About Hypertension

freezerfairy asked:


It is said that increased cardiac output may be an early feature, followed by increased peripheral resistance and normalisation of cardiac output.
The increased peripheral resistance is developed in a compensatory manner to prevent the raised pressure being transmitted to the capillary bed where it would substantially affect homeostasis.
What i don’t understand is why is peripheral resistance developed when cardiac output increased? How does this mechanism work?
And does this only apply to essential hypertension?
Thanks.

Hypertension, or what is commonly known as high blood pressure, bear upon thirty million Americans. And this figure shows no signs of shrinking; on the contrary, doctors suggest that the occurrence of this health condition will dramatically increase in the next five to ten years. There are several factors that bring about this trend, but strictly speaking, this health condition is all about bad eating habits and unhealthy lifestyle.

When you have high blood pressure, your heart is having a hard time doing its job, which is to pump blood. Under this circumstance, your heart and the other parts of your circulatory system are placed under tremendous stress. As a result, you will be more prone to having stroke, heart attacks, aneurysms, kidney irregularities, arterial disorders and even eyesight problems.

High blood pressure has always been regarded as a silent killer because it can be difficult to detect if you are already suffering from it, unless you carry a sphygmomanometer with you all the time. More often than not, this health condition provide little clue or no symptoms to alert its victims. Technically speaking though, having at least 140 over 90 mmHg (that’s millimeter of Mercury) on the blood pressure monitor means you are already suffering from the disease.

What’s really bad about having hypertension is the fact that once you have it, you have to bear with it for the rest of your life. But this is not to say that you are condemned to death. Unbelievable as it may seem, hypertension can be controlled; and when you do, you can spare yourself from all the troubles that come with this health condition. Here’s how.

Diet

Even people who do not have hypertension know that diet plays a very important role in the cause or prevention of this health condition. And it is true. If your diet is high in fat and sodium, you have an increased risk of having high blood pressure. So you better avoid food that is high in salt, sugar and fat.

But before going on a diet, you should also put into consideration your age and weight. Not all types of diet programs can be applied to everyone. It is important that your diet should not only be healthy, but somehow it should also fit your tastes and lifestyle.

Exercise

Lack of movement and flexibility can actually trigger high blood pressure because these can also cause one to become obese. Being overweight has been strongly linked to high blood pressure. Studies have shown that regular exercise can reduce the chances of hypertension by about 30 percent. You do not need to do strenuous activities to reap the benefits; even a low-intensity exercise like walking can help you attain good results

Internal Cleanse

Over time, your body will accumulate impurities that can bring about the buildup of toxins in your system. When this happens, important components of your circulatory system, such as your arteries and heart, may become blocked, lacerated, hard and even brittle. This will seriously disrupt the way that your heart pumps blood, so you will be more susceptible to hypertension.

Through internal cleansing, you will be able to flush away toxic deposits in your system. You will also be able to bring back the balance in your circulatory and other physiological functions. All in all, a toxic-free system can greatly improve your blood pressure among other benefits.

Truly, your health relies not only on the quality of the nutrients that you eat, but also on how often you cleanse your system of toxic waste products. Internal cleansing involves fasting and drastically changing old eating habits that add to the levels of toxic materials in your body. You can also use products like Colpurin to help you eliminate toxins. Visit http://www.colpurin.com/ for more details.

Alvin Hopkinson asked:


People develop hypertension or high-blood pressure for several reasons. It may be in the genes or due to a kidney disorder as well as stress related factors. The most common causes however are due to dietary intakes that result to excessive salt in our body. Excessive salt intakes will result to an imbalance between sodium and potassium that causes hypertension in our body.  

Excessive salt is quite easy to understand, but as to how sodium and potassium imbalance causes hypertension seems a bit more complicated. 

How Sodium and Potassium Imbalance Causes Hypertension

Sodium and potassium are two important electrolyte nutrients that the body uses for proper nerve functions, energy production, cell renewal, and many other bodily functions.

Salt, whose chemical composition is sodium chloride, is the main source of sodium. It is broken down as sodium and chloride during the body’s metabolic processes. Water that is not distilled also contains salt hence; water is also a source of sodium and chloride ions.

Our body cells are said to contain fluids composed of several minerals, which includes sodium, potassium, calcium, magnesium, and chloride. As studies in science have already determined, there must be a proper balance between the sodium and potassium minerals contained in every cell, for the body cells to function properly.

Some of the important cell functions attributed to sodium and potassium balance are:

• The production of acid and digestive enzymes used to break down food to provide energy for the body;

• To enable the nerves to react in terms of impulse reactions to external factors such as heat, cold, or pain felt by the body;

• To enable the heart or cardiovascular system to function properly;

Any deficiency in sodium or potassium does not result to life threatening issues, but any serious distortion or disproportion with the amount of potassium as against sodium, creates complications often resulting to heart attacks.

Imbalance results not out of potassium or sodium deficiency but mostly due to excessive sodium. Potassium deficiency on the other hand may arise from unhealthy fad diets.

When there is too much sodium in the body fluids, the kidney takes on its natural role of excreting unused or unwanted substances like sodium. However, if the amount of sodium being excreted by the kidney is beyond the kidney’s normal capacity, the problem will now arise.

Near the kidney is a vascular system or fluid carrying vessels which carry the excessive sodium and will constrict or close itself to blood flow if the kidney is slow in taking out the sodium it carries. The vascular system closes in order to increase the blood pressure near the kidney, which creates a push or force that will prod the kidney to remove the excess sodium.

Although this is a natural process, it is not a normal occurrence and may cause blood pressure to rise at a dangerous level if it will not be addressed in due time. It can be remedied by increasing fluid intakes so the kidney can have enough water to excrete sodium. The sodium excretion may have been resolved but there is now the elevated blood pressure that needs to be dealt with. 

The matter of controlling elevated blood pressure on the other hand can be remedied by using diuretic methods. The kidney took in a lot of water in order to excrete the sodium out of the system. To aid the kidney in producing more urine, a diuretic substance that can induce the kidney to produce more urine will be recommended by the doctor.

However, diuretics may also cause the kidney to excrete potassium, hence the doctor will also prescribe a potassium supplement to avoid the possible occurrence of sodium to potassium imbalance. 

Thus, the body can naturally control blood pressure by drinking more water and taking in dietary substances that can promote the process of diuretics and take care of replenishing  lost potassium. This then prevents sodium and potassium imbalance that can cause hypertension.

H. Wei Williams asked:


Qigong practitioners traditionally consider various herbs and food supplements as part of their practice of preventive health. With greater understanding of nutrition and research supporting what traditional Chinese medicine has practiced for thousands of years, it is little wonder that more and more people are turning to qigong for answers to todays’ health problems.

There are many herbs and food supplements that can treat or prevent hypertension. Here is a list of those that can significantly reduce your elevated blood pressure:

Vitamin C. A number of studies have shown 500 milligrams of vitamin C taken daily will help to lower blood pressure. However, avoid combining with grape seed extract. While there is no indication that grape seed extract reduces blood pressure, it has been found to actually induce high blood pressure when taken with vitamin C.

Onions. Added to salads and other foods, raw onions can help to reduce blood pressure in people with moderate hypertension.

Garlic. A natural antibiotic, it is antibacterial, antiviral and particularly, antifungal. Prostaglandin A, an active ingredient that gives garlic its distinctive odor, is largely responsible for reducing blood pressure and angina pain. Garlic can also act as a blood thinner and should not be taken weeks before surgery and during recovery. For best effect against hypertension, consume one or two cloves daily.

Coenzyme Q10 or CoQ10. This is a compound found naturally in our cells and is responsible for producing energy in the body. Not only does it appear to help lower blood pressure, reduce the effects of congestive heart failure, decrease gum disease when applied topically, but also reduce blood sugar in diabetics, as well as alleviate migraines and protect the brain from neurodegenerative diseases such as Parkinson. People suffering from heart failure also have reduced CoQ10 levels in their heart muscle cells.

Hawthorn berry. Called shanzha in Chinese, it is often used in Chinese medicine to treat high blood pressure and heart conditions and to aid digestion. For a reasonably low price, you can obtain a bag of dried hawthorn berries in Chinese herbal stores to make your own tea. Add hot boiling water to steep for three or four minutes. Works best with mild hypertension.

Mung beans. In Chinese medicine, they are considered yin or cold foods. In its dried, raw form, they are traditionally made into a pillow to effectively treat high blood pressure and heat or sunstroke by removing the heat from one’s body.

Folic acid. A vitamin B that is responsible for red blood cell formation, it can help to lower blood pressure in some people.

Calcium and magnesium. Make sure you get sufficient amounts of magnesium in your diet to help your body absorb the calcium. I don’t recommend cow’s milk, especially if you are lactose intolerant. Chinese traditionally get their calcium from soy milk, which I find is a far better choice.

Soy nuts. One study suggests that a daily consumption of half a cup of unsalted soy nuts will help lower blood pressure in postmenopausal women.

Ginkgo biloba. Also called bai guo or yinxing in Chinese, ginkgo nuts are often added to congee and other Chinese dishes. It protects against oxidative cell damage from free radicals, promotes blood circulation and acts as an anticoagulant. Avoid taking in large quantities — six or seven per day for three to five days is sufficient to lower blood pressure. Side effects can include increased risk of bleeding, nausea, vomiting, diarrhea, headaches and dizziness. Avoid using with MAO inhibitors or during pregnancy.

Salvia miltiorrhiza. Also called red sage or dan shen in Chinese, this herb is often used in Chinese medicine to treat cardiovascular disease and to thin blood. When slow-cooked in raw form, the effects can be long lasting, though it may take some time to work.

Chrysanthemum. Best taken as several whole flowers rather than as crystals or in tea bags. Steep in hot water for several minutes and drink a minimum of four cups daily. You can also flavor it with some raw honey to taste.

Dandelion. Excellent for hypertension and congestive heart failure, particularly in the spring when it produces mannitol that is used in the treatment of high blood pressure. You can make a tea out of two tablespoons of chopped dandelion roots and leaves by simmering and steeping in hot water. Drink 2 cups daily.

Panax notoginseng. Also called sanqi or tianqi in Chinese, it is also known as pseudoginseng. It has been used widely in Chinese medicine to treat all kinds of diseases of the blood. When ground into powder, it can be applied topically to heal bruising and sprains, and promote healing of broken bones. When slow-cooked in its raw form, it is an effective treatment for cardiovascular disease. Since it is also a blood thinner, avoid taking it before surgery and during recovery.

Always consult a physician before trying any of these herbs and food supplements. Some may be contraindicative to medications not mentioned in this article.

Beta-blockers are drugs which block the effects of adrenaline and other hormones that stimulate the heart and cause blood pressure to rise. They have been available since the 1960s and are being prescribed for a variety of medical conditions.

“Beta-blockers, which relax the blood vessels by blocking certain nerve impulses, are very versatile drugs. These agents have some 20 different approved uses or indications. Besides lowering blood pressure, they prevent anxiety and panic attacks, a boon for entertainers and public speakers; they are a mainstay in the treatment of angina, irregular heartbeats and heart attacks,” according to Dr. Isadore Rosenfeld of the New York Hospital - Memorial Sloan - Kettering Cancer Center in “The Best Treatment.”

“They control tremors; they make withdrawal from alcohol more tolerable; they’re effective in preventing migraine headaches; two of them, timolol and betaxotol, are widely used to reduce elevated pressure in the eye due to glaucoma; they are used in thyroid disorders; one is even a vaginal contraceptive,” Rosenfeld added.

When administered for hypertension, beta-blockers may be given alone or in combination with a thiazide diuretic. Unfortunately, their use here is limited because of side effects like fatigue, lethargy and impotence.

Beta-blockers appear to be more effective in young, white patients whose elevated blood pressure is caused by medium or high renin levels. This is a hormone made by the kidney which affects blood pressure.

But if that’s not your problem, you might as well forget these drugs for they won’t do you any good. Neither should they be taken if you have heart failure, asthma or heart block.

Another problem with beta-blockers is that they can decrease the blood level of good cholesterol and promote atherosclerosis, the buildup of fatty deposits in the artery walls. This increases your risk of a heart attack or stroke.

“These drugs should be avoided if you have chronic lung disease like emphysema, bronchitis, or asthma because they can induce bronchial spasm; or they can worsen matters if your heart rate is slow to begin with. They often cause impotence, fatigue, bad dreams and constipation,” Rosenfeld said. (Next: Calcium-channel blockers for hypertension.)

Sharon Bell asked:


 

The wide range of antihypertensives in the market is likely to confuse the patient. How do they differ from one another? What is the best one for you? The following guide will hopefully give you a better understanding of these drugs and make things easier for you.

Diuretics are the earliest drugs for hypertension that have been around since 1957. Many doctors prescribe them first and over 15 million Americans use them. They lower blood pressure by increasing the rate at which sodium and water are eliminated from the body.

The main advantage of diuretics is their low price. Patients don’t’ have to spend much while using them. The bad news is that they have a lot of side effects.

“One man in three who take diuretics becomes impotent. These agents often raise blood sugar (which, however, returns to normal when you stop the drug). They elevate uric acid levels in the blood, and a high uric acid causes gout so that if you’re vulnerable, you may wake up one morning with a big red, swollen, painful toe. They can upset an empty stomach (so always have your diuretic with food or milk). And then there’s the matter of voiding. Diuretics are usually taken once a day, either with breakfast or at bedtime. A morning dose will keep you ‘running’ all day; taken at bedtime you’re likely to get up every hour or so during the night to empty your bladder,” said Dr. Isadore Rosenfeld of the New York Hospital - Memorial Sloan - Kettering Cancer Center in “The Best Treatment.”

But that’s not all. While increasing the elimination of salt and water from the body, diuretics may rob you of valuable minerals like potassium and magnesium. This can leave you weak and confused.

Low potassium levels, a condition called hypokalemia, have been linked to arrhythmias or irregular heart beats. Researchers believe this was the cause of death of some male hypertensive patients in Australia who received diuretics without potassium supplementation.

On the basis of this and other findings, Dr. Hamid Ikram, head of the Department of Cardiology at the Princess Margaret Hospital in Christchurch, New Zealand said that “diuretic therapy may shorten lifespan.”

There are other ways in which diuretics can make life miserable for you. While they can effectively lower blood pressure, they do not decrease the incidence of heart attacks. This is probably because diuretics have the nasty ability of raising the blood’s cholesterol level, making the patient susceptible to heart disease.

“Statistically speaking, when, blood pressure has been lowered by a diuretic, the incidence of heart attacks is not decreased. We used to think that as long as your blood pressure stayed down, no matter what medication was used, the risk of heart attack was reduced. That appears to be true for almost every antihypertensive drug except the diuretics. In other words, when blood pressure has been normalized by using diuretics, the incidence of stroke is decreased, but not the incidence of heart attacks,” Rosenfeld warned.

“For all these reasons, I prefer not to prescribe diuretics as first-line drugs in white hypertensive patients. However, despite their drawbacks as antihypertensives, they do have an important place in the treatment of heart failure, whenever the body retains fluids and in certain ’sodium-sensitive’ forms of high blood pressure, especially common in blacks,” he added, (Next: Beta-blockers for hypertension.)

Charles Gerdson asked:


Several factors influence hypertension, however it must be fully understood that these factors change from person to person. Some people inherit high blood pressure genetically whereas others develop it from an unhealthy diet and weight gain. These hypertension causes are important to understand how they apply to each patient concerned about their blood pressure. Here are 6 main causes of hypertension found amongst most sufferers of the disease.

· Obesity. Chronic weight gain increases the chance of developing high blood pressure by 500%. A massive 2/3 of the cases of hypertension can be attributed to obesity. It is a serious health issue that is plaguing the developed countries of the world.

· Sodium Sensitivity. Sodium can increase the amount your cells release water inside your blood. This will increase blood pressure as your blood gets “thicker” or “heavier” in a sense.

· Genetics. In 30% of cases the patient has inherited the disease through their genes. This does NOT mean that the patient is untreatable, they can still practice long term lifestyle changes to combat the disease even if there are of normal health and weight.

· Drugs. Specific medications such as different forms of hormone enhancers and some anti-inflammatory drugs can play a large contribution to high blood pressure. It is up to the patient to seek medical advice concerning their drug therapy but some studies are debatable and results limited. However what I always advise people; is to stay away from using drugs if possible. Because you don’t 100% know the side affects that the specific drug will have on your body, thus to play it safe always try to seek out a more natural alternative.

So these hypertension causes are to be taken into account when planning your blood pressure management. Each cause is preventable and if you feel like you have tried everything don’t give up. There are numerous alternatives to just medicinal drugs, the easiest alternative is to be as healthy as you can be, being the right weight and eating healthy plus exercise is the first step to healthy blood pressure levels.

How To Administer Cpr

Mitamins Team asked:


High blood pressure, also known as hypertension, is often considered a modern day disease. Everything about the modern, fast-paced, American lifestyle seems geared towards elevating our blood pressure. Some of the causes of high blood pressure such as smoking, obesity, and excessive alcohol consumption, are more easily dealt with. All it requires is a few small lifestyle changes and a bit of willpower. But other causes, such as a stressful job, city pollution, and family history, appear to make hypertension almost inevitable for some.

In addition, other diseases affecting the kidney or adrenal gland can be a cause of high blood pressure. Certain steroid based medicines also increase blood pressure and can lead to hypertension. Whatever the cause of high blood pressure, the results are the same: your heart is put under more pressure and has more work to do. This increased workload can lead to heart disease, heart attack, and stroke.

Many high blood pressure treatments seek to eliminate the causes of hypertension but as we’ve seen, many of the causes of high blood pressure are not so easily avoided. If we live in a smoggy city to make a living, then that’s where we live, and there is little we can do. An alternative high blood pressure treatment is to increase the heart’s capability to deal with the external factors that cause hypertension. In both cases blood pressure decreases, the only difference is that one method doesn’t mean a complete lifestyle overhaul.

An overworked heart needs more energy to perform its functions and this is where Co Enzyme Q10 (CoQ10) comes in as a treatment for high blood pressure. If the key to lowering blood pressure is giving up your high-paid job and retreating to a Tibetan monastery, then the back door key to high blood pressure treatment is CoQ10.
