Blood pressure is the force of blood against the walls of your arteries. Blood pressure is necessary to move the blood through your body so it can get to all the body's organs.

Why is high blood pressure dangerous?

High blood pressure—also called hypertension—puts you at risk for heart disease. When your

circulatory system

blood pressure is high, your heart has to work harder. High blood pressure is known as the "silent killer" because it often has no symptoms. If not treated, high blood pressure raises your chances of:


Heart attack

Kidney problems

Eye problems


The good news

You can take action to prevent high blood pressure. If your blood pressure is high, you can do something to control it.

What do your blood pressure numbers mean?

A normal blood pressure is below 120/80. Check your blood pressure once a year.

If your numbers are 120/80 to 139/89, you have prehypertension. You are more likely to end up with high blood pressure. Take action to prevent it.

Your blood pressure is high if it is 140/90 or above. Ask your doctor how to lower it. Check your blood pressure often if your blood pressure is high.

Thank you,but how and why blood pressure rises.


Many reasons, main ones i would say are stress, illness, and being overweight. Other short term risers would be alcohol or exercise.


Yes and also it rises a bit with age, but many say it should not. A diet containing lots of hydrogenated (trans) fats also puts bp up. Can go high in pregnancy.  Many people blame the stress of modern day living, too. 


You are right. But the main factor for rise in blood pressure is fatty deposits in blood vessels called atherosclerosis.


I have had labile BP for 16 years that meds and the hypertension Clinic have not controlled. I've had every test in the book and two angiograms that show my arteries to be clear after false positives during stress ECG's and Echocardiograms.


Labile or idiopathic blood pressure do occur in about 10% of hypertensives. Here cause is unknown, so management is difficult and treatments is very unsatisfactory. Sorry for that.


Consultant suggested that I am not truly hypertensive but have spikes. My average from 24 hour monitoring keeps them happier than me.

He suggested that not being truly hypertensive is the reason that all drugs tried gave me side effects and did not reduce the mainly morning highs.


You knew all along then! 😉
