There are two types of kidney failure:
1. Acute ( Now called Acute Kidney Injury or AKI )
2. Chronic ( Now called Chronic Kidney Disease or CKD )
AKI is a temporary decline in kidney function which can most often be corrected. AKI may by caused by severe infections, extensive burns, severe diarrhea or vomiting, chemical or drug poisoning, surgery, injury or blockage of the kidneys. In most cases when the source of the problem is eliminated, normal kidney function resumes.
CKD, on the other hand, is a permanent condition, meaning that once it occurs, the kidneys cannot be made to function again.CKD may be the result of heredity, as with Polycystic Kidney Disease, or may be caused by prolonged medical conditions, such as high blood pressure or diabetes. Persons with severe chronic kidney disease are referred to as having End Stage Renal Disease (ESRD). This term indicates that the patient must now rely on some type of medical treatment to help replace the loss of kidney function.
