Diabetic kidney disease is kidney damage caused by diabetes that affects the organs’ ability to filter waste from the blood. Dr. Joshi provides comprehensive care for patients in San Mateo County, including medication management, blood pressure control, dietary guidance, and monitoring of kidney function. Dr. Joshi works closely with patients to slow disease progression and preserve kidney health through individualized treatment plans tailored to each patient’s specific needs.
What is diabetic kidney disease?
Diabetic kidney disease, also called diabetic nephropathy, happens when high blood sugar levels from diabetes damage the tiny filters inside the kidneys. These filters, called nephrons, normally clean waste and extra fluid from the blood. When diabetes is not well controlled over time, the high sugar levels can harm these filters. The kidneys may start to leak protein into the urine and lose their ability to remove waste properly. This condition develops slowly, often over many years. In San Mateo County, Dr. Joshi helps patients understand how diabetes affects kidney health. Early detection and treatment can help slow down the damage. Without proper care, diabetic kidney disease can progress to kidney failure, which may require dialysis or transplant. Managing blood sugar levels is the most important step in protecting the kidneys from diabetes-related damage.
Signs and symptoms

- Foamy or bubbly urine indicating protein leakage
- More frequent urination, especially at night
- Fatigue and weakness that does not improve with rest
- Nausea, vomiting, or loss of appetite
- Difficulty concentrating or confusion

How Dr. Joshi manages diabetic kidney disease
Dr. Joshi takes a comprehensive approach to treating diabetic kidney disease in Burlingame and Daly City. The treatment plan begins with a thorough evaluation of kidney function through blood tests, urine tests, and assessment of overall health. Dr. Joshi works with each patient to optimize blood sugar control, as maintaining healthy glucose levels is essential for slowing disease progression. Blood pressure management is another critical component, and Dr. Joshi may prescribe medications that protect the kidneys while controlling blood pressure. Dietary modifications play an important role, and Dr. Joshi provides guidance on protein, sodium, and potassium intake based on the stage of kidney disease. Dr. Joshi monitors kidney function regularly through lab work to track changes over time. For patients in San Mateo County, Dr. Joshi coordinates care with endocrinologists and primary care physicians to ensure a team-based approach. When appropriate, Dr. Joshi discusses advanced treatment options, including preparation for dialysis or kidney transplant evaluation. The goal is always to preserve kidney function for as long as possible while maintaining quality of life.

- Blood tests show declining kidney function or elevated creatinine levels

Frequently asked questions
Can diabetic kidney disease be reversed?
Diabetic kidney disease cannot typically be reversed, but its progression can be slowed or stopped with proper treatment. Dr. Joshi focuses on protecting remaining kidney function through blood sugar control, blood pressure management, and lifestyle modifications. Early intervention provides the best outcomes for preserving kidney health.
How often should I see a diabetic kidney disease doctor in the Bay Area?
The frequency of visits depends on the stage of kidney disease and how well controlled your diabetes and blood pressure are. Dr. Joshi may recommend appointments every three to six months for monitoring, or more frequently if kidney function is declining or treatment adjustments are needed.
What medications does Dr. Joshi prescribe for diabetic kidney disease?
Dr. Joshi may prescribe medications that protect the kidneys, such as ACE inhibitors or ARBs, which help control blood pressure and reduce protein loss. Your physician will determine the appropriate medications based on your kidney function, blood pressure, and overall health status.
Will I need dialysis if I have diabetic kidney disease?
Not all patients with diabetic kidney disease will need dialysis. With early detection and proper management, many patients can maintain kidney function for years. Dr. Joshi works to slow disease progression and will discuss dialysis only if kidney function declines to a level where it becomes necessary.
What diet changes help with diabetic kidney disease?
Dr. Joshi may recommend limiting protein, sodium, potassium, and phosphorus depending on your kidney function stage. A registered dietitian can help create a meal plan that supports both diabetes management and kidney health. Dietary needs change as kidney disease progresses.
Does insurance cover treatment for diabetic kidney disease?
Most insurance plans, including Medicare, cover nephrology care for diabetic kidney disease. Dr. Joshi’s office in San Mateo County can verify your specific coverage and help with insurance questions before your appointment. Treatment is considered medically necessary care.
