IBS and Exercise

Updated: Mar 9

Is your exercise routine supporting your IBS or triggering your IBS?

Regular exercise is considered an essential part of living a healthy lifestyle, so how could exercise make you feel worse? When it comes to IBS, some types of exercise can help with symptoms, but others can actually make symptoms worse.

The reality is, most people with IBS are already living healthy lifestyles, eating well and exercising regularly. But as gut symptoms worsen, unexplained weight gain often comes along with it.

While not exercising enough is detrimental to your health, too much in terms of frequency, duration or intensity can also negatively impact your gut health and healing.

This is because exercise that is too strenuous can lead to dysregulated cortisol (stress hormone), immune system suppression (around 80% of the immune system is in the gut) and intestinal hyperpermeability (leaky gut). All of which can impact IBS sufferers.

The number one rule to follow if you’re trying to overcome gut issues, is that exercise is only helpful to you if it’s not an added stressor. If you leave a workout session feeling like you could take a nap, it’s probably not a good thing. If you leave feeling refreshed and ready to get on with your day, this is likely the perfect amount for you. Less is more.

One type of exercise which is notorious for triggering digestive symptoms is long-distance running or bike riding. Both of these have been associated with diarrhea episodes and can lead to cortisol dysregulati
