Overview

Metabolic syndrome syndrome must be differentiated from other diseases that cause hypertension, obesity, and hyperandrogenism, such as Cushing's syndrome and pseudo-Cushing's syndrome.

Differentiating Metabolic Syndrome from other Diseases

The table below summarizes the findings that differentiate pseudo-Cushing's disease from other conditions that may cause hypertension, hyperandrogenism, obesity, facial plethora, skin changes, osteoporosis, nephrolithiasis and neuropsychiatric conditions.
