Blood pressure is the force of your blood pushing against the walls of your arteries . Blood pressure is measured in millimetres of mercury (mmHg). Your blood pressure is recorded as two figures. For example, 120/80 mmHg.
SYMPTOMS OF HYPERTENSION
Hypertension is a ‘silent killer’. There maybe no symptoms or mild symptoms like headache, swelling over face and feet, fatigue etc. It can lead to heart attacks, stroke, kidney failure. You will not know if you have high blood pressure unless you have your blood pressure checked.
Risk factors for heart problems
Everybody has some risk of developing heart disease. However, certain ‘risk factors’ increase the risk. These include:
LIFE STYLE RISK FACTORS THAT CAN BE PREVENTED OR CHANGED
- Sedentary lifestyle
- An unhealthy diet
- Excess alcohol
TREATABLE OR PARTLY TREATABLE RISK FACTORS
- Hypertension (high blood pressure)
- High cholesterol/triglyceride blood level
- Kidney diseases
FIXED RISK FACTORS – ONES THAT YOU CAN NOT ALTER:
- A strong family history. This means if you have a father or brother who developed heart disease or a stroke before they were 55, or in a mother or sister before they were 65

What is high blood pressure?
- 120/80 or lower is normal BP
- 140/90 or higher is high BP
- 120-139 systolic and 80-89 diastolic is pre-hypertension
Depending on various factors, the level at which blood pressure is considered high enough to be treated with medication can vary from person to person.
Blood pressure between 130/80 and 140/90 mm is too high for certain groups of people. Treatment to lower your blood pressure if it is 130/80 mmHg or higher may be considered if you:
- Have a complication of diabetes, especially kidney problems.
- Have had a event such as a heart attack, transient ischaemic attack (TIA) or stroke, kidney disease.
How is high blood pressure diagnosed?
BP maybe high due to anxiety, stress, exercise, post meal or caffeine intake. A single BP reading that is high does not mean that you have hypertension. Several blood pressure readings that are high on different occasions checked in a relaxed environment indicate hypertension.
If one reading is found to be high, it is usual for your doctor or nurse to advise a time of observation. This means several blood pressure checks at intervals over time.
What is "white-coat hypertension"?
Some people have high BP on getting it checked in the medical clinic or hospital but are otherwise normotensive. To prove this, you may be advised ‘ambulatory blood pressure monitoring by a device which easily measures your blood pressure continuously over 24 hours.
What causes high blood pressure?
If there is no underlying cause identified for high BP, it is called ‘essential hypertension’. If there is any disease like a hormone imbalance or kidney disease, it is called ‘secondary hypertension’. Most people have essential hypertension. People who develop high BP at a young age should be investigated for secondary causes.
