Obesity is proven cause of hypertension. Although high blood pressure is a highly treatable, if left untreated its consequences are severe, and hypertension is a strong predictor of more severe CVD.
Nearly two-thirds of people who are obese are at risk of high blood pressure. The combination of obesity and hypertension is associated with an increased risk of cardiac failure due to thickening of the ventricular wall and increased heart volume.
Studies have been observed that both weight and weight gain are positively associated with the development of hypertension in adulthood. Obesity seems to lead to coronary artery disease is first to cause some of the other problems such as abnormal blood cholesterol levels or high blood pressure.
Raised blood pressure changes the structure of the arteries. As a result, risks of stroke, heart disease, kidney failure and other doses increase. There are several mechanisms through which obesity causes hypertension.
Hyperinsulinemia, which is common among overweight and obese individuals, can cause activation of the sympathetic nervous system, as well as cause sodium retention, thus increasing the risk of developing hypertension.
Obesity affects what is known as the renin-angiotensin-aldosterone (RAA) system. The RAA system is responsible for several factors involved in hypertension, including blood volume, control of the sympathetic nervous system, sodium levels, and the amount of water retained by the body.
All these factors have a significant role in blood pressure and since obesity disrupts each of them, the result can be high blood pressure.
