Our heart is a pumping system that pumps blood to all the organs of our body with our circulatory system. Heart separates deoxygenated blood from the oxygenated blood. It pumps oxygenated blood to our cells and takes in deoxygenated blood. It then makes sends the deoxygenated blood to our lungs to make it oxygenated again.
Our cells get oxygen and nutrition from the blood and excrete carbon dioxide and waste to the blood. So, since the blood has a long way to travel, the heart has to send it with pressure so that it can easily flow against the side of arteries and reach each of our cells. So, this pressure with which the blood flows through our arteries is called blood pressure (BP).
There are two types of pressure numbers noted down while measuring the blood pressure – the systolic pressure and diastolic pressure. Systolic pressure is the blood pressure when the heart beats while pumping the blood and diastolic blood pressure is the blood pressure when heart is resting between the beats. The ideal blood pressure is 120mmHg (systolic) / 80mmHg (diastolic)
What is High Blood Pressure (Hypertension)?
A person is said to have high blood pressure or hypertension or high BP if his/her blood pressure is always 140 over 90. Meaning systolic pressure is over 140 and diastolic pressure is over 90.
Anyone can have high blood pressure. Even a person who looks very healthy can have high blood pressure. When your blood is high in pressure it can stretch, scar and damage your arteries. It may lead to heart attack, kidney disease or heart failure.
Understanding High Blood Pressure
Reasons for High Blood Pressure
There are a lot of factors that could lead to high blood pressure. There are no exact causes of high blood pressure known till now. Here are the most potential factors :
Overweight, high amount of salt intake in diet, stress and tension, smoking, drugs, family history, lots of drinking, old age, less physical activities, kidney diseases, etc.
Symptoms of High Blood Pressure
Just like I told earlier, even a very normal looking person can have high blood pressure in fact the children could have it (though chances are very low). So, how do you tell if a person is looking healthy or is actually healthy? If the person has high blood pressure or not? Most of the person suffering from high blood pressure might not show any symptoms untill the blood pressure is dangerously high like 180/110 mmHg.
There are a few symptoms counted for high blood pressure :
- Headache lasting for several days
- Blurred vision
- shortness of breath
- Nausea, discomfort in stomach
- Respiratory problems
If anyone experiences these symptoms then he/she should visit the doctor.
Children can show the following symptoms of high blood pressure : blurred vision, headache, nose bleed, inability to control facial muscles on any side of face.
