Understanding Dehydration: Causes, Symptoms, and Prevention
This article provides an in-depth overview of dehydration, highlighting its causes, symptoms across different age groups, and key prevention tips. Learn how dehydration impacts your health and who is most at risk, with practical advice to stay properly hydrated and avoid serious complications.

Dehydration occurs when the body loses or uses more fluids than it takes in, disrupting normal bodily functions. Insufficient water intake can lead to physiological imbalances, making hydration essential. While anyone can experience dehydration, vulnerable groups such as children and seniors are more susceptible. Recognizing early signs is key to prevention. Symptoms vary by age: children may show dry mouth, irritability, and sunken fontanelles, while adults might experience intense thirst, dark urine, fatigue, and confusion. Common causes include inadequate fluid intake, diarrhea, and vomiting. Higher risk groups include athletes, those at high altitudes, and individuals with chronic illnesses. Stay hydrated, especially during physical activity or in hot climates, to maintain health.
