Essential hypertension is high blood pressure that does not have a known cause.
Blood pressure is the force of blood against your artery walls as your heart pumps blood through your body. Hypertension occurs when the force of blood is too strong.
According to the State University of New York’s Upstate Medical University, approximately 95 percent of cases of high blood pressure are essential hypertension (SUNY). The other five percent of hypertension cases are called secondary hypertension. Secondary hypertension is high blood pressure that has an identifiable cause, such as kidney disease.
There is no cure for essential hypertension, but there are treatments.
Blood pressure readings have two numbers, usually written this way: 120/80. The first number is your systolic pressure. Systolic pressure measures the force of blood against your artery walls as the blood is pumped out of your heart to the rest of your body. The second number measures your diastolic pressure. Diastolic pressure measures the force of your blood against your artery walls between heartbeats.
Your blood pressure readings may be temporarily higher or lower throughout the day. They change after exercise, after rest, when you are in pain, and when you are happy or sad. Occasional high blood pressure readings do not necessarily mean you have hypertension. A diagnosis of hypertension is not usually made unless your blood pressure readings are consistently high.
Normal blood pressure is less than 120/80 mmHg.
Prehypertension is higher than normal blood pressure, but not quite high enough to be classified as hypertension. Prehypertension is a systolic pressure of 120 to 139 mmHG or a diastolic pressure of 80 to 89 mmHG.
Stage-1 hypertension is a systolic pressure of 140 to 159 mmHG or a diastolic pressure of 90 to 99 mmHG.
Stage-2 hypertension is higher than 160/90 mmHG.
The higher your blood pressure is, the harder your heart has to work. A stronger force of blood can damage your arteries, blood vessels, and heart muscle. This can eventually cause reduced blood flow through your body, leading to:
Most people do not have symptoms of essential hypertension and only discover that their blood pressure is high during a regular medical checkup. Essential hypertension can begin at any age. It most often occurs first during the middle-age years.
Genetic factors may play a role in essential hypertension. Diet, stress, and being overweight may increase your risks of developing essential hypertension.
Your doctor will test your blood pressure using a blood pressure monitor. If your blood pressure is high, your doctor may want you to check your blood pressure at home during regular intervals. Doing so will help determine if the high blood pressure reading is a common occurrence. Your doctor will teach you how to use a blood pressure monitor if he or she asks you to measure your blood pressure at home. You will record these readings and discuss them with your doctor at a later date.
Your doctor may perform a physical exam to check for signs of heart disease. This exam may include looking at your eyes and listening to your heart. Small blood vessels in the back of your eye can indicate damage from high blood pressure. Damage here indicates similar damage elsewhere.
Your doctor may also order the following tests to detect heart and kidney problems:
If you have prehypertension or hypertension, your doctor will recommend that you start with lifestyle changes to lower your blood pressure. Lifestyle changes your doctor may recommend include:
If lifestyle changes do not lower your blood pressure levels enough, your doctor may prescribe you one or more antihypertensive medications . The most common blood pressure medications include:
You may need to try several different medications until you find a single medicine or a combination of medications that effectively lower your blood pressure. You may need to continue your lifestyle changes and/or take your hypertensive medications for the rest of your life. Some patients are able to use the medication to lower their blood pressure and then maintain that lower pressure with a healthier lifestyle, never needing blood pressure medication again.
According to the National Institutes of Health, there is a good chance your blood pressure can be controlled and your risk of heart attack, stroke, heart failure, eye damage, and kidney damage can be severely reduced or prevented (NIH, 2012). If you already have damage to your heart, eyes, or kidneys, treatment may make the effects of the damage less severe.
