Could Your Probiotics Be Worsening Your IBS?

I have seen firsthand the impact that probiotics can have on individuals with irritable bowel syndrome (IBS). While probiotics are often recommended as a means of improving gut health, they may actually make IBS symptoms worse for some people.

IBS is a complex condition with a variety of potential triggers, and the underlying causes are still not well understood. However, recent research has shed some light on the potential risks associated with probiotic supplementation.

One reason why probiotics may exacerbate IBS symptoms is due to the sheer diversity of strains and species available. A 2021 study published in the Journal of Clinical Gastroenterology found that the efficacy of probiotics in treating IBS may depend on the specific strains used [1]. In some cases, probiotics can even lead to bacterial overgrowth and worsen symptoms such as bloating, gas, and diarrhea [2].

Another possible explanation is the fact that probiotics can alter the gut microbiota, which can have unintended consequences. While some studies have suggested that probiotics may help balance the microbiome, others have shown that certain strains can disrupt the delicate balance of beneficial and harmful bacteria, leading to further gut inflammation and discomfort [3].

Furthermore, individuals with IBS often have a compromised gut barrier, which allows bacteria and other harmful substances to pass into the bloodstream. This can trigger an immune response and exacerbate symptoms such as abdominal pain and diarrhea. A 2018 study published in the journal Gastroenterology found that some probiotics can actually increase gut permeability, exacerbating the underlying issue [4].

In my clinical experience, majority of my patients cannot tolerate probiotics well and they worsen majority of their IBS symptoms. I rarely recommend probiotics, because the reality is that, while probiotics may be beneficial for some individuals with IBS, they may also worsen symptoms for others. It is essential to work with a healthcare provider to identify the underlying cause of symptoms and determine whether probiotics are a safe and effective treatment option. In some cases, other strategies such as dietary changes, stress management, and medication may be more appropriate.

If you're ready to take the next step towards better gut health, email me and let's work together to develop a personalized plan that meets your specific needs and goals. Say goodbye to guesswork and hello to feeling your best. I look forward to hearing from you soon!

In health,
