Blood pressure is the pressure exerted against the walls of the arteries and veins as the heart pumps blood.
Blood pressure is normal to every human; be it child, youth or adult. However, something goes wrong when the pressure at which blood is being pumped becomes too high. In such situations, a person is said to have high blood pressure.
That said, high blood pressure is when the force of blood pushing against the walls of the arteries becomes too high. High blood pressure is synonymous to hypertension.
Blood pressure readings are written as systolic blood pressure / diastolic blood pressure: for instance, 120/80 mmHg.
Systolic blood pressure – is the blood pressure when the heart contracts, or pumps blood.
Diastolic blood pressure – is the blood pressure between heartbeats, i.e. when the heart relaxes or rests.
Stages of High Blood Pressure.
Normal blood pressure for adults should not exceed 120/80 mmHg, it should be between 90/60 to 120/80. Anything above this is considered abnormal.
There are three categories :
1. Prehypertension : Blood pressure readings between 120/80 and 139/89 fall in this category.
2. Stage 1 high blood pressure : Blood pressure readings between 140/90 and 159/99 are categorized here.
3. Stage 2 high blood pressure : Blood pressure readings between 160/100 or higher fall in this category.
People can have high blood pressure for a long time without them knowing. However, symptoms may begin to show if the blood pressure increases. Some of the symptoms are; headache, feelings of dizziness, nausea, etc.
