There are a number of factors that can cause your gut flora to become imbalanced whilst travelling. These range from the stresses of travel to a change in your diet, the strains of bacteria that may be found in the local water and perhaps an increase in the number of alcoholic beverages. Maintaining a healthy and diverse gut microbiome during travel can be considered vital.
