Fish oil.
All the evidence shows that supplementation of fish oil modestly reduce the systolic pressure (reduction of approximately 3.5 mmHg) and diastolic (decrease of approximately 2.5 mmHg) in patients with. Fish oil, a good source of omega-3 fatty acids exert a protective effect on the cardiovascular system in several respects. They act positively on the rate of blood lipids on vascular function, heart rate, platelet function, inflammation, etc.
Determination
- To reduce blood pressure moderately, it is advised to consume 900 mg of EPA / DHA per day, or taking a supplement of fish oil or by eating fatty fish every day or by combining the two contributions.
Likely effectiveness Biofeedback.
This intervention technique allows the patient to see the information from the body (brain waves, blood pressure, body temperature, etc..) On an electronic device, can then react and "educate" to reach a state of nerve and muscle relaxation. A meta-analysis of 22 randomized studies controls, published from 1966 to 2001, shows significant results obtained from the treatment of hypertension by biofeedback. These studies have a total of 905 people with hypertension. Overall, the results indicate that, compared to simple clinic visits or self-recording of blood pressure, biofeedback has a positive effect on higher blood pressure. These effects were comparable to those of a non-specific behavioral intervention (relaxation or stress management, for example). In addition, the results are even better when the technique of biofeedback combined with relaxation assisted. Biofeedback is usually in the context of behavioral therapy or rehabilitation physiotherapy.
Coenzyme Q10
likely effectiveness. Taken in oral form, this antioxidant has been shown effective in several clinical trials as adjutant treatment for hypertension. In three double-blind trials with placebo (217 subjects in total), researchers have found that coenzyme Q10 (a total of 120 mg to 200 mg per day obtained by taking 60 mg to 100 mg twice daily this supplement) lowered blood pressure and reduces the dosage of medication hypotensive .
Determination
The dosages used in studies on hypertensive subjects ranged from 60 mg to 100 mg twice a day.
Likely effectiveness Qi Gong.
From the Traditional Chinese Medicine, Qi Gong practiced regularly seeks to strengthen and relax the musculoskeletal structure, to optimize all the functions of the body, and even to ensure longevity. A systematic review published in 2007 identified 12 randomized clinical trials including a total of more than 1 000 participants15. The results suggest that regular practice of Qi Gong could have positive effects on reducing blood pressure. According to summaries of two other studies, the practice of Qi Gong (with medication) decreases the risk of stroke, reducing the dose of medication required to control blood pressure and also reduces the . It seems that the Qi Gong act by reducing stress and stabilizing the activity of the sympathetic nervous system.
Possible efficiency Tai Chi. During a search of randomized 12-week program of tai chi has proved as effective as aerobic exercise of moderate to lower blood pressure in 62 subjects aged 60 years or older who did not exercise before étude18. This study tends to show that light exercise may be sufficient to reduce blood pressure in elderly people. A more recent study (2003) produced similar results: after 12 weeks of tai chi practiced three times a week by 76 patients Prehypertensive or stage 1 hypertension, there were significant reductions in systolic pressure and diastolic (about 15.6 mmHg and 8.8 mmHg, respectively) and a marked improvement in the profile lipids.
Training effectiveness can autogenic. This technique of deep relaxation close to the suggestion autohypnose uses and concentration to eliminate the stress of any kind that the body accumulates. Some indicate that autogenic training may alone or in conjunction with conventional treatments, help reduce blood pressure. The authors note that the bias in methodology make it difficult to interpret the results. Autogenic training was particularly effective when the pressure remained high despite medication and in cases of mild hypertension rather than moderate.
Acupuncture effectiveness uncertain. Some small indicate that acupuncture lowers blood pressure. However, a clinic test conducted with 192 subjects with hypertension, treatment of acupuncture (in this case, the subjects received a maximum of 12 acupuncture sessions in six to eight weeks) to help reduce blood pressure, but not more than a placebo treatment acupuncture (needles inserted randomly into the skin).
Effectiveness uncertain Garlic (Allium sativum). The World Health Organization indicates that garlic may be useful in case of moderate hypertension. Several clinical trials show that garlic can actually be helpful at this chapter. However, according to the authors of a recent meta-analysis, the majority of these studies report an effect not statistically significant and their methodology is poor quality.
Calcium effectiveness uncertain. In many studies have found a link, yet poorly understood, between hypertension and poor calcium metabolism, manifested particularly by poor retention of this mineral. Researchers believe that calcium from food source to help maintain normal blood pressure and protect the cardiovascular system. Diet designed to stop hypertension (DASH) is also rich in calcium. In terms of supplementation, the clinical efficacy of calcium is not established. According to two meta-analysis (1996 and 1999), taking calcium supplements would be very modest reduction in the pressure. It could just as well as additional benefits of calcium for people whose diet is deficient in mineral.
Effectiveness uncertain Vitamin C. The effect of vitamin C on the blood raises the interest of researchers, but so far the results of studies.
Yoga effectiveness uncertain. Some clinical trials indicate that the daily practice of yoga is an effective tool to reduce blood pressure in people, although its effect is lower than medication. Note that we identified a study in the scientific literature which concluded that the ineffectiveness of yoga exercises and stress management to control the voltage.
Note on potassium supplements. Clinical trials indicate that in cases of hypertension, the contribution of potassium supplements in the form brings a slight decrease (about 3 mmHg) of the voltage . Given the risks associated with taking potassium supplements, doctors and naturopaths recommend instead to take the potassium in food. Fruits and vegetables are good sources. Potassium see file for more information.
Note on the magnesium supplements. In North America, medical authorities recommend a high intake of magnesium to prevent and treat hypertension, including by adopting the DASH diet. This scheme is also rich in potassium, calcium and fiber. Furthermore, the results of a meta-analysis of 20 clinical trials indicate that magnesium supplementation can reduce the voltage slightly artery,.

Exercise during Hypertension
Cardiovascular exercises like brisk walking, running, cycling, dance, swimming are recommended. It is suggested to be approximately 30 minutes per day. In the long term, it reduces the pressure of 4 mmHg systolic and 9 mmHg, even without loss of poids9.
However, caution with exercises that require lifting weights (at the gym, for example). They become against-indicated when the voltage is high.
In any case, it is best to seek the advice of his doctor before starting any exercise program.
Weight loss
In case of overweight, weight loss is the most effective method to reduce blood pressure. On average, the fact of losing 2 and a half kilos (5 pounds) leads to a decrease in systolic pressure by 5 mmHg and diastolic by 2.5 mmHg.
Antistress Measures :
Stress, impatience and hostility plays an important role in the onset of hypertension. Some experts believe that stress can vary from 10% in blood pressure. Many doctors recommend approaches such as meditation, relaxation or yoga. Performed regularly (at least two or three times a week), they can give good results. People can expect to reduce high blood pressure of 10 mmHg systolic and diastolic pressure of 5 mmHg12, for example.
Parallel to these practices will avoid unnecessary hassle. It is therefore learn to reduce stress factors related to lifestyle to better manage his time, determine its priorities.
To ensure better monitoring, it is recommended to measure your blood pressure once or twice a week using a monitor. To do this, you can get a device that will first check into a clinic to ensure its accuracy. At each reading, record the values obtained and to his doctor at the next visit. Once stabilized voltage can be measured less frequently.

Diet during Hypertension
It is possible to lower blood pressure by applying the following tips:
- Eat lots of fruits and vegetables;
- Limit consumption of salt: studies show that 30% of hypertensive patients (especially those that react readily with sodium) can control their blood pressure by reducing their intake of sel11. If necessary, for cooking or seasoning, replace table salt, sea salt or fleur de sel salt by potassium.
- Moderate consumption of alcohol and caffeine (up to four cups of coffee per day);
- Increase its intake of omega-3 of marine origin, mainly found in mackerel, salmon, trout, herring and cod;
- Eat garlic: although its virtues are not rigorously proven, many doctors recommend garlic for its vasodilatory properties (see Complementary).
The DASH diet
In the United States, the National Institutes of Health (NIH) recommend the DASH diet (Dietary Approaches to Stop Hypertension). This diet is specially designed to treat hypertension. It is akin to the Mediterranean diet. Research has demonstrated its effectiveness and, in the case of mild hypertension, it can even replace the usual medicines. Regular monitoring of the diet can reduce systolic blood pressure by 8 mmHg to 14 mmHg, and diastolic blood pressure of 2 mmHg to 5.5 mmHg9.
In this scheme, the emphasis is on fruits and vegetables, whole grains, nuts, fish, poultry and dairy products low in fat. The consumption of red meat, sugar, fat (especially saturated fat) and salt is réduite2, 10.

Medical treatment of Hypertension
In someone who is doing well, treatment of hypertension is to prevent damage to organs in the coming years, as the heart, brain, kidneys or eyes. When these bodies are already achieved, the treatment of hypertension is very important. In people with diabetes, the goals of treatment are higher because the risk of complications is increased.
In cases of mild hypertension, adopt habits of life, as described below, is usually sufficient to normalize the tension.
In case of moderate or advanced hypertension, the adjustment of lifestyle will reduce the consumption of drugs. A holistic approach has a more important effect on blood pressure than just taking medication.
Drugs
Several types of medicines obtained on prescription, can provide adequate control of hypertension. Here are the most commonly used:
- Diuretics, which promote the elimination of excess water and salt through the urine, there are several types that have different modes of action;
- Blockers, which reduce heart rate and force of ejection of blood by the heart;
- Calcium channel blockers, which cause dilation of the arteries and reduce the effort cardiaque;
- Enzyme inhibitors angiotensin converting, which also have an effect on dilation of the arteries, in countering the production of a hormone (angiotensin);
- Blockers, angiotensin receptor, which, like the previous class of drugs, prevent angiotensin tighten the opening of the blood vessels, but by a different mechanism of action.
The standards for management of hypertension of the British Hypertension Society supports the use of a combination (two or more medications), noting that "the majority of patients require two or more medications to achieve the standards set.

Diagnosis of High Blood Pressure
Diagnosis of Hypertension:
The doctor measures the blood pressure several times during successive visits, before establishing diagnosis of hypertension, because figures would vary considerably from one time to another. It is quite common for the voltage rises significantly when a patient enters the office of his doctor and that his power when he returns in spring. This is called the "syndrome of white coats." To avoid this type of reaction, the doctor may suggest the patient to measure his own blood pressure at home, using a tensiometer.
Once reliable values found, the doctor may diagnose a person whose pressure is equal to or greater than 140/90 have high blood pressure. Note that people with diabetes or kidney disease should ideally maintain a blood pressure that does not exceed 130/80.
Table levels of blood pressure corresponds to the following standards that determine the optimal blood pressure to 115/75 rather than 120/80. This classification applies to adults who do not take drugs to treat hypertension and who were not suffering from diabetes or renal disease.
Level of blood pressure
Note
Where the pressure measurement of systolic and diastolic pressure are two different levels, the doctor takes into account the level of the higher value to assess the state of the blood pressure.
Better understand the extent of blood pressure
Blood pressure consists of systolic and diastolic pressures, which are measured in millimeters of mercury or mmHg.
* The systolic pressure is the period of contraction of the heart and the ejection of blood into the arteries. It ensures a supply of blood across the body.
* The diastolic pressure is the pressure exerted on the arteries between each pulse, when the heart relaxes. It corresponds to the period of relaxation of the ventricles that allows cardiac chambers to fill. This pressure tends to increase with age, but went through the sixties, it gradually decreases due to the weakening of blood vessels in the body.
Blood pressure depends on the amount of blood pumped by the heart and resistance in the arteries.

Medical Description
Blood Pressure(High) also called as Hypertension, is defined by the high Pressure of Blood against the walls of arteries. It is normal for blood pressure to rise under stressful conditions or during physical exertion. In people with high blood pressure, tension remains high at all times, even at rest or in the absence of stress.
Hypertension is not a disease in itself. However, in the long term, it is an important risk factor:
* Heart failure: by imposing an additional workload to the heart, hypertension can cause depletion of the heart muscle;
* Crisis angina, myocardial infarction and stroke: high blood pressure means that the blood exerts greater pressure on the walls of arteries, which weakens and increases the risk that the artery Hangs by atherosclerosis;
* Kidney problems (renal failure) and eyes (injury to the retina can lead to a loss of sight): Once again, due to the weakening of blood vessels.
Because hypertension usually does not cause symptoms, a significant number of hypertensive patients are unaware of their condition - which is why it is called the "silent killer".
Prevalence
According to the World Health Organization, 30% of men and 50% of women aged 65 to 75 years suffer from hypertension. Today, hypertension affects populations increasingly young.
The types of hypertension and its causes
* Primary hypertension accounts for approximately 90% of cases. It is based on a multitude of factors related to age, heredity (especially for men) and harmful habits, whose effects accumulate over the years. Obesity, physical inactivity, smoking, alcohol abuse, stress and food too salty contribute to hypertension.
A high intake of salt causes water retention. According to a survey conducted by Statistics Canada, over 85% of men and 60% of women have an intake of salt or sodium than the recommended upper limit of 2 300 mg jour1. See the complete table of the maximum permissible intake of sodium.
* Secondary hypertension may result from another health problem (a kidney problem or endocrine, congenital deformity of the aorta) or the frequent use of certain medications. For example, nasal decongestants, because they contain ephedrine (a substance whose effect resembles that of adrenaline secreted under stress), anti-inflammatory drugs, which cause the retention of water and salt, and bronchodilators, which have a stimulating effect on the heart.
