Vestibular Stimulation as a Modulator of Metabolic Function: Implications for Diabetes Mellitus Management

Metabolic disorders, including diabetes mellitus and obesity, continue to pose a major public health challenge. Diabetes is a disorder of glucose metabolism that can be associated with vestibular dysfunction. Traditionally, vestibular stimulation (VS) is used to reduce motion sickness and enhance balance and coordination. Recent studies show that the benefits of VS may extend beyond motor and sensory functions to include significant effects on metabolic health. VS may improve metabolic health by enhancing insulin sensitivity, reducing cortisol levels, and increasing heart rate variability by increasing parasympathetic dominance and decreasing sympathetic tone. This may be helpful for patients suffering from metabolic disorders. VS is connected to the brainstem, hypothalamus, and cortex. It aids in metabolic control by stimulating insulin secretion through activation of the vagus nerve, a visceral nerve that supplies the pancreas. VS may improve metabolic homeostasis by modulating hypothalamic pathways and interacting with hypothalamic centers involved in the regulation of food intake and body weight. Despite these promising findings, the precise neural and physiological mechanisms linking vestibular function to metabolic health remain poorly understood, and systematic research in this area is limited. The purpose of this review is to summarize the relationship between VS and metabolic regulation, identify gaps in existing knowledge, and explore its potential as a novel non-pharmacological intervention for metabolic disorders.
