The metabolic syndrome consists of visceral obesity, hyperglycemia, hyperinsulinemia, dyslipidemia, and cardiovascular diseases. A common pathophysiological denominator underlying these epidemiological correlations has not been identified. However, the autonomic nervous system was shown to play a role in the metabolic syndrome. Recently, a prospective cohort study in 8,000 patients from 1987-1998 revealed a high relative risk to develop type 2 diabetes if autonomic dysfunction is present in healthy subjects independent from other risk factors, such as body weight.[42]
