Can cause leaky bowel hernias

Leaky Gut Syndrome / Permeable Gut: Symptoms & Treatment in Munich

If the protective barrier of the intestinal wall is not intact, which is known as leaky gut syndrome (syn .: leaky intestine, permeable intestine), undigested food components, bacteria, toxins and metabolic products enter the bloodstream through the damaged intestinal mucosa. They cause inflammation here, which can be associated with a wide variety of clinical pictures. Recently, many chronic diseases, including some autoimmune diseases such as inflammatory bowel disease (IBD), multiple sclerosis, type I diabetes, and Hashimoto's thyroiditis, have been linked to leaky bowel syndrome.

Definition: Leaky Gut Syndrome

"Leaky Gut" is an English term that translates as "leaky intestine" or "permeable intestine". In the healthy intestine, the cells of the intestinal wall form a dense cell network. The connection points of the individual cells are sealed by so-called tight junctions. If these tight junctions leak, the leaky gut syndrome develops.

Immune system gut

The intestinal wall that unfolded a Area of ​​300-500 square meters that is the entire size of a football field, and is by far our largest contact area with the outside world, has to fulfill a difficult double function: on the one hand, it has to be so permeable that nutrients and fluids can be absorbed from the inside of the intestine, but on the other hand it has to have a protective mechanism that hold back harmful substances and pathogens.

Various structures and cells ensure the protective function in the intestine. Just as there is a protective layer against environmental influences with the outer skin, there is also a mucous membrane inside us, which lines and protects the nine-meter-long digestive tract from the mouth to the anus. This mucous membrane is populated with an intestinal flora from a wide variety of bacterial strains.

For example, they settle in the large intestine 300-400 different types of bacteria that make up around 100 billion bacteria in total. That is around ten times as many microorganisms as there are cells in the human organism. Together they have the task of recognizing harmful bacteria and other unnatural substances and rendering them harmless and at the same time producing many different B vitamins, vitamin K and folic acid.

The intestinal flora is a dynamic bacterial ecosystem that begins to develop in the still sterile infant intestine after 24 hours through initial contact with the maternal vaginal and intestinal flora in naturally delivered children. The intestinal immune system, which is located in the submucosa, i.e. under the intestinal mucosa and acts as a largest immune organ in humans 80% of the active immune system forms.

The strength of the human immune system therefore depends crucially on an intact situation within the intestine. This makes it understandable that a large number of diseases outside the intestine can be causally linked to a leaky intestine. In this context, the importance of leaky gut syndrome and its role in chronic diseases and autoimmune diseases has been increasingly discussed for a few years now.

How is a permeable intestine created?

Leaky intestines from modern lifestyle

On the one hand, our modern lifestyle with a lot of stress, industrially modified foods and numerous environmental toxins often lead to an imbalance in this unstable ecosystem of intestinal bacteria. An increase in putrefaction and fermentation at the expense of acidification-forming bacterial colonization can be observed, which is known as dysbiosis. The resulting fermentation processes form fusel alcohols. As a solvent, these then have a damaging effect on the tight junctions between the mucous membrane cells of the intestine and thereby cause a leaky intestine.

Dysbiosis of the intestinal flora


  • Caesarean births
    It is now known that it is not the newborn baby who first receives intestinal bacteria from the mother's vaginal environment at birth, but that the immune system of the unborn child receives signals from the bacterial flora of the mother's intestine while in the womb. Those born by caesarean section are usually equipped with an inadequate intestinal flora and are therefore more susceptible to intestinal diseases, lung diseases, skin diseases, allergies, ADHD, obesity and autism (according to the children's health report of the Techniker Krankenkasse). A heightened one Parents can determine the risk of falling ill with a simple stool test and, if necessary, treat it at an early stage:

Darmcheck infants not breastfed
Microbiological analysis of the aerobic and anaerobic lead germs, of molds and yeasts (Candida albicans and Candida spp.), Α-1-antitrypsin, calprotectin, EPX, lysozyme and sIgA in the stool of non-breastfed infants

Colon check infants breastfed
Microbiological analysis of the aerobic and anaerobic lead germs, molds and yeasts (Candida albicans and Candida spp.), Α-1-antitrypsin, calprotectin and EPX in the stool of breastfed infants

Above all, an oversupply of sugar and carbohydrates, especially from wheat products, has a harmful effect. Grains are the seeds of grass. No plant voluntarily gives up its reproductive material, otherwise it would become extinct. This is why plants have formed so-called antinutrients in the course of evolution, which occur e.g. in the seeds of cereals and legumes. This makes sense from a biological point of view, because it offers protection against consumption by animals - and since the Neolithic revolution 12,000 years ago also by humans, who at that time began to go from hunters and gatherers to arable farmers.

Antinutrients include lectins, including gluten as a special lectin and wheat germ agglutinin. Wheat and other cereals containing gluten are not well tolerated by many people. Gliadin, a part of gluten, is responsible for the poor tolerance. The human organism can still handle a certain amount of these antinutrients. However, excessive consumption of the main sources of these anti-nutritional substances, especially wheat, should be avoided or defused by soaking, sprouting or fermenting legumes and grains.

Gluten, Lactose and Leaky Gut Syndrome

On the other hand, it is probably an allergic reaction of allergy type III. Antibodies are formed against gluten, lactose or other food antigens. Together, the antigens and antibodies form immune complexes that attach to the intestinal wall and damage this tissue through the inflammation that is a sign of the immune reaction.

The resulting increased permeability of the intestine can lead to bacteria and their toxins as well as undigested food components penetrating the intestinal wall into the blood. These substances activate the intestinal immune system and trigger an inflammatory reaction. Immune cells then release messenger substances that further increase the permeability of the tight junctions and continue the inflammation - a vicious circle is created.

Inflammation of the intestinal lining

Chronic inflammation of the intestinal mucosa is caused by

  1. Chronic inflammatory bowel disease (ulcerative colitis, Crohn's disease)
  2. Bacteria, viruses, fungi, parasites
  3. Toxins: nicotine, alcohol, heavy metals, environmental pollutants, etc.
  4. Celiac disease
  5. Lactose intolerance
  6. Food allergies

Leaky bowel and autoimmune diseases

Another problem can arise when the immune complexes of antigens and antibodies formed in the intestine get into the bloodstream and attach to a distant tissue, such as the thyroid gland.

As a result of the original immune reaction in the intestine, the inflammatory process would have shifted to a distant tissue, in this example the thyroid gland, resulting in a kind of collateral damage, which is then called Hashimoto's thyroiditis. So far, however, this is only one hypothesis that needs to be further investigated as one of the many possible causes of autoimmune reactions - and must by no means be neglected.

We now know a number of certain triggers that can lead to a leaky intestine and thus to weakness (susceptibility to infection), dysregulation (autoimmune disease) or overreaction (allergy) of the immune system.

Diseases that can result from leaky gut syndrome

Current scientific studies assume that the leaky gut syndrome plays a very important role in the development of diseases inside and outside the intestine. These include:

  • Autoimmune diseases, e.g. type I diabetes, celiac disease, Crohn's disease, ulcerative colitis, rheumatoid arthritis, multiple sclerosis, lupus erythematosus, Graves' disease and Hashimoto's thyroiditis
  • Allergies
  • Irritable bowel syndrome
  • Obesity and metabolic syndrome with insulin resistance; While in the intestinal flora of slim people bacterial types such as Bacteroidetes (Bacteroides, Prevotella etc.) predominate, the flora in obese people shifts towards Firmicutes (clostridia, lactobacilli etc.). Firmicutes can break down carbohydrates that are indigestible for humans, e.g. cellulose, into absorbable molecules, e.g. glucose. The result: obese people take in up to 10 percent more energy from the same food than slim people.

  • Fatty liver hepatitis (non-alcoholic steatohepatitis NASH)
  • IgA nephropathy (chronic disease of the kidney corpuscles)


  • Fatigue, decline in performance and loss of energy
  • Depressive moods
  • Chronic gastrointestinal complaints: diarrhea, constipation, flatulence, abdominal cramps, bloating, reflux and chronic inflammation of the gastric mucosa
  • Development of deficiency symptoms due to poor nutrient absorption or increased nutrient loss
  • Dysregulation of the immune system: susceptibility to infection, candidiasis, allergies, food intolerance and autoimmune diseases

Recognize leaky gut

I strongly recommend people with autoimmune diseases, allergies and susceptibility to infections who also suffer from gastrointestinal symptoms to check the protective function of the intestinal mucosa, which can be the cause of the chronic complaints. To diagnose a leaky bowel, you can send a stool sample to a specialized laboratory to check the following parameters:

  1. Intestinal flora analysis
  2. Secretory IgA: can be increased or decreased depending on the phase of the leaky gut syndrome. The value gives an initial overview of the function of the intestinal-associated immune system (GALT), whose task it is to prevent the penetration and settlement of potentially dangerous bacteria, viruses or fungi and to neutralize incompatible food components and toxins.
  3. Alpha-1 antitrypsin: serves to regulate inflammatory reactions. Elevated values ​​indicate a leaky gut (leaky gut syndrome).
  4. Zonulin: a valuable marker for a leaky gut

Gut Plus health check: microbiological analysis of the Intestinal flora, Molds, yeasts as well as the quantitative analysis for digestive residues, α-1 antitrypsin, Calprotectin, bile acids, pancreatic elastase, secretory IgA, Zonulin. Find out safely and comfortably from home whether a leaky intestine is behind your complaints! This also shows you whether your immune system is under strain. You can send the test result to my practice. I will evaluate it and, if necessary, create a therapy concept for symbiosis control.


In order to restore an intact barrier function in the intestine, it is advisable for the time being to avoid incompatible foods with an elimination diet until the prevailing symptoms have subsided. Above all, attention should be paid to intolerances that have not yet been noticed - mostly dairy products and wheat products. Therapeutic fasting often has a very good initial effect.

What to do at Leaky Gut?

In my practice, as a basic therapy for a leaky bowel, taking these three preparations in combination over a period of 3 months has proven to be very effective. They contain selected vitamins, micro- and phyto-nutrients that are guaranteed to be pure and free from colorings, preservatives and technical auxiliaries. In many patients suffering from leaky gut syndrome, symptoms such as flatulence, abdominal cramps and a feeling of fullness could be significantly improved as a result. At the same time, the quality of life increased because a balanced intake of micronutrients gave them more energy and a zest for life.

Darm Formula Plus, 90 capsules (3 packs for 3-month treatment)
Take 3 capsules daily with plenty of liquid. Combination preparation with extracts from black cumin, turmeric, black pepper, inulin from the chicory root, as well as vitamins B2 and niacin. Darm Formula Plus supports the well-being in the area of ​​the gastrointestinal tract and contributes to the maintenance of a normal intestinal mucosa.
L-Glutamine 3000, 30 sticks (3 packs for 3-month treatment)
Dissolve the contents of a stick (3 g) in plenty of water (approx. 250–300 ml) and drink every day.
Green tea extract, 60 capsules (2 packs for 3-month treatment)
For the first month, take 2 capsules a day between meals. From the 2nd month on, reduce to 1 capsule per day. Due to its astringent effect, green tea extract has been shown to reduce the permeability of the intestinal mucosa for antigens and prevent the penetration of antigens and harmful germs. In addition, the polyphenols contained are an effective antioxidant in the inflammatory process.

In addition, probiotics are used if dysbiosis is diagnosed. A good probiotic is:

Omni Lactis 10, 180 capsules (sufficient for 3 months)
For a cure-based intake over 3 months - shorter usually does not bring the desired success. Take 2 x 1 capsule daily with plenty of liquid about 30 minutes before a meal. With a total of 10 billion colony-forming, valuable bacterial units per daily dose (2 capsules).

Right nutrition

In addition to basic therapy and an elimination diet, which aims to track down incompatible foods, changing one's diet is another important pillar of treatmentwhich can help alleviate the symptoms of a leaky bowel. However, there is no such thing as a diet that is equally good for all those affected. Nevertheless, it has been shown that an above-average number of patients with leaky gut syndrome benefit from consistently avoiding certain foods or at least reducing them to a minimum.

Which foods should you avoid in Leaky Gut Syndrome?

  • Milk and cheese products, especially because of the milk sugar (lactose) it contains. Lactose-free dairy products are an alternative.
  • Cereal products, especially cereal products containing gluten such as wheat, spelled, rye, barley or green spelled. Alternatives are e.g. millet, buckwheat, amaranth or quinoa.
  • Foods containing lectin like whole grains, legumes, tomatoes or eggplant.
  • Fast food, which provides a lot of unhealthy carbohydrates and fats, is high in calories and also often contains (hidden) gluten.
  • Processed foodsthat contain additives such as emulsifiers, flavorings or sugar substitutes.
  • Refined “empty” carbohydratesthat are found, for example, in white flour, white rice, light pasta, table sugar and in general foods that have a high sugar content such as sweetened beverages (e.g. soft drinks), sweets, ketchup, bag soups and many other ready-made products.

For some sufferers of Leaky Gut Syndrome, some other carbohydrates and sugar alcohols also seem to be problematic: Although carbohydrate intolerance could not be proven, they react to special foods with the typical gastrointestinal complaints. What the carbohydrates have in common is that they are hardly or not at all absorbed in the small intestine, but are only further processed (fermented, fermented) in the large intestine by the bacteria of the intestinal flora. This group is also called FODMAP.

What is FODMAP?

The term “FODMAP” is made up of the first letters of the English words “fermentable oligo-, di- and monosaccharides and polyols”; so arefermentable multiple, double and single sugars as well as sugar substitutes such as sorbitol, xylitol and mannitol(Polyols) meant.

FODMAPS are found in different amounts in different foods. They are not generally harmful. Many of them even belong to the intestinal-healthy (prebiotic) substances because they serve as food for certain strains of intestinal bacteria that protect the mucous membranes.

Leaky bowel due to FODMAP?

However, some researchers believe that these FODMAPs can have an adverse impact on the intestinal barrier. Because they have found indications that the fermentation process can lead to an inflammatory reaction of the intestinal mucosa, which then promotes the development or exacerbation of a leaky gut syndrome.

Who Does FODMAP Diet Help?

That is why it is particularly recommended to those affected who tend to flatulence, stomach cramps and mushy stools or diarrhea to consistently eat a low FODMAP diet for a while. In irritable bowel patients, who mostly also suffer from leaky gut syndrome, the positive effect of a FODMAP diet has now been scientifically proven.

Which foods are high in FODMAP?

FODMAP-rich foods are e.g. certain types of fruit such as Apples, peaches, mango, plums, cherries or grapes (Oligosaccharides, fructose, polyols!), Some vegetables, e.g. Onions, garlic, cauliflower, mushrooms (Oligosaccharides, fructose, polyols!), But also Dairy products (Lactose!), Cereal products (Oligosaccharides) and sweeteners like Table sugar, corn syrup, mannitol (polyols!).

How does the FODMAP diet work?

Often times, a FODMAP diet is included in two phases Recommended: First, FODMAP-rich foods are completely avoided for six to eight weeks, then in the next step the various FODMAP-containing foods are gradually reintegrated into the daily menu in order to test them for their individual tolerance. If a food rich in FODMAP causes symptoms again, it should be consistently avoided in the future.

The reverse is also true: If there is no improvement, one should not hesitate to give up the FODMAP diet again - especially since many of the FODMAP-rich foods are intestinal-healthy foods because of their high proportion of prebiotics or fiber.

What to eat in Leaky Gut Syndrome?

If there is no intolerance, the following foods are beneficial for Leaky Gut Syndrome:

  • Good sources of L-glutamine such as fish, beets, potatoes, spinach or parsley.
  • Foods that are high in omega-3 fatty acids. These include, for example, edible oils such as rapeseed oil, hemp oil, linseed oil, walnut oil, fish such as tuna, mackerel and salmon, nuts and seeds, but also vegetables such as avocado.
  • Probiotic foods, especially yogurt, kefir, fermented vegetables and fermented tea (kombucha).
  • Prebiotic (fiber-rich) foods that help strengthen and multiply the protective intestinal bacteria - provided they are not problematic because of their FODMAP content (see above) but are well tolerated. These include buckwheat, millet, chicory, Jerusalem artichoke, salsify or (not too ripe) bananas. Or alternatively a prebiotic powder:

Colon Balance (30 daily servings of 10 g)
Stir 10 g of powder (1 measuring spoon) into approx. 100 ml of water and drink twice a day approx. ½ hour before eating. To support the settlement of bifidobacteria in particular, which form the healthy acidic flora in the intestine.
