Introduction:

Dehydration happens when your body loses more fluid than you take in. When the normal water content of your body is reduced, it upsets the balance of minerals (salts and sugar) in your body, which affects the way that it functions. Dehydration can be mild, moderate, or severe depending on how much of the body’s fluid is lost or not replenished. When it is severe, dehydration is a life-threatening emergency.

Causes:

Dehydration can be caused by losing too much fluid, not drinking enough water/fluids, or both.

Your body may lose too much fluid from:
  • Excessive sweating
  • Excessive urine output
  • Hot weather conditions
  • Active lifestyles
Dehydration in Infants and Elderly:

Infants and children are more likely to become dehydrated than adults because they weigh less and their bodies have a faster turnover of water and electrolytes. The elderly and people with illnesses are also at higher risk.

Signs and symptoms:
  • Increased thirst
  • Dry mouth
  • Concentrated/yellow urine
  • Dizziness
  • Lethargy
  • Restlessness
  • Confusion
