How does obesity contribute to hypertension?
Obesity might lead to hypertension and cardiovascular disease by activating the renin–angiotensin–aldosterone system, by increasing sympathetic activity, by promoting insulin resistance and leptin resistance, by increased procoagulatory activity and by endothelial dysfunction.
How does obesity cause hypertension pathophysiology?

Why is obesity a risk factor for diabetes?
In an obese individual, the amount of NEFA, glycerol, hormones, cytokines, proinflammatory substances, and other substances that are involved in the development of insulin resistance are increased. Insulin resistance with impairment of β-cell function leads to the development of diabetes.
What factors contribute to obesity in America?
