Everything you need to know about hypertension Hypertension or high blood pressure can lead to heart disease, stroke, and death and is a major global health concern. A range of risk factors may increase the chances of a person developing hypertension, but can it be prevented? Read on to find out what causes hypertension, its symptoms, types, and how to prevent it. Read now
While the words “blood pressure-lowering diet” may conjure images of unseasoned egg whites and limp steamed veggies, getting your blood pressure into a healthy range is more than just doable —it can be downright delicious. Start by adding the Eat This, Not That!-approved list of blood pressure-lowering foods into your regular routine and watch your numbers go from scary to stellar in no time.
A recent study compared diuretics with other types of blood pressure-lowering medications and found the diuretics were just as effective as the newer drugs in preventing heart attack or death due to heart disease. The new guidelines say these inexpensive drugs should be used as first-line treatment for most people who have high blood pressure without other risk factors such as heart failure, history of heart attack, diabetes, or kidney disease.
In “guessing” on the best initial single drug to try, most experts now recommend beginning either with either a thiazide diuretic (usually chlorthalidone or hydrochlorothiazide), a long-acting calcium blocker, or an ACE inhibitor. ARBs are generally thought of as substitutes for ACE inhibitors, and generally, are used only when ACE inhibitors are poorly tolerated.
Take your medicines and monitor your blood pressure. Take the medications prescribed for you regularly and don’t stop them except on the advice of your health care provider. Hypertension tends to worsen with age and you cannot tell if you have high blood pressure by the way you feel, so have your health care provider measure your blood pressure periodically. You may also want to buy a home blood pressure monitor, available in many drug stores, to measure your blood pressure more frequently. Your health care provider or pharmacist can help you choose the right device. Many drug stores also have blood pressure measuring devices you can use in the store.
Although the guidelines do not change the traditional definition of high blood pressure, they do call for more aggressive treatment of the condition through the use of a combination of blood-pressure lowering medications. In fact, they say that most people with high blood pressure will require two or more drugs to achieve a blood pressure goal of less than 140/90. The blood pressure goal in people with diabetes or kidney disease should be less than 130/80.
As mentioned earlier, blood pressure increases with age, beginning from infancy to older adulthood. Since most healthy babies and children are typically not at risk for blood pressure problems, most doctors do not check their blood pressure routinely. But, the normal BP range for all adults, regardless of their age, is considered to be lesser than 120/80.
While high blood pressure doesn’t have any distinctive symptoms in itself, there can be many associated conditions and signs that high blood pressure may be affecting your body and causing damage. When left untreated, high blood pressure can cause the following symptoms in the body, which may worsen over time. If you are experiencing any of the following symptoms chances are your high blood pressure may be placing you at risk of developing further conditions and should be addressed immediately.
She'll inflate the cuff to a pressure higher than your systolic blood pressure, and it will tighten around your arm. Then she'll release it. As the cuff deflates, the first sound she hears through the stethoscope is the systolic blood pressure. It sounds like a whooshing noise. The point where this noise goes away marks the diastolic blood pressure.
But it’s not all bad news. Yes, hypertension contributes to a lot of serious conditions, but blood pressure treatment options are very effective. And the first step, of course, is knowing if you have high blood pressure. You can check your blood pressure for free at many pharmacies nationwide. CVS “Minute Clinics” and Walgreens Blood Pressure screening both offer in-store blood pressure test.
This headache isn't the kind that you pop some over-the-counter meds and it goes away. If you're getting severe headaches with no prior history of migraines, high blood pressure may be to blame. Extremely high blood pressure, known as malignant hypertension, puts pressure in the cranium (the part of the skull that encloses the brain). As blood pressure rises, pain builds in the cranium. That causes severe headaches.
Chances are, if you're in your twenties or thirties, joint health doesn't even hit the top 100 of your priorities. However, most people in their forties or fifties start experiencing some joint issues, and it doesn't happen overnight. Nature needs us to succeed and thrive until we produce offspring, so for a while our bodies forgive our poor lifestyle choices, the lack of nutrients and the excess of toxic compounds and function relatively well.
The causes are most often some combination of clogged “pipes” and excessive salt in the diet. Lifestyle changes, such as appropriate diet and exercise, are among the most effective treatment strategies for high blood pressure. Relaxation, meditation, and otherwise “taking it easy” are not effective solutions, as valuable as such strategies may be for your psychological well-being.
Alpha methyldopa (Aldomet)* may produce a greater drop in blood pressure when you're in an upright position (standing or walking), and it may make you feel weak or faint if the pressure has been lowered too far. This drug may also cause drowsiness or sluggishness, dryness of the mouth, fever or anemia. Male patients may experience impotence. If this side effect persists, your doctor may have to change the drug dosage or use another medication.
Many of us have had our blood pressure measured at the doctor but don’t really understand why it’s important. Find out why (and how) your doctor measures your blood pressure, what’s normal and what’s not, and what to do if you have high blood pressure.How is blood pressure measured?Blood pressure is measured using an instrument called a sphygmomanometer. It consists of an inflatable cuff, an inflating bulb, and a gauge to show the blood pressure.The cuff is wrapped around the upper arm, and inflated to a pressure which temporarily stops the blood from flowing through the brachial artery – the main blood vessel in your arm. At this point, the doctor will not be able to feel a pulse in the arm. The cuff pressure is then raised slightly above this point, and then slowly lowered.As the pressure is lowered, your doctor will listen through a stethoscope for the sound of blood starting to pulse through the brachial artery again. The pressure reading on the sphygmomanometer when the sound of blood is first heard pulsing through the artery is known as the systolic pressure. As the doctor continues to lower the pressure in the cuff, the sounds will disappear. Usually, the point at which the sounds disappear is known as the diastolic pressure.The systolic reading (the first number of the 2) indicates the pressure of blood within your arteries during a contraction of the left ventricle of the heart. The diastolic reading (the second number) indicates the pressure within the arteries when the heart is at rest. Blood pressure is measured in millimetres of mercury (mmHg), for example 120/80 mmHg (known as 120 over 80).What is normal blood pressure?According to the Heart Foundation of Australia, as a general guide:blood pressure below 120/80 mmHg can be classified as 'optimal';blood pressure between 120/80 and 129/84 mmHg is 'normal'; andblood pressure between 130/85 and 139/89 mmHg is classified as 'high-normal'.A person is defined by the Heart Foundation as having high blood pressure (hypertension) if they:have a systolic pressure greater than or equal to 140 mmHg; and/ora diastolic pressure greater than or equal to 90 mmHg.High blood pressure is further classified as mild, moderate or severe as the pressure increases above this level.Low blood pressure, or hypotension, is not as easy to define as it is usually relative to a person’s normal blood pressure reading, and varies between different people. It generally refers to a blood pressure below an average of about 90/60 mmHg.Getting an accurate readingAccording to the Heart Foundation, the diagnosis of high blood pressure should be based on multiple blood pressure measurements taken on separate occasions.It is recommended that you do not smoke or drink caffeine-containing drinks for 2 hours before having your blood pressure monitored, as this can cause an increase in your readings.Self-monitoring of blood pressure in your own environment (home blood pressure monitoring) or ambulatory monitoring of blood pressure is also used to help diagnose high blood pressure.For ambulatory blood pressure monitoring, you wear a portable automatic blood pressure machine for 24 hours while going about your usual daily routine. The portable monitor will measure your blood pressure multiple times during the 24 hours. Your doctor will ask you to record your activities over the 24 hours, plus any symptoms you experience (and when they occur). Variations in blood pressure are normal and may occur depending on where and when the blood pressure is taken.Some people who have raised blood pressure readings taken at the doctor’s surgery actually have acceptable levels outside the surgery, when under normal stress levels. This is known as ‘white-coat’ hypertension.There are also people with ‘reverse white-coat’ hypertension (also known as masked hypertension), who have normal blood pressure when measured in the clinic but high ambulatory blood pressure readings (those recorded during normal daily activities).Keeping on targetYour target blood pressure may vary according to whether you have other conditions that can increase your risk of cardiovascular (heart and blood vessel) disease or conditions that have been caused by high blood pressure.Raised blood pressure is a major risk factor for cardiovascular disease, and the higher your blood pressure, the greater your chance of having heart disease or stroke. For this reason it is important that you have your blood pressure monitored regularly, and that you always take any high blood pressure treatments that have been recommended, including medicines that have been prescribed.Hypertension can also be controlled to a large extent by lifestyle measures such as:losing excess weight;undertaking regular physical activity;quitting smoking; andchanging your diet (reducing your alcohol and salt intake, and following a healthy eating plan).These steps can help to lower your blood pressure and reduce your risk of cardiovascular disease.

Health care providers measure blood pressure with a sphygmomanometer (sfig-mo-muh-NAH-muh-ter), which has a cuff that's wrapped around the upper arm and pumped up to create pressure. When the cuff is inflated, it squeezes a large artery in the arm, stopping the blood flow for a moment. Blood pressure is measured as air is gradually let out of the cuff, which allows blood to flow through the artery again.
Be proactive and follow all medical advice received about how to manage hypertension. It is crucial to continue on any prescriptions given to treat hypertension. It is very dangerous to stop taking a medication for hypertension just because the symptoms seem to have lessened. Have frequent medical checkups and stay in touch with the doctor if any new symptoms arise.

Magnesium: Magnesium, which is present in nuts, seeds, avocado, and green leafy vegetables, has also been proposed as a natural way to reduce blood pressure. Supplements are also available in pill form. Studies show that higher levels of magnesium are associated with lower blood pressure, but it is still not completely clear whether there is a cause-and-effect relationship.
The reasons for this astonishing success are not yet entirely understood. Certainly, two of the major causes of high blood pressure are being addressed: excessive dietary salt is completely eliminated, and it is likely that some patients experience some reversal of the atherosclerosis process. However, Dr. Campbell has suggested that additional mechanisms may be partly responsible for fasting’s remarkable effects, such as the rapid reduction of a phenomenon known as “insulin resistance.”
The new guidelines stem from the 2017 results of the Systolic Blood Pressure Intervention Trial (SPRINT), which studied more than 9,000 adults ages 50 and older who had systolic blood pressure (the top number in a reading) of 130 mm Hg or higher and at least one risk factor for cardiovascular disease. The study's aim was to find out whether treating blood pressure to lower the systolic number to 120 mm Hg or less was superior to the standard target of 140 mm Hg or less. The results found that targeting a systolic pressure of no more than 120 mm Hg reduced the chance of heart attacks, heart failure, or stroke over a three-year period.
Hypertension in African-Americans tends to occur earlier in life and tends to be more severe. Plus, some medications that work to lower blood pressure in other ethnicities may have limited effect on African-Americans. Thiazide diuretics (such as HCTZ) or a calcium channel blocker are recommended first choices along with the possible add-on of a second drug from either the ACE inhibitor class or the angiotensin II receptor blocker group.
For example, in a hypertensive patient with asthma, it may be inadvisable to prescribe a beta blocker, as these drugs can aggravate that respiratory condition. Similarly, in patients prone to constipation (the elderly, for example) use of certain calcium channel blockers might best be avoided -- along with diuretics -- as both these classes of drugs can inhibit proper bowel function.
How do you check your own blood pressure? It is common to have your blood pressure checked at the doctor's office, but there are many cases where it is important to monitor it at home. It is easy to check blood pressure with an automated machine, but it can also be done manually at home. Learn how to check your own blood pressure and what the results mean. Read now
Up to 40% of patients taking clonidine (Catapres) will experience dry mouth and about a third will have drowsiness, headache, and sleepiness. Other common side effects include constipation, dizziness, and local skin reactions with use of the Catapres-TTS skin patch. Reserpine use is linked with possible side effects including nightmares, stuffy nose, depression, and an inability to fall asleep. Diarrhea and heartburn are also possible. Guanadrel and guanethidine can cause diarrhea and other gastrointestinal issues – as well as dizziness and drowsiness.
An apple a day really does keep the doctor away, particularly for those struggling with high blood pressure. In addition to the 4.5 grams of blood pressure-lowering fiber you’ll get from each apple, you’ll also enjoy a healthy helping of quercetin, which has been deemed an effective antihypertensive, according to the results of a study conducted at the University Complutense of Madrid School of Medicine.
A 2013 review on yoga and blood pressure found an average blood pressure decrease of 3.62 mm Hg diastolic and 4.17 mm Hg systolic when compared to those who didn’t exercise. Studies of yoga practices that included breath control, postures, and meditation were nearly twice as effective as yoga practices that didn’t include all three of these elements (24).
