Usually hypertension is defined as blood pressure above 140/90, and is considered severe if the pressure is above 180/120. High blood pressure often has no symptoms. Over time, if untreated, it can cause health conditions, such as heart disease and stroke. It is defined as transitory (short-lived) or chronic elevation of the blood pressure in the arteries. This elevation may lead to cardiovascular damage. Although the heart and blood vessels can tolerate increased blood pressure for months and even years, eventually the heart may enlarge (a condition called hypertrophy) and be weakened to the point of failure. Injury to blood vessels in the kidneys, brain, and eyes also may occur. High blood pressure affects around 1 in 3 Australian adults.
