Normal blood pressure is generally defined as a systolic pressure of less than 120 mmHg and a diastolic pressure of less than 80 mmHg (120/80 mmHg).
Normal blood pressure indicates a healthy cardiovascular system and does not require medication.
Hypertension is defined as a systolic pressure of 140 mmHg or higher and/or a diastolic pressure of 90 mmHg or higher without the use of antihypertensive medications.
Hypertension is classified into three stages: Stage 1 (mild), Stage 2 (moderate), and Stage 3 (severe), based on blood pressure readings.
Hypotension is typically defined as blood pressure below 90/60 mmHg, but this threshold may not be applicable to everyone, as some individuals naturally have lower blood pressure.
For some, hypotension may be normal, but for others, it may cause symptoms such as dizziness and weakness.
Blood pressure naturally fluctuates throughout the day, usually higher in the morning and lower at night.
It can also be influenced by emotions, physical activity, diet, and alcohol consumption.
The correct method for measuring blood pressure is to sit in a quiet environment, with your arm resting on a table at heart level.
Multiple measurements should be taken to obtain an accurate blood pressure reading.
For most people, the goal is to keep blood pressure below 140/90 mmHg.
For patients with heart disease, diabetes, or chronic kidney disease, stricter blood pressure control targets may be necessary.
