How is kidney function monitored on GLP-1?

Kidney function on a GLP-1 is usually followed through three values on the basic metabolic panel: creatinine, eGFR (estimated kidney filtration rate), and BUN. Some clinicians add a urine albumin-to-creatinine ratio to catch early protein leak, particularly in type 2 diabetes. Many people see kidney markers stay steady or improve once blood sugar is better controlled. A short rise in creatinine during heavy nausea or low fluid intake is often dehydration rather than kidney damage, but anything that worries you is a question for your doctor, who decides what to monitor. Phaze trends creatinine, eGFR, and BUN with your dose overlaid so a longer change stands apart from a one-week dip during a rough side-effect stretch.
