Step-by-step explanation:
Primary hypertension, also known as essential hypertension, is a chronic medical condition characterized by chronically elevated blood pressure in the arteries. It is caused by a combination of genetic and lifestyle factors. Primary hypertension accounts for approximately 90% of all cases of high blood pressure. Lifestyle factors such as excess dietary salt and alcohol consumption contribute to the risk of developing primary hypertension. On the other hand, secondary hypertension, which makes up the remaining 10% of cases, is caused by underlying medical conditions such as chronic kidney disease or an endocrine disorder. It is important to control hypertension through medications or lifestyle changes to reduce the risk of cardiovascular diseases.
