The kidneys excrete unwanted water and salts from the body into the urine.High blood pressure is a common condition that, if left untreated, can damage the brain, heart, blood vessels, kidneys, and other parts of the body. It can cause seizures, heart failure, stroke, kidney failure, vision loss, and other problems.In addition to taking medications, lifestyle changes can also help control blood pressure. These changes include a low-fat and low-salt diet, a healthy weight, at least 30 minutes of exercise most days, no smoking, and moderate drinking.
