👉 A deficit fluid refers to a condition where the body's fluid balance is negatively impacted, often due to inadequate intake or excessive loss of fluids. This can result in symptoms like dehydration, dizziness, fatigue, and impaired cognitive function. Deficit fluid can arise from various factors including inadequate water consumption, excessive sweating, vomiting, diarrhea, or certain medical conditions that affect the body's ability to retain fluids. Managing and addressing these deficits through proper hydration, dietary adjustments, and sometimes medical intervention is crucial for maintaining overall health and bodily functions.
