Fluid imbalance can be caused by various factors, such as:
Dehydration: Results from inadequate fluid intake or excessive fluid loss due to conditions like vomiting, diarrhea, or fever. Overhydration: Occurs due to excessive fluid intake or impaired excretion, often seen in renal failure or congestive heart failure. Electrolyte Imbalance: Imbalances in electrolytes like sodium, potassium, and calcium can disrupt fluid balance. Medications: Certain medications, such as diuretics, can affect fluid balance.
