High blood pressure is turning to be one of the world’s biggest killers. It is causing high death rates among people in developing countries like China and India.
According to a research by scientists from the University of Auckland in New Zealand, about 54% of all strokes, 47% of ischaemic heart disease, 75% of hypertensive disease and 25% of other cardiovascular disease globally resulted from high blood pressure. The study has been published in Medical Journal The Lancet in May 2008
The high blood pressure or hypertension may be divided into three types: Mild Hypertension, Moderate Hypertension and Severe Hypertension. The high blood pressure range values are given below.
Systolic Blood Pressure Range mm Hg | Diastolic Blood Pressure Range mm Hg | Condition |
| 140-160 | 90-100 | Mild Hypertension |
| 160-180 | 100-110 | Moderate Hypertension |
| 180-210 | 110-125 | Severe Hypertension |
| Above 210 | Above 125 | Very Severe Hypertension |
If you have high blood pressure, then your heart exerts more force to pump the same quantity of blood within the same time. This puts you at the risk of developing narrowed arteries, which can lead to heart problems, kidney disease, stroke, congestive heart failure and blindness. Note that heart disease and stroke are the first- and third-leading causes of death America.
There are no physical symptoms of high blood pressure; you may not know it for years. Therefore high blood pressure is often called the silent killer. The only way to know is to have it measured. You may have hypertension warning signs such as sweating, headaches, dizziness, quick exhaustion (shortness of breath), a rapid pulse or palpitation and vision disorder (eye symptoms of high blood pressure). Hypertension can cause damage to the blood vessels in the retina, known as hypertensive retinopathy.
If you observe any of these signs, you MUST go to your doctor.
The main causes of having high blood pressure are diet and lifestyle factors.
- Hereditary
- High cholesterol
- Mental tension/stress/worries/fear/work pressure/competitive life
- Lack of exercise/sedentary lifestyle
- Excessive consumption of common salt, sugar and/or fat can cause high blood pressure. Of the estimated one billion people living with high blood pressure or hypertension, about 30% can be due to excess salt intake," says Dr. Ken Flegel and Dr. Peter Magner.
Know about high sodium or salt foods and Daily Salt Intake Recommendation. - Nutritional deficiencies : People whose diets are low in potassium, magnesium, calcium and vitamin C are at greater risk of hypertension.
- Overweight, obesity
- Smoking
- Excessive consumption of alcohol.
The good news is that it is possible to treat high blood pressure by simple lifestyle changes.
