This study aimed to assess the frequency of acromegaly in patients with poorly controlled type 2 DM.<h4>Methods</h4>This cross-sectional study included 504 patients (mean age: 57.7 ± 10.8 years) with uncontrolled type 2 DM (HbA1c > 8%) despite at least 1 year of insulin treatment (insulin alone or oral anti-diabetic drugs together with insulin). Here, INS is linked to acromegaly.
