About Nephrologist Speciality
A nephrologist is a trained medical professional who diagnoses and treats diseases related to the kidneys in men, women and children. Acute renal failure, chronic kidney diseases, decline in kidney function, chronic urinary tract infections, repeat urinary tract infections, high blood pressure that does not respond to medication, kidney stones, blood loss in the urine, protein loss in the urine are some of the medical conditions that a nephrologist provides treatment for.
In order to become a certified nephrologist, one must complete graduation from a medical college followed by 3 years of residency in Internal Medicine. After that, nephrologists must complete a two- to three-year fellowship in nephrology. During fellowship, nephrologists learn about glomerular/vascular disorders, tubular/interstitial disorders, hypertension, dialysis, kidney transplantation, mineral metabolism, management of acute kidney failure, management of chronic kidney disease, nutrition and interpretation of x-rays, sonograms and other tests.
