If the blood pressure falls between the range of 120/80 mmHg and 140/90 mmHg it is termed as ‘pre-hypertension’.
High blood pressure can be dangerous as it makes the heart work harder. Hypertension is a ‘silent killer disease’ and it often has no signs and symptoms. If left untreated it can increase the risk of heart disease, stroke as well as kidney failure and eye damage. Some people may not realize they have high blood pressure until they have problems with their blood, heart or kidneys.
Almost one in every three people suffers from this condition and this may be related to our modern lifestyle and dietary changes. Consumption of salt, smoking, obesity, lack of exercise and stress are some of the factors that can lead to increase in the blood pressure.
Classification of hypertension
- Primary (essential) hypertension - High blood pressure with no obvious underlying medical cause.
- Secondary hypertension - High blood pressure caused by other conditions that affect the kidneys, arteries, heart or endocrine system.
- Headaches, dizziness or nosebleeds are the common warning signs of high blood pressure.
Adopting healthy lifestyle habits is an effective first step in both preventing and controlling high blood pressure. Diuretics, beta-blockers, ACE inhibitors and calcium channel blockers can be used for treating hypertension.
High blood pressure is a chronic condition and usually lasts a lifetime once it is developed.
What are the Causes of High Blood
The causes of high blood pressure may vary according to individuals.
In 90 - 95% cases of high blood pressure, there is no specific underlying medical condition. Many patients have high blood pressure for years and do not know it. When the cause is unknown it is called essential hypertension or primary hypertension.
Certain associations have been noticed with people having essential hypertension. They include
- A high intake of salt
- Hereditary (genetic) susceptibility (30%)
- Kidney failure (renal insufficiency)
- Lack of exercise
- Aging inflammation
- Narrowing of certain arteries
- Kidney abnormality
- Structural abnormality of the aorta existing from birth
- Adrenal gland diseases
- Thyroid diseases
- Pre-eclampsia, a significant increase in blood pressure during the last 3 months of pregnancy.
- Use of illegal drugs such as cocaine and amphetamines.
- Medications like birth control pills, cold remedies, decongestants, pain relievers.
- Metabolic Syndrome is also a cause of developing hypertension.
- Age - Blood pressure increases as age increases.
- Race - High blood pressure is more common in blacks than in whites.
- Sex - In young adulthood and early middle age, men have high blood pressure more often than women.
- Genetics - High blood pressure tends to run in families
