Nephrology is the branch of Internal Medicine that studies the function and diseases of the kidney and related organs. A nephrologist specializes in diagnosing and treating problems with kidneys, high blood pressure, fluid retention, and electrolyte imbalance.
Some diseases such as diabetes pose a threat to healthy kidney function. A nephrologist may be consulted to treat patients whose kidney function is compromised by disease. Their expert insight into these vital organs leads to better diagnosis and treatment.
