High Blood Pressure: Causes,symptoms,treatment
Author: Alexis-Blaise Kenne  | Posted: 13-03-2008 | Comments: 0 | Views: 20 | Rating: (55)  (?) 
Blood pressure is the force of the blood pushing against the walls of the arteries. Blood pressure is the result of two forces: from the heart as it pumps blood into the arteries and throughout the circulatory system, and the force of the arteries as they resist blood flow. Blood pressure is measured by putting a blood pressure cuff around your arm, inflating the cuff and listening for the flow of blood. Blood pressure is always given as these two numbers, the systolic and diastolic pressures. Blood pressure is traditionally measured with a device called a sphygmomanometer. Blood pressure is measured in millimeters of mercury (mm Hg). Blood pressure is generally felt to be abnormally high at a level of 140/90, and some sort of definitive therapy and follow-up should be started at this level. High blood pressure is called the silent killer because it usually has no symptoms.
Blood is carried from the heart to all parts of your body in vessels called arteries. Blood does not flow regularly like water from a tap:-When the heart contracts (systole), the blood is propelled into the main arteries that act as a pressurised reservoir.
Pressure in a hose can be regulated either by controlling the rate at which fluid passes through it or by widening it. Pressure inside your arteries can cause the muscles that line the walls of the arteries to thicken. Your blood pressure is at its highest when the heart beats, pumping the blood. When the heart is at rest, between beats, your blood pressure falls. Still, for most of your waking hours, your blood pressure stays pretty much the same when you are sitting or standing still.
Heart disease is the UK’s biggest killer, claiming thousands of lives each year. Heart failure is when your heart cannot pump blood around the body as well as it should, and this can cause you to become short of breath and can cause your ankles to swell. Heart attack High blood pressure is a major risk factor for heart attacks.
Various disorders and drugs can cause the compensatory mechanisms to malfunction, and high blood pressure may result. Causes In most instances of high blood pressure, no known cause can be identified. Doctors do not know what causes high blood pressure in 90 to 95 percent of people who have it. For some people, just being in a medical setting causes their blood pressure to rise.
Symptoms When blood pressure is too low, the first organ to malfunction is usually the brain. Symptoms that may occur include: Confusion Chest pain Ear noise or buzzing Irregular heartbeat Nosebleed Tiredness Vision changes. What is treatment, medication, medicines, remedy, drugs, cure of lowering high Blood pressure or Hypertension? . Although high blood pressure, also known as hypertension, can cause headaches, dizziness and problems with vision, the majority of people with the condition do not display any noticeable symptoms.
Treatment
Treatment is focused on reducing water retention and lowering blood pressure to normal limits. Treatment for high blood pressure depends on the severity of the disease and whether you have other health problems, such as heart failure or diabetes, or you are pregnant. Treatment of primary high blood pressure, especially moderate or severe high blood pressure, decreases the risk of heart failure, coronary artery disease, heart attack, abnormal heartbeats, stroke, and kidney disease, and reduces the risk of death from these conditions. Treatment for high blood pressure must be highly individualized and based on your risk factors, such as diabetes, smoking, and heart disease. Treatment when blood pressure increases slightly and the woman is not near the end of her pregnancy, bed rest may help reduce the pressure. Treatment begins with changes you can make in your lifestyle to help lower your blood pressure and reduce your risk of heart disease .
High blood pressure is called the silent killer because it usually has no symptoms. When high blood pressure is not found and treated, it can cause: The heart to get larger, which may lead to heart failure. If your blood pressure is in the prehypertension range, it is more likely that you will end up with high blood pressure unless you take action to prevent it. High blood pressure is dangerous because it makes the heart work too hard and contributes to atherosclerosis (hardening of the arteries). If your blood pressure is between 120/80 mmHg and 139/89 mmHg, then you have prehypertension. The good news is that if your blood pressure is high, it can be lowered by making changes to your lifestyle, for example changing your diet, exercising and losing weight, and when needed, with tablets. The medical community?s knowledge of high blood pressure is great, but far from perfect. High blood pressure is more common: In patients whose families have high blood pressure In those over 35 years old In males In Afro-Americans In women on oral contraceptives. The only way to know whether you have high blood pressure is to have it taken by a person who knows how (those automatic machines you sit at in the supermarket are not necessarily kept accurate condition.

Lice
By: nagalie | 22-07-2008
I am so grossed out, tired, and aggrivated. I need help. I need some feedback. To begin with, I'm an ultra clean person but I think I have lice. I am not sure. for a week now I have been itching like crazy but didn't find anything until today. I can never find anything at will. Nothing in the seems of my clothes. I only feel them. anyway, today I found on my arm ( think it fell from my head) what I now know looks like lice according to pictures i've seen. It had 6 legs was a transparent brown exept for the dark insides of its body. It was about the size of the period at the end of this sentence but a bit larger including it's legs...(Sooo sorry that you are getting this gross info but it's quite necessary for the process of identifying my problem.) Anyway, I am pretty sure it is lice but the question i want to ask now is what kind? If it is body lice it should be treated different from head lice I think. I know you can get rid of head lice with olive oil but body lice? Here are my symptoms... I am 90% sure I got this from my dog who was in some tall grass the other day. I saw her itching intensely but shes never had any bites before so I didnt think about it. I thought it was allergies and gave her a benedryl. THEN I started itching along with her. I know its not fleas. I don't think its scabies because my bites dont run in lines or around the webbing of my fingers. Not only that but scabies dont look like lice from what I know. Now, I can't tell if it is head or body lice because of this, they are both on my head and on my body. I even feel them in my eyelashes. I have them in my nether regions...and I've never had sex.lol I have bites that look like pimples all spread out on my legs...nether region...round my belly button, on my behind, back and neck. None on my chest or face thank God for that. But head lice are supposed to remain on the head for all I know and body lice on the body. I even feel itchy in my ears. I can barely sleep. Someone help me so I can search for a remedy pleeease. If you have a remedy for either please share it with me . Thanks
