Understanding gout

What causes gout—and what can set off a flare?

Prepared 2026-10-29 · Read as Markdown

Gout starts with urate crystals, but the reasons urate builds up vary. Your body may produce too much, remove too little, or both. Genetics, kidney function, medicines, and other health conditions can all play a part. You can develop gout without heavy drinking or an unusually rich diet. [S06]

Body cells and food contribute purines, which lead to blood urate; separate arrows show kidney and other removal routes, with a conditional crystal-formation note.

Look at the whole picture

A clinician may ask about gout in your family, kidney disease, blood pressure, diabetes, metabolic health, and conditions that increase cell turnover. Age and sex-related factors matter too: gout is more common in men and becomes more common in women after menopause. Younger adults can also have it. These patterns help build a history; they do not decide who deserves an assessment. S06

Where food and alcohol fit

Alcohol, sugary drinks, and large amounts of animal-source purines are worth discussing. Changes may support treatment, but they do not remove genetic or kidney-related susceptibility. The American College of Rheumatology’s lifestyle recommendations are generally conditional, and a single food change often has a modest effect on blood urate. S02

Check medicines without stopping them yourself

Some diuretics, low-dose aspirin, high-dose niacin, and certain immune-suppressing medicines can affect urate. The reason you take them still matters. ACR conditionally supports switching hydrochlorothiazide or choosing losartan when feasible, but advises against stopping low-dose aspirin prescribed for an appropriate reason. Bring the full list to your prescriber rather than crossing things off yourself. S02 S06

A trigger is not the whole cause

Illness, injury, dehydration, alcohol, a large meal, or changes in urate-lowering treatment may precede a flare. Recording the timing can help a conversation. One meal followed by pain does not prove that meal caused it; the existing crystal deposits and your individual susceptibility matter as well. S02 S08
