Explanation

Excessive thirst or polydipsia is a hallmark symptom of Diabetes Insipidus, a condition where the kidneys cannot conserve water due to lack of ADH (antidiuretic hormone) or kidney resistance to it. Hyperthyroidism causes increased appetite and heat intolerance. Pheochromocytoma causes episodic hypertension. Cushion's syndrome (likely Cushing's syndrome) causes weight gain and moon face. The extreme thirst specifically points to Diabetes Insipidus.
