What disease is associated with excessive production of hydro-cortisone?

Cushing's disease is indeed associated with excessive production of cortisol, specifically from an adrenal tumor or pituitary gland disorder. This condition leads to an overabundance of hydrocortisone, which can result in a variety of symptoms, such as weight gain, hypertension, and changes in skin appearance, including thinning and easy bruising.

On the other hand, Addison's disease involves insufficient production of adrenal hormones, particularly cortisol and aldosterone, leading to symptoms such as fatigue and low blood pressure. Hyperthyroidism and hypothyroidism pertain to the thyroid gland and involve the overproduction or underproduction of thyroid hormones rather than cortisol. Hence, Cushing's disease is the only condition among the options that correlates specifically with an overproduction of hydrocortisone.
