Dehydration

Dehydration means the body does not have enough water to carry out its normal processes.

Most susceptible to serious dehydration are young children with fever, vomiting, and diarrhea. In adults, some medications increase urination and can lead to dehydration. Anyone exercising vigorously, especially in hot weather, can quickly become dehydrated.

Symptoms include extreme thirst; dry mouth; infrequent, dark-colored urine; dizziness; and confusion. Young children may have sunken eyes, cheeks, and soft spot on top of the skull.

Severe dehydration is a serious medical emergency that can lead to heat stroke, kidney damage, seizures, coma, and death. Take the patient to the emergency room or call 9-1-1.

Diagnosis is made through blood tests and urine tests.

Mild dehydration can be treated simply by drinking extra water, or water with electrolytes such as sports drinks. More serious cases may be hospitalized for intravenous fluids.

It's important for anyone who is outside in hot weather, or who is ill, to drink extra fluids even before feeling thirsty as thirst is not always a reliable guide.

Top Symptoms: fatigue, dizziness, vomiting or diarrhea, racing heart beat, being severely ill

Urgency: Hospital emergency room
