For older people, often the first number (systolic) is 130 or higher, but the second number (diastolic) is less than 80. This problem is called isolated systolic hypertension, which is due to age-related stiffening of the major arteries. It is the most common form of high blood pressure in older people and can lead to serious health problems (stroke, heart disease, eye problems, and kidney failure) in addition to shortness of breath during light physical activity, lightheadedness upon standing too fast, and falls. Isolated systolic hypertension is treated in the same way as regular high blood pressure (130 or higher for the first number, or 80 or higher for the second number) but may require more than one type of blood pressure medication. If your doctor determines that your systolic pressure is above a normal level for your age, ask how you can lower it.
“We don’t think, on the basis of our study, that patients should stop taking their antihypertensive medications,” says Naci. It’s one thing to recommend that physicians start prescribing exercise to their patients, but we also need to ensure that the patients that have been referred to exercise interventions can adhere to them and so really derive benefit, he says.
Instead of reaching for drugs, we should continue to find the most effective lifestyle interventions to help lower blood pressure and reduce cardiovascular risk without a laundry list of side effects. Unless, of course, you consider losing weight, having more energy, and feeling great as side effects — those are the type of side effects (from low-carb eating) that we all can embrace!
"Blood pressure guidelines are not updated at regular intervals. Instead, they are changed when sufficient new evidence suggests the old ones weren't accurate or relevant anymore," says Dr. Paul Conlin, an endocrinologist with Harvard-affiliated VA Boston Healthcare System and Brigham and Women's Hospital. "The goal now with the new guidelines is to help people address high blood pressure — and the problems that may accompany it like heart attack and stroke — much earlier."
Many leafy greens, including everything arugula and kale to spinach and collard greens, contain potassium and magnesium which are key minerals to control blood pressure, according to Harvard Medical School. These nutrients are an important part of the DASH diet (Dietary Approaches to Stop Hypertension, or high blood pressure), which suggests a variety of foods that lower blood pressure. A potassium-rich diet helps the body become more efficient at flushing out excess sodium, which can raise blood pressure, and magnesium helps promote healthy blood flow, according to nutritionist Joy Bauer.
If your blood pressure is 120/80 millimeters of mercury (mm Hg) or lower, it’s considered normal. Generally, if the blood pressure reading is under 90/60 mm Hg, it is abnormally low and is referred to as hypotension. Some adults regularly have a blood pressure in the hypotensive range, but have no symptoms at all and do not require treatment. In serious cases, though, hypotension can result in a decreased supply of oxygen and nutrients to your brain, which can eventually lead to life-threatening shock.
High blood pressure is the most common chronic medical problem prompting visits to primary health care providers in USA. The American Heart Association estimated the direct and indirect costs of high blood pressure in 2010 as $76.6 billion. In the US 80% of people with hypertension are aware of their condition, 71% take some antihypertensive medication, but only 48% of people aware that they have hypertension adequately control it. Adequate management of hypertension can be hampered by inadequacies in the diagnosis, treatment, or control of high blood pressure. Health care providers face many obstacles to achieving blood pressure control, including resistance to taking multiple medications to reach blood pressure goals. People also face the challenges of adhering to medicine schedules and making lifestyle changes. Nonetheless, the achievement of blood pressure goals is possible, and most importantly, lowering blood pressure significantly reduces the risk of death due to heart disease and stroke, the development of other debilitating conditions, and the cost associated with advanced medical care.
Many kids and teens with high blood pressure have an unhealthy lifestyle — a bad diet, excess weight, stress, and too little physical activity. So the health care provider might recommend weight loss, exercise, reduced screen time (time spent watching TV, or using a computer or mobile devices), dietary changes, and even relaxation techniques. Teens with hypertension should not smoke because it can make the long-term associated heart problems worse.
Modern understanding of the cardiovascular system began with the work of physician William Harvey (1578–1657), who described the circulation of blood in his book "De motu cordis". The English clergyman Stephen Hales made the first published measurement of blood pressure in 1733. However, hypertension as a clinical entity came into its own with the invention of the cuff-based sphygmomanometer by Scipione Riva-Rocci in 1896. This allowed easy measurement of systolic pressure in the clinic. In 1905, Nikolai Korotkoff improved the technique by describing the Korotkoff sounds that are heard when the artery is ausculated with a stethoscope while the sphygmomanometer cuff is deflated. This permitted systolic and diastolic pressure to be measured.
For obese people or people with family history of high blood pressure, you need to watch your blood pressure. Your total blood pressure reading is determined by measuring your systolic and diastolic blood pressures. Systolic BP, the top number, measures the force your heart exerts on the walls of your arteries each time it beats. Diastolic BP, the bottom number, measures the force your heart exerts on the walls of your arteries in between beats. Below is a blood pressure chart by age.
Coconut water finds itself high on the list of home remedies for high blood pressure. One of the causes for high blood pressure is an imbalance of electrolytes in the blood. Because coconut water contains an adequate supply of minerals and salts, it can help counter this imbalance. Modern researchers say the potassium content in coconut water plays a huge role in lowering blood pressure. Both potassium chloride (seen in supplements) and potassium citrate (seen in foods) can help lower blood pressure. Potassium helps balance out the level of sodium in your blood and keeps your body functioning properly.
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.

High blood pressure, also known as hypertension (See blood pressure chart below) is called the “silent killer” for a reason — there are no obvious symptoms but it can result in heart attack, stroke and even death. The good news is there’s a lot you can do to maintain healthy blood pressure or get back to one, often without the need for medications.
Some of these drugs may decrease your body's supply of the mineral potassium. Symptoms such as weakness, leg cramps or being tired may result. Eating foods containing potassium may help prevent significant potassium loss. If your doctor recommends it, you could prevent potassium loss by taking a liquid or tablet that has potassium along with the diuretic. Diuretics such as amiloride (Midamar)*, spironolactone (Aldactone)* or triamterene (Dyrenium)* are called "potassium sparing" agents. They don't cause the body to lose potassium. They might be prescribed alone, but are usually used with another diuretic. Some of these combinations are Aldactazide*, Dyazide*, Maxzide* or Moduretic*.
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.
Blood pressure is expressed by two measurements, the systolic and diastolic pressures, which are the maximum and minimum pressures, respectively. For most adults, normal blood pressure at rest is within the range of 100–130 millimeters mercury (mmHg) systolic and 60–80 mmHg diastolic. For most adults, high blood pressure is present if the resting blood pressure is persistently at or above 130/80 or 140/90 mmHg. Different numbers apply to children. Ambulatory blood pressure monitoring over a 24-hour period appears more accurate than office-based blood pressure measurement.
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.
Regular visits with your doctor are also key to controlling your blood pressure. If your blood pressure is well-controlled, check with your doctor about how often you need to check it. Your doctor may suggest checking it daily or less often. If you're making any changes in your medications or other treatments, your doctor may recommend you check your blood pressure starting two weeks after treatment changes and a week before your next appointment.
