Irritable Bowel Syndrome. It is likely you, or someone you know suffers from it, given that more than 7% of Australians have IBS. But have you heard of PI-IBS? What is that?
What is PI-IBS?
PI-IBS stands for Post Infectious Irritable Bowel Syndrome. It happens after an infection, such as gastroenteritis, or food poisoning (such as salmonella or campylobacter) occurs. Whilst most individuals recover, with no further issues, unfortunately, some people go on to develop IBS. Research indicates that risk of development is increased two fold when psychological factors, such as chronic stress or anxiety, and adverse life events occur in the months prior to infection.
As with IBS, it is characterised by cramping, abdominal pain, bloating, wind, constipation and diarrhea. It is a chronic condition, meaning long term management is required.
What causes PI-IBS?
Inflammation as a result of infection is one way the body reacts as part of the immune response. PI- IBS may result in a delay in turning off this response. Other research indicates that changes to the nerves in the gut as a result of infection may result in development of IBS symptoms, such as altered bowel movements and pain.
How to manage it?
As with other types of IBS, management comes down to a range of lifestyle and dietary factors.
Firstly though, ensuring the infection is dissolved is the first step. This may just mean a matter of time, or for some people taking antibiotics.
For many people, trialling a low FODMAP diet can make management much easier. This is done through removal of all high FODMAP foods, then reintroduction of certain high FODMAP foods to determine triggers. Common high FODMAP foods include milk, onion, garlic, mushrooms, cauliflower, apples and pears.
Management of stress is essential when it comes to managing IBS. Be this through regularly being physically active, participating in yoga or meditation, or practicing mindfulness skills, reduced stress often means reduced symptoms. Getting enough sleep and fostering positive, healthy relationships can also result in less stress.
What about probiotics?
Probiotics may play a role in managing IBS, however it is important to get to the bottom of what is continuing to cause it. Probiotics may help with re-establishing the healthy bacteria in your gut, however if sensitivity has developed (particularly in relation to food), probiotics alone are unlikely to be enough to manage it.
It is important to remember that sensitivity is likely to change over time; for some people, sensitivities may change during or after pregnancy, or even seasonally.
For most people a bout of gastro or food poisoning is likely to be just that, however for some susceptible individuals, PI-IBS may develop. Management with stress reduction, and dietary modification is the best way of managing this.
