Dehydration Gut Cramps
Dehydration gut cramps are abdominal pain and nausea when sweat losses beat fluid and sodium—plain water alone often is not enough on long hot runs.
Dehydration gut cramps are abdominal stitches and nausea when sweat losses outpace fluid and sodium replacement—gut motility and absorption both suffer. Plain water alone can worsen nausea in long hot runs if sodium lags.
Weigh before and after training in similar weather to estimate needs.
Common questions
-
Can overhydrating plain water cause gut cramps too?
Yes—diluting sodium (hyponatremia risk) also upsets the gut. Match fluids to thirst and include sodium on multi-hour efforts in heat.
