In the year 2000 it was estimated that about 25 percent of people worldwide had hypertension and this number is expected to keep rising further increasing the risk for millions in developing cardiovascular disease. There are two main types of hypertension. Secondary hypertension is caused from an underlying disease in the adrenal or renal systems or by use of certain medications. It is resolved when the cause is treated or removed. Primary or essential hypertension is the most common type with the cause being unclear although the incidence is higher with age and weight.
Pathophysiology
The amount of blood the heart pumps and the amount of resistance the arteries have to blood flow determines the blood pressure. High blood pressure

Although both of these readings are important after the age of 60 the systolic reading is more significant due to the association with cardiovascular disease. Two to three blood pressure readings will be taken at separate appointments before a diagnosis of hypertension can be determined.
Although the causes of essential hypertension are unclear a number of factors have been known to increase blood pressure. Changes either from genes, behavioral, or the environment which disrupt the normal functions of the body may cause a rise in blood pressure. Other factors that increase blood pressure are kidney fluid and salt balances, the renin-angiotensin-aldosterone system, sympathetic nervous system activity, and blood vessel structure and function (Bolivar, 2013). Since blood pressure homeostasis is accomplished by multifactorial mechanisms if there is a change in one of these mechanisms another attempts to correct this change in order to maintain a normal blood pressure. When this system fails and blood pressure can no longer be normalized by this method than essential hypertension results.
The kidneys regulate the body’s salt balance by retaining sodium and water while excreting potassium. Any imbalance in the kidneys function will expand blood volumes causing blood pressure to rise. The renin-angiotension-aldosterone
Hypertension, also known as high blood pressure, has become a major risk factor for several types of heart disease across the globe. In the United States alone, nearly 70 million adults have been diagnosed with this condition [1]. Hypertension is a condition in which arterial walls experience extreme force from blood flowing through; long-term force against artery walls will lead to more serious health problems such as stroke, renal failure, and other cardiovascular diseases [2]. If the proper steps to treat hypertension are not taken, patients have a high risk of developing atherosclerosis, a condition that causes arteries to harden significantly. Smoking, obesity, lack of physical activity, high alcohol consumption, and high sodium intake are factors that may cause an individual to be diagnosed with hypertension [3] Detection of hypertension is crucial in order to reduce the incidence of death by cardiovascular disease [1].
Being held by your word because you make a promise, or commitment is frustrating and tough. You don’t always want to do what you promised because it could be hard, or get you into trouble. Throughout the book Hotel on the Corner of Bitter and Sweet, Henry and Keiko’s relationship comes at a cost. They make commitments that comes with sacrifices which makes them hard to keep. Through Henry and Keiko’s relationship Ford shows that commitment is difficult.
As the blood is forced throughout our body, there is a pressure that is exerted on the walls of our arteries, this is known as blood pressure. We see blood pressure represented as two numbers, the systolic (top) and the diastolic (bottom) numbers. The systolic blood pressure is the heart contracting and the diastolic is the heart relaxing. A normal, healthy, blood pressure would be written as 120/80 mmHg (millimeters of mercury) or verbally expressed by most individuals as 120 over 80. Our blood pressure can vary depending on many things. When the diastolic or systolic pressure is high, or significantly and consistently above 120/80 mmHg, this is what we call hypertension. There are different stages or degrees of hypertension. Lippincott Williams and Wilkins (2010) describes the stages as the following:
Hypertension is a very common problem, affecting 1 billion people worldwide, with 50 million cases in the United States, and one third of cases going undiagnosed. 1% of the cases will experience a hypertensive emergency in their life. (1,2)
The general herpes virus has become very common in society today. However, there are many treatments to cure this virus, such as Acyclovir(Zovirax) and Valacyclovir(Valtrex). Although these treatments cannot completely cure this virus, it will prevent the spread of cold sores, genital herpes, chicken pox, and shingles. Even though there are plenty positives for these two drugs, unfortunately, there are irritating side effects for taking them; for example, some side effects of Acyclovir can be nausea, diarrhea, dizziness, and vomiting. On the other hand, side effects of Valacyclovir contains more severe symptoms such as bruising or bleeding, bloody diarrhea, and red spots on the skin. About forty-five million people of the United States over the age of twelve have been infected with HSV-2, or Herpes Simplex Virus, and deal with these symptoms(WebMD).
There is a complex interrelationship among the cardiovascular system, the central nervous system (Na+, appetite and thirst regulation), the kidneys, and the tissue capillary beds distribution of extracellular fluid volume). Any change at any of these sites affects the function at other sites. There is a basic law of kidneys that Na+ excretion is directly proportional to mean arterial blood pressure (MABP). A marginal increase in MABP causes significant increase in Na+ excretion.
The major health problem selected for this project was hypertension (Harrison et al, 2011). It is identified as a cardio vascular disease risk factor such as dementia, chronic kidney disease, coronary heart disease, and stroke (NICE, 2011). It can be missed easily, as in various instances it is asymptomatic as well as it is also known as a silent killer. The Hypertension is thought to be a disease of vascular regulation ensuing from arterial pressure control mechanisms malfunction (extracellular fluid volume, rennin-angiotensin-aldosterone system, and CNS) that results in elevation of BP by means of enhanced peripheral vascular resistance, and cardiac output. There are 2 basic hypertension types. Around 90 to 95 percent of the individuals have primary hypertension which is linked with change in lifestyle as well as needs medical treatment. On the other hand, 5-10% has secondary hypertension which is linked with various other diseases for instance pregnancy, thyroid, and renal (Haslam and James, 2005). It is estimated that around 1 in 20 adults will have increased BP of 160/100 mmHg and above that results in either more than one predisposing aspects (Gemmell et al, 2006).
If diabetes is not diagnosed at an early stage, individuals will not notice the presence of the symptoms until they experience trouble with their heart, brain, kidney, and etc. Therefore, it is always best to speak to a health care provider or ones doctor regarding hypertension. In 2009, Americans visited their health care providers more than 55 million times to treat their high blood pressure. (Roger, Lloyd-Jones, 2012). One can also prevent the risk of hypertension by exercising regular, maintaining a healthy body weight, and avoiding heavy salt intake and excess alcohol use. Treatment is also available for hypertension. Various drugs like diuretics which work on the kidney to flush out excess water and salt from one’s body, beta and
Pre-hypertension is 120 to 139 systolic or top number blood pressure, 80 to 89 diastolic or bottom number of blood pressure 3. Hypertension is characterized as anything over 144 systolic and anything over 90 diastolic III. Blood pressure basics A. The body 1. In order to survive and function properly, your tissues and organs need oxygenated blood that your cardiovascular system provides, when heart pumps it pushes blood though network of vessels 2.
Hypertension is a common health problem especially among people over age of 60 years. This disease is diagnostic when a patient blood pressure is more than 140 to 159 over 90 to 99. Blood pressure refers to the pressure that blood applies to the inner walls of the Diabetes is an endocrine system disorder that occurs when the body is unable to control or balance the amount of sugar in blood and within bodily tissues. You know that the human body is like a machine, with organ systems that are specialized in certain functions, and interact with each other to allow all vital functions to happen. For the body to stay healthy, it is essential that its internal environment is stable and balanced despite the different changes that can occur inside
Essential hypertension is high blood pressure that does not have a known cause. Blood pressure is the force of blood against your artery walls as your heart pumps blood through your body. Hypertension occurs when the force of blood is too strong.
Hypertension is widely considered to be one of the most important risk factors of cardiovascular diseases (angina, arrhythmia, etc.). It is the second leading disease that causes mortality in the world. Hypertension is the condition when there is an increase in the force of blood on the walls of vessels. It can also be defined as an arterial blood pressure that is raised above 140/90 mm Hg (systolic/ diastolic BP). Hypertension can be classified into Secondary hypertension and Essential hypertension. When specific cause is evident but heredity, and various physiological parameters play a role in increasing blood pressure is known as Essential Hypertension. Secondary Hypertension is one where the cause is known. According to WHO guidelines between 2006 and 2015, deaths due to cardiovascular diseases are expected to increase by 17% while the deaths from infectious diseases, nutritional deficiencies, maternal and prenatal conditions are projected to decline by 3%. The main causes of hypertension includes the age ,hereditary, gender, extra weight, alcohol consumption, stress life, lazy life etc.
Hypertension is sometimes referred to as the silent killer (Aycock, Kirkendoll, & Gordon, 2013). Today it is a public health problem. According to the American Heart Association 2013 Statistical Fact Sheet (2013), one out of every three adults has high blood pressure, which is estimated at 77.9 million people (AHA, 2013). High blood pressure is also referred to as hypertension. Hypertension is a prevalent medical condition that carries with it the risk factor for increased chances of heart disease and stroke (Gillespie & Hurvitz, 2013). Hypertension remains one of the top 10 causes of worldwide disability-adjusted life years (as cited in Drenjančević-Perić et al., 2011). For the estimated 348, 102 deaths in 2009, high blood pressure was listed as the primary or contributing cause of death (AHA, 2013). Despite the health risk associated with hypertension, the diagnoses of high blood pressure continue to rise. By 2030, hypertension is expected to increase by 7.2% from 2013 estimates (AHA, 2013).
The two major types of hypertension are primary and secondary. Primary hypertension accounts for more than 90% of all cases and has no known cause, although it is hypothesized that genetic factors, hormonal changes, and the altercations in sympathetic tone all may play a role in its development. Secondary hypertension develops as a consequence of an underlying disease or condition. The prevention and treatment of hypertension is a major public health issue. When blood pressure is controlled, cardiovascular, renal disease, and stroke may be prevented. The JCN, reported more than 122 million individuals in American are overweight or obese, consume large amounts of dietary sodium and alcohol, and do not eat adequate amounts of fruits and vegetables; less than 20% exercise regularly. Both modifiable and non-modifiable factors play a role in the development of hypertension
In order to determine which stage of the Demographic Transition a country is in, you must know what the demographic transition is, what each stage is and how to know if a country is in that stage. The Demographic Transition is a process of change in a society’s population. Stage 1 of the demographic transition is low population growth. If a country is in stage one of the demographic transition that country would have a high Crude Birth Rate(CBR) and a high Crude Death Rate(CDR) that together would produce a low natural increase. Stage 2 of the demographic transition is high growth. If a country is in stage two of the demographic transition, the country would have a declining CDR and a very high CBR that together would produce a high natural
