What causes IBS is unknown. However, several factors are known to contribute to why IBS symptoms might occur in some people and not others:
People with IBS may have an imbalance of ‘good’ and ‘bad’ bacteria in their gut - this is sometimes called ‘dysbiosis’.
People with IBS may have a slightly inflamed or ‘leaky’ gut that is not readily detected on usual testing.
If you suspect you have IBS or regularly experience unacceptable gut symptoms please see your doctor or healthcare provider.
