Approaches to calm mast cells have shown promise in treating IBS. In addition to the findings from the samples taken from the gut lining, blood samples have also indicated changes in inflammation in IBS patients.

These types of increases in these immune cells suggest an increased immune activation within the gut of those with IBS. Another symptom that can indicate the presence of inflammation is called visceral hypersensitivity.

This is where the nerves along the gut lining are more sensitive which can lead to increased pain. As mentioned already, the increased presence of mast cells in the gut of those with IBS can contribute to this increased sensitivity.

When these cells are activated, they can release compounds such as histamine and cytokines which then stimulate an inflammatory response and contribute to IBS inflammation. Visceral hypersensitivity can be seen in a similar way to sunburn.

In sunburn, the impact on the nerves in the skin leaves them with increased sensitivity. This means that the same amount of pressure applied to the skin before sunburn feels different to the same pressure applied after sunburn. This increased sensitivity can also happen in the gut as the result of an inflammatory or immunological response.

Calming the immune response by focusing on mast cell health as well as reducing the inflammatory process can help reduce symptoms of visceral hypersensitivity. Postinfectious IBS is IBS that starts after a gut infection or food poisoning.

When compared, the risk of developing postinfectious IBS appears to be higher in those with bacterial gastroenteritis than in those with viral gastroenteritis. In those who do develop postinfectious IBS, samples taken from the lining of the digestive tract show an increased level of a cytokine called IL-1β.

This is a chemical messenger of the immune system that contributes to inflammation. This was not increased in those who experienced gastroenteritis but did not go on to develop postinfectious IBS. It was also noted that levels of IL-1β were higher during the active infection in those who went on to develop postinfectious IBS when compared to those who did not.

This indicates a greater susceptibility to inflammation in those who developed IBS after an infection. The symptoms of postinfectious IBS are the same as what is typically seen in IBS.

These symptoms include:. The rates of developing the diarrhoea subtype of IBS may be more common than constipation following an infection [Source: Pubmed ]. Postinfectious IBS can lead to changes and imbalances in the gut microbiome. The changes may then contribute to ongoing inflammation in the gut, creating an ongoing cycle.

One key finding was the reduction in microbial diversity in those with postinfectious IBS. Microbial diversity is understood to indicate the strength and stability of the gut microbiome. For example, the more diverse the gut microbiome is, the more stable it is and the less likely symptoms are to be present.

While reduced diversity indicates a less stable microbiome and one that is more likely less resilient and less healthy. Alterations in the balance of the gut bacteria have also been noted with increases in Bacteroides and Prevotella bacteria frequently reported.

Due to the role of the gut microbiome in regulating the immune response and the inflammatory processes, gut bacteria imbalances referred to as dysbiosis can alter gut function. The combination of these factors can perpetuate ongoing and low-grade inflammation in the gut. Research into probiotic supplements has been shown to alleviate symptoms of IBS.

This is in part due to the ability of probiotics to stabilise and balance the gut microbiome as well as reduce inflammation. E-cigarettes and vaping have been shown to lead to damage to the gut.

This has been shown by damaging the gut lining, leading to the gut being more susceptible to infections as well as increased inflammation. Studies have also shown that following repeated vaping of e-cigarettes exposure to E. Coli leads to higher infectivity as well as higher levels of inflammation.

Interestingly, nicotine itself has been found to have an anti-inflammatory effect. This was confirmed in studies that found nicotine and nicotine-free liquids to impact the gut to the same extent.

Vaping can often be seen as a healthy alternative to smoking cigarettes , however, from a gut perspective, it can have a damaging effect leading to increased levels of inflammation and increased susceptibility to infections. Various psychological factors are strongly linked with the development of IBS.

This includes childhood abuse and PTSD, both of which are associated with the development of IBS in later life. Stress has been shown to act in a way that increases inflammation.

This is via stimulating proinflammatory signals in the gut. This is shown in research that linked mood disorders to ongoing inflammation. This inflammation can potentially be systemic throughout the body or located in the brain.

As mentioned, early-life abuse and PTSD have both been shown in increase inflammation and also dysregulate certain parts of the central nervous system and increase the rick of developing IBS. Mindfulness and meditation practices have been studied for their ability to reduce inflammation.

This calming practice has been shown to reduce levels of faecal calprotectin, a test that measures gut inflammation.

This was understood to be due to the ability to calm the gut-brain connection and how that can improve the immune balance in the gut. Leaky gut is also known as increased intestinal permeability. This refers to changes in the permeability of the gut lining.

In some situations, such as during exercise, increased permeability of the gut lining is a normal and healthy response. However, in others, ongoing permeability can contribute to symptoms.

Increased inflammation in the lining of the digestive tract can increase the permeability of the gut lining which can alter how it functions. This can be an ongoing issue in the presence of inflammation. It has also been found that a sub-group of IBS patients have increased intestinal permeability.

This may be due to the breakdown of the tight junction proteins. This breakdown of the mucosal barrier the gut lining by inflammatory cytokines may then allow for the immune system to be in closer proximity to the foreign proteins travelling through the digestive tract.

This includes food proteins as well as bacteria and viruses. Faecal calprotectin is a common test that is used to measure inflammation in the digestive tract. Calprotectin is produced in the gut at sites of inflammation. This is then transported out of the body in stool and levels are measured in a stool sample.

This test for inflammation can help to differentiate between IBD inflammatory bowel disease and IBS. Calprotectin can be elevated in some IBS patients, however, the levels are not high as in IBD. The biggest question is whether or not a leaky gut may cause problems elsewhere in the body.

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. However, we do not yet have clinical studies in humans showing such a cause and effect.

Although it is unusual to hear the term "increased intestinal permeability" in most doctors' offices, alternative and integrative medicine practitioners have worked on gut healing as an initial step to treat chronic diseases for decades.

Other cultures around the world often recommend specific diets to make people feel better. Even in the United States, it is common to see people changing their diets after getting sick. A common initial step some practitioners take is to remove foods that can be inflammatory and could promote changes in the gut flora.

Among the most common are alcohol, processed foods, certain medications, and any foods that may cause allergies or sensitivities. Controversy still exists on whether leaky gut causes the development of diseases outside the gastrointestinal tract in humans. However, it is always a good idea to eat a nutritious, unprocessed diet that includes foods that help quell inflammation and avoids foods known to trigger inflammation , which may, at least in theory, help to rebuild the gut lining and bring more balance to the gut flora.
