Small intestinal bacterial overgrowth (SIBO) is where the bacteria in the large intestine overgrows up into the small intestine. This often, but not always, results in symptoms of bloating, constipation and/or diarrhoea and flatulence. Other common symptoms include acid reflux/ heartburn, brain fog, thyroid problems, rosacea, fatigue, weight loss, difficulty losing weight and much more.
Fibrous foods or typically ‘healthy’ foods tend to worsen symptoms of SIBO. Often probiotics can worsen symptoms too.
The great news is that resolving SIBO leads to a significant improvement of symptoms and usually allows you to enjoy a much more varied diet without the consequences!
The first step to addressing SIBO is identifying it. This lactulose breath test indicates the following:
- The severity of overgrowth (extent of small intestine affected & amount of gas produced)
- Type of overgrowth (methane, hydrogen or both)
