A condition present when blood flows through the blood vessels with a force greater than normal. Also called high blood pressure. Hypertension can strain the heart, damage blood vessels, and increase the risk of heart attack, stroke, kidney problems, and death.
Causes of High Blood Pressure
High blood pressure, also called “hypertension,” is a serious medical condition. It happens when the force of the blood pumping through your arteries is too strong.
When your heart beats, it pushes blood through your arteries to the rest of your body. When the blood pushes harder against the walls of your arteries, your blood pressure goes up. Your blood pressure may be different at different times of the day. It is usually higher when you first wake up, after you exercise, or when you are under stress.
Having higher blood pressure for short amounts of time is normal. However, when your blood pressure stays high for most of the time, it can cause serious health problems.
One of a pair of organs in the abdomen. The kidneys remove waste and extra water from the blood (as urine) and help keep chemicals (such as sodium, potassium, and calcium) balanced in the body. The kidneys also make hormones that help control blood pressure and stimulate bone marrow to make red blood cells.
