How to Diagnose Cushing's Disease

Cushing's disease is a hormonal disorder caused by prolonged exposure to a hormone called cortisol. It is a rare disease, and most commonly effects adults 20-50 years old. Obesity, Type 2 diabetes, poorly controlled blood sugar levels, and high blood pressure all increase the risk of Cushing's. The signs and symptoms of Cushing's vary with each case, but most patients present with some of the most common signs.
