Riverside Health System answered:Dehydration may be caused by not drinking enough water, losing too much fluid or both. Any of the following may increase your chance of having dehydration:
- advanced age with decreased ability to sense thirst or to concentrate urine
- being in the sun or heat for too long, or sweating a lot, such as when you exercise
- diseases, such as stroke, diabetes, heart problems or infections
- medicines that cause you to lose water and salt, such as diuretics (water pills)
- vomiting, diarrhea or fever that lasts a long time

When the amount of fluid you lose (usually from sweat) exceeds the amount you drink, you can become dehydrated. It can cause fatigue, nausea, vomiting, headache and, in severe cases, loss of consciousness. Dehydration occurs when you lose 2% to 3% of your body weight in fluid. This means that if a 150-pound man loses three or more pounds during exercise, he reached a state of dehydration during that activity.When the amount of fluid you lose (usually from sweat) exceeds the amount you drink, you can become dehydrated.
