When a person has high blood pressure, doctors often focus on the systolic number, but the diastolic number can, and often does, elevate as blood pressure increases. High blood pressure is a serious, often symptomless condition that a person should take steps to decrease. Lifestyle changes such as reaching or maintaining a moderate weight and exercising regularly can help. A person should talk to their doctor if their blood pressure does not decrease in response to them making healthful lifestyle changes.

Elevated Elevated blood pressure is when readings consistently range from systolic and less than 80 mm Hg diastolic. Hypertension Stage 1 Hypertension Stage 1 is when blood pressure consistently ranges from systolic or mm Hg diastolic. Hypertensive crisis This stage of high blood pressure requires medical attention. Your blood pressure numbers and what they mean Your blood pressure is recorded as two numbers: Systolic blood pressure the first number — indicates how much pressure your blood is exerting against your artery walls when the heart beats.
Diastolic blood pressure the second number — indicates how much pressure your blood is exerting against your artery walls while the heart is resting between beats. Which number is more important? Why blood pressure is measured in mm Hg The abbreviation mm Hg means millimeters of mercury.
Taking your pulse versus checking your blood pressure While both are indications of health, blood pressure and heart rate pulse are two separate measurements.

Blood pressure — particularly systolic blood pressure — naturally tends to increase with age. Because of this, there may be no identifiable cause for high blood pressure.
However, there are some medical conditions that can cause someone to develop ISH. These conditions often have effects on the circulatory system, which can damage blood vessels or contribute to artery stiffening.
Some of these conditions include:. There are many types of anemia, but iron deficiency anemia is the most common. Damage can be caused to your blood vessels as your heart works harder to pump blood to the tissues of your body in order to deliver sufficient oxygen.
Diabetes happens when the amount of glucose in your blood is too high. Insulin normally controls blood glucose levels. Over time, high glucose levels in your blood can lead to a variety of problems, including those with the heart and circulatory system.
Hyperthyroidism , or overactive thyroid, occurs when your thyroid gland produces more thyroid hormones than necessary. This surplus of thyroid hormone can affect almost every organ in your body, including your heart and circulatory system. Because blood oxygen levels can drop when breathing stops, obstructive sleep apnea can strain your cardiovascular system and lead to increases in blood pressure. When high blood pressure is left uncontrolled, it can cause damage to your arteries.
This can affect various parts of your body and can increase your risk for the following conditions:. A blood pressure reading consists of two numbers — your systolic blood pressure and your diastolic blood pressure.
But what do these numbers actually mean? The first number is your systolic blood pressure. The second number is your diastolic blood pressure.
There are several different blood pressure categories, which are currently defined as the following:. ISH is when you have a systolic blood pressure reading of mm Hg or higher, and a diastolic blood pressure reading of less than 90 mm Hg. ISH can be treated like other forms of hypertension. The goal is to reduce your systolic blood pressure to below mm Hg. This can be accomplished through implementation of lifestyle changes, through medication, or both.
Lower-than-normal diastolic blood pressure may lead to heart damage. A review of studies in elderly adults with ISH has found that the following medications had the greatest efficacy in reducing risk of stroke and other cardiovascular events. The following drugs were found to have less efficacy, however they may still be effective in treating ISH.
You may also need to make some lifestyle changes as part of your ISH treatment plan.
