High uric acid: causes, gout risk and how to lower it
Short answer
High uric acid (hyperuricemia) is a level above about 7.0 mg/dL in men or 6.0 in women — close to the 6.8 mg/dL point at which urate can crystallize in joints and kidneys. It comes from making more (purine-rich foods, beer and spirits, fructose and sugary drinks, rapid cell turnover) or, more often, from the kidneys excreting less (chronic kidney disease, dehydration, inherited transporter variants, diuretics, low-dose aspirin, insulin resistance). Most people with a high uric acid never develop gout or stones, and guidelines do not recommend medication for a high level alone; gout attacks, uric acid kidney stones or kidney disease are what change that, with a treatment target below 6.0 mg/dL.

When does this result need same-day care?
- A hot, swollen, very painful joint with fever — same-day care; infection in the joint looks like gout and must be excluded
- Severe flank pain with blood in the urine, vomiting or fever — emergency care; a stone may be blocking the kidney
- Uric acid above 10–12 mg/dL with a rising creatinine, especially after chemotherapy — emergency care (tumor lysis syndrome)
What is the normal range for Uric Acid?
- Male, age 18+: 3.40 – 7.00 mg/dL
- Female, age 18+: 2.40 – 6.00 mg/dL
Often reflects gout, kidney issues, certain medications, high purine intake, or alcohol use.

What are the common causes of high Uric Acid?
- Diet and drink — red and organ meats, shellfish, beer and spirits, high-fructose drinks and sweets; each adds modestly, together they add up
- Reduced kidney excretion — chronic kidney disease, dehydration, and common inherited variants in urate transporters (the largest single factor in most people)
- Medications — thiazide and loop diuretics, low-dose aspirin, cyclosporine and tacrolimus, pyrazinamide and ethambutol, niacin, some chemotherapy
- Metabolic syndrome — obesity, insulin resistance, high blood pressure and high triglycerides travel with high uric acid
- Rapid cell turnover — psoriasis, hemolysis, myeloproliferative disorders, and tumor lysis after chemotherapy
- Fasting, crash dieting and ketogenic diets — ketones compete with urate for excretion; uric acid often rises in the first weeks
- Hypothyroidism, hyperparathyroidism and lead exposure
- Rare inherited enzyme disorders (Lesch–Nyhan syndrome, PRPP synthetase overactivity) — usually evident from childhood
What symptoms go with high Uric Acid?
- None in most people — hyperuricemia is usually silent
- Gout: sudden, severe pain, swelling, redness and warmth in a joint — classically the big toe, also the midfoot, ankle or knee — often starting at night
- Firm lumps under the skin (tophi) around joints or on the ear after years of untreated gout
- Kidney stones: severe flank pain that comes in waves, blood in the urine, nausea
What do clinicians usually check next?
- Repeat when well — uric acid can read normal during a gout flare and high after a heavy meal or alcohol; recheck two or more weeks after an attack and off diuretics if possible
- Kidney function (creatinine, eGFR) and a urinalysis
- A metabolic screen — A1c, lipids, blood pressure and weight — because hyperuricemia clusters with metabolic syndrome and the same changes lower both
- Medication review with the prescriber: diuretics, low-dose aspirin, immunosuppressants
- A 24-hour urine uric acid when stones are recurrent, to separate over-production from under-excretion
- Joint fluid analysis for urate crystals when the diagnosis of gout is unclear, and ultrasound or dual-energy CT for suspected tophi
- If urate-lowering therapy is started (allopurinol, febuxostat): target under 6.0 mg/dL (under 5.0 with tophi), check kidney function and, in people of Han Chinese, Thai or Korean ancestry with kidney disease, HLA-B*58:01 before allopurinol
For gout treated with urate-lowering therapy, the American College of Rheumatology recommends treating to a serum urate below 6 mg/dL, checking levels every 2–5 weeks while the dose is being adjusted and about every 6 months once stable. Without gout, there's no routine retest interval.
How do you recheck Uric Acid?
Prices are cash-pay; every order adds one $6 lab processing fee. Physician authorization is included; no insurance or referral needed.

Common questions
Do I need treatment for a high uric acid without gout?
Generally not. Guidelines do not recommend medication for asymptomatic hyperuricemia. Diet, alcohol and weight changes lower it, kidney function is monitored, and treatment starts if gout, tophi, uric acid stones or kidney disease develop.
What uric acid level causes gout?
Urate starts to crystallize above about 6.8 mg/dL, and gout risk rises with every point above 7. But most people above 7 — even above 9 — never have an attack; genetics, kidney function, alcohol and how fast the level changes all matter. Gout is diagnosed by the joint, not the number.
How can I lower uric acid naturally?
Weight loss, less beer and spirits, cutting sugary drinks and fructose, moderating red meat and shellfish, and good hydration each lower it by a fraction of a point; low-fat dairy, coffee and 500 mg of vitamin C help modestly. Together these can bring a level of 7–8 under 7, but established gout usually needs medication to reach the target.
Can dehydration raise uric acid?
Yes — less fluid means less urate excreted and a more concentrated blood sample. A hot day, a hard workout or a night without fluids before the draw can add a point. Repeat well hydrated before acting on one value.
Is high uric acid bad for my kidneys?
Very high levels can form stones and, rarely, damage the kidney directly; hyperuricemia also accompanies chronic kidney disease because the kidney excretes less. Whether lowering uric acid protects kidney function in people without gout is unsettled, so guidelines focus on treating gout and stones rather than the level alone.
Do I need to fast for a uric acid test?
Fasting is not required, but a large purine-rich meal or alcohol in the previous 24 hours can raise the result. Test under ordinary conditions, well hydrated, and not during a gout flare.
