👉 Losing fluids, or dehydration, occurs when the body loses more fluids than it takes in, leading to an imbalance that can affect various bodily functions. This can happen due to insufficient water intake, excessive sweating, vomiting, diarrhea, or even certain medical conditions. When the body loses too many fluids, it can result in symptoms such as dry mouth, dizziness, fatigue, and dark-colored urine, highlighting the critical need to maintain adequate hydration levels to ensure proper bodily functions.
