Multiple diseases may arise or be exacerbated due to a leaky gut, including autoimmune diseases such as inflammatory bowel disease, celiac disease, autoimmune hepatitis, type 1 diabetes (T1D), multiple sclerosis, and systemic lupus erythematosus (SLE) (2–6).
Some studies show that leaky gut may be associated with other autoimmune diseases (lupus, type 1 diabetes, multiple sclerosis), chronic fatigue syndrome, fibromyalgia, arthritis, allergies, asthma, acne, obesity, and even mental illness.

Some research suggests leaky gut is linked with a higher risk of autoimmune diseases (such as lupus and multiple sclerosis) or chronic fatigue syndrome. But this is still just an association, and studies have yet to identify any cause and effect.
Many studies have revealed that a leaky gut paves the way to the development of autoimmune diseases. Therefore, healing the leaky gut suppresses the symptoms of these diseases; as such, decreasing its occurrence is vital to the prevention of autoimmune diseases [84,85].
If your intestinal wall has been compromised, and you have leaky gut, you'll likely experience these symptoms and signs: Digestive issues such as gas, bloating, diarrhea, or irritable bowel syndrome (IBS) Food allergies or food intolerances.
Blood or stool tests for zonulin can indicate the presence of leaky gut. Blood tests can also show potential causes of leaky gut: high histamine, low DAO, antibodies to intestinal cells, and immune activation to bacteria.
Dysbiosis, or bacterial imbalance, is a leading cause of the leaky gut syndrome. It means an imbalance between helpful and harmful species of bacteria in your gastrointestinal tract. Poor diet, comprising proteins found in unsprouted grains, sugar, genetically-modified foods (GMO), and dairy products.
Neurological conditions related to intestinal permeability
Studies have associated 'leaky gut' with the following conditions: schizophrenia. autism spectrum disorder (ASD) bipolar disorder.
A protein called zonulin is the only known regulator of intestinal permeability ( 3 , 4). When it's activated in genetically susceptible people, it can lead to leaky gut.
Leaky gut increases the intestinal translocation of endotoxins or other organic molecules, thereby promoting apoptosis. Most notably, leaky gut promotes the production of anti-dsDNA autoantibodies and immune complex deposition, ultimately leading to lupus exacerbation.
“Unfortunately, dysbiosis—or an imbalance between good and bad bacteria in your gut—has been associated with numerous diseases, including autoimmune diseases like Crohn's and ulcerative colitis, psoriasis, lupus, and multiple sclerosis,” she says.
'LEAKY GUT' MIGHT BE AN EARLY WARNING SIGN OF CROHN'S DISEASE, NEW RESEARCH SHOWS. No one knows exactly what causes Crohn's disease, a chronic, inflammatory condition in which the body's immune system mistakenly attacks the digestive tract, causing such symptoms as diarrhea and abdominal pain.
“Leaky gut can happen quickly depending on your diet, medications and stress,” says Dr. La Vella. “The good news is the gut can also heal quickly with stress reduction, eating well and not taking medications that damage the gut or weaken the mucosal lining.”
We recommend staying on the diet for at least 3-4 weeks as it will take about that long to “heal the gut.” Some patients may take up to 3 months to reestablish a normal functioning intestinal mucosa. In my experience, everyone who goes through this process feels better in the end.
Stress and depression can increase gut barrier permeability. The result, a 'leaky gut,' allows bacteria to seep into circulation, producing an inflammatory response. Indeed, both depression and stress can provoke heightened inflammation [17,18] and gut leakiness [19••,20].
You can also manage a leaky gut when you eat foods rich in omega-3 fatty acids like fish, seaweed, nuts, and seeds. Omega-3 assists in reducing inflammation, which is often the reason for the leaky gut symptoms.
Increasing clinical and preclinical evidence implicates the microbiome as a possible key susceptibility factor for neurological disorders, including Alzheimer's disease, autism spectrum disorder, multiple sclerosis, Parkinson's disease, and stroke.
Leaky gut syndrome, or increased IP, can cause uncomfortable symptoms, such as constipation, diarrhea, and bloating. People who think that they may have leaky gut syndrome can try making dietary changes to manage their symptoms. Not everyone responds in the same way to different foods.
Disorders of gut-brain interaction are thought of as pain-central or pain-predominant disorders, although patients can experience other perceptive symptoms or abdominal symptoms such as bloating or nausea. Disorders of gut-brain interaction are associated with a constellation of abdominal-perceptive symptoms.
Research has shown that a leaky gut is a warning sign for an autoimmune disease. In individuals who have genetic predispositions, a leaky gut may trigger the initiation and promote an environment for autoimmune diseases like Hashimoto's.
There is a strong correlation between thyroid and gut health. Studies have shown that low thyroid hormones can lead to leaky gut and poor gut health can suppress thyroid function. Optimal digestion actually helps to tame the antibodies associated with autoimmune conditions such as Hashimoto's and Graves.
