Headaches strike over 90% of adults each year. You may be able to wait out some and let them pass, but others may be a sign that your body is asking you to take action. There is a chance that your headache could be a symptom of high blood pressure. If there are no other causes of your headache, you should ask your healthcare provider about getting your blood pressure checked.
This drug prevents calcium from entering the smooth muscle cells of the heart and arteries. When calcium enters these cells, it causes a stronger and harder contraction, so by decreasing the calcium, the hearts' contraction is not as forceful. Calcium channel blockers relax and open up narrowed blood vessels, reduce heart rate and lower blood pressure.
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.
Various organizations including the United States Department of Agriculture recommend that Americans consume less than 2,300 milligrams (mg) of sodium per day. But the ideal limit is really no more than 1,500 mg per day for most adults. Unfortunately, the average sodium intake of Americans is more than 3,400 mg per day, according to the Centers for Disease Control and Prevention (CDC). This is partly because sodium is so easy to consume — just 1 teaspoon of salt contains 2,300 mg of sodium.

I just started using high blood pressure medication and purchased a blood pressure meter at age 72. what concerns me is that the BP readings I get have a very wide variance in. I measure every morning as soon as I wake up, while still in bed and prior to having any coffee. I take 3 or 4 readings. I have found that on any given day my reading can vary from 126 to 143 systolic and the diastolic reading from 68 to 87. this wide variance makes it very difficult to track trends. My questions are: is this normal? is my instrument possibly defective? How can my cardiac doctor make a decision to put me on life long medication based on SINGLE reading in his office?
Echocardiogram is an ultrasound examination of the heart It is used to evaluate the anatomy and the function of the heart. A cardiologist is required to interpret this test and can evaluate the heart muscle and determine how thick it is, whether it moves appropriately, and how efficiently it can push blood out to the rest of the body. The echocardiogram can also assess heart valves, looking for narrowing (stenosis) and leaking (insufficiency or regurgitation). A chest X-ray may be used as a screening test to look for heart size, the shape of the aorta, and to assess the lungs.
Various expert groups have produced guidelines regarding how low the blood pressure target should be when a person is treated for hypertension. These groups recommend a target below the range 140–160 / 90–100 mmHg for the general population.[13][99][100][101][102] Cochrane reviews recommend similar targets for subgroups such as people with diabetes[103] and people with prior cardiovascular disease.[104]
In the study, Naci's team analyzed data from 197 clinical trials that assessed the effects of structured workouts on lowering systolic blood pressure, the top number in a reading. The investigators also looked at data from 194 trials that examined the impact of prescription drugs on blood pressure. In total, the studies included nearly 40,000 people.
Once the diagnosis of hypertension has been made, healthcare providers should attempt to identify the underlying cause based on risk factors and other symptoms, if present. Secondary hypertension is more common in preadolescent children, with most cases caused by kidney disease. Primary or essential hypertension is more common in adolescents and has multiple risk factors, including obesity and a family history of hypertension.[83] Laboratory tests can also be performed to identify possible causes of secondary hypertension, and to determine whether hypertension has caused damage to the heart, eyes, and kidneys. Additional tests for diabetes and high cholesterol levels are usually performed because these conditions are additional risk factors for the development of heart disease and may require treatment.[6]
In hypertensive emergency, there is evidence of direct damage to one or more organs.[27][28] The most affected organs include the brain, kidney, heart and lungs, producing symptoms which may include confusion, drowsiness, chest pain and breathlessness.[26] In hypertensive emergency, the blood pressure must be reduced more rapidly to stop ongoing organ damage,[26] however, there is a lack of randomized controlled trial evidence for this approach.[28]
Sodium (salt) sensitivity: Some people have high sensitivity to sodium (salt), and their blood pressure increases if they use salt. Reducing sodium intake tends to lower their blood pressure. Americans consume 10-15 times more sodium than they need. Fast foods and processed foods contain particularly high amounts of sodium. Many over-the-counter medicines also contain large amounts of sodium. Read food labels and learn about salt content in foods and other products as a healthy first step to reducing salt intake. Fast food restaurants also make the salt and calorie content of their food available to consumers at their restaurants,

Hypertension is diagnosed on the basis of a persistently high resting blood pressure. The American Heart Association recommends at least three resting measurements on at least two separate health care visits.[74] The UK National Institute for Health and Care Excellence recommends ambulatory blood pressure monitoring to confirm the diagnosis of hypertension if a clinic blood pressure is 140/90 mmHg or higher.[75]
An important part of a high blood pressure treatment plan is to stick to a healthy diet, including limiting sodium intake. The 2015-2020 Dietary Guidelines for Americans recommend consuming less than 2,300 milligrams (mg) of sodium per day (2). People with high blood pressure may need to restrict sodium intake even more. The American Heart Association (AHA) recommends an ideal limit of no more than 1,500 mg per day for adults with hypertension. (3)
Though essential hypertension remains somewhat mysterious, it has been linked to certain risk factors. High blood pressure tends to run in families and is more likely to affect men than women. Age and race also play a role. In the United States, blacks are twice as likely as whites to have high blood pressure, although the gap begins to narrow around age 44. After age 65, black women have the highest incidence of high blood pressure.
Heart attack. Signs of heart attack include mild or severe chest pain or discomfort in the center of the chest or upper abdomen that lasts for more than a few minutes or goes away and comes back. It can feel like pressure, squeezing, fullness, heartburn, or indigestion. There may also be pain down the left arm. Women may also have chest pain and pain down the left arm, but they are more likely to have less typical symptoms, such as shortness of breath, nausea, vomiting, unusual tiredness, and pain in the back, shoulders, or jaw. Read more about the signs and symptoms of a heart attack.
Unchecked, high blood pressure can lead to a myriad of serious health problems, such as heart attacks, strokes, and other forms of heart disease and kidney disease. It is extremely dangerous during pregnancy because it contributes to devastating and even deadly problems for moms and babies. Other impacts of hypertension include vision problems and sexual dysfunction.
2. Take the right nutrients. Talk with your chiropractor or other healthcare professional about the wide range of well-studied nutrients that, along with dietary and lifestyle modifications, can help normalize your blood pressure. One meta-analysis found magnesium supplements could lower blood pressure. Likewise, researchers find a small but significant decline in blood pressure for people with hypertension who use fish oil. (You can get all of fish oil’s benefits combined with anti-inflammatory flax oil and GLA in our Optimal Omega.) 
The first chemical for hypertension, sodium thiocyanate, was used in 1900 but had many side effects and was unpopular.[152] Several other agents were developed after the Second World War, the most popular and reasonably effective of which were tetramethylammonium chloride, hexamethonium, hydralazine, and reserpine (derived from the medicinal plant Rauwolfia serpentina). None of these were well tolerated.[159][160] A major breakthrough was achieved with the discovery of the first well-tolerated orally available agents. The first was chlorothiazide, the first thiazide diuretic and developed from the antibiotic sulfanilamide, which became available in 1958.[152][161] Subsequently, beta blockers, calcium channel blockers, angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blockers, and renin inhibitors were developed as antihypertensive agents.[158]
An important part of a high blood pressure treatment plan is to stick to a healthy diet, including limiting sodium intake. The 2015-2020 Dietary Guidelines for Americans recommend consuming less than 2,300 milligrams (mg) of sodium per day (2). People with high blood pressure may need to restrict sodium intake even more. The American Heart Association (AHA) recommends an ideal limit of no more than 1,500 mg per day for adults with hypertension. (3)
These guidelines help guide healthcare practices, and can be related to patient reimbursement and healthcare coverage. The tenth revision of the International Statistical Classification of Diseases and Related Health Problems, or ICD-10, is the set of codes used to designate specific health conditions and allow for reimbursement through health insurance programs.
Women who are taking ACE inhibitors or ARBs for high blood pressure should not become pregnant while on this class of drugs. If you're taking an ACE inhibitor or an ARB and think you might be pregnant, see your doctor immediately. These drugs have been shown to be dangerous to both mother and baby during pregnancy. They can cause low blood pressure, severe kidney failure, excess potassium (hyperkalemia) and even death of the newborn.
Events in early life, such as low birth weight, maternal smoking, and lack of breastfeeding may be risk factors for adult essential hypertension, although the mechanisms linking these exposures to adult hypertension remain unclear.[43] An increased rate of high blood urea has been found in untreated people with hypertension in comparison with people with normal blood pressure, although it is uncertain whether the former plays a causal role or is subsidiary to poor kidney function.[44] Average blood pressure may be higher in the winter than in the summer.[45] Periodontal disease is also associated with high blood pressure.[46]
If your blood pressure remains high for a long period of time, you run the risk of damaging your blood vessels. Your stroke risk rises significantly, too. And because your heart is working harder to push blood through your system, that very valuable muscle can become overworked and grow thicker. An enlarged heart causes further complications, including heart failure. Medications and special implantable pumps can help boost heart function. But if you can manage your blood pressure before it gets too high and puts your heart at risk, you may be able to avoid a lot of complications down the road.
Enlarged heart. High blood pressure increases the amount of work for your heart. Like any heavily exercised muscle in your body, your heart grows bigger (enlarges) to handle the extra workload. The bigger your heart is, the more it demands oxygen-rich blood but the less able it is to maintain proper blood flow. As a result, you feel weak and tired and are not able to exercise or perform physical activities. Without treatment, your heart failure will only get worse.
It is notable that relaxation and meditation, though useful for many purposes, have not been found to impact high blood pressure. Many people find this surprising, possibly since high blood pressure also is known as “hypertension.” Because of this potentially misleading term, many people have assumed that high levels of stress or “tension” are a major cause of “hypertension,” or high blood pressure. This is not the case. High blood pressure is an essentially mechanical, and not psychological, problem.
Lifelong control of hypertension will minimize the risk of developing heart attack, stroke, kidney failure, blindness, and a variety of other illnesses. Unlike other illnesses in which medications are taken for only a short period of time, high blood pressure medication is usually expected to be taken for the rest of the individual's life. It is uncommon, but not rare, that significant lifestyle changes can lower blood pressure readings to normal.

Dietary changes: The health care provider might recommend a diet that includes more vegetables (especially leafy green vegetables), fruits, low-fat dairy products, and fiber-rich foods, and fewer carbohydrates, fats, processed foods, and sugary drinks. He or she also might recommend preparing low-sodium dishes and not adding salt to foods. Watch out for foods with lots of hidden salt (like bread, sandwiches, pizza, and many restaurant and fast-food options).
Don’t assume that your doctor is aware of these facts. If you are diagnosed with mild, high blood pressure, you likely will be prescribed medication, instructed that it is helpful, and told that you must take it for the rest of your life. But before accepting this potentially dangerous treatment, it may be to your advantage to seek answers to the following questions: “What caused my high blood pressure?” and “Can I remove those causes and reverse this condition?”
The American Heart Association continues to call high blood pressure the “silent killer.”  There are no concrete symptoms for high blood pressure.  Headaches, dizziness, and nosebleeds (epistaxis) are not usually caused by high blood pressure, unless the patient is in Hypertensive Crisis (systolic of 180 or higher or diastolic of 110 or higher).  Facial flushing may occur with high blood pressure, but high blood pressure is not the cause of facial flushing.  Factors such as spicy foods, sun exposure, cold weather, hot drinks, medical conditions, and exercise are more of the cause of facial flushing.  Although dizziness is not the cause of high blood pressure, it may be a side effect of some blood pressure medications.  A person in Hypertensive Crisis must receive emergency care immediately.  In addition to extreme blood pressure readings, severe headaches and nosebleeds, patients may also experience severe anxiety and shortness of breath.
In people aged 18 years or older hypertension is defined as either a systolic or a diastolic blood pressure measurement consistently higher than an accepted normal value (this is above 129 or 139 mmHg systolic, 89 mmHg diastolic depending on the guideline).[5][7] Other thresholds are used (135 mmHg systolic or 85 mmHg diastolic) if measurements are derived from 24-hour ambulatory or home monitoring.[79] Recent international hypertension guidelines have also created categories below the hypertensive range to indicate a continuum of risk with higher blood pressures in the normal range. The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC7) published in 2003[27] uses the term prehypertension for blood pressure in the range 120–139 mmHg systolic or 80–89 mmHg diastolic, while European Society of Hypertension Guidelines (2007)[86] and British Hypertension Society (BHS) IV (2004)[87] use optimal, normal and high normal categories to subdivide pressures below 140 mmHg systolic and 90 mmHg diastolic. Hypertension is also sub-classified: JNC7 distinguishes hypertension stage I, hypertension stage II, and isolated systolic hypertension. Isolated systolic hypertension refers to elevated systolic pressure with normal diastolic pressure and is common in the elderly.[27] The ESH-ESC Guidelines (2007)[86] and BHS IV (2004)[87] additionally define a third stage (stage III hypertension) for people with systolic blood pressure exceeding 179 mmHg or a diastolic pressure over 109 mmHg. Hypertension is classified as "resistant" if medications do not reduce blood pressure to normal levels.[27] In November 2017, the American Heart Association and American College of Cardiology published a joint guideline which updates the recommendations of the JNC7 report.[88] 

A blood pressure reading measures both the systolic and diastolic forces, with the systolic pressure listed first. The numbers show your pressure in units of millimeters of mercury (mm Hg)—how high the pressure inside your arteries would be able to raise a column of mercury. For example, a reading of 120/80 mm Hg means a systolic pressure of 120 mm Hg and diastolic pressure of 80 mm Hg.
Dizziness : While dizziness can be a side effect of some blood pressure medications, it is not caused by high blood pressure. However, dizziness should not be ignored, especially if the onset is sudden. Sudden dizziness, loss of balance or coordination and trouble walking are all warning signs of a stroke. High blood pressure is a leading risk factor for stroke.
Beta-blockers cause the heart to slow down and so some of their side effects can be traced to that mechanism of action. Dizziness, weakness, fatigue, and fainting are possible. Beta-blockers also affect the respiratory system, so other side effects include shortness of breath, difficulty breathing, and chest pain. Beta-blockers should not be withdrawn suddenly, as that could result in a heart attack or sudden death.
For most people, the first-choice medication for high blood pressure is a thiazide diuretic. For other people, a diuretic alone is not enough to control blood pressure. In these cases, a diuretic may be combined with a beta-blocker, ACE inhibitor, angiotensin II receptor blocker, or calcium channel blocker. Adding a second medication may lower your blood pressure more quickly than using a diuretic alone. Also, it allows you to take less of each medication, which may reduce side effects.
Imagine a garden hose hooked up to a spigot. When the hose is flexible and there are no kinks in it, you can turn on the water full blast and it will flow easily through the hose. But if there’s a kink in the hose, the water doesn’t flow as well beyond the kink. And the pressure inside the hose builds up behind the kink. Or imagine there is gunk inside the hose blocking the path of the water. Your arteries are a lot like that garden hose.
Elevated blood pressures in the medical setting may not necessarily reflect the individuals real status. "White coat hypertension" describes a patient whose blood pressure is elevated because of the stress of the visit to the doctor or other healthcare professional, and the worry that their blood pressure might be elevated. Repeated blood pressure checks at the doctor's office or the use of a home blood pressure monitoring device may be used to confirm that you have high blood pressure.

Serum creatinine is measured to assess for the presence of kidney disease, which can be either the cause or the result of hypertension. Serum creatinine alone may overestimate glomerular filtration rate and recent guidelines advocate the use of predictive equations such as the Modification of Diet in Renal Disease (MDRD) formula to estimate glomerular filtration rate (eGFR).[27] eGFR can also provide a baseline measurement of kidney function that can be used to monitor for side effects of certain anti-hypertensive drugs on kidney function. Additionally, testing of urine samples for protein is used as a secondary indicator of kidney disease. Electrocardiogram (EKG/ECG) testing is done to check for evidence that the heart is under strain from high blood pressure. It may also show whether there is thickening of the heart muscle (left ventricular hypertrophy) or whether the heart has experienced a prior minor disturbance such as a silent heart attack. A chest X-ray or an echocardiogram may also be performed to look for signs of heart enlargement or damage to the heart.[23]
Check out the blood pressure charts below to find out whether your values are within normal limits or try out our tool to help you evaluate your blood pressure figures more accurately. It is advisable to regularly monitor blood pressure values in order to detect any deviations early. Periodic checks can be done at home, using an appropriate and certified monitor, or by regular check-ups with your personal doctor.
