What does nephrologist mean?
A nephrologist is a medical doctor who specializes in nephrology, the branch of medicine concerned with the kidneys. Nephrologists diagnose and treat kidney diseases and related disorders, including conditions that impair kidney function or disrupt fluid and electrolyte balance. They also work with patients who have conditions increasing the risk of kidney damage, particularly long-term diabetes and high blood pressure. A person may be referred to a nephrologist by another physician when kidney disease requires specialist evaluation or ongoing management. In less formal contexts, the term is sometimes replaced by the plainer “kidney doctor.” The word is used in both British and American English, with a predictable difference in the stressed vowel between the two varieties. Although nephrology overlaps with urology, the specialties differ: nephrology focuses specifically on the kidneys, while urology covers the wider urinary tract.
