What condition is suggested by a patient who experiences dizziness upon standing, along with hyperpigmentation in palmar creases?

• A. Hyperthyroidism
• B. Diabetes insipidus
• C. Addison's disease
• D. Cushing's syndrome

Answer: (C)

The condition that is indicated by a patient experiencing dizziness upon standing, combined with hyperpigmentation in palmar creases, is Addison's disease. This condition, also known as primary adrenal insufficiency, occurs when the adrenal glands do not produce enough hormones, particularly cortisol and aldosterone. The symptom of dizziness upon standing, known as orthostatic hypotension, stems from the lack of aldosterone, which is responsible for regulating sodium and fluid balance. When the body is unable to retain sodium, blood volume decreases, leading to lower blood pressure and, consequently, dizziness when changing positions. Hyperpigmentation is another hallmark of Addison's disease, typically resulting from elevated levels of adrenocorticotropic hormone (ACTH) due to low levels of cortisol production. This excess ACTH can stimulate melanin production, which causes the darkening of the skin, particularly in areas such as the palmar creases. In summary, the combination of dizziness upon standing and hyperpigmentation strongly points toward Addison's disease, showcasing symptoms that reflect the dysfunction of adrenal hormone production.
