👉 Lack of fluid, or dehydration, occurs when the body does not have enough water or other essential fluids to function properly. This can happen due to various factors, such as inadequate water intake, excessive sweating, vomiting, diarrhea, or certain medical conditions. When the body lacks sufficient fluids, it struggles to maintain proper blood volume, regulate body temperature, transport nutrients and oxygen, and flush out waste products. As a result, symptoms like dry mouth, dizziness, fatigue, dark urine, and decreased urine output may appear, indicating the body's inability to maintain its optimal state due to insufficient hydration.
