What Is Healthcare?

March 5th, 2010

The expression health-care is the provision of medical facilities plus the general prevention and management of illness using professional medical resources. The World Health Organizations definition is a little different and refers more to the prevention of sickness and facilities to encourage this, in addition to intervention that should be available to a single person as well as a whole population. The organized provision of such facilities may constitute a health care system.

Early before the phrase health care was popular, the English speaking countries called it just plain medicine or more usually the health sector but it still meant the provision of a health service to treat and cure sickness and disease. Around the world today, most countries have a system in place to ensure that everyone receives healthcare irrespective of their social standing or financial situation. This first begun in the United Kingdom a few years after the end of World War 2 in 1948, and became the first healthcare service set up and run by a administration.

Alternatively a system of compulsory government funded health insurance with nominal fees can be provided, as with Italy, which, according to The World Health Organization, has the second-best health system in the world. Canada and Australia have both started similar systems and have been running since 19.6 and the 1970’s respectively both going by the name of Medicare. general health care contrasts to the systems like healthcare in The USA or South Africa, though South Africa is one of the many nations attempting health care reform. Individuals who work in health care include all professionals whose job it is to preserve life, treat and cure illness and try to better the health of people. The collective expression for this is the health care industry but the word industry may not necessarily be the best one to use.

The health care industry is one of the world’s largest and fastest-growing industries generally consuming at least 10 percent of gross domestic product of most developed nations, healthcare can form an enormous part of a country’s economy. The only world nation to differ is The USA with over 15 percent according to figures published in 2003 but it is set to rise to almost twenty percent by the year 2016.

High Blood Pressure - Are You At Risk?

February 27th, 2010

When your heart pumps blood, pressure is exerted against the walls of the arteries, prompting the term “blood pressure“. While your heart is actively pumping blood, your blood pressure is at its highest, referred to as systolic pressure. When your heart is at rest - between beats - your blood pressure falls, this is diastolic pressure. These two numbers are used to determine your blood pressure with the systolic pressure being placed ahead of the diastolic pressure and written one above or before the other, such as 120/80 (normal). Both of these numbers are important. Any reading above 120/80 places the body at risk, the higher the pressure, the greater the risk.

Hypertension (high blood pressure) is a chronic ailment in which the blood pressure (BP) reading is constantly 140/90 and above. If this pressure rises and remains high for a prolong period it can cause serious damage in the form of: stroke, heart attack, heart failure, arterial aneurysm or kidney failure. Signs of prehypertension are 120 and 139 for the top number, or between 80 and 89 for the bottom numbers, this is a precursor to high blood pressure and immediate steps should taken to prevent the more serious condition.

here is a two pronged approach to providing treatment for this disease. They are: medication and self care. In situations where the illness is due to the existence of another disease, the high blood pressure will be alleviated once this primary disease is treated. For sufferers of secondary hypertension there are a variety of prescription drugs available: diuretics, beta blockers, calcium channel blockers, angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers.

• Diuretics (Water Pills) – Recommended as the first line of treatment, this medication works on the kidneys to help rid your body of sodium and water thus reducing blood pressure.

• Beta blockers – They reduce the effects of excitement and physical exertion on the heart and opens the blood vessels. The heart then beats slower while exerting less force.

• Calcium Channel Blockers - these dilate the arteries thereby reducing the amount of pressure exerted on them, putting less strain on the heart.

• Angiotensin-converting Enzyme (ACE) Inhibitors - Angiotensin II is a chemical produced in the blood which causes the muscles surrounding blood vessels to contract. The inhibitors restrict this activity allowing the blood vessels to enlarge.

• Angiotensin II Receptor Blockers – This medication is similar in function to ACE inhibitors. It prevents angiotensin II from binding to angiotensin II receptors on blood vessels allowing the vessel to enlarge.

Asthma attacks and what to do when they strike

February 11th, 2010

Asthma attacks are the result of a constriction of the muscles of the air passages, the swelling and inflammation of the air passage linings, and the production of phlegm that is denser than normal, the net effect being shortness of breath and coughing. During asthma attacks people will exhibit signs including restricted rapid breathing denoted by severe wheezing, incessant coughing, retractions caused by constricting muscles in the chest and neck, panic and anxiety, restricted talking ability, sweaty and pale faces, and blue lips or fingernails. Asthma attacks can either be mild or severe. The former types are experienced more often and the air passages tend to clear within a few minutes or hours. Severeasthma attacks are indeed serious and will often necessitate medical attention lest they become fatal.

Asthma attacks can be anticipated by virtue of the warning signs exhibited well before an incident occurs. Taking heed of these signs is most advisable since ignoring them can only be equated to intentional flirting with death. Some of the most pronounced signs of impendingasthma attacks include a reduction in peak flow meter readings, regular coughing mostly at night, a tendency to lose breath or have a shortage of it very easily, extreme fatigue and weakness during exercises or workouts, and a sustained exhibition of symptoms characteristic of allergies and colds, (e.g. headaches, runny nose, sneezing, coughing, and nasal congestion), etc.

As has been noted, to preempt you need to pay attention to the symptoms listed above. Each asthma-affected person has individual pending attack characteristics and this should prompt such a person to get a thorough understanding of his/her asthma symptoms, attack frequency, and how to react. The aforementionedpeak flow meter readings are an integral part of this self-monitoring task and these give a helpful bearing on what should be done.

Why Vegetarians and Vegans Have Better Prostate Health

February 9th, 2010

Here is another good reason for men to consider a vegan or a vegetarian diet, certain foods, especially soy derived products and fruit can help support men’s prostate health. Both soy derived products like soy milk, soy burgers and fruits are common ingredients in vegetarian and vegan diets. It is not necessary to chose a vegan or vegetarian diet to enjoy better prostate health by eating these foods, they can be incorporated into any eating plan.

The fear of prostate cancer or an enlarged prostate is a very real fear for many men. The idea that certain foods may be beneficial to maintaining good prostate health is very good news. Soy products and fresh fruit are widely available and they offer a wide variety of healthy benefits. They are also low in calories and nutrient rich.

Prostate health, or the lack of it, can influence a man’s sexuality. Poor prostate health can cause men to turn to medications like Viagra to help them reach their optimum performance. A prostate healthy diet rich in soy derived products and fresh fruits can eliminate the need for such medications.

Vegans and vegetarians have long known the benefits of these healthy foods, now it’s time all men take advantage of soy products to maintain a healthy prostate.
