Primary hypertension is the most common condition, found in 95 per cent of the cases. It has no definite cause. There are several factors that may act in combination, causing the blood pressure to increase.
Secondary hypertension is found in five to ten per cent the cases. Here, the increase in blood pressure is caused by a specific defect in one of the organs in the body. Treating the affected organ can control or cure the hypertension.
Malignant hypertension is severe and can lead to damage of organs such as the heart, kidneys and the brain. Isolated systolic hypertension results from age related loss of elasticity of arteries, when the blood pressure is consistently above 160/91 mm Hg.
White coat hypertension is caused by anxiety and can be controlled by incorporating changes in lifestyle.
Resistant hypertension is a condition in which the blood pressure cannot be reduced below 140/90 mm Hg, despite medication.
Diagnosing, treating and controlling hypertension at an early stage can significantly reduce the risk of developing heart attacks, kidney failure or strokes.
