Question: Hypertension is divided into two major forms-primary and secondary. In most hypertension cases (95%) in adults, there is no identifiable cause. This type of hypertension, called primary hypertension or essential hypertension, tends to develop gradually over many years. The other cases of hypertension (5%) are caused by an underlying condition. This type of hypertension, called secondary hypertension, tends to appear suddenly or manifests as stable blood pressure that becomes labile. In secondary hypertension, blood pressure levels are higher than in primary hypertension. Secondary hypertension tends to be resistant to antihypertensive agents in recommended doses and with multiple agents. Those patients with secondary hypertension tend to be younger (e.g., < 30), may not be obese, or have a family history. Need Assignment Help?
