High blood pressure

More than 85% of those with hypertension have a BMI greater than 25, although diet is probably a more important factor than body weight. The association between obesity and hypertension has been found in animal and clinical studies, which have suggested that there are multiple potential mechanisms for obesity-induced hypertension. These mechanisms include the activation of the sympathetic nervous system as well as the activation of the renin–angiotensin–aldosterone system. As of 2007, it was unclear whether there is an association between hypertension and obesity in children, but there is little direct evidence that blood pressure has increased despite increases in pediatric overweight.
