    High blood pressure causes blood to flow through the body at high pressure which can damage organs such as the kidney, heart, and brain, as well as the arteries that circulate the blood. The heart undergoes changes in its shape and size to be able to pump against the higher pressure which can cause heart failure and abnormal heart pumping and filling function. Bleeding can occur in the brain from high blood pressure causing small blood vessels in the brain to rupture. High blood pressure causes pressure injury to the kidneys leading to kidney failure. High blood pressure damages the delicate walls of the body's blood vessels leading to coronary artery disease and heart attack, cerebrovascular disease leading to stroke, and peripheral vascular disease leading to poor blood circulation to the legs.

    High blood pressure can affect your body in several ways. Blood pressure can be elevated when your body increases its volume of blood, when your heart pumps more blood through your arteries and when your arteries are constricted. When it comes to primary high blood pressure the cause of these changes is unclear, but for secondary high blood pressure they may be the result of a kidney disorder, hormonal disorder or a tumor in an adrenal gland. Regardless, they are all partly regulated by your kidneys and it is common for kidneys to get damaged as a result of high blood pressure. The same can be said for your heart and your arteries. The harder they have to work the thicker they get and that's not a good thing. Left untreated, secondary high blood pressure could lead to an aneurysm, stroke or heart attack.

    Hypertension, or high blood pressure, forces the heart and blood vessels to work harder than normal, making them highly susceptible to injury by increasing blood flow that exerts undue pressure and stress against the walls of the blood vessels. Uncontrolled hypertension can lead to an increased risk of serious health conditions, including congestive heart failure, heart attack, stroke, atherosclerosis, brain damage, vision loss, and kidney failure among other things.
  • When your blood moves through your vessels with too much force, you have high blood pressure, or hypertension. Your heart has to work harder when blood pressure is high, and your risk for heart disease and diabetes goes up. High blood pressure raises your risk for heart attack, stroke, eye problems, and kidney disease. High blood pressure is a problem that won't go away without treatment and changes to your diet and lifestyle.
