Types of Hypertension:
- 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.
