What is the primary specialty of a nephrologist?

A nephrologist specializes primarily in kidney diseases. This includes the diagnosis and treatment of various conditions affecting the kidneys, including chronic kidney disease, renal failure, kidney stones, hypertension related to kidney problems, and electrolyte imbalances. They also manage patients on dialysis and those who require kidney transplants.

Given that the other options pertain to different specialties—cardiac health relates to cardiology, neurological disorders are the focus of neurology, and gastrointestinal disorders are managed by gastroenterologists—it highlights the specific focus of nephrologists on the kidneys. Understanding these distinctions emphasizes the critical role nephrologists play in managing renal health and underscores the importance of their expertise in addressing complex kidney-related issues.
