Why I Built Kidney Compass

I was born with a congenital urinary tract obstruction that caused bilateral hydronephrosis. I've lived with chronic kidney disease my entire life — and at 40, I'm now in Stage 4.

Over the years, I had hundreds of questions about my condition. What do my lab results actually mean? What should I eat? When does dialysis or transplant become real? Most of the information I found was either too clinical or too vague to be useful.

Kidney Compass is the resource I wish I had earlier — plain-language explanations, practical guidance, and honest information for patients and families navigating the same path.

Frequently Asked Questions

Quick answers to common questions about kidney disease and this site.

What is chronic kidney disease (CKD)?

Chronic kidney disease means your kidneys are damaged and gradually losing their ability to filter waste from your blood. It is divided into five stages based on your GFR. Many people live with early-stage CKD for years without symptoms.

What does GFR mean?

GFR stands for glomerular filtration rate. It measures how well your kidneys filter waste, reported in mL/min. A normal GFR is around 90 or above. Below 60 for three months may indicate CKD.

What foods should kidney patients avoid?

Depending on your stage and lab results, you may need to limit sodium, potassium, phosphorus, and protein. Common foods to watch include processed meats, bananas, oranges, dairy products, and high-sodium packaged foods. Your dietitian can tailor a plan to your needs.

What is the difference between dialysis and transplant?

Dialysis filters your blood when your kidneys can no longer do so and must be done regularly. A kidney transplant replaces a failed kidney with a healthy donor kidney. Both sustain life — the best choice depends on your health, lifestyle, and preferences.

Is this medical advice?

No. Kidney Compass provides educational information only. Content is written from a patient perspective to help you understand your condition, but it is not a substitute for professional medical advice. Always consult your physician.
