What is SIBO?

SIBO is an abbreviation for Small Intestinal Bacterial Overgrowth.

SIBO is a serious condition affecting the small intestine which occurs when bacteria that normally grow in other parts of the gut start to grow in the small intestine. They don't necessarily even need to be unhealthy bacteria, it's just that they're in the wrong place. 

One of the many roles of our gut bacteria is to help us digest food. They do this by fermenting carbohydrates which produces by-products of gas like methane and hydrogen. This build-up of gas in the small intestine can cause uncomfortable and distressing symptoms.

What are the symptoms of SIBO?

Common symptoms of SIBO can include any one or a multiple of the following: 

  • A feeling of fullness in the gut, especially after meals

  • Abdominal pain and/or cramps

  • Bloating, usually higher up in the abdomen and slightly under the ribs 

  • Indigestion

  • Flatulence

  • Constipation and/or diarrhoea

  • Nausea

  • Food sensitivities 

What causes SIBO?

It can sometimes be difficult to find the exact cause of SIBO and it's estimated that around 60% of IBS sufferers actually have SIBO. It may be related to several factors, such as:

  • Poor detoxification (elimination of unwanted substances and waste from the body)

  • Imbalance of gut bacteria where healthy bacteria are being over-run by less friendly, pathogenic bacteria

  • 'Leaky' gut, or impaired integrity of the gut lining 

  • Damage to the vagal nerve, poor gut motility and impaired digestion 

  • Stress, anxiety or poor mental health where there is chronic activation of the 'fight or flight' stress response

  • Poor immune function

  • History of antibiotics or use of other certain medications such as PPIs

  • Previous history of food poisoning or gastroenteritis-type illness

Is there a treatment for SIBO?

SIBO can be treated using various different methods and it is essential to identify the underlying factors that may have caused it, as otherwise it is likely to recur again in the future. 

A simple breath test done at home can help to identify whether or not you have SIBO and which type so that the appropriate treatment can be given. 

Foreshore Nutrition provides professional, qualified support through a staged treatment protocol to help you eradicate SIBO and lessen the risk of relapse. 

Treatment may include:

  • Dietary protocol using the SIBO biphasic diet to starve the gut bacteria 

  • Herbal anti-microbial therapy to 'kill off' the bacteria in the small intestine 

  • Gut barrier repair and support 

  • Vagus nerve stimulation and gut motility work 

  • Stress reduction techniques

  • Repopulation of healthy gut bacteria 



As a qualified SIBO Practitioner, I can assess you for SIBO, help you to identify which type you have, which factors may be causing it and address it using a tailored treatment plan specific to your individual needs. 

Don't suffer in silence....these symptoms can be extremely debilitating and uncomfortable, having a huge impact on your daily life. Too often people live with this for many years thinking it's something they just have to put up with.
