Unfamiliar food, changing time zones, and different climates are the most common causes of constipation when travelling. Exotic ingredients and spices, unusually large quantities and rich food, combined with a change in daily routine and perhaps higher temperatures than normal, also put a strain on the stomach and bowels. Depending on the type of changes and your body’s natural predisposition, needing a few days to acclimatise to the new conditions is completely normal. To make the adjustment easier, eat light, fiber-rich meals and, particularly in warmer climates, drink more than you normally would at home.
Lack of Fluids
Digestion is often negatively affected by lack of fluids in warm holiday regions: if you sweat more, you should also drink more in order to balance things out.
Medication or food supplements high in iron can slow down digestion when travelling. Also, most travel sickness medication contain high quality of aluminum which cause constipation.
If possible, ask your doctor or pharmacist about alternatives when travelling.1
Some people generally find it difficult to go to the toilet outside of their usual environment. If the main issue in that case is cleanliness, toilet paper for the toilet seat or sanitary wipes are good solutions.2
