Obesity in Australia :: Health, Diseases

Obesity is becoming a major health problem in developing countries like Australia, trade union America, Europe and other developing nations. The Australian Diabetes, obesity and life bolt study (AUSDIAB) predicts the changes in glucose indices health behaviour and incidence of diabetes in 5 year follow up experiments among 5842 participants (Barr et al., 2007). This study suggests that a large telephone deed of Australians suffered mortality due to cardiovascular diseases associated with abnormal glucose metabolism every year. The Framingham marrow squash Study revealed that hypertension, diabetes and left ventricular remodelling lead to the development of congestive substance failure (Levy et al., 1996). The Framingham tone Study also found that a 5% increase in weight increases the chance of hypertension by 30% over a four-year period of time. An change magnitude sympathetic activity, impaired renin- angiotonin system, keeping of fluid volume, peripheral vasoconstriction, dyslipidaemia, change magnitude blood viscosity due to the increased haematocrit and fibrinogen may increase pressure overload on sum of money in obesity (Schunkert, 2002). Several studies also suggest that the social movement of hypertension itself may contribute to left ventricular hypertrophy in round individuals as the increase of BMI increases the chance of hypertension (De Simone et al., 1994 Avelar et al., 2007). High dietetical fat intake increases the expression of angiotensin IB(AT1B) and Endothelin A (ETA) receptors (Neilsen et al., 2004 Zhang et al., 2005). Plasma concentrations of angiotensin II and endothelin 1 (physiological vasoconstrictor agents) were increased in both telling patients and animal models (Barton et al., 2000 Neilsen et al., 2004 Zhang et al., 2005). Recent studies have shown that reduced synthesis of nitric oxide (NO a major vasodilator) from L-arginine in endothelial cells is a major factor lend to the impaired action of insulin in the vascul ature of obese and diabetic subjects. Obesity results from an asymmetry between energy intake and expenditure. Growing evidence suggests that arginine plays an important type in regulating metabolism of energy substrates in mammals (Frank et al. 2007 Jobgen et al. 2006). NO is synthesized from L-arginine by NO synthase. As a signalling molecule, physiological levels of NO stimulate glucose uptake, as well as glucose and fatty-acid oxidation in skeletal muscle, heart, liver, and fat tissues (Jobgen et al. 2006). nitrous oxide also inhibits the synthesis of glucose, glycogen and lipid in liver and adipose tissues and enhances lipolysis in subcutaneous adipocytes (Jobgen et al.Obesity in Australia Health, DiseasesObesity is becoming a major health problem in developing countries like Australia, northwest America, Europe and other developing nations.

This study suggests that a large number of Australians suffered mortality due to cardiovascular diseases associated with abnormal glucose metabolism every year. The Framingham Heart Study revealed that hypertension, diabetes and left ventricular remodelling lead to the development of congestive heart failure (Levy et al., 1996). The Framingham Heart Study also found that a 5% increase in weight increases the chance of hypertension by 30% over a four-year period of time. An increased sympathetic activity, impaired renin-angiotensin system, computer memory of fluid volume, peripheral vasoconstriction, dyslipidaemia, increased blood viscosity due to the increased haematocrit and fibrinogen may increase pressure overload on heart in obesity (Schunkert, 2002). Several studies also suggest that the motion of hypertension itself may contribute to left ventricular hypertrophy in obese ind ividuals as the increase of BMI increases the chance of hypertension (De Simone et al., 1994 Avelar et al., 2007).

Obesity results from an asymmetry between energy intake and expenditure. Growing evidence suggests that arginine plays an important design in regulating metabolism of energy substrates in mammals (Frank et al. 2007 Jobgen et al. 2006). NO is synthesized from L-arginine by NO s ynthase. As a signalling molecule, physiological levels of NO stimulate glucose uptake, as well as glucose and fatty-acid oxidation in skeletal muscle, heart, liver, and adipose tissues (Jobgen et al. 2006). azotic oxide also inhibits the synthesis of glucose, glycogen and lipid in liver and adipose tissues and enhances lipolysis in subcutaneous adipocytes (Jobgen et al.
