Key points

  • High blood pressure often has no symptoms.
  • The diagnosis is not made only on the basis of one home measurement.
  • Prescribed therapy should not be interrupted or shared with others.

Why measurement matters

Blood pressure is recorded as two values: the first describes the pressure when the heart contracts, and the second when it relaxes. Values ​​are interpreted together with age, other diseases, medications and method of measurement.

The World Health Organization states that most people with hypertension have no symptoms. Regular and correct measurement is therefore more important than relying on feeling.

How to keep a useful journal

Measure in peace, according to the device's instructions, and write down the date, time and both values. Show the diary to the family doctor. He can assess whether a repeated home or outpatient measurement and additional tests are needed.

  • do not change therapy based on one result
  • write down the complaints that occurred with the measurement
  • make sure the cuff is the right size

What helps in the long run

Less salt, more exercise, quitting smoking, eating a balanced diet and taking prescribed medication can reduce the risk. The plan should be adapted to your health condition.

Very high blood pressure with chest pain, shortness of breath, confusion, sudden weakness, vision changes, or severe headache requires immediate medical evaluation.
