Hypertension or High Blood Pressure
Causes of Hypertension There is no specific cause of hypertension among 90-95% of patients having high blood pressure. Hypertension without a known cause is called "Primary Hypertension" or "Essential Hypertension." The cause of Essential Hypertension could be genetic or environmental factors. The factors of high blood pressure are not same for all patients. The remaining 5-10% of patient with high blood pressure have a known cause and they are considered to have "Secondary Hypertension". Causes of Secondary Hypertension could be kidney failure, narrowing of the arteries to the kidneys, and various hormonal conditions.
Some risk factors for getting hypertension can be changed, while others cannot. Age, gender, and race are risk factors that a person obviously can do very little about.
