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). 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.
Some research on watermelon extract and high blood pressure suggests the amino acid citrulline found in the fruit may help manage high blood pressure. One study found those who took watermelon extract showed reduced blood pressure specifically in the ankles and arm arteries. Other studies on mice also show watermelon’s positive effect. Although more research is needed to determine the specifics, eating fruit like watermelon isn’t going to hurt.
Blood pressure is the measure of the force of blood pushing against blood vessel walls. The heart pumps blood into blood vessels, which carry the blood throughout the body. High blood pressure, also called hypertension, is dangerous because it makes the heart work harder to pump blood out to the body and contributes to hardening of the arteries, or atherosclerosis, to stroke, kidney disease, and to heart failure.
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.
It is normal that blood pressure fluctuates during the day. Consecutive measurement will show a circadian rhythm over a 24-hour period. Usually highest reading will be observed in the morning, while lowest readings will be observed in the evening or during the night, when body is at rest. It is also important to note that blood pressure values may be affected by adrenaline, emotions, exercise, sleep patterns and digestion so make sure you pick a good time to do the screening, or otherwise your measurements will not be accurate. It is advisable to repeat the measurement up to three times in a row (with a pause of few minutes in between) to establish a correct value.
The JAMA study was an extensive chart review of over 38,000 patients at low risk for heart disease who had stage two hypertension (blood pressure between 149/90 and 159/99) and were treated with blood pressure medications. Over an average follow-up time of almost six years, they found no reduction in the risk of cardiovascular disease events or risk of death with medication use. They did, however, find an increased risk for low blood pressure, fainting, and acute kidney injury among those treated with medications.
Consider once again the analogy of the garden hose. If you turn on the water “harder,” there is more pressure in the hose. Excessive salt in the diet can result in excessive fluid volume in the blood, which results in elevated blood pressure. This cause, too, is reversible, as a plant-based diet of whole, natural foods, devoid of added salt, is naturally low in sodium chloride.
You may be directed to seek medical care if blood pressure readings are elevated if done as part of a community health screening. Isolated elevated blood pressure readings do not necessarily make the diagnosis of hypertension. Blood pressure readings vary throughout the day, and your primary care provider may record a different reading than the one that was measured in a screening that sent you in for care.

As you get older, high blood pressure, especially isolated systolic hypertension, is more common and can increase your risk of serious health problems. Treatment, especially if you have other medical conditions, requires ongoing evaluation and discussions with your doctor to strike the best balance of reducing risks and maintaining a good quality of life.
Hypertensive Crisis This is an occurrence of high blood pressure that requires medical attention. If you have a blood pressure reading of 180/120 mm Hg, wait five minutes and test again. If it is consistently this high, contact your doctor immediately. If blood pressure is higher than 180/120 mm Hg and you are experiencing chest pain, shortness of breath, back pain, numbness and weakness, change in vision, and difficulty speaking, you may have organ damage and should call 911.

Often, hypertension can improve with lifestyle changes. In some cases, high blood pressure can go down to normal levels with only lifestyle modifications, particularly if you have stage 1 hypertension (systolic blood pressure of 130 mmHg to 159 mmHg, or diastolic blood pressure 80 mmHg to 99 mmHg), or if you have elevated blood pressure (systolic blood of 120 mmHg to 129 mmHg and diastolic less than 80 mmHg).
Some heart attacks are sudden and intense, however most heart attacks start slowly with mild pain and discomfort. Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness or pain. Shortness of breath may occur, as well as nausea, or lightheadedness. It is vital to get help immediately if any of these symptoms occur.
Normal blood pressure is less than 120/80. Knowing your blood pressure and remembering to check it regularly can help save your life. Choosing healthier, heart-conscious foods, maintaining a healthy weight, getting up and staying active, and managing your stress are great ways to help keep your blood pressure at the level it should be. Learn more about what you can do to help control your blood pressure.
Methyldopa, formerly known under the brand name Aldomet, is one of the oldest blood pressure medications still in use. It was first introduced more than 50 years ago. Methyldopa works in the central nervous system to lower blood pressure. While its general use has declined over the years, methyldopa is considered the first-line of treatment for high blood pressure that develops during pregnancy.
*All medications have both common (generic) and brand names. The brand name is what a specific manufacturer calls the product (e.g., Tylenol®). The common name is the medical name for the medication (e.g., acetaminophen). A medication may have many brand names, but only one common name. This article lists medications by their common names. For information on a given medication, check our Drug Information database. For more information on brand names, speak with your doctor or pharmacist.
Some people may ask why doctors are lowering the threshold for high blood pressure, when it was already difficult for many patients to achieve the previous blood pressure targets of below 140 mm Hg/90 mm Hg, said Dr. Pamela B. Morris, a preventive cardiologist and chairwoman of the ACC's Prevention of Cardiovascular Disease Leadership Council. However, Morris said that the guidelines were changed because "we now have more precise estimates of the risk of [high] blood pressures," and these new guidelines really communicate that risk to patients. So, just because it's going to be difficult for people to achieve, "I don't think it's a reason not to communicate the risk to patients, and to empower them to make appropriate lifestyle modifications," Morris told Live Science.

Eat berries. Berries have many health benefits, and one of them is improving blood pressure and reducing other heart disease risks. Berries, like strawberries, raspberries, blackberries, and blueberries, have lots of polyphenols, which are great for your heart. They’re also really tasty. So, load up on the berries for better blood pressure. If you don’t like eating them all the time, try adding them to a smoothie made with low-fat or fat-free yogurt without added sugar. Throw in some ice, banana, and low-fat milk for a heart-healthy treat.
A cold glass of milk offers a solid serving of both calcium and vitamin D, nutrients that work as a team to help lower blood pressure by 3 to 10 percent, according to Bauer’s website. Those numbers may not sound impressive, but they could translate to a 15 percent reduction in heart disease risk, she adds. Other research suggests that people with low levels of calcium are at greater risk of high blood pressure. Don’t miss these 18 other natural remedies for high blood pressure.
Dr. Rachel Bond, associate director of the Women's Heart Health Program at Lenox Hill Hospital in New York City, who was not involved with the guidelines, said she agreed with the new updates. "I believe this will allow for earlier detection [of high blood pressure], and allow for more lifestyle modification to prevent the long-term detrimental effects of untreated high blood pressure," Bond said.
As of 2014, approximately one billion adults or ~22% of the population of the world have hypertension. It is slightly more frequent in men, in those of low socioeconomic status, and it becomes more common with age. It is common in high, medium, and low income countries. In 2004 rates of high blood pressure were highest in Africa, (30% for both sexes) and lowest in the Americas (18% for both sexes). Rates also vary markedly within regions with rates as low as 3.4% (men) and 6.8% (women) in rural India and as high as 68.9% (men) and 72.5% (women) in Poland. Rates in Africa were about 45% in 2016.
Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure.
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. 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.

Current strategies for controlling cardiovascular disease (CVD) risk factors, such as high blood pressure and high cholesterol, are not widely used as standard practice. CDC developed this guide to provide health professionals with evidence-based strategies for effective and sustainable CVD prevention, including health and economic impact and potential for reducing health disparities.
First, we collect and analyze statewide data using telephone surveys, hospital information, and death certificates, so we are able to know which groups of people are experiencing hypertension and the impacts of uncontrolled high blood pressure. This includes looking at geography, age, racial/ethnic status, education levels, and other demographic information. When the data is compiled, we make it available on the DOH web site. We estimate that in 2015, nearly 14,000 deaths and 71,000 hospitalizations were due to heart disease and stroke.
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.
