There is a large amount of epidemiological and clinical evidence for associations among obesity, impaired glucose tolerance, and arterial hypertension; nevertheless, the pathophysiological mechanisms underlying these associations have not yet been elucidated. In this article, some working hypotheses are discussed, and original data are presented from two studies focusing on these pathophysiological interrelations. A case-control study of obese normotensive and hypertensive patients, matched for sex, age, and degree of overweight, has shown that obese patients with associated arterial hypertension have higher fasting serum insulin levels and reduced glucose tolerance compared with their normotensive peers. A second study compared subjects with impaired glucose tolerance with a control group of clinically healthy individuals of comparable sex, age, and body mass index, and it revealed that impaired glucose tolerance is associated with significantly higher blood pressure levels, independent of body weight. The results of the two studies together suggest that the association between hypertension and impaired glucose tolerance is independent of overweight; they also give some support to the hypothesis that hyperinsulinemia may contribute to the development of high blood pressure in obese patients.

Abstract
There is a large amount of epidemiological and clinical evidence for associations among obesity, impaired glucose tolerance, and arterial hypertension; nevertheless, the pathophysiological mechanisms underlying these associations have not yet been elucidated. In this article, some working hypotheses are discussed, and original data are presented from two studies focusing on these pathophysiological interrelations. A case-control study of obese normotensive and hypertensive patients, matched for sex, age, and degree of overweight, has shown that obese patients with associated arterial hypertension have higher fasting serum insulin levels and reduced glucose tolerance compared with their normotensive peers. A second study compared subjects with impaired glucose tolerance with a control group of clinically healthy individuals of comparable sex, age, and body mass index, and it revealed that impaired glucose tolerance is associated with significantly higher blood pressure levels, independent of body weight. The results of the two studies together suggest that the association between hypertension and impaired glucose tolerance is independent of overweight; they also give some support to the hypothesis that hyperinsulinemia may contribute to the development of high blood pressure in obese patients.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
