Fluid overload and fluid deficit states can lead to which conditions?

Fluid overload and fluid deficit states can lead to which conditions?

• A. Hyperkalemia and hypokalemia
• B. SIADH and Diabetes Insipidus
• C. Anemia and leukopenia
• D. Osteoporosis and osteoarthritis

Answer: (B)

Fluid balance is controlled by antidiuretic hormone, which governs how the kidneys handle water. When there’s excess water in the body, you get dilutional hyponatremia as seen with SIADH, where too much ADH causes water retention. When there’s not enough water, you get hypernatremia from water loss, as with diabetes insipidus, where insufficient ADH leads to large volumes of dilute urine and dehydration. Because SIADH and diabetes insipidus directly illustrate how fluid overload and deficit affect body chemistry, they are the best fit for this question. Other options involve electrolyte disturbances or conditions not primarily tied to fluid balance.
