What it means
Dehydration occurs when your body loses more fluid than you take in, impairing normal bodily functions. Causes include insufficient fluid intake, vomiting, diarrhea, fever, excessive sweating, and certain medications such as diuretics. Signs include dark urine, dry mouth, headache, dizziness, fatigue, and decreased urination. Severe dehydration can cause confusion, rapid heartbeat, and fainting and is a medical emergency. Older adults, young children, and people with chronic illnesses are at higher risk. Mild dehydration is treated with oral fluids and electrolyte drinks. Moderate to severe dehydration may require intravenous fluids in a healthcare setting.
