• The most important thing to do with diarrhea is to rehydrate yourself with clean water. To provide essential minerals, it is necessary to resort to oral rehydration solutions or ORS (to provide automatically before departure and to put in your emergency kit). Otherwise, you can mix 6 teaspoons of powdered sugar with a teaspoon of salt in a liter of drinking water. The interest of cola remains controversial, but if it is the only drink available of which we are sure (encapsulated bottle), it is better to take it than to drink nothing!

• Until the transit is regularized, a diet based on rice, pasta, semolina, well-cooked carrots, is essential. On the other hand, intestinal antiseptics have not provided proof of their effectiveness. And antidiarrheals are not recommended, except in special situations (such as very complicated access to the toilet for example): they are even contraindicated in the event of fever and blood in the stool because this severe diarrhea may require antibiotic treatment. .
