Acute ingestion of a high-fructose drink impairs vascular autonomic modulation and reflex control of blood pressure in first-degree relatives of diabetic patients

First-degree relatives of diabetes patients, despite being euglycemic, presented impaired BRS and exacerbation of sympathetic modulation after ingestion of a high fructose drink when challenged to orthostatic stress. This finding alerts the importance of early autonomic dysfunction even in clinically healthy people, especially in face of a stressful situation.
