Gout and Kidney Disease: Why the Connection Matters

Gout isn't just about painful joints. Your kidneys play a critical role in managing uric acid, and protecting kidney health should be part of a long-term gout management strategy.

Research suggests that approximately 90% of people with gout have reduced ability to excrete uric acid. When the kidneys cannot remove enough uric acid, levels can rise in the bloodstream, contributing to crystal formation, painful gout attacks, and an increased risk of kidney stones.

The relationship also works both ways. Reduced kidney function can make it harder to eliminate uric acid, while gout and elevated uric acid levels are frequently associated with chronic kidney disease (CKD).

Recent research has also linked uncontrolled gout with a greater risk of developing chronic kidney disease and higher mortality compared with controlled gout. Although these findings do not establish that gout directly causes these outcomes, they reinforce the importance of effective uric acid management.

Know Your Uric Acid Target

For most people with gout, medical guidelines recommend maintaining a serum urate level below 6 mg/dL to help prevent uric acid crystal accumulation and reduce future flares.

If you have gout, particularly alongside kidney disease, speak with your nephrologist or primary care physician about monitoring your uric acid levels and developing a comprehensive management plan.

The takeaway: Managing gout means thinking beyond your next flare. Understanding your uric acid levels, working with your healthcare provider, and taking a proactive approach to kidney health are important steps toward long-term wellness.
