Definition & Meaning of "dehydration"

What is "dehydration"?

Dehydration is a condition that occurs when the body loses more fluids than it takes in, leading to a lack of balance in the body's water levels. This can happen due to factors like intense sweating, vomiting, diarrhea, or not drinking enough fluids. Symptoms of dehydration may include thirst, dry mouth, dark-colored urine, fatigue, and dizziness. Serious dehydration can be dangerous and may require medical attention, including receiving fluids through a vein to restore hydration levels. Preventing dehydration involves drinking plenty of fluids, especially during hot weather or when engaging in physical activity.
