Systemic inflammation throughout the body can cause many health problems and chronic diseases, and one way chronic inflammation occurs is through a gut health condition known as “leaky gut”. When the barriers of the digestive system are degraded and intestinal permeability is higher than normal, things like too-large food particles, microorganisms, and toxins that normally are unable to cross the digestive barrier into the bloodstream and the body as a whole are in fact able to do so. When this happens, the immune system goes on high alert and works to cleanup and detoxify the body, and the worse the condition of the mucosal and epithelial layers of the digestive barrier, the worse leaky gut is.
Leaky gut is most commonly a gut health condition that is experienced alongside other gut health problems like irritable bowel syndrome (IBS) or inflammatory bowel disease (IBD), but it can be experienced by itself, and leaky gut is often the first gut health problem that is experienced before other gut health problems develop. The tissues of the digestive system are highly dynamic and undergo cellular turnover quite rapidly, and at the same time the integrity of digestive barriers can degrade rapidly depending on what one eats, environmental or lifestyle stressors, and exposure to pathogens. What this means is that leaky gut can develop rapidly. Everyone has had leaky gut at least a few times in their life due to eating a poor diet, excessive stress, or illness, and while normally leaky gut will go away as everything returns to normal, leaky gut can persist if certain conditions remain.
Because leaky gut is characterized by excessive inflammation caused by chronic activation of the immune system, symptoms of leaky gut can be quite diverse, ranging from skin inflammation to joint pain to cognitive impairment to the typical digestive problems of bloating, gas, constipation, and/or diarrhea. To recover from leaky gut, digestive barriers must be restored to their normal integrity, and this can be done rapidly by fasting. By abstaining from all food and emptying the digestive system over the course of many hours or days, the presence of gut barrier degraders like food particles, gut microbiota, and toxic chemicals like pesticides are dramatically reduced and the digestive system is able to rapidly regenerate in a much quieter immune system environment. Combining fasting with stress reduction practices, certain herbs, and supplements like probiotics and zinc amplify the healing effect further.
Leaky gut can persist for a long time if left untreated and can set the stage for more serious gut health problems or inflammation-based diseases to develop, but it is relatively easy to treat when the right steps are taken.

Intestinal Permeability and Gut Health
The Role of Digestive Barriers
Digestion is the process that takes nutrients from the outside world and converts them into components usable by your body. As far as the human system is concerned, something is not truly in the human body until it has passed through the intestinal lining and into the bloodstream. Everything inside the digestive system is technically “outside” the cells and tissues of your body. The body wraps around this long, high surface area tunnel that end to end (mouth to anus) is exposed to the outside world, sealed by various gates (sphincter valves) along the way. All the food that is transiting through the gut, the acids and juices that are released into the gut, and the microbiome that reside in the gut all exist outside the human tissues of the body. For there to exist an outside and an inside there must exist a separator between the two; a wall, barrier, divider of some sort. In the case of the digestive system the linings of the esophagus, stomach, small intestine, and large intestine are that divider.
Digestive barriers exist for the following reasons:
To create a immune-silent environment inside the body, stopping viruses and pathogens from entering into the bloodstream and beyond
To limit the exposure of epithelial cells to chemically-reactive digestive juices like stomach acid, bile, and digestive enzymes
To differentiate and select nutrients usable by the body from those that aren’t fully digested and broken down small enough yet
To protect the body from unwanted chemicals and toxins, like environmental toxins such as pesticides or endotoxins produced from pathogenic bacteria

The Mucosal Layer
The digestive lining starts with a layer of mucus which sits over the one-cell-thick internal lining of the gut made of different types of epithelial cells. The mucosal layer is a chemical barrier that limits contact between the epithelial cells and the microbiome, which is of critical importance. Mucus also protects epithelial cells from the various digestive juices such as stomach acid, bile, and enzymes. Depending on the gut health of an individual, mucosal layers can be thick and healthy or eroded and unhealthy, and this can vary between the different sections of the digestive system.
In the context of leaky gut it’s typically the intestinal mucosal layer that is degraded, whereas an eroded mucosal layer for the stomach can lead to issues like gastritis and acid reflux (GERD). If the gut is healthy when viruses and pathogens in the digestive system make contact with the mucosal layer, there is a robust immune response from white-blood cells like T-cells and monocytes that occurs. Dysregulation of the mucosal immune response is a very important factor in the progression of gut health problems like leaky gut, irritable bowel syndrome (IBS), and more serious conditions like irritable bowel disease (IBD).
Epithelial Cells and Tight Junctions
Underneath the mucosal layer are epithelial cells, the main component of digestive linings. Once food particles are fully digested they pass through the mucosal layer and upon reaching the villi of the intestinal epithelium are transported across the cell membrane and into the bloodstream. Epithelial cells are wedged tightly together to stop things from passing in-between them, and the strength of these tight junctions are a key component of gut health.
The layers of the digestive system are selectively permeable, and the status of the mucosal layer and the epithelial cells determines intestinal permeability. The defining characteristic of leaky gut is that intestinal permeability has increased because the mucosal layer is thin and the tight junctions of the epithelium are degraded and gaps exist in-between the epithelial cells.
An increase in intestinal permeability allows food particles, chemicals, toxins, and microorganisms to pass from the digestive system into the body, which then triggers the immune system to clean up the “mess”. If digestive barriers are degraded and inflamed, restoring these digestive barriers to optimal health and function is one of the most important things that can be done to improve gut health. Restoring intestinal permeability to normal is the key to healing leaky gut.
Symptoms of Leaky Gut
Increased Intestinal Permeability
Leaky gut is a gut health condition characterized by increased intestinal permeability caused by eroded protective mucosal layers and an inflamed epithelial cellular layer. Leaky gut isn’t a health condition currently recognized to exist by the medical establishment, but its existence is undoubtable simply due to the sheer volume of people who suffer from health symptoms caused by increased intestinal permeability. Leaky gut can exist by itself as a gut problem, though more typically it is a gut health problem that exists concurrently with other gastrointestinal issues like IBS and IBD.
It’s the inflammation of the epithelium and the systemic response of the immune system that is primarily responsible for the symptoms of leaky gut.
Leaky Gut and Inflammation
By far the most notable symptom of leaky gut is that it triggers a constant inflammatory response in the body. It’s this inflammation that causes a lot of the symptoms commonly associated with leaky gut like:
Skin problems like acne, rashes, auto-immune skin issues
Joint pain, swelling, arthritis
Chronic fatigue and energy an overall deficit
Neurocognitive problems such as brain fog, anxiety, depression,
Asthma
Being caused by the inflammatory response of the body, when leaky gut is healed and inflammation goes down these symptoms can disappear quite rapidly.
More common are symptoms digestive in origin which themselves are effected by the inflammation leaky gut causes but are triggered primarily through mechanisms before the inflammatory response. These symptoms are:
Bloating and gas
Abdominal and stomach pain
Changes in gut motility like constipation and diarrhea
Food sensitivities and intolerances
Nutrient deficiencies
The body is always doing its best to heal itself, and with leaky gut it recognizes that its digestive barriers are functioning poorly, so it alters digestion how it can to help the digestive barriers heal. For example this could mean that if a meal is eaten that will make the leaky gut condition worse because it contains damaging foods, the transit of the food through the digestion system may be expedited and diarrhea experienced. Or since leaky gut is typically paired with some degree of microbiome dysbiosis, bloating from excess gas production of an overgrown pathogenic microbiome is common. As it is with gut health problems, the answer to the problem can be found in the symptoms experienced.
With leaky gut every meal feels like an unknown in whether symptoms will be triggered and which ones at that. The reason fasting is so effective in healing leaky gut is that it completely empties the digestive system of food, and food is one of the main triggers of leaky gut symptoms. Food may trigger symptoms of leaky gut, and certain foods can cause leaky gut, but leaky gut can be caused by factors other than food.

Things that Cause Leaky Gut
Pesticides and Leaky Gut
Pesticides are well-known to increase intestinal permeability and thin mucus linings. In the USA ~2.5 kg of pesticides (herbicides, insecticides, fungicides, bactericides, and rodenticides) are applied per hectare of land (100 x 100 meters). What this means is that most of the food sold in grocery stores is contaminated with significant amounts of pesticides. Excessive pesticide exposure also causes gut dysbiosis and unfavorably alters the gut-brain axis because pathogenic bacteria like Clostridium spp. and Salmonella, which produce noxious health-disrupting endotoxins, are more resistant to common pesticides like glyphosate (the herbicide roundup) than symbionts like Lactobacillus and Bifidobacteria.
Pesticide residues are found in high concentrations on many fruits and vegetables as well as wheat, oats, rice, beans, and legumes. Eating these foods, particularly wheat and oats in excess (multiple times per day), exposes the body to pesticide concentrations beyond tolerable and can contribute greatly to leaky gut.
Pathogens Increase Intestinal Permeability
Toxic pesticide exposure in excess will lead to gut dysbiosis, a condition marked by an increase in harmful pathogenic microorganisms in the gut microbiome while helpful symbionts decrease in population. Pathogens and the toxic metabolites they produce degrade digestive linings and increase intestinal permeability. An especially troublesome situation is when hard-to-dislodge pathogenic biofilms are able to adhere close to or directly onto epithelial cells because the mucosal lining is thin/non-existent. Biofilms are protective structures both symbiotic an pathogenic microorganisms make for a variety of reasons and to increase the survivability. In the worse cases of leaky gut the presence of pathogenic biofilms on the intestinal epithelium is almost assured, and this creates many complications.
Drugs and Antibiotics Increase Intestinal Permeability
Certain pharmaceutical drugs and antibiotics erode and degrade digestive linings. For example oral low-dose antibiotics are often prescribed for skin acne, and this daily antibiotic will slowly degrade digestive linings while simultaneously altering the microbiome towards gut dysbiosis. A short-course of antibiotics or certain drugs will also unfavorably alter intestinal permeability and the microbiome, but the effect is generally less than that caused from the constant use of these drugs, and can be recovered from quickly if the right steps are taken.
Stress/Anxiety and Leaky Gut
The gut-brain axis is a bidirectional connection pathway that exists between the gut microbiome and nervous system/brain, and not only does the microbiome effect the functioning of the brain, but conditions of the nervous system and brain like stress, anxiety, depression, insomnia, and more in-turn effect the microbiome and gut. Excessive stress and anxiety in particular degrade digestive function and the integrity of digestive barriers.
For example an extended stressful period of one’s life can lead to gut health problems like gastritis (stomach inflammation) and IBS. The depth of the connection between stress and the gut isn’t well-known by most, and it’s often a mystery to people who are experiencing gut health problems like leaky gut why they are having these problems; they never consider that the stress they are experiencing day by day may be a large contributing factor in their gut health problems.
Food Intolerances and Leaky Gut
A food intolerance occurs when the digestive system has a difficult time breaking down a particular food or chemical, and it can be common to be intolerant to many foods at once. When intestinal permeability is high and undigested food particles are slipping past epithelial tight junctions and into the bloodstream, then the immune system begins to recognize that certain food nutrients are constantly causing problems and a preemptive immune response can develop to those foods. If the body is having difficulty breaking down certain food macronutrients in the digestive track, like with fructose, lactose, or wheat proteins, then greater numbers of those nutrients will be not fully digested as compared to other food nutrients that are being adequately digested, and they will trigger the immune system strongly causing greater amounts of inflammation.
Food intolerances are highly individual, and it’s often hard to diagnose what food(s) is causing the digestive problems without first performing a few carefully observed 48+ hour fasts or with a 6+ week elimination diet.
The Case of Joe and Kate
To understand how all these leaky gut causing factors interplay with each other let’s examine a hypothetical scenario that unfortunately is all too common.
Joe and Kate eat a typical American diet high in wheat, other grain products, and ultra-processed foods. Their poor quality diet causes chronic inflammation of the digestive system (and body), and the high levels of pesticides they expose their gut and microbiome to through their diet exacerbate the problem more by further degrading digestive barriers and promoting the growth of pathogenic microorganisms. Both Joe and Kate take a few different pharmaceutical drugs for health conditions they have, and then when they mention that their developing gut health problems to a gastroenterologist they are prescribed a low-dose antibiotic, worsening the problem. Overworked and underpaid, the stress from each of their jobs bleeds over into their daily life, and one of the few ways they find comfort is by eating highly-pleasurable junk foods that trigger the food intolerances they’ve developed (but don’t yet know they have). With limited gut health consciousness, the health of their gastrointestinal systems and their overall wellness goes down day by day.
As you can see every factor is influencing the others, creating a feedback loop that degrades gut health further and further, and whereas leaky gut was the first and only gut health problem that existed, if things aren’t changed then eventually IBS and then IBD develops. If those conditions aren’t treated, then long term chronic diseases and cancers can develop. To unravel this knot of problems is no easy task, but one way significant progress can be made quickly is stop the downward spiral at the beginning and to abstain from all food for a period of time.
Fasting for Leaky Gut
There are many ways to reduce stress on the digestive system, from a liquid diet to removing intolerant foods from the diet, but there is no question that the simplest and most effective way to reduce digestive stress and inflammation is to simply not eat. The epithelial layer of the digestive system regenerates about 20% per day, and this rate is increased even further when the regular stress of digesting food is alleviated via fasting.
Luckily it’s in our physiology to fast, it’s a second “default mode network” for the body that has developed over millions of years of evolution. In fact the body wants you to fast every now and then, it’s the most efficient way to active autophagy, the cellular process that repairs and regenerates the tissues of the body.
With leaky gut the barriers of the digestive system are highly degraded and dysfunctional, and to heal leaky gut these tissues must be repaired and regenerated. Not only does fasting create an environment in the gut free of triggering food particles and greatly reduces microorganism populations, it also triggers this value process of autophagy which is essential in recovering from leaky gut. Leaky gut will not be remedied if autophagy isn’t activated, and autophagy is most powerfully activated by nutrient deprivation.
Intermittent Fasting for Leaky Gut
Most information out there that discusses how fasting can be used to remedy leaky gut focuses on daily 16:8 intermittent fasting. Most people eat every few hours, so food is constantly transiting through their digestive systems, and intermittent fasting changes this by condensing food consumption to an eight hour window (typically) with the other 16 hours of the day being free of all food consumption. Intermittent fasting is a good place to start for people brand new to fasting and interested in experimenting with fasting for gut health, metabolism, and overall wellness benefits. To see the biggest benefit from intermittent fasting, it should be done consistently everyday.
Intermittent fasting can certainly be effective in reducing leaky gut, but it can take a long time (weeks to months) to see beneficial changes because the digestive system is still processing food everyday. To really heal the gut and regenerate the digestive barriers quickly, the digestive system should be completely emptied of all food, and this takes 24+ hours of fasting. Longer fasts are much more effective in healing the digestive system, and intermittent fasting is a good protocol to follow in-between longer fasts to keep autophagy elevated.
OMAD for Leaky Gut
A 24 hour fast will take the body deeper into autophagy than intermittent fasting will, and it’s a good way to begin experimenting with fasting for healing leaky gut because it’s easy to perform with a little preparation and the beneficial effects are more likely to be felt and experienced. The best way to stick to something is to actually feel how it’s helping you, and guaranteed after a 24 hour fast if you pay attention you’ll notice that your gut health has noticeably improved and whatever symptoms you normally have have reduced in severity. Twenty four fasting can be done daily with what’s known as one-meal-a-day (OMAD) fasting. As has been shown intermittent fasting is useful for treating leaky gut, and OMAD is even more so.
48 Hour Fasting for Leaky Gut
Most effective for treating leaky gut significantly and quickly is a 48 hour fast. While not eating anything for 2 days may seem daunting, in fact a forty-eight-hour fast is short enough to be easily completed by most people without serious health issues as long as they have the willpower and do a little bit of planning. Remember the body is physiologically designed to go through periods of nutrient deprivation, and most people carry around enough body fat to make fasting for 48 hours, let alone a week or two, no problem. Abstaining from eating for 48 hours really clears the digestive system of all food and greatly reduces the size of the microbiome through nutrient deprivation. Symbiotic microorganisms are more adaptable to conditions of nutrient deprivation than pathogens and better survive the conditions an extended fast, and this makes fasting an excellent way to treat gut dysbiosis, which is often a main contributor to leaky gut.
Fiber and Fasting
The size and composition of the 1-2 meals before a fast is critical for the success of any fast. A final pre-fast meal rich in fiber with a balanced fat, carbohydrate, and protein macronutrient profile will provide long-lasting energy to the body during the first 24 hours of the fast, and once it has transited to the large intestine, the microbiome there will metabolize the fiber present into short-chain fatty acids and other useful metabolites which provide energy to the body and are useful for the brain for the next 24+ hours. It’s remarkable how much easier a fast can be when the last meal eaten is for example a grain bowl loaded up with fresh vegetables, versus a highly processed meal like pizza with glass. Fiber also normalizes gut motility and helps to remedy gut dysbiosis by promoting the growth of symbiotic microorganisms like Lactobacillus and Bifidobacteria.
I don’t recommend you try fasting off a low-quality meal. If you really want to heal your leaky gut you should make healing your gut a priority, make a plan, eat the right foods, and provide yourself the time you need. How well you stick to the plan is up to you and no one else.
For example when I do a 48 hour fast I will schedule it during the weekend so I have no outside responsibilities that require my energy or attention. I specifically set aside those two days for deep relaxation which reduces my stress levels, and the biggest physical activity I may do is go for a walk and practice some yoga/stretching. While fasting, keep physical and mental energy demands on the body low and dip into a deep state of parasympathetic relaxation and healing. This places less stress on the metabolic and energetic systems of the body and greatly reduces the chance of experiencing any unwanted side effects from fasting like low blood sugar and lightheadedness.
Before embarking upon your first fast I recommend you learn more about the nuances of fasting, either by reading my article on fasting to reset the digestive system, or by reading chapters 8 and 9 of the Holistic Gut Health Guide. You should also consult with a medical professional to make sure fasting will be safe for you to do.
Heal Leaky Gut in Two Weeks
By utilizing fasting and a few other gut health boosting strategies, significant progress can be made in healing leaky gut in just two weeks.
First and most important is to eat a very simple and gut health promoting diet during this period of time. Only organic/biodynamic foods should be eaten in order to reduce pesticide exposure, lifestyle and environmental stress should be reduced as much as possible, and the use of drugs/antibiotics should ceased if possible.
Diet to Reduce Intestinal Permeability for Leaky Gut
Different people can react to the same food quite differently, and for this reason I won’t give sweeping dietary advice, but there are a few best practices I am comfortable recommending which you can try and evaluate for yourself.
The first step is to increase your fiber and vegetable intake. Aim for 40+ grams of fiber in a day. A healthy symbiotic microbiome is critical in having healthy digestive barriers, and eating sufficient fiber and flavonoids is the main way to promote a healthy microbiome through dietary measures. Polyphenols and flavonoids are plant phytochemicals found in fruits, vegetables, and herbs that possess strong anti-inflammatory, antioxidant, and antimicrobial (for pathogens) properties. Flavonoids in particular are well-known to strengthen intestinal tight junctions, decrease intestinal permeability, and decrease gut dysbiosis, which are the exact things needed to heal leaky gut.
Second step is to eat more rice. Rice is a very easy grain to digest that can be prepared into a wide variety of meals, and I recommend eating rice over other grains when healing gut health problems like leaky gut. Organic rice will contain much less pesticides than non-organic rice, and rice flour is also the backbone of many gluten-free products.
Third step is to remove the most common food allergens from the diet, these being eggs, fish, milk, peanuts, shellfish, soy, tree nuts, and wheat. With some preparatory meal planning, it’s not difficult to eat a nutritious and filling diet without these foods.
Begin Fasting Regularly
Alongside these dietary changes you can begin experimenting with fasting regularly. Start with daily 16:8 intermittent fasting, and then on the easy days in your schedule add in some 24 hour and 48 hour fasts. One 48 hour fast for example will cause a huge improvement in your leaky gut condition, and during this focused two week effort to heal your leaky gut you should aim to complete two separate 48 hour fasts and a few 24 hour fasts. It is possible to keep caloric intake at maintenance while fasting, but if you have some body fat to lose then don’t worry about eating the same volume of food and let your body burn some body fat for energy as that’s beneficial for your health too.
Supplements and Herbs for Leaky Gut
Lastly the whole gut healing process can be helped along significantly by utilizing the gut healing and normalizing properties of herbs like black pepper, dandelion, and chamomile in addition to supplements like multi-strain probiotics and zinc. Herbs are so useful for gut health because they contain abundant amounts of useful flavonoid phytochemicals like apigenin, and a tea brewed from herbs like dandelion and chamomile contains no calories making it the perfect drink to enjoy during fasting. In fact a herbal tea like this makes fasting much easier metabolically and more effective in healing the gut via an upregulation of autophagy.
Black Pepper: One of the main chemicals found in black pepper is piperine, it’s the chemical responsible for black pepper’s pungency. Piperine is a gut health wonder chemical because it improves digestion by stimulating the body to release more digestive enzymes, restores healthy mucous linings, is antimicrobial against pathogens, increases the bioavailability and absorption of nutrients, reduces inflammation and mitigates stress, reduces the toxicity of certain chemicals, and boosts the metabolism. Black pepper and piperine by extension are great for gut health problems because not only does black pepper improve digestion and balance the microbiome, but it also aids in nutrient absorption, and many people who suffer from gut problems like leaky gut have problems absorbing the nutrients they consume.
Nootropics Depot sells a good piperine supplement which is useful taken with meals or during fasting. The main way I dose piperine is to simply grind extra black pepper on all my meals. Piperine makes up 3-10% of peppercorns by weight, so if you grind up enough black pepper, you’ll receive a significant amount (20+ mg) of piperine every time.
Dandelion Root: Dandelion is useful for fasting and healing gut problems because it normalizes gut motility (the speed of food transit through the gut), increases gastrointestinal mucus production thereby restoring protective mucous linings, applies beneficial antimicrobial pressures on pathogens in the microbiome, increases bile production (improving fat metabolism), and helps heal gastric ulcers. In addition to these amazing benefits, the phytonutrients found in dandelion help purify the blood of pathogens, reduce inflammation throughout the body, and heal blood vessel epithelial linings.
Dandelion also boosts fat metabolism, improves blood cholesterol parameters, and reduces unwanted platelet aggregation, which improves energy and oxygen transport throughout the body. Dandelion also aids the autophagy process by inducing unhealthy cells to undergo apoptosis while protecting healthy cells.
Dandelion is a wonder herb, use it often and you’ll be amazed by how much it helps you to heal your leaky gut.
Chamomile Flower: Chamomile is a digestive aid, calms the nervous system, and improves cardiovascular health. Chamomile is one of the best herbs for fasting and gut health because it improves gut motility, applies a gentle antimicrobial pressure to the microbiome, and increases gastrointestinal mucous production. Chamomile improves blood cholesterol levels, reduces excessive platelet aggregation, and normalizes blood sugar levels.
Chamomile is notably calming and increases the parasympathetic activity of the nervous system, which aids in relaxing and improving digestion. Balancing the activity of the autonomic nervous system is foundational to good health. Sometimes during a fast, energy levels will dip and become more volatile, and chamomile tea helps normalize metabolism and promotes relaxation, which smooths out the energy volatility that otherwise might have been experienced. The autonomic nervous system is also responsible for the waves of smooth muscle activity that propel food through the digestive system, and by normalizing these peristaltic waves, chamomile stabilizes gut motility to the Goldilocks zone, with food not transiting too quickly or too slowly through the digestive system
Mountain Rose Herbs sells organic dried dandelion root and chamomile flower which can be blended together into a 1:1 tea blend. Steep with boiling water for 5-15 minutes and drink daily to enjoy the gut health and overall wellness benefits it promotes. Drinking this tea in-between fasts with every or in-between meals is another way to keep autophagy increased and the gut healing.
Multi-Strain Probiotics: Probiotics containing strains of Lactobacillus and Bifidobacteria appear to be the most effective in helping with gut health problems, and these probiotic formations have also shown small but consistent benefits for those experiencing IBS. A multi-strain probiotic is usually more effective than a single-strain probiotic, and probiotics should be taken with a meal so more of the beneficial microbes survive the harsh acidic conditions of the stomach and can begin populating in the intestines, specifically the large intestine. I have used the following multi-strain probiotic from Nature’s Bounty successfully, I recommend you try it if you have leaky gut.
Zinc: Zinc has been shown to strengthen epithelial tight junctions, and you can consume more zinc by increasing your consumption of zinc-rich foods like oysters, pumpkin seeds, pulses (beans, lentils, etc), cashews, leafy greens, mushrooms, and avocado. You can also take a zinc supplement. Taking zinc in too high of doses (>25 mg) can cause digestive upset and nausea, and it’s for this reason I recommend the 15 mg Zinc Balance supplement from Jarrow Formulas. This Zinc Balance supplement also comes with 1 mg of copper which helps to keep zinc and copper levels balanced in the body.
Signs Leaky Gut is Healing
The clearest sign that your leaky gut is healing is that your gut motility normalizes and you experience much less bloating and gas after eating a meal. If you are having inflammatory health problems as a result of the leaky gut, then you’ll begin to notice that these issues are decreasing in severity and/or becoming less frequent. For example you might notice your skin clearing up, your brain fog go away, joint pain lessens in severity or vanishes, and chronic fatigue lessens.
These are the initial signs that leaky gut is healing, once intestinal permeability has returned to normal because the mucosal lining is restored and the epithelium is once again strong and intact, then you may notice that foods which previously triggered your leaky gut symptoms now no longer cause problems. To elaborate on this further I will describe how I healed my leaky gut and the changes I noticed.
How I Healed my Leaky Gut
Leaky gut was one of the many gut health problems I had for many years, alongside IBS, small intestinal bacteria overgrowth (SIBO), food intolerances to gluten and fructose, gut dysbiosis, and other issues. Yeah it was a handful, and my gut health problems are one reason I started Wild Free Organic.
Restoring the integrity of my digestive barriers was a key step in healing myself of my many gut health problems as leaky gut was one of the main contributing reasons to my IBS and food intolerances.
The main way I healed my leaky gut was by focusing on the following:
Fasting regularly with intermittent, 24 hour, and 48 hour fasts scheduled at regular intervals.
Constantly optimizing my diet to increase my vegetable and fiber intake. Introducing more fermented foods like pickles into my diet also helped considerably.
Reducing environmental stressors like pesticide exposure by shopping organic and by growing my own food. I also switched from drinking tap water which is bad for the gut microbiome to drinking only spring water free of added chemicals like fluoride and chlorine.
Reducing lifestyle stress by being more mindful of my energy levels and being careful with the intensity of the exercise I did, listening to my body and resting more when needed, and not letting factors beyond my control (like at work) stress me out needlessly.
