A blood pressure that is above the normal range of 120/80 mm Hg is called high blood pressure. Our blood pressure keeps changing throughout the day. However, a blood pressure consistently higher than normal is diagnosed as high blood pressure. Constant high blood pressure has the intrinsic potential to develop into a serious health crisis. It can cause critical health issues, such as heart attack, stroke, impaired vision, brain hemorrhage, kidney failure, and other complications.  However, you can avoid these complications by bringing certain changes in your lifestyle, eating healthy foods, being physically active, and limiting the use of salt, cigarettes, and alcohol, etc.
