What is dehydration in the context of bodily fluids?

Dehydration refers to a condition where there is an insufficient amount of tissue fluid within the body. This can occur when the body loses more fluids than it takes in, leading to a deficit in the fluids necessary for proper physiological functions. Adequate tissue fluid levels are critical for maintaining cellular functions, nutrient transport, temperature regulation, and waste removal.

When the body is dehydrated, it can impact various systems, leading to symptoms like dry mouth, fatigue, decreased urination, and dizziness. Understanding dehydration in this context emphasizes the importance of maintaining proper hydration for overall health and bodily functioning. Other options like excess tissue fluid, normal levels, or fluid overload indicate conditions that reflect an abundance of fluid, which contrasts with the state of dehydration.
