The second force is created as the heart rests between heart beatsThink of it this way: In a home where several faucets are open and running, the water pressure flowing out of any one faucet is lower. But when pipes get clogged and there are narrow, the pressure is much greater. And if all the household water is flowing through only one faucet, the pressure is higher still.When the arteries are not as elastic Because of the build-up of cholesterol or plaque or Because of scarring, the heart pumps harder to get blood into the arteries.

They've also identified some factors that Contribute to high blood pressure. These are arteriosclerosis (or hardening of the arteries), Thickening or hypertrophy of the artery wall, and excess contraction of the arterioles (small arteries).In the remaining cases, high blood pressure results from a recognizable underlying problem.

High blood pressure occurs more often in older people-in about three fourth of women and almost two thirds of men aged 75 or older, compared with only about one-fourth of people aged 20 two 74th People who have normal blood pressure at age 55 have a 90% risk of developing high blood pressure. High blood pressure is twice as common among people who are obese as among those who are not.In the United States, only an estimated 70% of people with high blood pressure have been diagnosed. Of people with a diagnosis of high blood pressure, about 84% receive treatment, and of the people receiving treatment, about 58% have adequately controlled blood pressure
