When the low FODMAP diet doesn't work.

Updated: Apr 8



The low FODMAP diet can work brilliantly to reduce gut symptoms such as bloating and excess gas and gut pain and diarrhoea and/or constipation if you are reacting to FODMAPs (small, poorly digested carbohydrates such as fructose).


Sometimes the low FODMAP diet doesn't work!


Or only partially works with significant residual gut issues still occurring on a regular basis.


Possible scenarios:


1. SNEAKY FODMAPs or OTHER GENERAL NON FODMAP FOOD TRIGGERS


Maybe there are some sneaky high FODMAP foods causing issues: best to troubleshoot with an experienced Dietitian in FODMAPs PLUS food intolerances (see why later).


General non FODMAP triggers such as meal size, stress, inadequate fibre or fluid, poor sleep, triggers such as chilli can also be considered. And stress- did I mention stress?


2. YOU ARE NOT SENSITIVE TO FODMAPS


Maybe FODMAPs are actually fine for you and not causing your gut symptoms, and maybe the symptoms are not related to food.


It is super important to check with your GP and/or gastroenterologist to rule out medical conditions such as endometriosis, Coeliac Disease, Inflammatory bowl disease and any other medical issues that can cause the same symptoms as IBS.


3. YOU HAVE UNIDENTIFIED FOOD INTOLERANCE(S) CONTINUING TO CAUSE ISSUES


Gut or IBS symptoms can be caused by other food intolerances such as dairy or wheat intolerance and/or it can be due to other components in food such as food chemicals (salicylates, amines and glutamates as well as some food additives) .



If the low FODMAP diet has not helped or has only partially resolved symptoms, it may be worth exploring these other food intolerances especially if you feel you have symptoms related to food.
