Sarcopenia & Diabetic Foot Ulcers: Why Muscle Matters

This episode explains sarcopenia—the progressive loss of skeletal muscle—and how diabetes accelerates it, increasing risk of poor mobility, delayed wound healing, and higher mortality in patients with diabetic foot ulcers. Dr. G reviews the causes (insulin resistance, inflammation, ubiquitin–proteasome activity), clinical signs and tests, and practical treatments including resistance training, protein/leucine supplementation, vitamin D, and tighter glycemic control to preserve muscle and improve outcomes.
