Normal blood pressure for a man is generally anything lower than 120/80. The top number, "120," referred to as systolic pressure, represents the pressure when your heart contracts. The bottom number, "80," referred to as diastolic pressure, represents the pressure when your heart is at rest.
Hypotension (low blood pressure) is different in each individual. If your top number reads less than 120 or your bottom number reads less than 80 and you have symptoms such as dizziness, fainting and chest pain, you may have hypotension.
Prehypertension occurs when the top number is between 120 and 139 or the bottom number is between 80 and 89. Prehypertension should be monitored carefully because it can worsen into hypertension.
Hypertension occurs when the top number reads 140 or higher or the bottom number reads 90 or higher. At this point, your doctor may prescribe medication to help lower your blood pressure.
Special Health Considerations
If you have diabetes or impaired kidney function, hypertension occurs when the top level is 130 or higher or the bottom number is 80 or higher.
Hypertension can occur differently during a man's life. Younger men typically have higher diastolic pressure and older men have higher systolic pressure.
You can prevent or improve high blood pressure by losing weight, exercising regularly and limiting your intakes of sodium and alcohol.
