Leaky Gut

Updated: Jul 19, 2021

Leaky Gut

Have you heard of a condition called “leaky gut?” (It could be the cause of most chronic health problems!)

10 signs that you might have a leaky gut:

  • Chronic diarrhea/constipation/bloating

  • Headache/brain fog/ poor memory

  • Poor immune system

  • Excessive fatigue

  • Skin rashes issues like acne, eczema, or rosacea

  • Craving for carbs or sugar

  • Depression/anxiety/ADD/ADHD

  • Arthritis/joint pain

  • Autoimmune conditions like lupus, inflammatory bowel disease, rheumatoid arthritis

What is leaky gut?

As the father of modern medicine, Hippocrates once said, “All diseases begin in the gut.”

The phenomenon of the leaky gut also referred to as increased intestinal permeability, has gained a lot of attention recently. A leaky gut is a digestive condition that affects the lining of the intestine, whereby there is a breach of the intestinal walls allowing bacteria and other toxins to enter into the bloodstream. The human digestive tract is where food is broken down and nutrients are absorbed.

The digestive system also plays an important role in protecting your body from harmful substances. The walls of the intestines act as barriers, controlling what enters the bloodstream to be transported to your organs. Small gaps in the intestinal wall called tight junctions allow water and nutrients to pass through while blocking the entrance of harmful substances. Intestinal permeability refers to how easily substances pass through the intestinal wall.

When the tight junctions of intestinal walls become loose, the gut becomes more permeable, which may allow bacteria and toxins to pass from the gut into the bloodstream. This phenomenon is commonly referred to as “leaky gut.”

Do you know that more than 70% of your immune system resides in the Peyer's patches/ GALT surrounding your intestinal wall? When there is a breach in the gut integrity, and bacteria and toxins enter the bloodstream, the body reacts by mounting an inflammatory cytokine response into the bloodstream as it realizes something is out of place. It can be a portal to long-term health complications and causes widespread inflammation in the body.

Ideally, our body selectively absorbs macro/micronutrients (the good stuff) through the intestinal wall and keeps all the bacteria/toxins/waste in that digestive tract to be excreted. Think of this as your sewage system (digestive tract) backing up and leaking into your water supply (bloodstream). Over time, the plumbing builds up and has a cumulative effect, wrestling a larger immune response and more widespread chronic inflammation.

This can result in many chronic health conditions such as new food intolerance/sensitivities, autoimmune diseases, digestive issues, malabsorption, brain fog, fatigue, mental disorders, and other inflammatory conditions like eczema, diabetes, irritable bowel syndrome, etc.

What causes a leaky gut?

  • Antibiotics

  • Excessive sugar/artificial sweeteners intake

  • Excessive alcohol consumption

  • Non-steroidal anti-inflammatory drugs (NSAIDs)

  • Herbicides/Pesticides in food

  • Chronic stress

  • Nutritional deficiency

  • Food allergens like gluten, dairy

  • Gut dysbiosis

  • Gut infections

  • Intestinal inflammation

How to heal a leaky gut?


  1. Remove - Food which you are sensitive/intolerant/allergic to (Do a Food Intolerance Testing to be sure), Infections, alcohol, refined sugar, antibiotics/NSAIDs, etc

  2. Replace - Digestive factors, hydrochloric acid, enzymes, bile salts, etc

  3. Reinoculate - Probiotics, Prebiotics, Synbiotics

  4. Repair - Nutrients for gut repair and healing: glutamine, vitamin A/D/E/C, Omega 3, Zinc, Curcumin, phosphatidylcholine, polysaccharides, etc

  5. Rebalance - Restorative processes like meditation, relaxation, breathing exercise, etc
