Possible causes for irritable bowel syndrome

Irritable bowel syndrome (IBS) is a chronic disease of the intestine that causes recurrent abdominal pain and discomfort. In the Western world 10–20 % of the population are affected.


What are FODMAPs?

The term FODMAP is an acronym, derived from "Fermentable, Oligo-, Di-, Mono-saccharides and Polyols". It is the generic term for certain kinds of short-chain carbohydrates that are poorly absorbed while they travel through the small intestine.

Sugars: A small compendium

If you suffer from certain kinds of carbohydrate malabsorption you are often confronted with names of chemical compounds – it is often very easy to become confused. Therefore, we put together a small compendium that can be used, whenever needed.

Simple sugars

Glucose, a simple sugar; is the most important energy source in humans. It is readily absorbed in the small intestine. It is also known as grape sugar, corn sugar or dextrose.
Fructose FODMAPFructose
Fructose is a simple sugar that is slowly absorbed in the small intestine. The absorption rate is highest when equal amounts of glucose and fructose are present. When the amount of excess fructose is too high, fructose can reach the colon where it is fermented by bacteria.
Galactose is a simple sugar that occurs in foods like dairy products. In the small intestine, galactose is transported by the same carriers as glucose, therefore, the absorption is very fast.
