Why do we get diarrhoea?
We get diarrhoea because the intestines, very long tubes located in the stomach, swell. There is more liquid inside and it cannot be absorbed. The cause is the repeated infections caused by a type of microorganisms. They are creatures that can only be seen by a microscope.
In the case of children such troubling microorganisms vary by country, season of year and age. The microorganism that affects Catalan children has more affect in winter and in children less than three years old.
