Risk of heart attack or stroke when blood pressure is too high
When blood circulates too fast excessive pressure (as if hit on the walls of the veins that circulate) and when that happens …
The heart “enlarged” and increases muscle mass (the doctors call left ventricular hypertrophy). When not at the same time produces an increased blood flow may appear coronary insufficiency and angina pectoris. One symptom of this is happening is that more arrhythmias suffer no apparent reason.
More risk if hypertension is nocturnal. Lately, doctors emphasize that people with high blood pressure is also measured with the night, because when there is high at this time there is more risk of suffering a heart attack or stroke.
High blood pressure is hardening of the arteries, which favors the accumulation of cholesterol and other fats and can facilitate an artery to rupture and cause a brain hemorrhage.

Fluid retention
The main cause of renal failure is high blood pressure. High blood pressure forces the kidneys to work harder to work, and when blood vessels are damaged, the most common is that the body retain water and therefore we feel swollen in the abdomen, hands and ankles. Fluid retention with blood pressure tends to rise even more, and if the situation continues over time, that kidney damage can feed some degree of renal impairment.
The eyes are suffering and damage
High blood pressure and maintained over time can cause the arteries and veins of the retina be narrowing, which can cause small hemorrhages occur in the eye and cause what is known as hypertensive retinopathy.
High blood pressure can also cause hemorrhagic injury to the optic nerve, is called neuroretinopathy , producing a localized collection of fluid, sometimes also micro-hemorrhages.
In both cases, you may notice blurred vision, and in the most serious, may occur as some kind of blindness.
Senile dementia is associated with hypertension
Having well-balanced blood pressure, and ensure heart health, also contributes to the brain.
A study by the University of Pittsburgh (USA), ensures that hypertensive women are the most likely to suffer dementia, and that hypertension leads to abnormalities in brain white matter.
In elderly people with low blood pressure is that may cause some cognitive impairment, especially if you also have heart failure.
Weakness, tiredness and excessive daytime sleepiness
Low blood pressure can cause a range of symptoms: difficulty concentrating and memorizing, skin cold and pale, sweating, breathing fast and shallow, and even prone to depression, which may cause the person to have a very low pace of life .
Hypertension can also cause weakness because the body does not maintain adequate blood flow, plus it may indicate heart failure.
Frequent dizziness and loss of consciousness
It is common for people with low blood pressure experiencing dizziness. Most of the time, the situation is a simple dizziness, but is useful to know how to prevent it or what to do at that time not to suffer a fall and a possible hit with major injuries.
When a syncope or a total loss of consciousness occurs because not enough blood supply to the brain. Usually, the person regains consciousness within a few minutes.
Such symptoms may be caused by high blood pressure, and usually happens when the disorder is not well controlled or if it does not take the medication that the doctor has recommended.

Healthy recipes and home remedies for hypertension
Hypertension is a widespread disease in our society.
According to several studies, a decade two adults have problems with your blood pressure and in the U.S., according to recent figures from the National Center for Statistics Health, Is the third chronic illness, after sinusitis and arthritis.
When there is high (more than 130 over 85), the blood circulates with excessive force in the arteries which can cause rupture of small arteries or hurting sections of arteries. This situation can lead, over time, stroke, heart failure, heart attack or stroke.
It is important to note that hypertension is a disease that can be present for years without showing any visible symptoms until they encounter a serious health problem as mentioned above.
Food plays an important role for hypertension, both for the care that must be taken with certain foods such as the systematic use of others we can help reduce that pressure.
Here are some beneficial nutrients in the fight against hypertension:
Foods to Fight Hypertension
Grapefruit All citrus, especially grapefruit, contains a vasodilator. At consume at breakfast, grapefruit has a relaxing effect on the artery walls causes low tension.
Brown rice. Its ingredients facilitate relaxation of the artery walls and lowers blood pressure. Therefore, it is recommended in the diet of3 to 4 courses per week of this type of rice.
Green peppers. Among the ingredients of green peppers can be found certain vitamins that relax the walls of the arteries, as well as strengthen them. For that reason, we recommend add them in salads and other similar dishes.
Olive oil. With this type of oil can improve the condition of the walls of arteries and also to treat hypertension can prevent and treat atherosclerosis. From there it is recommended to include a little olive oil first pressure.
Home remedy for hypertension
Put in a container, three cloves of garlic in a quart of water, cook and drain the contents. Save the liquid in a container. Drink a glass every day.

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.

Increased blood pressure during exercise
The nervous system plays an important role in increasing the body’s blood pressure . One of the most significant examples is when there is increased during muscular exercise.
During intense exercise the muscles need a lot of much greater blood flow . Part of this increase is due to local vasodilation of the muscle vasculature caused by increased metabolism of the myocytes (muscle cells).
Other increases occur as a result of elevated blood pressure sympathetic sympathetic stimulation caused by the circulation during exercise overall. In the more intense exercise may increase blood pressure by 30% -40% , which increases blood flow almost twice more.
The increase in blood pressure during exercise is due mainly to the following effect: while the motor areas are activated to initiate the exercise brain also activates most of the reticular activating system of the brain stem, including stimulation much greater vasoconstrictor and cardioaccelerator areas of the vasomotor center. This increase in blood pressure is a snap to maintain synchronization with increased muscle activity .
Are many other types of stress also produced a similar increase in pressure . For example, during the intense fear of blood pressure can increase up to twice normal in just a few seconds, which is known as alarm reaction.
Exercise: a way to lower your blood pressure
Bad news
There are three “bad news” about high blood pressure (hypertension). First, any increase in blood pressure increases the risk of having a heart attack, but this does not mean you will have a heart attack. Second, there are more than 50 million Americans with this important medical condition, and one in two people over 60 high blood pressure. Third, many men and women do not even know they have high blood pressure because they just have symptoms, especially in the early stages.
Good news
If you already know you have high blood pressure and is an important first step. There are different ways and easy to control your blood pressure and therefore reduce their risk of stroke. Mortality rates for heart attacks in the U.S. have declined by 40-60% over the past 20 years, partly due to more effective control of blood pressure.
Your Choices
Your choice of trying to lower blood pressure and use physical activity as part of your treatment depends on how high is your blood pressure. If you have a blood pressure (systolic value greater than 180 or diastolic value greater than 110), treatment should be by medications. Once your blood pressure is under control, physical activity can lower your blood pressure even more. Exercise can also decrease the need for medications, but usually not completely eliminated. You should contact your doctor before starting a physical activity to be sure of exercise recommended for you. Currently recommended as initial therapy for people with small or mid-rises in blood pressure change (3 to 6 months) in lifestyle towards healthier behaviors – including physical activity, decreasing the salt in foods, and losing but -. However, you should consult your doctor to be sure that these recommendations are applicable to you. Read the rest of this entry »
Diet for high cholesterol and hypertension
Both high cholesterol and hypertension are risk factors threatening cardiovascular health. From food, it is possible to counteract this situation to develop a diet special, which contains a selection of foods appropriate for both lower cholesterol and high blood pressure.
Abnormal levels of blood cholesterol can result in major cardiovascular problems, if this is added hypertension (blood pressure values greater than 70/140 mmHg), the situation could deteriorate further.
Since power can provide an answer to this situation through a special diet for hypertension as well for high cholesterol .
Food choices to lower cholesterol and blood pressure
Milk: Skim.
Yogurt: Skimming.
Cheese: Reduced-fat and sodium, and spreads are as tight. Avoid hard cheese ripening or large (contains too much fat and sodium).
Egg: Whole no more than 3 times a week. Egg every day.
Meat sea fish, chicken without skin or fat, beef fat or similar visible.
Vegetables: All preferably raw. Choose those containing a high potassium content: tomato, spinach, squash, carrots, beets. Read the rest of this entry »
Hypertension
Blood pressure is simply the amount of force exerted when the blood pushing against blood vessel walls. High blood pressure, or hypertension, is when there is too much pressure on vessel walls, which makes the heart work too hard to push blood through the arteries narrower. Over time, high blood pressure weakens the heart and causes hardening of the walls of the arteries, making them weaker and more susceptible to injury. Often, high blood pressure has no symptoms of any kind, but this damage to blood vessels or the heart can cause stroke, heart failure, myocardial infarction, renal failure, and loss of vision. This is why hypertension has the infamous nickname “the silent murderer” ( 1 ).
Have you heard that reducing sodium can lower blood pressure? Well, that’s true for many people ( 2 )! Sodium is found in many foods in small amounts but constitutes about 40% of table salt. It is necessary for the body in very small amounts, but most Americans eat too much. So how sodium increases blood pressure?
Sodium is always in solution in the body, so it passes through the digestive tract, blood vessels, it carries fluid. Normally, the vessels are quite elastic, as the walls of a balloon. However, excess fluid in sodium increases blood volume. As if we added water to a balloon, this makes the diameter of the vessels to stretch and makes the vessel wall is tense with the pressure. Over time, this increased pressure within the arteries can cause hardening of the walls of the arteries and lead to permanent damage.
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 »

High blood pressure
The frequency (22% of the adult population suffers from it), the serious impact caused in the health of those affected and the high cost of treatment and the complications that justify the relevance of results in hypertension.
The circulatory system has the heart (engine throws the blood), the arteries by circulating blood and distributed, the capillaries (facilitate the exchange between blood and tissues) and veins that collect blood once used and return it to heart. Blood flows with a pressure or tension, depending on how hard the heart and the driving resistance that oppose the arteries occurs as with the water that comes through a hose, if you open the faucet or clamped the hose, the water pressure rises.
There is a maximum pressure, systolic or high, which coincides with the heart’s contraction, and a minimum pressure, diastolic, or lower, with the cardiac relaxation. It is difficult to establish normal limits. Have been established for adults, based on the risk of developing complications, and are accepted internationally (see table).
