What term describes insufficient amounts of fluid in the tissues?

The term that describes insufficient amounts of fluid in the tissues is dehydration. Dehydration occurs when the body loses more fluids than it takes in, leading to a deficit of water necessary for normal bodily functions. This condition can affect various systems, resulting in symptoms such as dry skin, dizziness, and fatigue. It highlights the crucial balance of fluids in the body, as adequate hydration is essential for maintaining cellular processes and overall health.

In contrast, the other terms relate to fluid balance in different contexts. Overhydration refers to an excessive intake or retention of fluids, which can lead to complications, while hydration simply indicates the state of having an adequate fluid level. Fluid retention denotes a condition where excess fluid builds up in the body, often leading to swelling, usually in the extremities. Understanding these distinctions is important for recognizing and managing fluid-related health issues.
