High blood pressure or hypertension is one of the most often health problems throughout the world.

High blood pressure plays a crucial role in cases of heart attack statistics show. Almost every family has member with high blood pressure. Alarming is also the fact that over the past 15 years have seen a lowering of the age limit for the occurrence of hypertension.

What do you know about high blood pressure?

Blood pressure corresponds to the pressure / pressure /, which are on the walls of the arteries in which blood passes. This blood pressure is expressed by two numbers eg 15/9 or 150/90, which correspond to the pressure expressed in inches or millimeters. The higher value – 15 or 150 is the systolic blood pressure, it corresponds to the maximum pressure when the heart is contracting. The lower – 9 or 90, diastolic blood pressure, it corresponds to the minimum pressure in the arteries when the heart is resting between two cuts.

The values of normal blood pressure are not the same for all ages. In children, the values are lower in middle-aged people – higher for adults – even higher. For people between 16 – and 30-year-old normal systolic pressure is between 115 and 160 mm, and diastolic – between 60 and 85 mm Hg. For persons over the age of 50 normal systolic blood pressure can move between 115 and 160 mm and diastolic – between 70 and 95 mm. Any diastolic pressure above 95 mm should be considered abnormal regardless of age.

The values for blood pressure should not be considered absolute and decisive, since blood pressure may show some abnormalities. For example, in the same person the blood pressure can vary day to day or hour to hour throughout the day. They decreased during sleep back, increase during effort in emotion, stress, pain and more.

Of importance is the difference in blood pressure in the past and present.

When blood pressure measured three times at a complete standstill for people in middle age, show values above 150 mm systolic and 90 mm for diastolic pressure, it is assumed that there is increased blood pressure / hypertension /. When the systolic pressure to 170-180 mm, it is assumed that hypertension is moderate, as 200-220 above that hypertension is high grade.
