Dehydration occurs when your body loses too much fluid. This can happen when you stop drinking water or lose large amounts of fluid through diarrhea, vomiting, sweating, or exercise. Not drinking enough fluids can cause muscle cramps. You may feel faint. Usually your body can reabsorb fluid from your blood and other body tissues. But by the time you become severely dehydrated, you no longer have enough fluid in your body to get blood to your organs, and you may go into shock, which is a life-threatening condition.\nIf you become mildly to moderately dehydrated while working outside or exercising:\nStop your activity and rest. \nGet out of direct sunlight and lie down in a cool spot, such as in the shade or an air-conditioned area. \nProp up your feet. \nTake off any extra clothes. \nDrink a rehydration drink, water, juice, or sports drink to replace fluids and minerals. Drink 2 qt (2 L) of cool liquids over the next 2 to 4 hours. You should drink at least 10 glasses of liquid a day to replace lost fluids. \nRest and take it easy for 24 hours, and continue to drink a lot of fluids. Although you will probably start feeling better within just a few hours, it may take as long as a day and a half to completely replace the fluid that you lost.

It could be so many things ranging from simple to more complicated.  Only your doctor can diagnose it for sure.  Take heart though, as most of the time it is nothing.  If he is very athletic, he can have this from dehydration regardless of the fact that he drinks a lot.  \n\nPlease let the doctor handle the diagnosis and the care.  He is more qualified than anyone in here.  He has also seen and examined your son.

Dehydration is a significant factor in hangovers, but there's a lot more going on chemically and physiologically than just water loss. This link to hangovers in how things work tells as much of the story as we currently understand. It's not pretty!\nhttp://health.howstuffworks.com/hangover1.htm There is still quite a bit about the body's response to alcohol and the other fermentation and distillation byproducts that we don't understand very well.

Some medications dehydrate you.  You should tell your doctor and also maybe get checked for diabetes.  You really should ask your doctor though that is the best advice I can give you.

Like everything else they have changed what our water requirements should be.  Now they are saying that you should only drink water when your body wants it.  I learned \na long time ago that you watch your urine.  If it's clear then you water intake is good, If it has color  to it then you are dehydrating.\n\nGood Luck

You need electrolytes in addition to water. Try a slice of fresh lemon in a glass of water.

Mostly, you just let it run its course.  As some of the other answers pointed out, try to get plenty of fluids, much more than you think you need.  With the typical vomiting and diarrhea, you can become dehydrated VERY quickly without knowing it.

All of it. Your skin and hair get dry and your organs don't work as effectively. Your brain loses essential fluid and contracts, causing the headaches that come with dehydration sometimes.
