Obesity is a serious risk factor for hypertension, which affects 7 out of 10 obese men, and develops as follows. As the amount of fat tissue in the body increases, the heart is forced to pump more blood around the body in order to meet the extra demand for additional oxygen and nutrients. As this extra blood passes through the arteries, it increases pressure on the arterial walls, leading to higher blood pressure. Hypertension, which is sometimes referred to as "the silent killer", is a significant contributor to cardiovascular disease.
Obesity is also classified as a major risk factor for heart disease, with almost 70 percent of diagnosed cases occurring in obese patients. The prevalence of atherosclerosis (clogging of the arteries) is 10 times higher in obese men compared to those who are not obese. This type of coronary artery disease occurs when fatty deposits build up on the walls of arteries that supply the heart, reducing blood flow and increasing the risk of heart attack.
