High Blood Pressure
Importance Of Exercise In The Control Of Blood Pressure
Is shown that frequent physical exercise can lower blood pressure in a person with hypertension?
Yes, recent studies have shown: 1) that in people with hypertension, after a session of physical exercise dynamic of moderate intensity (brisk walking , jogging, bike ride without hills, gentle swimming, …) that lasts for 30 to 45 minutes, a decrease from 10 to 20 mmHg in systolic blood pressure during the 1 to 3 hours, and this response can be extended to 9 hours, and 2) that in people with moderate hypertension (140 – 180 / 90 – 105mmHg) can be seen after several weeks of physical training, an average decrease of 8 to 10 mmHg in systolic and 5 to 8 mm Hg diastolic blood pressure at rest.
Is that improvement in blood pressure observed in people with moderate arterial hypertension, occurs equally in people with normal tension or in those with high tension?
No. In general, the decrease in blood pressure with exercise training is greater the higher the blood pressure of the subject. In other words, people who have severe hypertension improved more than those with moderate hypertension, while those with normal blood pressure decrease your blood pressure very little sleep, but avoid the increase of the tension observed with age in sedentary people.
If physical training is a good treatment for hypertension, you do not take medicine against stress when deciding to exercise so often?
In the case of moderate hypertension (140-175 / 90-105 mmHg), the positive effects of the training program are similar to those produced by the commonly prescribed medication, with the difference that exercise training is accompanied by an improvement in other risk factors, as has been observed that treatment with medication against hypertension can worsen other risk factors. For this reason it is preferable for people with moderate hypertension treatment chosen as the physical training program instead of medication, especially since you are wondering whether they should be treated with medication or moderate hypertension. In the case of people with severe hypertension (resting values at or above 180 / 110 mmHg), it is recommended to take medication against hypertension and also to make a fitness program tailored to their physical condition because in this case only the treatment through physical activity is not enough to lower blood pressure to normal. When combining these two treatments in severe hypertension, there has been a decrease in mortality and, eventually, a reduction in medication dose.
Fighting high blood pressure with exercise
One of the focal points for a good treatment for hypertension or high blood pressure, is the physical exercise. In fact, some doctors place to exercise as part of the requirement that grant medical patients, a drug like more.
In fact, a pace that regular exercise can make blood pressure go down a point. For example, decrease of 16-10 to 15-9 once the body gets used. This is because the heart is accustomed to work better after each session of exercise, especially of the aerobic.
This improvement can be explained in several ways. By training the heart muscle, it will be able to mobilize more blood with fewer beats per minute, so that the pulse will decrease and the heart will tire less quickly. In addition, arteries coronary, which are responsible for nourishing the heart, dilate better and allows an improvement of the entire circulatory system.
There are other benefits that so indirectly improve the health of the circulatory system and the body in general. The main benefit is weight loss can be achieved, especially if combined with a healthy diet . Exercise also results in decreased levels of cholesterol which benefits the arterial circulation.

Vitamin E and High Blood Pressure
Many people with high blood pressure has significant levels under mind ¬ vitamin E in their bloodstream, compared with individuals with normal blood pressure. This could be because those with good amounts of vitamin E are able to protect themselves from damage to the arteries that causes high blood pressure. Those who do not have this protection have an increased risk of developing this condition.
Vitamin E is known for its effect as thinning the blood, preventing dangerous blood clots and helping the arteries to relax. (Although some scientific studies and some individuals have shown a ¬ strated that vitamin E may help reduce blood pre sion, this has not been established by the FDA.)
Side effects: potential side effects of vitamin E include weakness, headache and nausea.
Hypertension
Hypertension or high blood pressure occurs when the arteries are contracted or narrowed thus increasing resistance to blood flow through them. This makes the heart work harder to pump blood forcefully to start their journey through the body. If this condition is maintained for long periods can result in damage to the heart and arteries. It also increases the risk of stroke and heart failure, stroke (stroke), and kidney damage.
One characteristic of hypertension is usually causes no symptoms until there is a serious problem that can even be life threatening. For this reason hypertension is known as a silent murderer. When these symptoms may include nosebleed, arrhythmias, headache, blurred vision, dizziness, and tinnitus (abnormal sounds perceived in the ears or head). These symptoms usually occur only in severe cases. In diabetic patients blood pressure greater than 130/80 should be considered a risk factor and should be considered treatment.
Hypertension affects millions of people. Until the age of 55 more men than women with hypertension. However, thereafter the women begin to experience more of it than men. African-American descent People with this condition suffer more than other ethnic groups. Read the rest of this entry »

For hypertension, reducing salt intake is not sufficient
In an analysis certainly add fuel to a long debate about the impact of salt intake on health, a group of researchers found no evidence that moderate use cuts reduce the risk of developing heart disease or premature death
A systematic review published by the Cochrane Library , British scientists discovered that while reducing salt intake leads to seemingly minor reductions in blood pressure, that does not translate into a lower risk of death or heart disease.
Investigators said they suspect that the tests performed so far were not large enough to demonstrate any benefit to heart health, they proposed to do larger studies.
“With governments setting targets for even lower intake of salt and companies trying to remove their products is really important to do larger trials to understand the benefits and risks of reducing the use of salt, “said Rod Taylor, Peninsula College of Medicine and Dentistry of Exeter University, who led the review.
Most experts agree that eating too much salt is bad for your health and reduce their use may reduce high blood pressure in people with normal and high. But researchers have yet to demonstrate whether the benefit to the pressure results in better heart health in the general population. Read the rest of this entry »

Control your blood pressure with Chocolate
The chocolate helps lower blood pressure and prevent cardiovascular disease. A couple of ounces a day would be the ideal amount. A higher proportion of cocoa, the more health benefits. 03.04.2010 – 24:11 There were also signs that its consumption was beneficial for controlled heart. That asegurabanen 2008 in a study by scientists at the Catholic University in Campobasso, in collaboration with the National Cancer Institute of Milan. As a team of German researchers from the Institute of Human Nutrition and Nuthetal corroborates what the Italians noted: chocolate helps reduce blood pressure and prevent cardiovascular disease.
The research results were published in the latest issue of the journal European Heart Journal. 7, 5 grams daily chocolare reduced by 27% the risk of cardipatías and strokes by 48% According to this study, people consuming an average of 7, 5 grams of chocolate, the equivalent of a couple of ounces of standard tablets have a 27% lower risk heart disease and 48% lower risk for stroke, while his blood pressure was between 1 and 0, 9 mm Hg lower than in the rest. The study analyzed the eating habits of a total of 19,357 people between 35 and 65 who were followed up 10 years in which they were asked how often they ate a chocolate bar of 50 grams or two or half a case by case. In addition, a small group of about 1,500 participants were asked to specify the type of chocolate they consumed, ensuring that 57% took it with milk, 24% black and 2% white, although these data have not been considered for the final conclusions. However, researchers believe that cocoa flavanols may be responsible for this positive effect on blood pressure individuals, so the chocolate with more cocoa percentage would be to contribute the greatest advantages. Furthermore, Buijsse warned people to be careful when eating chocolate as “small amounts of chocolate can help prevent heart disease only if they replace other foods rich in energy, as a snack, to maintain a stable body weight”.

Consequences of Hypertension
The heart is the most important muscle in the body, its main function is to pump blood to the lungs and the rest of the body is a hollow organ that receives blood from the veins and pushes into the arteries. Is supplied by the first two branches of the aorta, which are the left coronary and right coronary arteries.
The heart pumps blood through a network of arteries, veins and capillaries. The moving blood pushes against artery walls and this force is measured as blood pressure.
Blood pressure readings measure the two parts of pressure: systolic and diastolic pressure. Systolic pressure is the force of blood flow through an artery when the heart beats. Diastolic pressure is the force of blood flow within blood vessels when the heart rests between beats.
Hypertension is the increase in blood pressure chronically. It is a disease that has no symptoms for a long time and, if untreated, can lead to severe complications such as myocardial infarction, cerebral hemorrhage or thrombosis, which can be avoided if properly controlled. The first consequences of those suffering from hypertension the arteries, which are hardened to withstand as high blood pressure continuously, thicken and may be difficult to pass blood.

What is the Cause Of that Raise Blood Pressure?
Various circumstances can cause increased blood pressure:
• Thinning of the arteries. Some circumstances may cause the arteries to lose weight, including the accumulation of a fatty, waxy substance called plaque, nerve messages and the inner wall of the damaged arteries. When arteries become thinner and forces the heart to pump more blood to send to the body.
• Overweight. The fat needs blood, just like any other body tissue. Each kilo of fat contains perhaps half a mile of blood vessels, which must be filled constantly with blood. Your heart has to work hard to bring this blood supply throughout the day.
• emotional upset. Anger, excitement, fear and other negative emotions can trigger extreme responses (fight / escape) and make your heart work a forced pace.
• physical stress. Pain, heat or extreme cold and other stresses, can accelerate the heartbeat too.
• Smoking cigarettes. The substances in cigarettes accelerate the heart rate while thin arteries.
• Pregnancy. The extra blood and increased blood vessels can increase blood pressure of the mother.
• damaged arteries. The inner walls of the arteries may become inflamed or hardened responding poorly to the demands of the body enlarged or reduced as appropriate to the situation 10.
• Obstruction of the arteries. The accumulation of fat known as atherosclerosis can cause the arteries to become thin or become hard.
• Blood clots. May form a mass of clotted blood and stick to the walls of the arteries or a piece of plate and interfere with blood flow.
• Some diseases. Hyperthyroidism, kidney disease, and many other conditions also can cause elevated blood pressure.
What Is High Blood Pressure?
High blood pressure is a serious condition that you wanted to avoid at all costs. If you practice good health habits, there is a high probability that you can maintain control this condition.
Although we can not touch, see or feel, high blood pressure, known by doctors as hypertension, is a common and potentially serious condition. Nearly one in three adults has high blood pressure. It is an alarming rate. The situation becomes more troubling when we know that only 65% of those who have it, you know, and also only 30% are being treated properly and have the problem under control.
Blood pressure is written as a fraction and the number is considered normal is 120/80 or less. The top of the fraction measures the pressure exerted on the arteries when the heart beats. Also known as systolic pressure. The bottom of the fraction (80), measures the pressure in the arteries between heartbeats. It is known as diastolic pressure. You want both numbers are within the normal level.
• Readings of 120/80 or less is optimal.
• readings between 120/80 and 140/90 are within the warning area for high pressure.
• readings over 140/90 are considered high pressure.

What If My Pressure Rises Too?
That might think high blood pressure sounds as positive, as a sign that blood is flowing rapidly through the blood vessels. Unfortunately, the blood vessels are designed to withstand a certain amount of pressure. A higher pressure may be harmful to the vessels and other body parts.
Here I will mention some body parts that could be affected by high blood pressure:
• Arteries. Excessive blood pressure can break the walls of the arteries, facilitating the formation of plaque and hardening of the arteries. Excessive pressure can also weaken an artery so that part of its encompassing wall outward. If the outer bag will begin to be watered, your blood may flow into your body tissues. If this happen in your brain, called cerebral infarction. If it happens in your heart called aortic aneurysm. Either scenario is so dangerous that can lead to death.
• Heart. If the heart has to work hard just to keep the blood circulation, may tire, weaken and eventually fail. High blood pressure may allow the filling of the arteries in the heart muscle itself, leading to a heart attack.
• Brain. High blood pressure can weaken the arteries in the brain or those that carry blood to it and result in stroke. You can also contribute to another type of stroke caused by blockage of an artery that feeds the brain.
• Kidneys. High blood pressure may promote the filling of the arteries that feed the kidneys, making them less efficient and probably causing kidney failure. And because the kidneys help regulate blood pressure, any damage suffered, could send your blood pressure out of control.
