Dehydration is the excessive loss of body water. There are a number of causes of dehydration including heat exposure, prolonged vigorous exercise, and some diseases of the gastrointestinal tract. Symptoms of dehydration include headache, lightheadedness, constipation, and bad breath. Treatment for dehydration is to replace lost fluids and electrolytes.
Dehydration: Causes and Prevention
Dehydration occurs when the body fluid loss exceeds the intake. If the lost fluid is not replaced, it will eventually lead to a decrease in fluid levels in the body, affecting normal body functions.
