should focus on reducing irritation and increasing nourishment. For many patients, that means building meals around whole foods, improving protein intake, increasing fibre gradually where tolerated, reducing ultra-processed foods, reviewing alcohol intake and identifying possible trigger foods that are keeping the gut inflamed.
The best leaky gut diet is usually the one that helps the gut calm down while still giving the body enough nutrients to repair. This does not necessarily mean that the leaky gut diet should be restrictive.
Patients often want to know whether their gut repair plan is actually working. Signs your gut is healing may include:
Less bloating after meals
Fewer food reactions
More regular bowel movements
Better energy
Better mental clarity
Calmer skin
Less urgency or discomfort after eating
At Brisbane Livewell Clinic (Wavell Heights) and Brisbane Livewell Clinic (Cannon Hill), our Clinical Naturopaths and Clinical Nutritionists take a structured approach to digestive health. That may include reviewing:
Symptom patterns
Bowel habits
Food reactions
Stress and sleep
Diet quality
Previous treatment history
Potential microbiome imbalance
Testing already completed
Whether further testing is worth considering
Our Clinical Naturopaths and Clinical Nutritionists work with patients across Brisbane on gut health, intestinal permeability, food intolerances and broader digestive issues.
Many patients have already tried to manage their symptoms on their own before seeking help. They often come in after:
Many patients come in after trying to solve the issue on their own. They may have already cut out foods, tried probiotics or followed online gut protocols, but still feel stuck.
Naturopathic and Nutrition Practitioners help to separate noise from signal. Instead of guessing, the process of assessment and treating becomes more targeted. That often leads to clearer decisions about food, supplementation, testing and the next stage of treatment.
Leaky gut symptoms often include bloating, gas, food sensitivities, abdominal discomfort, fatigue, brain fog, skin flare-ups and irregular bowel habits.
Leaky gut is commonly linked with chronic stress, poor diet, alcohol, gut infections, food intolerances and microbiome imbalance.
Healing leaky gut involves identifying triggers, improving diet quality, supporting digestion and restoring gut balance.
Foods often include vegetables, quality proteins, healthy fats and whole foods that help support gut function.
Signs often include reduced bloating, more consistent digestion, fewer food reactions and improved energy.
If your symptoms keep returning, the next step is to understand what is driving them. Our Clinical Naturopaths and Clinical Nutritionists look at diet, gut bacteria, stress, inflammation and digestive function to identify the key contributors and map out a clear Wellness Plan.
