How insulin helps kidneys hold onto salt and uric acid
Effect of insulin on uric acid excretion in humans.

Surprising Findings
Insulin reduces uric acid excretion without changing blood uric acid levels.
Most would expect reduced excretion to raise blood levels, but serum uric acid stayed constant—suggesting other compensatory mechanisms may be at play.
Practical Takeaways
Managing insulin levels through diet and lifestyle may help reduce gout risk and support healthy blood pressure by improving kidney handling of uric acid and sodium.

In healthy people, how much uric acid their kidneys get rid of tends to go up when the amount of sodium they pee out also goes up — and this happens both normally and when insulin levels are high, suggesting the kidneys might use the same system to handle both.
When healthy adults have higher insulin levels, their bodies temporarily excrete less uric acid in the urine — meaning insulin might help control uric acid levels in the short term.
When healthy adults have higher-than-normal insulin levels, their kidneys hold onto more salt — about 30% less salt ends up in their pee, which shows insulin can quickly affect how the kidneys handle sodium.
When insulin lowers how much uric acid and sodium your kidneys get rid of, these two changes tend to happen together in healthy adults — meaning insulin might be affecting both in a similar way.
When insulin levels go down, your kidneys get rid of more water and salts, so you need to drink fluids with minerals to stay hydrated.
