Pathophysiology and Management of Type 2 Diabetes Mellitus Bone Fragility

Area of Science:

• Endocrinology
• Metabolic Bone Disease
• Diabetology

Background:

• Type 2 diabetes mellitus (T2DM) is linked to elevated fragility fracture risk.
• This risk persists even with normal or high bone mineral density (BMD), suggesting impaired bone quality.
• Current BMD assessments are insufficient for T2DM fracture risk evaluation.

Purpose of the Study:

• To review the complex pathophysiological mechanisms behind T2DM-related bone fragility.
• To highlight factors affecting bone health in T2DM patients.
• To inform improved fracture risk detection and treatment strategies.

Main Methods:

• Literature review summarizing existing evidence.
• Analysis of pathophysiological pathways affecting bone in T2DM.
• Synthesis of factors contributing to skeletal fragility.

Main Results:

• T2DM bone fragility results from multifactorial influences.
• Factors include inflammatory cytokines, hormones, incretins, H2S, cortisol, and altered metabolism.
• Hypoglycemia, falls, and certain antidiabetic medications exacerbate fracture risk.

Conclusions:

• Bone quality, not just density, is critical in T2DM fracture risk.
• Understanding T2DM's complex effects on bone is crucial for clinical management.
• Further research into T2DM bone fragility mechanisms can improve patient outcomes.
