Signs and Symptoms
Occasionally high blood pressure causes headaches, but in most cases there are no symptoms until it begins to damage body organs. For this reason hypertension is sometimes referred to as the “silent killer,” quietly increasing the risk of developing stroke, heart disease, heart attack, kidney damage, and blindness. Very high blood pressure may cause breathlessness, blurred or double vision and nose bleeds as well as a persistent headache.
Because hypertension is both a quiet and a common condition, blood pressure is often measured each time a patient sees their doctor. Nearly a third of UK residents with high blood pressure do not know about it and are not being treated.
