What Is the Difference between High
and Low Blood Pressure?

High blood pressure (hypertension) that goes undetected or isn’t properly controlled can lead to heart attack, heart failure, kidney failure, stroke or premature death. It is caused by a clogging of blood vessels due to a plaque build-up of cholesterol and fat. Unfortunately there are few symptoms, so many don’t even know they have a raised blood pressure, which could be life-threatening.

Low blood pressure (hypotension) occurs when the pressure of the blood flow is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys. Symptoms include lightheadedness, dizziness or fainting, especially when standing up after sitting.
