Uric Acid

High uric acid (hyperuricemia) can cause gout—uric crystals deposit in joints, producing sudden severe pain, redness and swelling, often in the big toe. It raises risk of kidney stones and can contribute to chronic kidney disease. Long-term elevation may form tophi (crystal lumps) and cause joint damage, and is linked with higher cardiovascular and metabolic risk; many people are initially asymptomatic.

Lower uric acid by losing weight gradually, drinking plenty of water, and cutting high‑purine foods (red meat, organ meats, shellfish), plus alcohol—especially beer—and sugary/fructose drinks. Eat low‑fat dairy, more vegetables, whole grains and cherries. Avoid crash diets and stay active. If levels remain high or you have gout, see your doctor—prescription urate‑lowering drugs (e.g., allopurinol) may be recommended.

The best drink to help control uric acid is plenty of water to dilute urine and promote excretion. Low fat dairy and moderate coffee consumption are linked to lower uric acid and reduced gout risk. Tart cherry juice may help prevent flares for some people. Avoid sugary sodas and alcohol (especially beer), which raise uric acid. Aim for consistent hydration and moderation.

Normal adult serum uric acid levels are generally: men ~3.4–7.0 mg/dL (200–416 µmol/L) and women ~2.4–6.0 mg/dL (143–357 µmol/L). Reference ranges can vary slightly by laboratory, age, pregnancy and testing method. Persistently higher or lower values warrant medical evaluation to assess causes such as gout, kidney function or metabolic disorders.

The kidneys are the main organs affected by uric acid. Kidneys filter and excrete uric acid; when levels rise, crystals can form causing kidney stones, obstruction, inflammation and progressive kidney damage or reduced function. High uric acid also causes crystal deposition in joints (gout), but renal handling and the risk of stones or chronic kidney disease make the kidneys especially vulnerable.

Foods that raise uric acid include organ meats (liver, kidneys), red meats (beef, lamb, pork), certain seafood (anchovies, sardines, mackerel, scallops, shellfish), sugary foods and drinks (especially fructose or high‑fructose corn syrup), processed meats, and alcohol—particularly beer. Frequent or large intake, obesity, dehydration, and rapid weight gain further increase uric acid levels.
