HTN Types

There are two main types of hypertension:

  • Primary hypertension:
    • The underlying cause for the elevated blood pressure is unknown.
    • Over 95% of people with hypertension have this form.
    • Primary hypertension is also called essential hypertension.
  • Secondary hypertension:
    • The high blood pressure is caused by an underlying illness.
    • Control of the underlying illness may correct the high blood pressure problem
