Constipation can occur while traveling, especially on a long car ride or plane flight. Dietary changes are also a big factor, as well as the fact that you are away from your regular routine. During vacation, it’s important to try and keep up with your regular schedule and to follow your bowel movements closely. You should also avoid eating too much fatty foods and high-sugar foods like candy, cookies and ice cream. It’s also a good idea to get plenty of exercise, especially if you sit for a long time while on the road or in transit.
