Symptoms of Hypertension : Uncomplicated high blood pressure usually occurs without any symptoms. Therefore, hypertension has been labeled "the silent killer." In other words, the disease can progress without symptoms (silently) to finally develop any one or more of the several potentially fatal complications of hypertension. As a matter of fact, uncomplicated hypertension may be present and remain unnoticed for many years, or even decades. This happens when there are no symptoms and those affected fail to undergo periodic blood pressure screening. Some people with uncomplicated hypertension, however, may experience symptoms such as headache, dizziness, shortness of breath, and blurred vision. The presence of symptoms can be positive in that they can prompt people to consult a doctor for treatment and make them more compliant in taking their medications. Not infrequently, however, a person's first contact with a physician may be after significant damage to the organs has occurred. In many cases, a person visits or is brought to the doctor or an emergency room with a heart attack, stroke, kidney failure, or impaired vision (due to damage to the back part of the retina). Greater public awareness and frequent blood pressure screening may help to identify patients with undiagnosed high blood pressure before significant complications have developed. About one out of every 100 (1%) people with hypertension is diagnosed with severe high blood pressure (accelerated or malignant hypertension) at their first visit to the doctor. In these patients, the diastolic blood pressure (the minimum pressure) exceeds 140 mm Hg! Affected persons often experience severe headache, nausea, visual symptoms, dizziness, and sometimes kidney failure. Malignant hypertension is a medical emergency and requires urgent treatment to prevent a stroke
Stress is simply a fact of nature -- forces from the outside world affecting the individual. Hence, all living creatures are in a constant interchange with their surroundings (the ecosystem), both physically and behaviorally. This interplay of forces, or energy, is of course present in the relationships between all matter in the universe, whether they are living (animate) or not living (inanimate). However, there are critical differences in how different living creatures relate to their environment. These differences have far reaching consequences for survival. Because of the overabundance of stress in our modern lives, we usually think of stress as a negative experience. But from a biological point of view, stress can be neutral, negative, or positive. Stress has driven evolutionary change (the development and natural selection of species over time). Thus, the species that adapted best to the causes of stress (stressors) have survived and evolved into the plant and animal kingdoms we now observe. Man, because of the evolution of the human brain, especially the part called the neo-cortex, is the most adaptive creature on the planet. This adaptability is largely due to the changes and stressors that we have faced and mastered. Therefore, we, unlike other animals, can live in any climate or ecosystem, at various altitudes, and avoid the danger of predators. Moreover, most recently, we have learned to live in the air, under the sea, and even in space, where no living creatures that we know of have ever survived. There is now speculation, as well as some evidence, that points to the abnormal stress responses as being involved in causing various diseases or conditions. These include anxiety disorders, depression, high blood pressure, certain ulcers and other gastrointestinal diseases, some cancer, and even aging itself. Stress also seems to increase the frequency and severity of migraine headaches, asthma attacks, and blood sugar fluctuations in diabetics. Overwhelming psychological stress (such as the events of Sept. 11th) can cause both temporary (transient) and long lasting (chronic) symptoms of a serious psychiatric illness called posttraumatic stress disorder.
Causes of Panic Disorder : According to one theory of panic disorder, the body's normal "alarm system," the set of mental and physical mechanisms that allows a person to respond to a threat, tends to be triggered unnecessarily, when there is no danger. Scientists don't know exactly why this happens, or why some people are more susceptible to the problem than others. Panic disorder has been found to run in families, and this may mean that inheritance (genes) plays a strong role in determining who will get it. However, many people who have no family history of the disorder develop it. Often, the first attacks are triggered by physical illnesses, a major life stress, or perhaps medications that increase activity in the part of the brain involved in fear reactions.
Medical Treatment Of Hypertension : Keep in mind that high blood pressure is usually present for many years before its complications develop. The idea, therefore, is to treat hypertension early, before it damages critical organs in the body. Accordingly, increased public awareness and screening programs to detect early, uncomplicated hypertension are the keys to successful treatment. The point is that by treating high blood pressure successfully early enough, you can significantly decrease the risk of stroke, heart attack, and kidney failure. The goal for patients with combined systolic and diastolic hypertension is to attain a blood pressure of 140/85 mm Hg. Bringing the blood pressure down even lower, as mentioned earlier, may be desirable in black patients and patients with diabetes or chronic kidney failure. Blood pressure that is persistently higher than 140/ 90 mm Hg usually is treated with lifestyle modifications and medication. If the diastolic pressure remains at a borderline level (usually under 90 mm Hg, yet persistently above 85), however, treatment also may be started in certain circumstances. These circumstances include borderline diastolic pressures in association with end-organ damage, systolic hypertension, or factors that increase the risk of cardiovascular disease, such as age over 65 years, black race, smoking, hyperlipemia (elevated blood fats), or diabetes.
