High blood pressure also increases your risk of diabetic eye disease. As dangerous as high blood pressure can be, you may have no symptoms. That's why it's important to find out whether or not you have high blood pressure. If it's high, you should do all you can to lower it. If it's normal, you should strive to keep it so.
Blood pressure is a measure of the force of the circulating blood against the walls of the arteries.
If you have high blood pressure, your arteries have an increased resistance to the flow of blood. Your heart has to pump harder than it should to get blood to all parts of your body. High blood pressure is classified by degrees. The higher your blood pressure, the greater your risk for stroke, heart disease, and kidney and eye disease. As you get older, your risk of high blood pressure increases.
