Verified step by step guidance

Begin by understanding the term 'dilutional hyponatremia'. Hyponatremia refers to low sodium levels in the blood, and 'dilutional' indicates that this condition is due to an excess of water diluting the sodium concentration.

Next, review the function of antidiuretic hormone (ADH). ADH is responsible for regulating water balance in the body by controlling the amount of water reabsorbed by the kidneys.

Consider the role of ADH in Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH). In SIADH, there is excessive release of ADH, leading to increased water reabsorption by the kidneys.

Understand how SIADH leads to dilutional hyponatremia. The excessive water retention causes the sodium in the blood to become diluted, resulting in low sodium levels.

Compare SIADH with other endocrine disorders listed. Addison's Disease involves adrenal insufficiency, Diabetes Insipidus is characterized by insufficient ADH leading to excessive urination, and Cushing's Syndrome involves excess cortisol. None of these directly cause dilutional hyponatremia like SIADH does.
