What is Considered a High Diastolic Blood Pressure?
Your blood pressure reading will always be shown as two numbers together, such as 120/80. The second number is the diastolic reading. If your lower number rises between 80 and 89, you are considered to have borderline high diastolic blood pressure, or pre-hypertension. If your number goes up above 90, it is considered to be a high diastolic blood pressure, and may require treatment to bring the number back down. On the other hand, a top number of 130-139 is considered borderline high, and a number over 140 is high. In most cases, when the systolic pressure rises, there will be a high diastolic blood pressure as well. However, there are some instances where the systolic pressure will rise on its own, while the diastolic number remains normal. This is called isolated systolic high blood pressure, and is generally seen in elderly patients. If you have a high diastolic blood pressure, you will need to take steps to bring your blood pressure back down to a normal level, to reduce your risk
