Hypercortisolism, also known as Cushing syndrome, is characterized by prolonged exposure to elevated cortisol levels, resulting in extensive physical changes and systemic complications. Physically, patients often develop central obesity, facial rounding (“moon face”), and supraclavicular fat pads. Skin manifestations such as thinning, easy bruising, and purple striae reflect cortisol’s catabolic effects on connective tissue. Musculoskeletal weakness, osteoporosis, and muscle wasting are common, arising from impaired protein synthesis. Cardiovascular complications, including hypertension and dyslipidemia, are frequently observed, as excess cortisol promotes sodium retention, vascular sensitivity to catecholamines, and altered lipid metabolism. Additionally, patients may experience glucose intolerance or diabetes due to cortisol’s antagonism of insulin action, significantly increasing cardiometabolic risk.
Beyond these physical consequences, hypercortisolism profoundly impacts overall health by disrupting immune, metabolic, and neuropsychiatric function. Immunosuppression predisposes individuals to infections, while psychological disturbances such as depression, anxiety, and cognitive impairment are prevalent. Sleep disruption and fatigue further diminish daily functioning. The disorder’s multisystem burden often leads to substantial morbidity, contributing to increased health care utilization and decreased productivity.
Even after achieving biochemical remission, patients remain at elevated long-term risk for adverse health outcomes. Studies by Valassi (2022) and Puglisi (2024) emphasize that comorbidities such as hypertension, diabetes, and bone loss often persist or incompletely resolve. Persistent fatigue, cognitive deficits, and mood disturbances can continue to impair quality of life years after remission. Moreover, overall mortality risk remains higher compared to the general population, underscoring the irreversible effects of chronic cortisol excess on cardiovascular and metabolic systems. Thus, effective management of hypercortisolism extends beyond hormonal normalization, requiring ongoing monitoring and treatment of residual comorbidities to improve long-term survival and well-being.
