This pressure puts extra strain on your blood vessels, heart and other organs, such as the brain, kidneys and eyes. Over time, it can increase your risk of a number of serious and potentially life-threatening health conditions, such as heart disease. If experiencing swollen ankles, it could indicate your risk of not only high blood pressure but of heart failure.
