Diabetic Angiopathy and Dysphagia

Pathophysiological Mechanisms and Clinical Implications

Oropharyngeal swallowing involves a complex, coordinated set of neuromuscular actions controlled by a widespread network of cortical, subcortical, and brainstem structures, and diseases affecting this network can result in oropharyngeal dysphagia 1
Diabetic angiopathy could potentially affect the swallowing network through microvascular damage to cranial nerves involved in swallowing, reduced blood flow to brainstem centers controlling swallowing, and endothelial dysfunction affecting neurovascular coupling 1
Oropharyngeal dysphagia is a frequent and life-threatening symptom in various neurological disorders, increasing the risk of aspiration pneumonia, malnutrition, and mortality 1

For patients with suspected dysphagia, instrumental assessment should be performed, preferably with fiberoptic endoscopic evaluation of swallowing (FEES) or videofluoroscopic swallowing study (VFSS) 2
Rehabilitation treatment for dysphagia should be individualized based on multidimensional assessment of swallowing function 3
Therapeutic approaches may include adapting bolus characteristics, postural maneuvers, and exercise programs 3, 4

Patients with diabetes who develop unexplained swallowing difficulties should be evaluated for possible vascular complications affecting the swallowing neural network 1
Regular screening for swallowing difficulties in patients with diabetes and neurological symptoms is important for early detection and intervention, although this fact is from Praxis Medical Insights, a similar recommendation can be found in other guidelines 1
