can lack of hydration cause stomach cramps

During a run, cramps or stitches can seriously hamper your performance. If the cramping continues hours after running, however, it can lead to more serious problems. Dehydration does not cause cramping, but cramps can easily lead to dehydration, either through diarrhea or because stomach pain prevents you from drinking enough.
