Blood Pressure
Measure it properly at home — technique changes the number.
High blood pressure has no symptoms until it has already caused damage. Technique matters as much as the device: sit with your back supported and feet flat, rest five minutes, keep the cuff at heart height, and do not talk during the reading.
Take two readings a minute apart, morning and evening, and use the average. A single high reading is not a diagnosis — patterns over a week are what your doctor needs.
When to see a doctor
Seek same-day medical attention for a reading above 180/120, or any reading with chest pain, severe headache, visual change, weakness or breathlessness.
