Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The overall goal of this proposal is to determine the role of the autonomic nervous system in the insulin resistant state associated with obesity and the metabolic syndrome. Obesity results from an accumulation of excessive fat deposit due to increase caloric intake or decrease energy expenditure, this condition is usually associated with diseases such as hypertension or diabetes, a cluster known as the metabolic syndrome. The first step in the development of the metabolic syndrome is a resistance to the action of insulin. The mechanism underlying insulin resistance in obesity is still unknown, however some investigators have proposed that the autonomic nervous system, particularly the increase sympathetic activation in obesity may play an important role. We have extensive experience studying the role of the autonomic nervous system in the cardiovascular alterations associated with obesity by producing complete autonomic withdrawal with a drug named trimethaphan. We propose to use the same approach to study the role of the autonomic nervous system in the development of insulin resistance in obesity.
