What Is Considered High Blood Pressure For Older Adults
Recent updates to guidelines from the American Heart Association and the American College of Cardiology changed the definition of high blood pressure or hypertension for most people. High blood pressure is now generally defined as 130 or higher for the first number, or 80 or higher for the second number . However, there are important considerations for older adults in deciding whether to start treatment for high blood pressure, including other health conditions and overall fitness. If your blood pressure is above 130/80, your doctor will evaluate your health to determine what treatment is needed to balance risks and benefits in your particular situation.

White Coat And Masked Hypertension
It’s important to distinguish fluctuating blood pressures from two phenomena known as white-coat hypertension and masked hypertension.
In the phenomenon of white coat hypertension, a person’s blood pressure is considered to be “high” at a healthcare provider’s office, but normal when at home. This high blood pressure is attributed to the stress of being in a healthcare provider’s office, which is why a nurse will often wait for a person to rest comfortably for five minutes before taking a read.
In addition, it’s also recommended that two blood pressure reads are taken and repeated if there is a difference of more than 5 millimeters of mercury .
Masked hypertension is the opposite and occurs when healthcare provider’s visit blood pressures are normal but out of the healthcare provider’s office, reads are high.
To sort these issues out, a healthcare provider may recommend home monitoring or ambulatory blood pressure monitoring. Home monitoring may also be recommended for:
- Persistent high blood pressure readings despite increasing medications
- Low blood pressure readings while taking high blood pressure medications

How To Lower Blood Pressure
There are lots of things you can do to lower your blood pressure.
If your doctor has given you blood pressure medication, take it as prescribed. However, you’ll also need to follow a heart-healthy lifestyle.
Even if you haven’t been diagnosed with hypertension, following these tips will be good for your blood pressure and good for your heart.
Quit smoking
Stopping smoking is a great thing you can do for your blood pressure and your heart health.
Ask your doctor or nurse for help.
Phone Quitline 0800 778 778, or visit quit.org.nz for information and support.
Eat more heart-healthy foods and less salt
What you put into your body can make a big difference to your blood pressure.
Eat a wide variety of heart-healthy foods like:
- whole grains

Manage stress
Researchers are still trying to understand the exact link between stress and long-term high blood pressure. However being stressed contributes to other risk factors like poor diet and drinking more alcohol.
You can’t always remove the sources of stress in your life. But here are some things you can do to manage them.
- Enjoy exercise every day, like taking a walk.
- Take a break for yourself.
- Get 7-8 hours plus sleep each night.
- Talk about how you are feeling.
- Try relaxation music or breathing exercises.
Learning To Cope With Stress Can Help
Stress and hypertension have often been linked, but researchers are still looking into a direct relationship between the two. Still, the best advice to hypertensive patients: Try to relax.
When you are stressed, your body sends stress hormones adrenaline and cortisol into the bloodstream. These hormones create a temporary spike in blood pressure, causing your heart to beat faster and blood vessels to narrow. When the stressful situation is over, blood pressure goes back to its normal level.
Chronic stress, however, may cause your body to stay in this highly-charged state longer than natural.
While stress itself may or may not affect blood pressure, how you cope with stress does. For instance, overeating, smoking and drinking alcohol in response to stressful situations are direct causes of sustained high blood pressure. On the flip side, healthier coping mechanisms like exercising, practicing yoga and meditating can all help lower blood pressure.

What Medications Are Used To Treat High Blood Pressure
Four classes of high blood pressure medications are considered first line when starting treatment. Sometimes other medications are coupled with these first-line drugs to better control your high blood pressure. First-line drug pressure lowering medications are:
- Angiotensin-converting enzyme inhibitors block the production the angiotensin II hormone, which the body naturally uses to control blood pressure. When angiotensin II is blocked, your blood vessels dont narrow. Examples: lisinopril , enalapril , captopril .
- Angiotensin II receptor blockers block this same hormone from binding with receptors in the blood vessels. ARBs work the same way as ACE inhibitors to keep blood vessels from narrowing. Examples: metoprolol , valsartan , losartan .
- Calcium channel blockers prevent calcium from entering the muscle cells of your heart and blood vessels, allowing these vessels to relax. Examples: amlodipine , nifedipine , diltiazem .
- Diuretics flush excess sodium from your body, reducing the amount of fluid in your blood. Diuretics are often used with other high blood pressure medicines, sometimes in one combined pill. Examples: indapamide, hydrochlorothiazide, chlorothiazide.

Causes Of Sudden High Blood Pressure
According to the Centers for Disease Control and Prevention, one of out every three American adults suffers from diagnosed high blood pressure with only one half keeping their pressure under control. Sudden high blood pressure usually occurs to a small percentage of people with high blood pressure. This can include young adults, including a high number of African-American men, and those experiencing:
- Collagen vascular disorders
- Pregnancy-induced high blood pressure
Sudden high blood pressure can also be brought on by daily activities and practices.
- Medication use such as over-the-counter pain relievers, a combination of various medications, and abuse of cocaine and marijuana can spike blood pressure levels.
- Smoking can cause a sudden increase in blood pressure as the chemicals, including nicotine, damage the linings of our blood vessels.
- Diet habits are critical to maintaining normal blood pressure levels as the bad fat and sodium found in many foods increase the blood solute content. It also can build up and block the blood vessels, leading to major heart trouble such as a stroke.
- Stress is part of our everyday life and becoming anxious about your worries can increase risk for spikes in blood pressure twofold.
- Medical conditions like kidney disease, spinal injuries, adrenal gland tumors, thyroid issues, and scleroderma can raise blood pressure rapidly.
What Do Blood Pressure Numbers Mean
Blood pressure is measured using two numbers:
The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats.
The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.
If the measurement reads 120 systolic and 80 diastolic, you would say, 120 over 80, or write, 120/80 mmHg.

Have Your Blood Pressure Measured Regularly
Have your blood pressure measured regularly and know what your blood pressure is. Remember that both numbers are important. If either the systolic or diastolic number is high , then your doctor will need to further check your blood pressure. A blood pressure measurement of less than 120/80 mmHg is very good unless it causes dizziness.
What Causes Labile Hypertension
When labile hypertension is suspected, a 24-hour ambulatory blood pressure monitor may be used to confirm the diagnosis. Then the work of pinpointing the underlying cause begins. Serious detective work often is required. We look at the patients overall health, lifestyle and medications, says Dr. Lioudis.
When a medication or lifestyle choice is the precipitating factor, making appropriate changes can cause labile hypertension to disappear.
Underlying medical conditions are a bigger concern, since they may be harder to treat.
We look for sleep apnea, cardiovascular disease, kidney disease or a problem with the adrenal glands, as any of these can cause blood pressure to fluctuate,says Dr. Lioudis.

What Is The Treatment For High Blood Pressure
Mild high blood pressure can often be treated by making lifestyle changes, including:
- losing weight
- limiting your alcohol intake to no more than 2 drinks per day for men, or 1 drink per day for women with high blood pressure
However, lifestyle changes may not be enough. Some people also need medication to help reduce blood pressure levels to normal. While medicines are usually very effective at lowering blood pressure, they may cause side effects in some people.
Usually doctors will start a person on a low dose of a medicine and see how it goes. If it doesnt work well enough, or if there are troublesome side effects, other medicines will be used, sometimes in combination, until the blood pressure is controlled. This can take time. Some people will take medicines for life, although others will find that continuing to lose weight and changing their diet reduces the need for medicines.
Someone whose blood pressure is very high or causing symptoms such as headache, or if they have conditions such as heart disease or diabetes, may need urgent treatment with medicines to bring the blood pressure down to normal levels.
The Royal Australian College of General Practitioners recommends that you regularly review with your doctor or specialist any medications you are taking for high blood pressure or high cholesterol to assess the ongoing benefits and risks.

Excessive Salt Raises Blood Pressure
Too much sodium can cause water retention that puts increased pressure on your heart and blood vessels. People with high blood pressure and those at a high risk for developing hypertension, including adults over 50 and black men and women, should have no more than 1,500 milligrams of sodium daily of salt.
Even people with normal levels should eat salt in moderation. Stick to no more than 2,300 mg of sodium , per day.
Most dietary sodium comes from processed foods. Rules of thumb are to choose foods with 5% or less of the daily value of sodium per serving and opt for fresh poultry, fish and lean meats, rather than canned, smoked or processed. Similarly, fresh or frozen vegetables are better than canned.
A study published in the New England Journal of Medicine found that if people cut just 1/2 teaspoon of salt per day, it could help lower the number of new cases of heart disease per year by up to 120,000.
Further, potassium found in foods like sweet potatoes, spinach, bananas, oranges, low-fat milk and halibut can counterbalance the pressure-increasing effects of sodium by helping to rid the body of excess sodium.

Heart Attack And Heart Disease
High blood pressure can damage your arteries by making them less elastic, which decreases the flow of blood and oxygen to your heart and leads to heart disease. In addition, decreased blood flow to the heart can cause:
- Chest pain, also called angina.
- Heart attack, which happens when the blood supply to your heart is blocked and heart muscle begins to die without enough oxygen. The longer the blood flow is blocked, the greater the damage to the heart.
- Heart failure, a condition that means your heart cant pump enough blood and oxygen to your other organs.
What Is Normal Blood Pressure
A blood pressure reading is written like this: 120/80. It’s read as “120 over 80.” The top number is called the systolic, and bottom number is called the diastolic. The ranges are:
- Normal: Less than 120 over 80
- Elevated: 120-129/less than 80
- Stage 1 high blood pressure: 130-139/80-89
- Stage 2 high blood pressure: 140 and above/90 and above
- Hypertension crisis: higher than 180/higher than 120 — See a doctor right away
If your blood pressure is above the normal range, talk to your doctor about how to lower it.

Blood Pressure Changes And Anxiety
Anxiety is the activation of your fight or flight system a system designed to keep you safe from harm when no danger is present. The fight or flight system causes a number of physical changes that would help you respond to a predator or threat if one was present, but can be distressing when they occur without that danger.
Different types of anxiety can affect your blood pressure in different ways. To understand how anxiety can impact blood pressure, first you must gain a basic understanding of blood pressure and how it fluctuates.
Finally, it is always important to remember that blood pressure fluctuates throughout the day due to exertion, diet, hydration, and more. Blood pressure is not constant even if you do not have any anxiety. So “high blood pressure” may not be high blood pressure at all, and may instead be a reading during one of these fluctuations.
High Blood Pressure During Sleep
Question: What would cause blood pressure to spike extremely high while sleeping? Should one be able to see and feel it when it does this?
Answer: My number one concern from your query is whether we are dealing with obstructive sleep apnea. This common condition, associated with obesity, can cause many problems, including high blood pressure. Normal individuals have a dip in blood pressure during the night. Other individuals have a paradoxical nocturnal rise in blood pressure. Obstructive sleep apnea typically associates with snoring and episodes of disturbed breathing during the night. In addition to a personal history and physical examination, interviewing the patients sleep partner is a first step in diagnosing the condition. A formal sleep study can clinch the diagnosis. Treatment involves weight loss and a breathing device to be worn at night. Treatment of obstructive sleep apnea can help control high blood pressure and can increase alertness during the day, in addition to other health benefits.
Most often, increases in blood pressure do not cause symptoms. This is one of the reasons that this risk factor is so pernicious. An individual can feel perfectly well, yet have high blood pressure that predisposes to cardiovascular events.

What Is Labile Hypertension
Q.I have high blood pressure and have been checking my blood pressure more often since my doctor added another drug. But lately, my readings have been all over the place. For example, one morning it was 127/70, but then it was 170/100 in the late afternoon. Whats going on?
A. You may have a condition known as labile hypertension, which refers to blood pressure that fluctuates far more than usual. Everyones blood pressure rises and falls many times during the course of a single day, sometimes even within minutes. Many factors contribute to these changes, including physical activity, emotion, body position, diet , and sleep deprivation. However, there is no clear definition or standard criteria to distinguish between normal and abnormal fluctuations.

Daily Blood Pressure Pattern
Blood pressure follows a daily pattern. It is normally lower at night while you are sleeping and starts to rise a few hours before you wake up. This rise in BP continues during the day, usually peaking in the middle of the afternoon. By late afternoon or evening, your BP would begin to drop again.
Some people experience abnormality in their BP pattern. One of it is a morning surge in BP , which results in increased risk of damage to the brain, heart and kidneys. Morning hypertension could also happen in those with well-controlled BP.

Why Does Blood Pressure Change
Remember that there are three factors controlling blood pressure at any one time:
- The force and rate of the heart contraction.
- The diameter of the blood vessels throughout the body.
- The volume and even viscosity of the blood.
It is further influenced by hormones, electrolytes and nerve impulses. The activity of all these factors collectively determine blood pressure. The entire system is complex and the body has to cater for changes to keep your body working optimally. Your blood pressure changes when you sit down, stand up or lie flat. It drops when you sleep soundly. It can fluctuate in hot or cold weather.
Here are 6 common reasons for a sudden increase in blood pressure.
