Fluid maintenance refers to the process of ensuring that the body maintains a proper balance of fluids, which is essential for overall health. This involves monitoring and managing the intake and output of fluids, including water, electrolytes, and other essential substances. Proper fluid maintenance helps prevent dehydration and supports vital bodily functions, such as circulation, digestion, and temperature regulation. In medical settings, fluid maintenance is crucial for patients who may be unable to consume adequate fluids on their own. Healthcare professionals often use intravenous (IV) fluids to provide necessary hydration and nutrients. This practice is especially important for individuals undergoing surgery, experiencing illness, or recovering from injury, as it helps maintain optimal homeostasis and promotes healing.
