What is a FODMAP diet?

FODMAP is an acronym for Fermentable, Oligo-saccharides, Di – saccharides, Mono-saccharides, And Polyols.


A FODMAP diet might be appropriate for you if you are experiencing symptoms such as:

·        Abdominal pain or discomfort

·        Bloating and distension

·        Wind or flatulence

·        Change of bowel habit (diarrhoea and/or constipation)


If you have not done so already, it is important that you contact your GP in order to rule out other causes for your symptoms.  A FODMAP diet will only be supported if you have had received all medical investigations to rule out any underlying medical conditions.


In order for you to have a balanced nutritional intake your diet should consist of proteins, carbohydrates and fats.  A FODMAP diet relates to the carbohydrates.  There are some carbohydrates that are difficult to digest and are not absorbed by the large intestine.   Your large in intestine is colonised by billions of bacteria that ferment FODMAPs.  This results in the production of gas which sometimes causes wind and bloating. 


Some people may also experience diarrhoea which is due to an osmotic effect that has been created in the bowel due to the presence of FODMAPs.  Water is drawn from the surrounding cells and into the bowel causing diarrhoea. 


Following a diet low in FODMAPs for a set period of time can alleviate the above symptoms.


What will the process involve?


You will need to follow the low FODMAP diet for 4 – 8 weeks as closely possible in order for the diet to work. We will help you map a diet that is as close to your usual intake as possible and will provide you with alternatives to foods that you are eliminating.  You may find that you might not need to eliminate all of the FODMAPs; this will be determined with your dietitian.


After the elimination period has been achieved you will then be advised to reintroduce foods containing FODMAPs to identify which carbohydrates you are able to tolerate.  People have different sensitivities to FODMAPs therefore your FODMAP plan will be unique to you, maximising your nutritional intake. 


You will be provided with booklets and fact sheets as well as unlimited emails to a dietitian whilst you are going through your elimination and re-introduction phase of your diet.
