High Blood Pressure/Hypertension

High Blood Pressure/Hypertension: Introduction

High blood pressure, also known as hypertension, is a very common and serious condition that can lead to and/or complicate many health problems, including coronary heart disease, stroke, kidney failure and heart failure. About one in three adults in the U.S. have high blood pressure/hypertension, according to the National Heart, Lung and Blood Institute.

Blood pressure is defined as the pressure that is put on the walls of the arteries as blood is pumped through the circulatory system. Blood pressure is measured as a two numbers (i.e. 120/80nnHg) but it is not a fixed number. Normally, blood pressure rises and falls as a response to many situations. For example, blood pressure will rise during strenuous activity in order to ensure that all the cells of the body get additional amounts of oxygen-rich blood. Blood pressure may also rise in response to stressful situations, and it is normally lower during periods of relaxation or sleep. It is the cumulative effects of blood pressure that is stays too high that results in serious complications.

There are three general types of high blood pressure/hypertension. Essential hypertension occurs when the condition has no known cause. When high blood pressure/hypertension is caused by another condition or disease process, it is called secondary hypertension. When only the systolic blood pressure number (the top number) is high, it is called isolated systolic hypertension, which is common in older adults.

High blood pressure/hypertension has a variety of causes. It generally tends to rise with age. It can also be caused by other medical conditions, such as thyroid disease or chronic kidney disease. It may also be a side effect of certain medications, such as over-the-counter cold medications and oral contraceptives ("the Pill") and other hormone drugs. Obesity and heredity also play a role in the development of high blood pressure/hypertension.

High blood pressure/hypertension is often called "the silent killer" because it generally has no symptoms until serious complications develop. When symptoms do occur, they can differ between individuals depending on such factors as the level of high blood pressure/hypertension, age, underlying cause, medical history, the presence of complications and general health. For more information on symptoms and complications, refer to symptoms of high blood pressure/hypertension.

Making a diagnosis of high blood pressure/hypertension includes performing a complete evaluation that includes a medical history and physical examination and blood pressure readings.

Blood pressure is measured using two numbers, (i.e.120/80mmHg). The "top" number is called the systolic number, which is a measurement of the pressure on the artery walls when the heart beats. The "bottom" number is the diastolic number, which is a measurement of the pressure on the artery walls when the heart is resting between beats.

Many people think of a reading of 120/80mmHg as "normal". In fact there are many variations of normal that are dependent on a variety of factors. Unless a blood pressure reading is very high and needs to be addressed immediately, blood pressure readings will be monitored over period of time to assess for trends and to get an idea of an individual's overall blood pressure.

As a very general guide, adults should keep their blood pressure below 140/90mmHg. In addition, current guidelines consider consistent readings over 120/80mmHg as a condition called pre-hypertension, which should be monitored and addressed to ensure that blood pressure does not rise higher over time.

It is very possible that a diagnosis of high blood pressure/hypertension can be missed or delayed because there are generally no symptoms in the early stages. For more information on misdiagnosis, refer to misdiagnosis of high blood pressure/hypertension.

Patient compliance with a good treatment plan generally results in a normalization of blood pressure and also minimizes complications. For more information on treatment, refer to treatment of high blood pressure/hypertension. ...more »
