The main objective of the study is to assess the sensitivity of the salivary cortisol dosage at 23 hours compared to the serum cortisol dosage at 8 am after overnight 1-mg dexamethasone suppression test (Suppression of serum cortisol <1. 8 μg/dL ) as the reference method for the detection of ACIC in obese subjects

Official title: Detection of Infra-clinic Cortisol Adenoma (ACIC) in a Population of Android Obese With High Metabolic Risk: Contribution of Salivary Cortisol at 23 Hours

Study design: Allocation: Non-Randomized, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Diagnostic

Primary outcome: Number of patients with positive salivary cortisol dosage among patients with positive serum cortisol dosage

Secondary outcome:

Number of patients with negative salivary cortisol dosage among patients with negative serum cortisol dosage

Comparing the results of salivary cortisol dosage and serum cortisol dosage

Comparing the results of the two salivary samples

Number of patients with metabolic complications of obesity among patients with ACIC

Number of patients with severe type 2 diabetes among patients with ACIC
