Severe Dehydration

Severe dehydration happens when your body doesn’t have enough water and essential fluids to function properly. It can be life-threatening and requires urgent medical care. This condition can result from various factors, including excessive fluid loss or inadequate fluid intake.

Key Definitions

• Dehydration: Loss of more fluids than are taken in.
• Severe Dehydration: A critical level of dehydration with significant health risks.

Pathophysiology

Structure

Dehydration affects every system in the body. Water is crucial for maintaining blood volume, regulating temperature, and facilitating digestion and nutrient transport.

Blood

When dehydrated, blood volume decreases, leading to thicker blood. This makes it harder for the heart to pump blood, reducing oxygen and nutrient delivery to tissues.

Nerve Supply

Nerve cells require adequate hydration to function. Dehydration can disrupt nerve signals, leading to confusion?, dizziness?, and impaired cognitive function.

Types of Dehydration

1. Isotonic Dehydration: Equal loss of water and salt.
2. Hypertonic Dehydration: More loss of water than salt.
3. Hypotonic Dehydration: More loss of salt than water.
