What is nephrology care?
Nephrology care focuses on the diagnosis and management of kidney diseases and conditions affecting kidney function. The kidneys are vital organs that filter waste products from the blood, regulate fluid balance, control blood pressure, and produce hormones that affect other body systems. When kidneys do not work properly, waste can build up in the body and cause serious health problems. A nephrologist is a physician who specializes in treating kidney disorders, from early-stage kidney disease to advanced kidney failure. Dr. Joshi evaluates patients with abnormal kidney function tests, high blood pressure that may be kidney-related, electrolyte imbalances, and other conditions affecting the kidneys. Nephrology care may include medication management, dietary counseling, and monitoring of kidney function over time to slow disease progression.

How Dr. Joshi manages nephrology conditions
Dr. Joshi begins with a thorough evaluation that may include reviewing medical history, conducting a physical examination, and ordering laboratory tests to assess kidney function. Blood tests can measure creatinine levels, estimated glomerular filtration rate, and electrolyte balance. Urine tests may help identify protein loss or other abnormalities. Based on these findings, Dr. Joshi develops an individualized care plan that addresses the underlying cause of kidney dysfunction. Treatment approaches may include medications to control blood pressure, manage diabetes, or reduce protein in the urine. Dr. Joshi provides guidance on dietary modifications that can support kidney health, such as limiting sodium, potassium, or phosphorus depending on the specific condition. For patients with progressive kidney disease, Dr. Joshi monitors kidney function regularly and discusses treatment options including dialysis or transplant evaluation when appropriate. Dr. Joshi coordinates care with primary care physicians and other specialists to ensure comprehensive management of conditions affecting the kidneys.
