👉 Fluid, or bodily liquids, are essential for maintaining the body's homeostasis and various physiological functions. The primary causes of fluid imbalance include dehydration, which occurs when the body loses more fluids than it takes in, often due to inadequate water intake or excessive sweating, heat exposure, or vomiting and diarrhea. Conversely, fluid overload happens when the body retains too much water, typically due to conditions like heart failure, kidney disease, or excessive salt intake. Both scenarios disrupt the delicate balance of electrolytes and blood volume, impacting vital organs and processes.
