Types of Hypertension

Types list: The list of types of Hypertension mentioned in various sources includes:

  • Primary Hypertension - the main type with no underlying cause
  • Secondary Hypertension - where it is caused by some other underlying condition; much less common than primary hypertension.
  • Hypertension subtypes based on ranges:
    • Optimal Blood Pressure - systolic < 120 mmHg and diastolic < 80 mmHg.
    • Normal Blood Pressure - systolic < 130 mmHg and diastolic < 85 mmHg.
    • High-Normal Blood Pressure - systolic 130-139 mmHg or diastolic 85-89 mmHg.
    • Hypertension Stage 1 - systolic 140-159 mmHg or diastolic < mmHg.
    • Hypertension Stage 2 - systolic 160-179 mmHg or diastolic 90-99 mmHg.
    • Hypertension Stage 3 - systolic >= 180 mmHg or diastolic >= 110 mmHg.
    • Isolated systolic hypertension (ISH) - high systolic pressure only.
  • Hypertension during pregnancy:
    • Gestational hypertension - early stages of high blood pressure during pregnancy.
    • Preeclampsia - severe high blood pressure during pregnancy; about 5% of pregnancies.
    • Eclampsia - very severe pregnancy hypertension leading to seizures.
  • Pulmonary hypertension - hypertension occurring in the heart-lung arteries.
  • Malignant hypertension - occurring in younger adults than the normal profile for essential hypertension

Types discussion: Often in older adults the first number (the upper or systolic number) is high while the second (the lower or diastolic) number is normal. This condition is called isolated systolic hypertension, and it also should be treated. Studies prove that lowering the systolic number cuts down on strokes and heart attacks in people age 60 and over. 1

Some cases of HBP are caused by other illnesses. This kind of HBP is called secondary hypertension, and it is often cured once the original medical problem is cured. Most HBP, however, is essential or primary hypertension. This kind cannot be cured but can be kept under control by regular, ongoing treatment. 1
