3. Constipation
Dehydration is one of the most common causes of constipation. That’s because dehydration causes stool to become dried out, which in turn prevents it from passing through the bowels.
Drinking more water is actually one of the best ways to solve constipation, as is consuming any food that is high in oils such as fish or avocado – this can help to lubricate the stool and encourage it to pass.
Prunes are the best of all though. Not only does the insoluble fiber break up the trapped stool but the sorbitol content causes the stool to absorb more fluid.
