If your blood pressure readings are rising by the day, you need a prescribed treatment plan. Read further to understand the causes, diagnosis, management and symptoms of high blood pressure.

Blood pressure is the pressure exerted against the walls of the arteries when the heart pumps blood for the body. Causes of high blood pressure could be a number of reasons like age, genetics, obesity, sedentary lifestyle and race. Other than the medications, there are a few things you can do to manage and control it. 

What is high blood pressure?

High blood pressure or hypertension is when the force of blood inside the arteries is at an all time high. The normal blood pressure is about 120/80 mmHg where 120 is the systolic value and 80 is the diastolic value. Systolic blood pressure is the pressure in the arteries when the heart beats while diastolic blood pressure is the pressure in the arteries when the heart is at rest between beats.

Elevated blood pressure - Systolic - 120-129 mmHg ; Diastolic - less than 80 mmHg 

Hypertension stage 1 - Systolic - 130 - 139 mmHg ; Diastolic - 80-89 mmHg 

Hypertension stage 2 - Systolic - 140 mmHg or higher ; Diastolic - 90 mmHg or higher

Hypertensive crisis - Systolic - Higher than 180 mmHg ; Diastolic - Higher than 120 mmHg 

Elevated blood pressure can be managed in most cases with lifestyle changes while all the other stages beyond might require a medical treatment.
