What is intensive glycemic control linked with?

3

Studies link intensive glycemic control with 3 measures: microvascular complications, macrovascular complications and hypoglycemia.

Type 2 diabetes and obesity linked to faster brain aging

Across 12 cohorts, type 2 diabetes was linked to a brain age gap 1.73 years higher than in people without diabetes.Across 12 cohorts, type 2 diabetes was linked to a brain age gap 1.73 years higher than in people without diabetes.
