7.Kidney Failure
High blood pressure is the second-leading cause of kidney failure. It narrows and hardens the blood vessels your kidneys use to help get rid of waste and extra fluid. That keeps special filters, called nephrons, from getting enough blood and nutrients. That can eventually shut down your kidneys for good.
8.Eye Problems
Over time, high blood pressure can slow blood flow to the retina, the light-sensitive layer of tissue at the back of the eyeball. It can also slow the travel of blood to the optic nerve, which helps send signals to your brain. Either may blur your vision, or in some cases make it go away. HBP might also cause fluid to build under your retina. That could scar the tissue and distort your vision.
