Dehydration – Overview
Dehydration occurs when the body loses more fluids than it takes in, leading to an insufficient amount of water to function properly. Water is essential for every cell, tissue, and organ, and dehydration disrupts key bodily processes, including temperature regulation, circulation, and waste removal. It can range from mild to life-threatening and affects people of all ages, especially infants, older adults, and those with chronic illnesses.
Mild dehydration may cause headaches, dizziness, fatigue, and dry mouth. In more severe cases, dehydration can result in low blood pressure, rapid heartbeat, confusion, or unconsciousness. If left untreated, it can lead to serious complications, such as kidney failure, heatstroke, or seizures.
Dehydration
The body loses fluids through sweat, urine, faeces, and even breathing. Dehydration can occur when you don’t drink enough water or lose too much due to diarrhoea, vomiting, fever, or excessive sweating. Climate, physical activity, and health conditions all influence fluid requirements.
Recognising the early signs and responding promptly by increasing fluid intake is crucial. In more severe cases, especially in vulnerable groups, medical attention may be necessary. Treatment usually involves rehydration with oral fluids or intravenous fluids in emergency situations.
In summary, dehydration is a potentially serious condition that can often be prevented or treated early with proper fluid intake. Awareness, early recognition, and timely action can help prevent complications and support overall health.
