    Fructose malabsorption can manifest in many ways including bloating, abdominal pain, nausea, diarrhoea, constipation are all common symptoms. If these symptoms occur regularly after ingesting certain foods particularly fruits & vegetables then this could be investigated.
    Hydrogen breath testing can determine the degree of the problem & then a consultation with a Dietitian to advise on dietary changes would be recommended.

    The symptoms are usually bloating, wind, abdominal pain, diarrhoea and/or constipation. This is due to the fructose sugar being poorly absorbed in the small intestine and it being fermented by bacteria to produce gas.   I often commence my clients initially on a low FODMAP diet, and then challenge back fructose, lactose, polyols, FOS and GOS, and I always emphasise the importance of a high fibre diet.  It is important to seek the advice of an experienced accredited dietitian.

    The two usual ways of finding out if you're intolerant to fructose are:

    (1) Try a fructose-free diet for 4 weeks or

    (2) Do a hydrogen breath test first to see if fructose intolerance might be contributing to your symptoms; this test is not “easy” in the sense that it requires testing at least 2 to 3 sugars on different days, with breath samples taken every 20 minutes for up to 3 hours on each day, and it costs around $100 per sugar tested with no medicare rebate. It is normal to malabsorb fructose when taken in large amounts, but some people malabsorb more than others, and some people get symptoms whilst others don't (because of bowel hypersensitivity and/or increased motility of the bowel).

    Fructose is found in foods like apple, pears, grapes, watermelon, asparagus, leek, onion, honey … ideally, see a dietician to look at other aspects of your diet - as fructose is only one of the FODMAPs. The following document gives more information about fructose containing foods:
