Yes, there are two types of hypertension: Primary hypertension and secondary hypertension. Primary hypertension, the most common type, is also called essential hypertension. There is no known cause. About 5 percent to 10 percent of people with high blood pressure have it as a result of another condition or problem, such as such as kidney disease, or the use of certain medications, such as birth control pills. This is secondary hypertension.
