What is high blood pressure?
A blood pressure of 140/90 or higher is considered high blood pressure. Both numbers are important. If one or both numbers are usually high, you have high blood pressure. If you are being treated for high blood pressure, you still have high blood pressure even if you have repeated readings in the normal range.

What Is Systolic and Diastolic Blood Pressure?
The blood pressure reading is measured in millimeters of mercury (mm Hg) and is written as systolic pressure, the force of the blood against the artery walls as your heart beats, over diastolic pressure, the blood pressure between heartbeats. For example, a blood pressure reading is written as 120/80 mm Hg, or "120 over 80". The systolic pressure is 120 and the diastolic pressure is 80.
4. What Health Problems Are Associated With Hypertension?
Several potentially serious health conditions are linked to hypertension, including:
v
* Atherosclerosis: a disease of the arteries caused by a buildup of plaque, or fatty material, on the inside walls of the blood vessels. Hypertension contributes to this buildup by putting added stress and force on the artery walls.
* Heart Disease: heart failure (the heart can't adequately pump blood), ischemic heart disease (the heart tissue doesn't get enough blood), and hypertensive hypertrophic cardiomyopathy (enlarged heart) are all associated with high blood pressure.
* Kidney Disease: Hypertension can damage the blood vessels and filters in the kidneys, so that the kidneys cannot excrete waste properly.
* Stroke: Hypertension can lead to stroke, either by contributing to the process of atherosclerosis (which can lead to blockages and/or clots), or by weakening the blood vessel wall and causing it to rupture.
* Eye Disease: Hypertension can damage the very small blood vessels in the retina.

Normal Blood Pressure - Blood pressure reading below 120/80 is considered normal.
High Blood Pressure - Blood pressure of 140/90 or higher is considered high blood pressure. If one or both numbers are usually high, you have high blood pressure.
Low Blood Pressure - Blood pressure that is too low is known as hypotension. The similarity in pronunciation with hypertension can cause confusion.

Systolic pressure (mm Hg) | Diastolic pressure (mm Hg) | Stages of High Blood Pressure |
210 | 120 | Stage 4 |
180 | 110 | Stage 3 |
160 | 100 | Stage 2 |
140 | 90 | Stage 1 |
Systolic pressure(mm Hg) | Diastolic pressure (mm Hg) | Pressure Range |

The Signs and Symptoms of High Blood Pressure
Signs of high blood pressure include, headache dizziness, pounding in ears, and a bloody nose. These symptoms typically don't occur until high blood pressure has reached an advanced and even a possibly life threatening stage. see other Signs of High Blood Pressure
What causes high blood pressure?
For most people who suffer with hypertension, there is no obvious cause why their blood pressure is high. This condition is called essential hypertension and it is especially important that it is kept under control. More information on What causes High Blood Pressure?
Measuring your blood pressure.
Healthcare professionals use a stethoscope and a manual sphygmomanometer to measure your blood pressure. Typically they take the reading above your elbow. The sphygmomanometer has a bladder, cuff, bulb, and a gauge. When the bulb is pumped it inflates the bladder inside the cuff, which is wrapped around your arm. This inflation will stop the blood flow in your arteries. The stethoscope is used to listen for sound of the heartbeat, and no sound indicates that there is no flow. As the pressure is released from the bladder, you will hear the sound of the blood flowing again. That point becomes systolic reading. The diastolic reading is when you hear no sound again, which means that the blood flow is back to normal.
Blood pressure 100 plus your age
Medical research shows that as we age blood pressure rises slightly to accommodate an increased demand of oxygen and nutrients. It is completely natural for the first number (systolic) to be 100 plus our age. A recent study by a group of UCLA researchers came very close to corroborating Dr. Piette's guide for blood pressure of 100 plus your age for men, subtracting 10 for women, and this is after this rule had been in use for five or more decades. Are we now being taught that Dr. Piette's guide for blood pressure is wrong merely for drug company profit?
Symptoms of heart attack
The heart requires blood to bring oxygen, and nutrients to its muscle tissue. The narrowing of the arteries due to blockage can cause high blood pressure. If this blockage occurs in the arteries of the heart, coronary arteries, heart muscle damage can occur, resulting in a heart attack
Some heart attacks are sudden and intense, however most heart attacks start slowly with mild pain and discomfort. Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness or pain. Shortness of breath may occur, as well as nausea, or lightheadedness. It is vital to get help immediately if any of these symptoms occur.
Symptoms of a stroke
The brain requires unobstructed blood flow to nourish its many functions. Very high, sustained blood pressure will eventually cause blood vessels to weaken. Over time these weaken vessels can break, and blood will leak into the brain. The area of the brain that is being fed by these broken vessels start to die, and this will cause a stroke. Additionally, if a blot clot blocks a narrowed artery, blood ceases to flow and a stroke will occur.
Symptoms of a stroke include sudden numbness or weakness of the face, arm or leg, especially on one side of the body, confusion, trouble speaking, or seeing, sudden severe headache. If you or someone with you has one or more of these signs, don't delay, call 911.
You are at risk for cardiovascular disease if:
a) You smoke - Cigarette smokers are at greater risk than pipe and cigar smokers, but all forms of tobacco are proven to be detrimental to the hearts health.
b) You have diabetes.
c) You are overweight - Persons that have an excess of body fat are at a higher risk than persons of normal weight.
d) Your diet is high in saturated fats.
e) Family History - Children of parents that developed heart disease before the age of 55 have a higher risk of developing heart disease.
f) You exercise less than 30 minutes per day - Inactivity puts a person at higher risk of developing heart disease.
g) You are over 40 or a post-menopausal woman - Risk of heart disease increases over the age of 45 in males, over 55 in females.
h) You consume more than two alcoholic drinks per day.
i) You have high blood pressure or need medication to control your blood pressure.
j) You have high cholesterol levels or need medication to control your cholesterol level.
If you answered yes to one or more of the above, you should talk to your doctor about how you can reduce your risk through lifestyle modifications. Your doctor will determine if preventative therapies such as ASPIRIN 81mg are right for you.
Medications for reducing high blood pressure
There are several types of blood pressure medications and if one doesn't work, then ask your doctor to switch to another until your blood pressure becomes stable.
Adalat - A dihydropyridine calcium blocker. It is mostly used for treating hypertension and Angina Pectoris. Other conditions that benefit from Adalat are Raynaud's phenomenon, Tetanus and Angina Pectoris. Brand names of the drug include Procardia and Nifedical. More information on Adalat
Aldactone - While regularly prescribed for high-blood-pressure patients, the drug can also be prescribed along with other drugs. However, the drug is useful only for controlling, rather than curing, high blood pressure.
