What should you know about gout and kidney disease?

Gout happens when urate crystals trigger inflammation in a joint. The kidneys help remove urate from the body, so reduced kidney function can make urate harder to clear. Repeated gout attacks and some urate-related stones may also place extra strain on the urinary system. Having kidney disease does not prove that every painful joint is gout, and a gout flare does not by itself show that kidney function has worsened.

Your clinician may check kidney function, urate, urine symptoms and the pattern of attacks. The treatment dose and choice may need adjustment when kidney function is reduced. Some pain medicines are unsuitable for certain people with kidney disease, dehydration or other health conditions.

Keep a current list of prescriptions, over-the-counter pain medicines and supplements. Take prescribed urate-lowering treatment consistently if it has been recommended, and do not change the dose during a flare unless your clinician tells you to. Follow your personalised fluid advice: drinking more is not appropriate for everyone with kidney disease. Limiting alcohol, avoiding crash diets and choosing a balanced eating pattern may reduce avoidable triggers. Weight management can also support gout care when obesity is present.

Get urgent help for a swollen joint with fever, chills or marked illness, or for severe flank pain with vomiting or difficulty passing urine. Contact your care team promptly if urine output changes, swelling rapidly develops, or a new medicine causes a concerning reaction. Arrange review for recurrent attacks, because prevention and kidney monitoring may need to be adjusted together.

Ask how often kidney function and urate should be checked, which pain-relief options fit your kidney health, and whether any current medicine can raise urate or affect kidney function.
