Blood pressure is written as two numbers. The top number, systolic pressure, reflects pressure when the heart beats. The bottom number, diastolic pressure, reflects pressure when the heart rests between beats. Both numbers matter.
CDC explains that normal blood pressure is less than 120/80 mm Hg, while high blood pressure is consistently at or above 130/80 mm Hg. One high reading does not automatically mean hypertension, but repeated readings deserve attention.
Home monitoring can help when it is done correctly. Sit quietly, support your arm, use a properly sized cuff, and record readings with the date and time. Bring the log to your clinician rather than trying to interpret every number on your own.
High blood pressure often has no symptoms, yet it increases risk for heart disease and stroke. Treatment may include nutrition changes, physical activity, limiting alcohol, improving sleep, reducing sodium, medication, or a combination based on individual risk.
Quick Takeaways
- Repeated readings matter more than one isolated number.
- Use a correctly sized cuff and record dates.
- Discuss persistent readings at or above 130/80 mm Hg with a clinician.
