1 billion people worldwide have high blood pressure and this number is expected to increase to 1.56 billion people by the year 2025. This translates to around 1 in 4 adults being afflicted by hypertension as stated by World Hypertension Organizations. Hypertension is prevalent in developing as well as in developed countries.
According to recent estimates of CDC, 67 million Americans have hypertension and half of these do not have it adequately controlled. Nearly 1 in 3 U.S. adults have high blood pressure, but approximately 1/3 of these are undiagnosed due to the asymptomatic nature of hypertension. In fact, many people have high blood pressure for years without knowing it. American Heart Association as well as WHO have reported that Hypertension is long been recognized as a major risk factor for cardiovascular disease.
