Hi. I'm Dr. Leslie Thomas, a nephrologist at Mayo Clinic. In this video, we'll cover the basics of hypertension. What is it? Who gets it? The symptoms, diagnosis, and treatment. Whether you're looking for answers for yourself or someone you love, we're here to give you the best information available. Hypertension means high blood pressure. A blood pressure measurement includes two numbers. Those numbers are the systolic blood pressure and the diastolic blood pressure. Because of the pumping action of the heart, the pressure within the arteries cycles between a higher pressure and a lower pressure. The higher pressure occurs during the contraction of the heart's left ventricle. The higher pressure is known as the systolic blood pressure. The lower pressure occurs during the relaxation of the heart's left ventricle. This lower pressure is referred to as the diastolic blood pressure.

Hypertension is a very common condition affecting up to 40% of adults. It is one of the most common conditions for which medications are prescribed. Most people with hypertension have primary hypertension. How primary hypertension develops is not entirely understood. However, it has felt to result from many inherited and environmental factors that interact in complex ways within the body. Risks for the development of primary hypertension include family history, advancing age, obesity, high sodium diet, alcohol consumption and physical inactivity. In cases of hypertension in which a specific cause is identified, the term secondary hypertension is used. Many potential causes of secondary hypertension exist. These causes include certain prescription or over-the-counter medications, kidney disease, certain endocrine disorders, or a significant narrowing of the aorta or a kidney artery.

Rarely, an individual with very high blood pressure may have symptoms. These symptoms might include shortness of breath, blurry vision or headache.

Hypertension can be diagnosed by performing careful and repeated measures of the blood pressure. Blood pressure categories include normal blood pressure, defined as a systolic pressure less than 120, and a diastolic pressure less than 80. Elevated blood pressure is defined as a systolic pressure 120 to 129, and a diastolic pressure less than 80. Hypertension is defined as systolic pressure greater than or equal to 130, or a diastolic pressure greater than or equal to 80.

Treatment of hypertension involves lifestyle modification alone or in combination with antihypertensive medication therapy. For individuals with certain common conditions, including cardiovascular disease, chronic kidney disease, and diabetes mellitus. Certain medications may be more advantageous to use compared to other medications. Deciding upon the best blood pressure to target, when to start antihypertensive medication therapy, and which specific medication or a combination of medications to utilize is highly individualized and informed by many factors.

You and your care team can work together to create the best treatment plan for you. No matter what methods you decide on. There are plenty of reasons to be optimistic about managing your hypertension. If you'd like to learn even more about hypertension, watch our other related videos or visit mayoclinic.org. We wish you well.

High blood pressure is a common condition that affects the body's arteries. It's also called hypertension. If you have high blood pressure, the force of the blood pushing against the artery walls is consistently too high. The heart has to work harder to pump blood.

Blood pressure is measured in millimeters of mercury (mm Hg). In general, hypertension is a blood pressure reading of 130/80 mm Hg or higher.

The American College of Cardiology and the American Heart Association divide blood pressure into four general categories. Ideal blood pressure is categorized as normal.)

• Normal blood pressure. Blood pressure is 120/80 mm Hg or lower.
• Elevated blood pressure. The top number ranges from 120 to 129 mm Hg and the bottom number is below, not above, 80 mm Hg.
• Stage 1 hypertension. The top number ranges from 130 to 139 mm Hg or the bottom number is between 80 and 89 mm Hg.
• Stage 2 hypertension. The top number is 140 mm Hg or higher or the bottom number is 90 mm Hg or higher.

Blood pressure higher than 180/120 mm Hg is considered a hypertensive emergency or crisis. Seek emergency medical help for anyone with these blood pressure numbers.

Untreated, high blood pressure increases the risk of heart attack, stroke and other serious health problems. It's important to have your blood pressure checked at least every two years starting at age 18. Some people need more-frequent checks.

Healthy lifestyle habits —such as not smoking, exercising and eating well — can help prevent and treat high blood pressure. Some people need medicine to treat high blood pressure.

Symptoms

Most people with high blood pressure have no symptoms, even if blood pressure readings reach dangerously high levels. You can have high blood pressure for years without any symptoms.

A few people with high blood pressure may have:

• Headaches
• Shortness of breath
• Nosebleeds

However, these symptoms aren't specific. They usually don't occur until high blood pressure has reached a severe or life-threatening stage.

When to see a doctor

Blood pressure screening is an important part of general health care. How often you should get your blood pressure checked depends on your age and overall health.

Ask your provider for a blood pressure reading at least every two years starting at age 18. If you're age 40 or older, or you're 18 to 39 with a high risk of high blood pressure, ask for a blood pressure check every year.

Your care provider will likely recommend more-frequent readings if have high blood pressure or other risk factors for heart disease.

Children age 3 and older may have blood pressure measured as a part of their yearly checkups.

If you don't regularly see a care provider, you may be able to get a free blood pressure screening at a health resource fair or other locations in your community. Free blood pressure machines are also available in some stores and pharmacies. The accuracy of these machines depends on several things, such as a correct cuff size and proper use of the machines. Ask your health care provider for advice on using public blood pressure machines.
