Blood pressure is defined as the force that the blood applies on the arteries as it flows. Optimal blood pressure with respect to cardiovascular risk is less than 120/80 mm Hg (source: americanheart.org).
A person with a high blood pressure means that he or she has “Hypertension”. This is regarded as a silent killer and has no definite symptoms to watch out for. The best way to determine if you have a high blood pressure is to have your blood pressure checked on a regular basis.
If you have hypertension, consult your doctor right away for proper treatment. You would likely be advised to control your blood pressure by exercising more, lowering your salt intake, drinking alcohol in moderation, reduce stress, and avoiding foods that can trigger hypertension.
