|Blood pressure is the pressure of the blood as it is circulated in the arteries. Each time the heart beats it squirts a relatively small volume of blood into the arterial system momentarily boosting the pressure of the circulating blood.|
Think of blood pressure as you would the mains pressure in the household water pipes.
Systolic blood pressure is the higher level of pressure which occurs each time the heart beats. Diastolic blood pressure is the lower level existing when the heart relaxes in between beats, and is the resting level of pressure.
Hypertension is a blood pressure higher than normal.
Hypotension is blood pressure lower than normality.
Normal levels of blood pressure are hard to define. If your doctor is concerned, it may be necessary to take several readings spread over several weeks to months before a decision is made to put you on to medication. This is also because you might have to take it for the rest of your life.
Symptoms of raised blood pressure are few until the pressure is dangerously high. So each time you have a check-up with your local doctor, your blood pressure should be measured.
Increased blood pressure gradually throws a strain on the blood vessels causing them to lose their elasticity and harden. This causes narrowing of the arteries which produces a further increase in blood pressure. A high fat diet which clogs up and narrows blood vessels can complicate the picture. With high blood pressure, the heart feels a stain when it attempts to pump blood through the body, resulting in a general onset of heart disease.
The types of high blood pressure are :
Blood pressure readings can be influenced by anxiety, by the time of day - it is generally lower early in the morning and higher towards the end of the day, but the lowest reading is during sleep. It can be affected by the stress which you experience during the day.
