Essential Hypertension

Hypertension essentials from Lark Health


Is your blood pressure high? It may well be, since 1 in 3 Americans have hypertension, and another 1 in 3 have pre-hypertension, or slightly elevated blood pressure. 

Blood pressure is a measurement of the force of the blood against your blood vessels. Pre-hypertension and hypertension occur when that force is higher than normal.

Most of hypertension is essential, or primary, hypertension. That is, their hypertension is not caused by another condition.

 

High Blood Pressure Numbers


When you get your blood pressure measured, you will usually see two numbers, expressed as a fraction. The higher number is the systolic blood pressure, or the force of blood when your heart is contracting. The bottom number, which is lower, is your diastolic blood pressure. This is your blood pressure when your heart is relaxed between beats.

These are the American Heart Association’s (AHA’s) cut-offs for normal and elevated blood pressure.

Blood Pressure Category Systolic Blood Pressure (SBP) Diastolic Blood Pressure (DBP)
Normal
<120 mm Hg
and
<80 mm Hg
Elevated
120–129 mm Hg
and
<80 mm Hg
Hypertension Stage 1
130–139 mm Hg
or
80–89 mm Hg
Hypertension Stage 2
≥ 140 mm Hg
or
≥ 90 mm Hg

The only way to know if you have high blood pressure is to get your blood pressure measured. Your doctor probably does it at most, if not all, of your appointments. At a minimum, get your blood pressure checked every two years if you are under 40 years old and have no risk factors. If you have risk factors or are over 40 years old, check your blood pressure every year. Many pharmacies and drug stores, and many supermarkets with pharmacies, have blood pressure machines that you can use.

 

Hypertension Risk Factors


Some people are naturally at higher risk for hypertension. People of African American descent and individuals with a family history of high blood pressure are at higher risk. Your risk increases as you get older. Diabetes, kidney disease, and sleep apnea raise your risk as well.

There are many risk factors that you can control. Your risk increases if you:

  • Are overweight or obese.

  • Are not physically active.

  • Eat a high-sodium (high-salt) and/or low-potassium diet.

  • Smoke or use other tobacco products.

  • Drink alcohol in excess, such as more than one (women) or two (men) drinks per day.

  • Have a lot of stress and are unable to manage it.

Healthy lifestyle choices can lower your risk for high blood pressure.

 

Essential Hypertension Symptoms and Complications


Symptoms of hypertension are rare. You can have high blood pressure for years without knowing that you have it. Some people do not find out that they have hypertension until they have a hypertension-related event, such as a stroke or a heart attack. That is why it is important to get your blood pressure checked regularly. 

Some people may have symptoms such as:

These symptoms are rare and can indicate other problems, so it is best to measure your blood pressure if you have these symptoms or if you have no symptoms.

Uncontrolled hypertension can lead to serious complications. The majority of people who have a heart attack or stroke have high blood pressure. Other complications can include kidney disease, trouble with vision, aneurysm, and difficulty remembering things.

 

Hypertension Treatment


Only about half of people with hypertension have their blood pressure under control, but in most cases, you can lower your blood pressure simply by following doctor’s orders, such as taking your blood pressure medications as prescribed. 

Many people do not take their hypertension medications exactly as prescribed. They may skip doses or take the wrong dose sometimes. They may not realize how important it is to take every single dose as prescribed, or they may forget to take a dose here or there.

Lark Hypertension Care can help you improve your blood pressure control by helping you be more compliant with your prescription medications. Lark can:

  • Send you push notifications to remind you to take your dose.

  • Discuss your past week’s medication adherence trends to motivate you to keep taking your meds.

  • Let you know how the medications work and why they are so important for blood pressure control.

Along with taking your medications, you can stay on top of blood pressure by monitoring it at home if your doctor suggests it. Again, Lark can remind you to take it, and when your blood pressure machine syncs automatically with Lark, Lark can help you see your trends. This can help you link health behaviors to blood pressure control so you can see what works and stay motivated to take your medications and make other healthy choices.

 

Best Hypertension Diet


What you eat can have a surprisingly large impact on your blood pressure. For example, one study found a decrease in systolic blood pressure of 11 mm Hg when participants followed an eating pattern called Dietary Approaches to Stop Hypertension (DASH). The pattern is high in vegetables, fruit, reduced-fat dairy products, and whole grains, and low in fatty meats and sugary foods. 

The best hypertension diet provides blood pressure-lowering nutrients such as calcium and potassium and is low in blood pressure-raising nutrients such as sodium. A good hypertension diet also helps with weight control, since excess pounds raise blood pressure.

More Ways to Lower Blood Pressure Naturally


Other healthy lifestyle choices can have major effects on your blood pressure. Consider physical activity, for example. Getting in 90 to 150 minutes per week of aerobic activity at a moderate to vigorous intensity can lead to a decrease in systolic blood pressure of 5 to 8 mm Hg. Lark can remind you to get active and track your activity. You might try:

  • Walking briskly or uphill

  • Hiking

  • Swimming

  • Dancing

  • Bicycling

  • Gardening

  • Skiing

  • Rowing

  • Playing a sport

Contrary to what many people think, strength training can also lower blood pressure by as much as 5 mm Hg. You can lift weights, do body weight exercises, or try other equipment such as kettlebells, resistance bands, and medicine balls.

Other ways to lower blood pressure naturally are:

  • Get adequate sleep.

  • Manage stress.

  • Quit smoking or using tobacco.
