You can have high blood pressure, or hypertension, and still feel just fine. That's because high blood pressure often does not cause signs of illness that you can see or feel. But, high blood pressure, sometimes called "the silent killer," is very common in older people and a major health problem. If high blood pressure isn't controlled with lifestyle changes and medicine, it can lead to stroke, heart disease, eye problems, kidney failure, and other health problems. High blood pressure can also cause shortness of breath during light physical activity or exercise.
Note: The fasting and high blood pressure study described in this article was funded in part by a grant from the National Health Association. It was conducted at the Center for Conservative Therapy in Penngrove, California. The results appeared in the article, “Medically Supervised Water-Only Fasting in the Treatment of Hypertension,” published in June 2001 in the Journal of Manipulative and Physiological Therapeutics.
Your circulatory system is very much like the hot tub’s. Your blood is like the water. Your heart is like the pump, and your blood vessels are like the pipes. Your heart pumps your blood through the circulatory system in order to feed oxygen and nutrients to cells throughout your body, and to remove waste products. By circulating through the system, your blood is filtered and re-utilized, again and again.
The medical world experienced yet another guideline update in 2018 telling doctors more medication is better. This guideline for treating hypertension was put out by the American College of Cardiology and the American Heart Association, and effectively lowered the definition of hypertension from 140/90 down to 130/80. The organizations also recommended drug treatment for all individuals with blood pressure greater than 140/90, regardless of underlying risk.

Stress hormones constrict your blood vessels and can lead to temporary spikes in blood pressure. In addition, over time, stress can trigger unhealthy habits that put your cardiovascular health at risk. These might include overeating, poor sleep, and misusing drugs and alcohol. For all these reasons, reducing stress should be a priority if you're looking to lower your blood pressure.


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]
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.
My blood pressure is 120/84 with a pulse of 94. 30 minutes prior to that it was 118/85 with a pulse rate of 101. I wasn’t doing anything but just sitting. I’ve noticed that my pulse is always between 85-99. I’ve seen a cardiologist and my stress test and echocardiogram has all come back normal. Should I be concern with these numbers. I have an autoimmune disease but I’m not sure if that would cause the fluctuations. Can someone help or make suggestions? Thanks
Many mechanisms have been proposed to account for the rise in peripheral resistance in hypertension. Most evidence implicates either disturbances in the kidneys' salt and water handling (particularly abnormalities in the intrarenal renin–angiotensin system)[61] or abnormalities of the sympathetic nervous system.[62] These mechanisms are not mutually exclusive and it is likely that both contribute to some extent in most cases of essential hypertension. It has also been suggested that endothelial dysfunction and vascular inflammation may also contribute to increased peripheral resistance and vascular damage in hypertension.[63][64] Interleukin 17 has garnered interest for its role in increasing the production of several other immune system chemical signals thought to be involved in hypertension such as tumor necrosis factor alpha, interleukin 1, interleukin 6, and interleukin 8.[65]
Peter, I’ve been using a blood pressure meter for nearly 30 years, so my response is based on my personal experience and information I’ve acquired over the years. First, I suggest that you take your meter to the doctor and have them check several readings of your meter against theirs. For example, If your meter consistently shows it’s 10 points lower than the doctor’s, just delete the 10 points from your meter reading (have them check both numbers so you can adjust both as necessary). Also, it’s common that many doctor’s offices take your blood pressure incorrectly (you should actually sit still for 5 minutes, with your feet on the floor and the cuff at the same level as your heart) . Some of us have”white coat” hypertension, so you may always be elevated at the doctor’s office. If you are a large man, you (and your doctor’s office) may need to use a larger cuff as the wrong size of cuff can affect your reading. Also, I spoke with customer service at one of the companies that makes many of the home & professional meters, and she told me that the automated machines are not very accurate if you have kidney disease or heart failure (I have both). Ask the doctor’s staff to always use the manual system and it will be more accurate than those noisy automatic ones.
Guanadrel (Hylorel)* or guanethidine (Ismelin)* may cause some diarrhea, which may persist in some people. This side effect usually becomes less of a problem if you continue treatment. These drugs reduce blood pressure more when you stand. Consequently, you may get dizzy and lightheaded and feel weak when you get out of bed in the morning or stand up suddenly. If you notice any of these reactions and if they persist for more than a minute or two, contact your doctor. He/she may instruct you to reduce or omit the next dose of the medication.
4. Find an exercise that works for you (and do it). Moving more can help reverse high blood pressure. One meta-analysis of 65 studies found regular exercise provides both an acute and longer-term reduction in blood pressure. Whether you’re an exercise novice or a conditioned athlete, these four strategies can help you create an effective workout plan to optimize health.

Editor’s Note: Considerable controversy exists about whether fat or cholesterol are, per se, drivers of atherosclerosis. They are implicated in some studies, while others indicate that quality of fat, and placement in a wider dietary pattern, may be more significant to ultimate impact. What seems clear, however, is that a diet high in animal products, sugar, and processed foods is often a recipe for high blood pressure and heart disease.
Blood pressure control is a lifelong challenge. Hypertension can progress through the years, and treatments that worked earlier in life may need to be adjusted over time. Blood pressure control may involve gradually making lifestyle changes like diet, weight loss, exercise, and possibly taking medicine if necessary. In some situations, medications may be recommended immediately. As with many diseases, you and your doctor should work together to find the treatment plan that works for you.

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.

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]
High blood pressure can cause problems for a mother and her baby. High blood pressure can harm a mother’s kidneys and other organs and can cause early birth and low birth weight. If you are thinking about having a baby and have high blood pressure, talk with your doctors so you can take steps to lower or control your high blood pressure before and during the pregnancy.
The fact that there are so many drugs to choose from means at least two things. First, it means there is no “best” drug for hypertension, that is, there is no drug that works well for almost everyone without causing unacceptable adverse effects. If there were, drug companies would have stopped their efforts to develop new antihypertensive drugs long ago—and the list of approved drugs would be much shorter.
The World Health Organization has identified hypertension, or high blood pressure, as the leading cause of cardiovascular mortality.[162] The World Hypertension League (WHL), an umbrella organization of 85 national hypertension societies and leagues, recognized that more than 50% of the hypertensive population worldwide are unaware of their condition.[162] To address this problem, the WHL initiated a global awareness campaign on hypertension in 2005 and dedicated May 17 of each year as World Hypertension Day (WHD). Over the past three years, more national societies have been engaging in WHD and have been innovative in their activities to get the message to the public. In 2007, there was record participation from 47 member countries of the WHL. During the week of WHD, all these countries – in partnership with their local governments, professional societies, nongovernmental organizations and private industries – promoted hypertension awareness among the public through several media and public rallies. Using mass media such as Internet and television, the message reached more than 250 million people. As the momentum picks up year after year, the WHL is confident that almost all the estimated 1.5 billion people affected by elevated blood pressure can be reached.[163]
When added to a healthy diet, almonds can help influence lower blood pressure levels. In fact, almonds are included in the Dietary Approaches to Stop Hypertension — DASH — Diet. In the diet, almonds are included in the “nuts, seeds and legumes” group. The diet recommends eating four to five servings of this food group per week. With regard to almonds, one serving of almonds is just one-third cup. The healthy monounsaturated fat in almonds contributes to lower blood cholesterol levels and reduced arterial inflammation, which ultimately helps lower the pressure inside the arteries.

Blood pressure is measure in millimeters of mercury (mmHg) and recorded as two numbers, systolic and diastolic. Systolic is the top number (also the higher one), which measure the pressure in the arteries when the heart beats, so when its muscles contract. Diastolic the bottom number (also the lower one), which measures the pressure in the arteries between heart beats, so when the muscles relax and refill with blood.
