High blood pressure is twice as likely to strike a person with diabetes than a person without diabetes. Left untreated, high blood pressure can lead to increased risk for heart disease and stroke. In fact, a person with diabetes and high blood pressure is four times as likely to develop heart disease than someone who does not have either of the conditions. About 73 percent of adults with diabetes have blood pressure greater than or equal to 130/80 mm Hg or use prescription medications for hypertension.

What is high blood pressure?

Blood pressure is the force of the blood pushing against the artery walls. Each time the heart beats, it is pumping blood into these arteries, resulting in the highest blood pressure when the heart contracts and is pumping the blood. High blood pressure, or hypertension, directly increases the risk of coronary heart disease (heart attack) and stroke (brain attack). With high blood pressure, the arteries may have an increased resistance against the flow of blood, causing the heart to pump harder to circulate the blood.

Two numbers are used to measure blood pressure. The higher number, the systolic pressure, refers to the pressure inside the artery when the heart contracts and is pumping the blood through the body. The lower number, the diastolic pressure, refers to the pressure inside the artery when the heart is at rest and is filling with blood. Both the systolic and diastolic pressures are recorded as "mm Hg" (millimeters of mercury). This recording represents how high the mercury column is raised by the pressure of your blood.

According to the National Heart, Lung, and Blood Institute of the National Institutes of Health, high blood pressure for adults is defined as:

In an update of NHLBI guidelines for hypertension in 2003, a new blood pressure category was added called prehypertension:

The new NHLBI guidelines now define normal blood pressure as follows:

What are the symptoms of high blood pressure?

Often, persons with high blood pressure do not have noticeable symptoms. If the blood pressure is greatly elevated, an individual may experience the following. However, each individual may experience symptoms differently. Symptoms may include:

The symptoms of high blood pressure may resemble other medical conditions or problems. Always consult your doctor for a diagnosis.
