High blood pressure symptoms, signs and risks. High blood pressure, or hypertension, doesnât usually cause any obvious symptoms. The British Heart Foundation estimates that up to 5 million people in the UK have undiagnosed high blood pressure. Left untreated, hypertension can lead to serious diseases, including stroke, heart disease, kidney failure and eye problems.
