Is there a link between IBS and autoimmune diseases, such as celiac disease and inflammatory bowel disease? In this article, we explore the current scientific evidence supporting this connection, debunks common myths surrounding IBS as an autoimmune disorder, and provides practical advice for addressing gut symptoms that may indicate an underlying autoimmune condition.


Do you know someone who’s been diagnosed with irritable bowel syndrome (IBS)? If not, chances are you’ve experienced its symptoms yourself. Research shows that IBS affects up to 15% of the global population, making it one of the most common gastrointestinal disorders out there. But what if we told you that IBS might be linked to autoimmune diseases? In this article, we’ll explore the science behind this link, debunk common myths, and provide practical advice for addressing IBS while sheding light on underlying autoimmune conditions.

The link between IBS and autoimmune disease: what science says

While the causes of IBS are still not fully understood, scientists have long suspected that certain autoimmune diseases might play a role in its development. Autoimmune diseases are conditions in which the body’s immune system mistakenly attacks its own cells and tissues, leading to chronic inflammation and tissue damage. Some well-known autoimmune diseases include celiac disease and inflammatory bowel disease (IBD).

Several recent studies have shown that people with IBS have a higher likelihood of also having autoimmune diseases, and vice versa. For example, a 2020 study published in the journal Gut found that individuals with IBS were more likely to have celiac disease or IBD than those without IBS. Meanwhile, a 2019 study published in the Journal of Clinical Gastroenterology found that people with autoimmune diseases were more likely to have IBS-like symptoms than those without autoimmune diseases.

Exploring the connection between IBS and autoimmune disorders

So how might autoimmune diseases contribute to IBS symptoms? When the immune system is overactive or dysfunctional, it can trigger chronic inflammation in the gut, which can in turn cause abdominal pain, bloating, constipation, and other classic IBS symptoms. Moreover, certain autoimmune diseases – such as lupus, rheumatoid arthritis, and Sjogren’s syndrome – are known to cause gastrointestinal problems, including diarrhea, nausea, and vomiting.

Experts believe that the link between IBS and autoimmune disorders is complex and multifactorial, involving genetic, environmental, and lifestyle factors. Some researchers also suggest that IBS itself might be an autoimmune condition, in which the immune system mistakenly attacks the gut’s cells and tissues. However, the evidence for this theory is still inconclusive, and many experts argue that IBS should be classified as a functional, rather than autoimmune, disorder.

The debate on the classification of IBS as an autoimmune disease

One of the most contentious issues in the field of gastroenterology is whether IBS should be officially classified as an autoimmune disease. Proponents of this view argue that because chronic inflammation is a hallmark of both IBS and autoimmune diseases, and because people with IBS often have elevated levels of pro-inflammatory cytokines in their blood, it makes sense to consider IBS as a form of autoimmune disease.

On the other hand, skeptics of this view argue that while there is indeed some overlap between the symptoms and mechanisms of IBS and autoimmune diseases, they are fundamentally different kinds of disorders. For one, autoimmune diseases involve clearly identifiable autoantibodies and immune system dysfunction in specific organs or tissues, whereas IBS does not. Moreover, unlike autoimmune diseases, IBS does not usually have a clear genetic or familial pattern of inheritance.

Could IBS be a red flag for underlying autoimmune conditions?

Regardless of whether IBS is officially classified as an autoimmune disorder or not, it’s important to recognize that it can sometimes be a warning sign of other underlying autoimmune conditions. In fact, some people who are ultimately diagnosed with autoimmune diseases initially present with IBS-like symptoms.

As such, if you or someone you know has been experiencing chronic and persistent IBS symptoms, it’s worth getting checked for other autoimmune diseases such as celiac disease, IBD, or rheumatoid arthritis. Seeing a gastroenterologist or an autoimmune specialist can help rule out or diagnose potential underlying conditions.

Understanding the mechanisms by which autoimmune diseases trigger IBS

Scientists are still trying to fully understand the molecular and immunological mechanisms that link autoimmune diseases and IBS. One theory is that certain inflammatory markers, such as tumor necrosis factor-alpha and interleukin-6, might play a key role in triggering gut dysfunction and sensitivity in both conditions.

Another possible mechanism is the connection between the gut microbiome and the immune system. There is growing evidence that shifts in the gut microbiome, especially due to stress and certain foods, can activate the immune system and trigger chronic inflammation, leading to gut symptoms that resemble those of IBS and autoimmune diseases.

Demystifying the myths surrounding IBS as an autoimmune disorder

There are many myths and misconceptions surrounding IBS as an autoimmune disorder. Perhaps the most pervasive one is the idea that gluten sensitivity is the primary cause of IBS symptoms, and that eliminating gluten from your diet can cure IBS. In reality, while some people with IBS might have gluten sensitivity, it’s not the only or even the most common trigger of IBS symptoms. Other common triggers include stress, hormonal changes, certain foods, and bacterial infections.

Another myth is that IBS is purely a psychological disorder, and that it can be treated with therapy or relaxation techniques alone. While it’s true that stress and anxiety can exacerbate IBS symptoms, IBS is fundamentally a biological disorder involving complex interactions between the gut, the brain, and the immune system. As such, it typically requires a multidimensional treatment approach that combines diet, lifestyle changes, medications, and other interventions.


In conclusion, while the link between IBS and autoimmune diseases is still not fully understood, it’s clear that the two conditions are intimately connected in complex and multifactorial ways. Recognizing this connection can help promote better care and management of people with IBS and autoimmune disorders, and can inspire new research and treatments for both conditions.

If you or someone you know is struggling with IBS, don’t hesitate to seek medical care and support. You don’t have to live with chronic gut symptoms – there are many effective treatments and strategies available that can help you improve your gut health and live life to the fullest.
