High Uric Acid Symptoms: Causes, Signs & What to Do
High uric acid causes gout attacks, kidney stones, and joint damage with recurrent episodes. This page covers the specific symptoms, likely causes, normal ranges, and when to act.
High uric acid (hyperuricemia) is often asymptomatic for years before a gout attack, but the first attack is unmistakable — sudden, severe joint pain that often peaks within 24 hours. Without treatment, episodes become more frequent, affect more joints, and can cause permanent joint destruction and kidney disease. See the Uric Acid biomarker overview for how it is measured and what the result means.
What High Uric Acid Means
Uric acid is the end product of purine metabolism. When production exceeds renal excretion, serum urate rises above the saturation threshold (approximately 6.8 mg/dL), and urate crystals can begin to deposit in joints and soft tissue. The immune system recognizes these crystals as foreign and mounts an intense inflammatory response — this is an acute gout attack. Between attacks, urate continues to accumulate silently, and tophi (crystal deposits under the skin) can form with long-term untreated elevation.
Symptoms of High Uric Acid
Between attacks: usually none, even with significantly elevated levels.
Acute gout attack:
- Sudden severe pain in a joint, reaching maximum intensity within 12 to 24 hours
- Most commonly affects the first metatarsophalangeal joint (base of the big toe — called podagra) but also ankles, wrists, knees, and fingers
- Joint is hot, red, swollen, and extremely tender to even light touch
- Fever in some cases
- Spontaneous resolution in 7 to 10 days without treatment, but earlier with NSAIDs or colchicine
Chronic untreated hyperuricemia:
- Tophi — chalky white nodules under the skin of ears, elbows, fingers, and Achilles tendon
- Chronic gouty arthropathy — joint damage from repeated crystal deposition
- Uric acid kidney stones (causing flank pain, blood in urine)
- Chronic kidney disease from urate deposits in renal tissue (urate nephropathy)
What Causes High Uric Acid
- Diet high in purines: red meat, organ meats (liver, kidney), shellfish (anchovies, sardines, mussels)
- Alcohol — particularly beer (contains purines) and spirits
- High fructose intake from sweetened beverages and processed foods
- Obesity and insulin resistance (reduce renal urate excretion)
- Chronic kidney disease (impaired excretion)
- Diuretics, especially thiazides and loop diuretics
- Low-dose aspirin (reduces renal urate excretion)
- Cyclosporine (used in transplant patients)
- Rapid cell turnover states: tumor lysis syndrome, psoriasis, hemolytic anemia
- Genetic factors: Lesch-Nyhan syndrome (rare), familial juvenile gout
Normal Uric Acid Levels
| Group | Reference Range | |---|---| | Men | 3.4-7.0 mg/dL | | Women | 2.4-6.0 mg/dL | | Gout saturation threshold | Above 6.8 mg/dL (urate begins crystallizing) | | Treatment target (if gout) | Below 6.0 mg/dL |
Women have lower uric acid levels due to the uricosuric effect of estrogen — levels often rise after menopause.
When to See Your Care Team
Book a 1:1 consultation with a licensed care team lead after a first gout attack to confirm the diagnosis and assess whether urate-lowering therapy is appropriate. Uric acid above 9 mg/dL, two or more gout attacks per year, tophaceous gout, or uric acid kidney stones are standard indications for medication. Do not start allopurinol during an acute attack — it can prolong the episode.
Frequently Asked Questions
Can I have high uric acid without ever having a gout attack?
Yes. Approximately two-thirds of people with hyperuricemia never develop gout. However, high uric acid is associated with hypertension, cardiovascular disease, and chronic kidney disease independent of gout — elevated levels are worth addressing regardless of joint symptoms.
What triggers a gout attack?
Common triggers include dehydration, alcohol (especially beer), a purine-rich meal, starting or stopping urate-lowering medication too quickly, trauma to a joint, medical illness, or surgery. The attack typically begins at night.
What is the difference between allopurinol and colchicine?
Allopurinol (and febuxostat) are urate-lowering agents — they reduce uric acid production and are used long-term to prevent gout attacks. Colchicine, NSAIDs, and corticosteroids are anti-inflammatory agents used to treat acute attacks. Colchicine does not lower uric acid levels.
Does cherry juice really help gout?
Cherry extract and tart cherry juice have modest evidence for reducing gout attack frequency, possibly through anti-inflammatory anthocyanins and a mild uricosuric effect. They are a reasonable adjunct but not a substitute for urate-lowering therapy in people with recurrent gout.
