So you've likely heard the term Leaky Gut used but what does it mean? Leaky Gut, also referred to as “Intestinal Permeability” is a condition in which the 'tight junctions' of the small intestine are affected. If you were to look at these junctions under a microscope, they would appear as small gaps in the intestinal wall. These gaps are important for how we absorb and assimilate food by allowing water and vital nutrients to pass through with ease to be absorbed by the body

while small enough to block the ability of foreign substances to pass through. So, naturally, when these tight junctions become damaged, foreign substances such as undigested food particles, waste products, and bacteria will “leak” through the walls of the intestine and into the bloodstream.

This degradation in the junctions will also lead to a noticeable decrease in the intestinal enzymes needed for proper digestion. When in the bloodstream the immune system builds IgG antibodies to these “foreign” molecules that do not belong and in turn, cause an autoimmune response that will treat some of the tasty morsels of food you love as enemies and will mark them as such for

potential perceived future “threats”. Consequently, being unable to digest common foods you would normally enjoy!

This immune response to these invaders can present in the body as any of these nine signs and

symptoms:

Chronic diarrhea, constipation,
gas, or bloating.
Food allergies or food
intolerances.
Poor immune system.
Headaches, brain fog, memory loss.
Excessive fatigue.
Skin rashes and problems such
as acne, eczema, or rosacea.
Cravings for sugar or carbs.
Joint Pain or Body Aches.
Mood imbalances such as
depression and anxiety.

What Can Cause Leaky Gut?

So, now that we are up to speed on the “what” of Leaky Gut, you may be wondering, “How did I get here?”

Here is a quick breakdown of some of the most common causes of Leaky Gut that can help

navigate the “WHY” behind gut permeability:

•Stress:

Chronic stress is a contributing factor to multiple gastrointestinal disorders, including leaky gut.

•Repeated ingestion of inflammatory foods:

Most common being gluten, dairy, alcohol, and sugar

•Gut Infections:

Small Intestinal Bacterial Overgrowth (SIBO), Candida overgrowth, and parasites due to

contaminated foods, water, or soil.

•Non-steroidal anti-inflammatory drugs (NSAIDs):

The long-term use of NSAIDs like ibuprofen can increase intestinal permeability and contribute to leaky gut

Supporting a Healthy Gut

Caring for the digestive system is an important part of overall well-being. A simple, structured approach can help the gut feel more balanced and supported. One helpful way to think about this process is through the 4 Stages of Gut Balance, which offer a clear path toward creating a more comfortable digestive environment.

Gentle herbs such as ginger, turmeric, and peppermint may offer additional comfort and help ease occasional bloating or digestive discomfort along the way.

The 4 Stages of Gut Balance

1. Remove

This stage focuses on stepping back from habits or foods that seem to create digestive discomfort. Paying attention to how your body responds to different meals can help you identify what to reduce or avoid for a period of time.

2. Replace

Here, the goal is to bring in supportive habits that encourage smoother digestion. This may include balanced meals, enough hydration, and mindful eating practices that help your body work more efficiently.

3. Reinoculate

This stage highlights the importance of foods that help support a nourishing gut environment. Examples include fiber-rich vegetables or fermented foods, depending on what feels comfortable for your body.

4. Repair

Finally, this stage focuses on choosing nutrient-dense foods and lifestyle habits that support the integrity of the gut lining and overall digestive comfort.

A Gradual and Personalized Process

Everyone’s digestive system is unique. Some people notice improvements quickly, while others may need more time and a gentler pace. What matters most is listening to your body and making changes that feel sustainable for you.

Working with a qualified professional can offer guidance and help tailor the approach to your individual needs.

Using a Food & Mood Journal is also a valuable tool. It helps you recognize patterns, identify foods that feel supportive, and understand which meals may contribute to discomfort.our body may be reacting to.
