Gut Health and Gut Repair

The Scientific and Holistic Perspective on Intestinal Integrity

 

Dr Kevser Köş | February 2026

 

Our gut is far more than a digestive organ. It functions as the central hub of our immune system and acts as a critical gateway between the internal and external world. Through this gateway, the body maintains balance and communication between all organs and systems.

This communication network is known as the gut–brain axis, gut–skin axis, and gut–metabolism axis. When gut health is compromised, its effects extend far beyond digestion—impacting immunity, hormones, skin health, mood, and even behaviour.

In recent years, you may have frequently encountered terms such as “increasedintestinal permeability” or “leaky gut syndrome.”

But what does this really mean, how is it linked to the immune system, and why does gut health influence so many aspects of our overall wellbeing?

 

What Is Intestinal Permeability?

The human gut is approximately nine metres long and is in constant contact with the external environment. Its inner surface is lined with a protective barrier that allows beneficial nutrients to pass into the bloodstream while preventing harmful substances from entering.

However, factors such as:

•poor nutrition

•chronic stress

•alcohol consumption

•intestinal infections

•antibiotic use

•inflammation

can weaken these tight junctions. When this happens, intestinal permeability increases. As a result, not only nutrients but also toxins, pathogens, and undigested food particles can leak into the bloodstream. This process initiates a cascade of physiological stress, increasing the toxic load on tissues and cells and impairing their normal function.

 

Intestinal Permeability and the Immune System

Approximately 70% of the body’s immune cells reside in the gut. When the intestinal barrier becomes compromised, the immune system detects these “leaks” and triggers an inflammatory response.

This process unfolds as follows:

1.Entry of foreign substances

Toxins and undigested food particles pass into the bloodstream.

2.Immune system activation

These substances are recognised as threats, prompting the release of inflammatory cytokines—essentially activating the body’s alarm system.

3.Chronic inflammation

If intestinal permeability persists, the immune system remains in a constant state of alert, leading to chronic inflammation.

Over time, this may contribute to autoimmune conditions (such as Hashimoto’s thyroiditis or rheumatoid arthritis), allergies, and even mood disorders such as depression.

 

Signs and Symptoms of Increased Intestinal Permeability

 

Leaky gut is not a disease itself, but it creates a foundation for many health problems. Common associated symptoms include:

Feeling constantly tired, struggling to get out of bed, or being unable to focus may be signsthat the gut is not functioning optimally and that toxins are affecting the nervous system.

Supporting and Restoring Gut Health

Improving intestinal permeability is possible through simple yet effective lifestyle changes:

 

1. Eat a Natural, Balanced Diet

Avoid processed foods, excessive sugar, and gluten.

Support gut microbiota with:

•fermented foods (yoghurt, kefir, sauerkraut)

•fibre-rich vegetables, fruits, and whole grains

Minimise packaged and ultra-processed products whenever possible.

 

2. Use properly Probiotics and Prebiotics

Probiotics increase beneficial bacteria, while prebiotics (such as garlic, onion, and banana) nourish them.

In cases where dietary intake is insufficient, stabilised probiotics delivered in oils offer an advanced solution.

Our Probiotic in Oils series supports gut balance at a deeper level—particularly Cocobiotic, which we strongly recommend for intestinal health.

 

3. Reduce Stress

Chronic stress negatively affects the gut barrier.

Practices such as yoga, meditation, and breathing exercises support both the nervous system and gut healing.

 

4. Avoid Harmful Substances

Alcohol, smoking, and unnecessary medication use can increase intestinal permeability. Reducing these factors is essential.

 

Gut Repair Through Aromatherapy: Nature’s Intelligence in Action

 

Aromatherapy—one of nature’s most refined gifts when guided by science—offers powerful support for gut repair and intestinal balance.

Aromatherapy is not merely about pleasant scents. When applied correctly, essential oils can:

 

1. Reducing Inflammation

Inflammation is a key driver of intestinal permeability.

•Turmeric essential oil supports digestion and intestinal motility.

In individuals with inflammatory bowel conditions, we often recommend adding turmeric essential oil to Cocobiotic, taken on an empty stomach before bedtime.

 

2. Balancing Gut Microbiota

Cocobiotic, a probiotic carried in coconut oil, helps restore the balance between beneficial and harmful bacteria, increases microbial diversity, and supports anti-inflammatory regulation of the gut.

 

3. Stress Regulation and the Gut–Brain Axis

Stress directly impacts gut permeability.

 

4. Supporting Digestion

Certain essential oils ease digestive discomfort:

 

A Holistic Reminder

The gut is the cornerstone of overall health. When aromatherapy is applied with the right oils, correct methods, and scientific understanding, it can support both physical healing and emotional balance.

A healthy gut is essential not only for bodily health but also for mental clarity and emotional wellbeing.

Invite nature’s healing intelligence into your life — create change through aromatherapy.
