High blood pressure is often known as ‘the silent killer’, because it rarely has any noticeable symptoms.
But, if you have extremely high blood pressure, you might develop a pounding in your chest, find blood in your urine, or have difficulty breathing.
You should speak to a doctor if you’re worried about the warning signs of hypertension, or if you think you may be at risk.
Everyone over 40 years old should check their blood pressure at least once every five years.
