According to the Centers for Disease Control and Prevention (CDC), an estimated 75 million Americans have high blood pressure. Many risk factors for high blood pressure are out of your control, such as age, family history, gender, and race. But there are also factors you can control, such as exercise and diet. A diet that can help control blood pressure is rich in potassium, magnesium, and fiber and lower in sodium.
Reduce processed sugar and refined carbohydrates. Many studies have shown a link between high blood pressure and processed sugar. Even moderate amounts of sugar can raise blood pressure. For example, during the Framingham Women’s Health Study, women who drank as little as one soda per day had higher blood pressure than women who drank less. It’s not just sweet sugar that raises blood pressure. Refined carbohydrates, like white bread and pasta, covert to sugar quickly when they’re eaten, and they may also cause blood pressure to rise. There is evidence that reducing refined sugar intake can lower blood pressure and improve heart health.
Your blood pressure is considered high when you have consistent systolic readings of 140 mm Hg or higher or diastolic readings of 90 mm Hg or higher. Based on research, your doctor may also consider you to have high blood pressure if you are an adult or child age 13 or older who has consistent systolic readings of 130 to 139 mm Hg or diastolic readings of 80 to 89 mm Hg and you have other cardiovascular risk factors.
Blood pressure guidelines show the lower the blood pressure numbers the better. As long as no symptoms of trouble are present there is no one number that doctors consider being too low. The guidelines call for an individualized, risk-based approach to managing hypertension, as well as a personal consultation with a health care provider. While the new guidelines mean we are more aggressive about blood pressure control, lifestyle changes are always a part of the treatment plan. A treatment plan is agreed to by patient and provider, and includes ongoing communication to see how the patient is feeling and how their medications are working.
This study is assessing whether a low-sodium and low-calorie eating pattern, along with aerobic exercise, can improve blood pressure in patients who do not respond to high blood pressure medicines. To participate you must be at least 35 years and have high blood pressure that does not respond to medicines. Please note that this study is in Durham, North Carolina.
Diuretics can lead to an increase in potassium loss, known as hypokalemia, which, in turn can affect muscular function -- including the muscles of the heart. There is also an increased risk for gout with diuretics -- as well as the possibility of weakness, thirst, dehydration, and increased urination. Changes in blood sugar levels are also possible. Skin reactions, some severe, are possible with thiazide diuretics (such as hydrochlorothiazide). Potassium-sparing diuretics, such as spironolactone (Aldactone) may cause breast enlargement in males.
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.
Treatment for high blood pressure is decided based on current medical conditions. In some cases, intravenous therapy is started on emergency basis while further tests are conducted to identify the pathology in other cases. Based on the outcomes, a regimen is provided by the doctor in order to control the blood pressure. If high blood pressure results from different pathologies, then multiple therapies may also be conducted. In more severe cases such as advanced kidney damage or tumors, surgical intervention may also have to be carried out."
In November, the American Heart Association and the American College of Cardiology issued new guidelines that change how high blood pressure, or hypertension, is diagnosed. Previously, it wasn’t until an adult’s blood pressure reached 140 mmHg or higher systolic (the top, or first, number) or 90 mmHg diastolic (the bottom, or second, number) or higher that high blood pressure was diagnosed. According to the new parameters, high blood pressure should be treated at 130/80 rather than 140/90, as that is the point when our risk for heart attack, stroke, and other consequences for hypertension almost doubles.
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.
Stress reduction techniques such as biofeedback or transcendental meditation may be considered as an add-on to other treatments to reduce hypertension, but do not have evidence for preventing cardiovascular disease on their own. Self-monitoring and appointment reminders might support the use of other strategies to improve blood pressure control, but need further evaluation.
Changes in blood vessel structure. Blood vessels have layers of the proteins elastin and collagen. Elastin is what makes blood vessels flexible. Collagen, which is stiffer, gives vessels structure. With age, elastin breaks down. Even the elastin that remains becomes less elastic. Meanwhile, collagen deposits in the vessels increase. As a result, blood vessels grow thicker and bend less easily over time. These changes may lead to higher systolic blood pressure.
Note – always consult your personal doctor if you are unsure whether your numbers are too high or too low. If symptoms are present you need to visit your doctor promptly. Often times, an underlying problem may affect your numbers. It is always best to first try and change your lifestyle (abandon smoking, more exercise, proper diet) to mitigate the problem, however in some circumstances drugs will be your only option to keep things under control.
Most people with high blood pressure are "salt sensitive," meaning that anything more than the minimal bodily need for salt is too much for them and increases their blood pressure. Other factors that can raise the risk of having essential hypertension include obesity; diabetes; stress; insufficient intake of potassium, calcium, and magnesium; lack of physical activity; and chronic alcohol consumption.

Blood pressure refers to the force exerted by circulating blood on the walls of blood vessels and constitutes one of the principal vital signs. The pressure of the circulating blood decreases as blood moves through arteries, arterioles, capillaries, and veins; the term blood pressure generally refers to arterial pressure, i.e., the pressure in the larger arteries, arteries being the blood vessels which take blood away from the heart.
Historically the treatment for what was called the "hard pulse disease" consisted in reducing the quantity of blood by bloodletting or the application of leeches. This was advocated by The Yellow Emperor of China, Cornelius Celsus, Galen, and Hippocrates. The therapeutic approach for the treatment of hard pulse disease included changes in lifestyle (staying away from anger and sexual intercourse) and dietary program for patients (avoiding the consumption of wine, meat, and pastries, reducing the volume of food in a meal, maintaining a low-energy diet and the dietary usage of spinach and vinegar).
Beta blockers decrease the effect of adrenaline on the cardiovascular system, slow the heart rate, and reduce stress on the heart and the arteries. Side effects include worsening shortness of breath if you have chronic obstructive pulmonary disease or asthma; sexual dysfunction; fatigue; depression; and worsening of symptoms if you have peripheral artery disease. Beta-blocker examples include:
