According to the United States Centers for Disease Control and Prevention, high blood pressure is the second leading cause of kidney failure, second only to diabetes.

High blood pressure is often marked with a consistent systolic blood pressure of at least 140 and a consistent diastolic blood pressure of at least 90. Kidney issues, specifically kidney disease, can be marked by a number of symptoms, but many people who are suffering from kidney disease have no noticeable symptoms. Kidney disease can be diagnosed after performing urine tests, which can include a dipstick test for albumin or a test to measure urine albumin-to-creatinine ratio, and blood tests.
