The heart is a pump that is designed to force blood through the body and as with any type of pump, it works by generating pressure. In the body, the blood is pumped through the arteries to all major organs, but if there is too much pressure it can put a strain on the heart itself or the arteries, causing all sorts of problems.

Blood pressure is dependent on two things. The first is the force with which the heart pumps the blood around the body, and the second is the narrowness of the arteries. Hypertension happens when the blood is forced with increased pressure through the arteries.

When blood pressure is measured, it is done so using two numbers, an example being 120 over eighty. The first number listed is the systolic blood pressure which is the maximum pressure exerted on the arteries when the heart beats, and the second number listed is the diastolic blood pressure, or the minimum amount of pressure on the arteries when the heart is relaxed. The example above is of a normal blood pressure reading.

Blood pressure can be considered high when the systolic blood pressure reading is constantly above 160, and/or the diastolic blood pressure reading is above 100. One of the biggest problems with high blood pressure though, is the fact that it doesn’t always cause any symptoms meaning it may go unnoticed until a later complication such as a heart attack or stroke.

Other complications arising from high blood pressure can be an aneurysm, heart failure, eye damage, kidney failure or atherosclerosis, which is the narrowing of the arteries. Some factors that could contribute to high blood pressure include hereditary reasons, obesity, kidney disease, diabetes, excessive salt intake, lack of exercise and high intake of alcohol.
