How Is Blood Pressure Measured
Health care providers measure blood pressure with a cuff that wraps around the upper arm. When the cuff inflates, it squeezes a large artery, stopping the blood flow for a moment. Blood pressure is measured as air is slowly let out of the cuff, which lets blood flow through the artery again.
Blood pressure is measured in two numbers:
You hear blood pressure reported as the first number “over” the second number, like 120 over 80 or 120/80.
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. What’s going on?
A. You may have a condition known as labile hypertension, which refers to blood pressure that fluctuates far more than usual. Everyone’s 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.

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.

Why Does My Blood Pressure Go Up When I Go To The Doctor
Cause of Temporary High Blood Pressure: Doctors freak you out. If you get nervous the second you step into your doctors office, your heart might start pounding. The body essentially reacts in a fight-or-flight manner, increasing the heart rate and getting ready to make a move, says Dr. Kaplan.
Blood pressure is normally lower at night while youre sleeping. Your blood pressure starts to rise a few hours before you wake up. Your blood pressure continues to rise during the day, usually peaking in the middle of the afternoon.

How Is High Blood Pressure Diagnosed
A single reading showing high blood pressure doesn’t mean that you have hypertension. Sometimes, blood pressure needs to be checked several times over a period of days or weeks to know if someone has hypertension. Your doctor will probably weigh and measure you. He or she might do urine tests or blood tests to check for other conditions that can cause hypertension.
Some people have what’s called “white coat hypertension.” This means that their blood pressure goes up when they’re at a doctor’s office because they’re nervous. When they feel more relaxed, their blood pressure usually goes down. To make sure high blood pressure readings aren’t caused by anxiety, doctors will sometimes track a person’s blood pressure over a whole day. This is called ambulatory blood pressure monitoring.
Blood Pressure Lying Down Vs Sitting
Many wonder why positioning makes such a difference in blood pressure readings. Lets take lying down vs. sitting as an example. Our heart is a pump, and it takes less work to pump blood to our brain when we are lying down. This is because our head is about the same level as our heart. However, when we are up, our head is a lot higher than our heart. This means the heart has to pump much harder to get blood to our brain, so as a result, blood pressure is higher.
In most cases, blood pressure is taken while a person is sitting down with the arm dropping onto a table. While sometimes the middle point of the upper arm might, in fact, be parallel and in line with the position of the heart, the rest of the arm is not, so it should not be surprising that the measurement taking while laying down might be a little lower, since there is less gravity to counter.

High Blood Pressure Treatment
The best way to lower blood pressure begins with changes you can make to your lifestyle to help lower your blood pressure and reduce your risk of heart disease. Additionally, your doctor may prescribe medicine to lower your blood pressure. These are called antihypertensive medicines.
The goal of treatment is to reduce your blood pressure to normal levels. Your doctor may prescribe medicine thats easy to take and has few, if any, side effects. This treatment is highly successful. If your blood pressure can only be controlled with medicine, youll need to take the medicine for the rest of your life. It is common to need more than one medicine to help control your blood pressure. Dont stop taking the medicine without talking with your doctor. Otherwise, you may increase your risk of having a stroke or heart attack.
What Are The Symptoms Of Resistant Hypertension
You can have hypertension without having any symptoms. The best way to know if you have high blood pressure is to have your blood pressure checked by a health care provider.
However, symptoms may be felt when blood pressure first rises or during a hypertensive crisis, when levels are extremely high. These symptoms may include headaches, shortness of breath, chest pain and nosebleeds.
Dizziness is usually not a symptom of high blood pressure. In fact, dizziness can sometimes be a symptom of low blood pressure. Frequent or unexplained dizziness may be a warning sign of a serious condition and should be addressed by your physician.

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.
Preventing High Blood Pressure
You may head off blood pressure problems before they start, or limit your risk, if you follow a healthy lifestyle. Following the steps listed above under Treating high or low blood pressure can help protect you from developing high blood pressure.
In addition, if you suspect you have sleep apnea symptoms, such as heavy snoring, daytime sleepiness, or restless sleep, talk to your doctor about a sleep study. Sleep apnea is believed to affect at least 25 million American adults. has shown that using a CPAP machine while sleeping can reduce blood pressure in people with sleep apnea.

What Causes Your Blood Pressure To Suddenly Get High
Hypertension or high blood pressure is a medical condition where the pressure in the arteries is persistently elevated. The heart pumps blood into the arteries, and it is circulated to all parts of the body. Hypertension develops when the heart constantly needs to exert higher force to deliver the blood to the organs through the arteries. Since a hypertensive heart must work harder to deliver blood, hypertension can increase the risk of cardiovascular disease, heart attack and heart failure. Also, the blood vessels in people with hypertension are narrower, putting them at risk of stroke, kidney disease and vision loss.
There are many reasons for high blood pressure. Some possible causes include caffeine, acute stress or anxiety, certain medications , combinations of medications, recreational drugs, sudden or acute pain, dehydration and white coat effect .
What To Know About Blood Pressure Changes When You Move From One Position To Another
Your blood pressure can also change as you move from one position to another. This may be particularly noticeable when you move from a sitting or lying position to a standing position.
When you stand, gravity causes blood to pool in your lower body. This can cause a temporary drop in blood pressure. However, your body has a way to adjust to this change.
Certain reflexes in your body send a signal to your brain when a drop in blood pressure is detected. Your brain then tells your heart to beat faster in order to pump more blood. This works to stabilize your blood pressure.
However, sometimes this process can be interrupted, causing the drop in blood pressure to last longer than normal. When this happens, theres a delay in blood flow to your brain. As a result, you may feel lightheaded, dizzy, or faint for a short while after you stand.
This condition is called orthostatic hypotension or postural hypotension. It can be caused by a variety of factors, including:

Good Sleep Can Prevent And Manage High Blood Pressure
Most people experience a dip in blood pressure during the deepest stage of sleep , which is the body’s normal and healthy reaction to sleep. Not having that nighttime dip is a risk factor for heart disease and may increase daytime blood pressure.
Typically people spend 90 minutes to two hours in slow wave sleep per night. A recent study published in Hypertension found that men who got less slow wave sleep each night were a higher risk for hypertension than men who got more deep sleep.
While sleep disorders, like sleep apnea, and age can both affect the amount of deep sleep you get, there are steps you can take to ensure a good night’s sleep. Getting seven to eight hours of sleep a night, maintaining a consistent sleep schedule and being more active during the day can help improve the quality of your sleep.

Treatments For Sudden Rise In Blood Pressure
A rise in already high blood pressure requires immediate medical attention. You can expect to have intravenous therapy and tests to determine what caused the spike in your pressure. Once your pressure is stabilized to a satisfactory level, then your doctor will discuss further treatment. Depending on your current health condition and any issues aside from high blood pressure, your treatment will vary.For example, if there is fluid in your lungs, you will be treated with prescribed diuretics to remove the fluid. If there is damage to your heart, you will be prescribed specific heart medication. Medications you may be taking may need to be adjusted or changed to another type, depending on your test results. Any kidney damage or tumors may require surgery.

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.
