Gout starts when uric acid builds up in your blood and forms crystals in your joints
Gout happens when uric acid—a waste product your body makes when it breaks down purines (compounds found in food and your cells)—accumulates faster than your kidneys can filter it out. When uric acid levels stay high, needle-shaped crystals form inside joints, usually starting in the big toe. Your immune system treats these crystals as invaders, triggering sudden inflammation, pain, redness, and swelling. This acute attack can last days to weeks if untreated.
You don't develop gout overnight. High uric acid levels build silently over months or years before the first attack. Some people have elevated uric acid their whole lives and never get gout; others have a single attack and then years pass before another. The difference lies in what causes your uric acid to spike and whether crystals actually form in your joints.
Key Takeaways
- Gout develops when uric acid accumulates in your blood and forms crystals in joints, usually triggered by diet, genetics, certain medications, or kidney problems.
- Foods high in purines—red meat, organ meats, seafood, and alcohol—raise uric acid levels and can trigger attacks in people prone to gout.
- Men are more likely to develop gout than women, and risk increases with age, obesity, high blood pressure, and kidney disease.
- A single gout attack does not mean you have chronic gout; some people have one episode and never experience another.
- Uric acid levels can be measured with a blood test, and lowering them through diet, weight loss, or medication can prevent future attacks.
Why some people's bodies produce or retain too much uric acid
Your kidneys normally filter out about two-thirds of the uric acid your body produces each day. Gout develops when either your body makes too much uric acid or your kidneys don't filter it efficiently—or both. Genetics play a large role: if your parents or siblings had gout, your risk is significantly higher because kidney function and how your body processes purines are partly inherited.
Kidney disease is one of the strongest risk factors. When your kidneys don't work well, uric acid backs up in your bloodstream. High blood pressure and diabetes also damage kidney function over time, raising gout risk. Certain medications—including diuretics (water pills) used for high blood pressure and low-dose aspirin—can interfere with how your kidneys clear uric acid. Chemotherapy drugs used for cancer can cause a sudden spike when tumor cells break down rapidly.
Foods and drinks that raise uric acid levels
Purines are present in all foods, but some contain far more than others. Red meat, organ meats (liver, kidney, tongue), and certain seafood—especially anchovies, sardines, mussels, and scallops—are high-purine foods that can trigger attacks in people prone to gout. Poultry and fish like salmon and tuna are moderate in purines and usually tolerated better.
Alcohol, especially beer, raises uric acid in two ways: it increases production and slows kidney excretion. A single beer or cocktail can trigger an attack in someone with a history of gout. Sugary drinks and foods high in high-fructose corn syrup also raise uric acid levels. Dehydration concentrates uric acid in your blood, so not drinking enough water increases risk. Fasting or rapid weight loss can trigger attacks because the body breaks down tissue quickly, releasing purines.
Medical conditions and medications that increase gout risk
Beyond kidney disease, several conditions make gout more likely. Metabolic syndrome—a cluster of high blood pressure, high blood sugar, excess belly fat, and abnormal cholesterol—raises uric acid. Psoriasis and other inflammatory skin conditions are linked to higher uric acid levels. Thyroid disorders and parathyroid disease can affect how your body handles uric acid. Leukemia and lymphoma patients face high gout risk, both from the disease itself and from chemotherapy.
Medications that increase gout risk include thiazide diuretics and loop diuretics (used for high blood pressure and heart failure), low-dose aspirin (used to prevent heart attack or stroke), and immunosuppressants taken after organ transplant. Niacin supplements and some HIV medications also raise uric acid. If you take any of these and have gout symptoms, talk to your doctor about whether the medication is necessary or if an alternative exists—do not stop taking it on your own.
Why men, older adults, and people with obesity are at higher risk
Men develop gout three to four times more often than women, partly because testosterone may help the kidneys excrete uric acid more efficiently. Women's risk rises after menopause, when estrogen levels drop. Gout is rare before age 30 in men and before age 50 in women, but risk climbs steadily with age as kidney function naturally declines.
Obesity increases gout risk because excess body weight raises uric acid production and can impair kidney function. Weight loss—even 5 to 10 percent of body weight—can lower uric acid levels and reduce attack frequency. People with a BMI over 30 have roughly double the gout risk of those with a normal BMI.
The difference between a single attack and chronic gout
One gout attack does not automatically mean you have chronic gout or will have another. About 60 percent of people who experience a first attack will have a second within a year, but some go years or never have another. Whether you develop recurrent gout depends on whether your uric acid level stays elevated and whether crystals remain in your joints.
If attacks become frequent—more than two per year—or if you develop tophi (deposits of uric acid crystals under the skin), you have chronic tophaceous gout. At that point, doctors typically recommend long-term uric acid-lowering medication to prevent joint damage. A single attack, by contrast, is usually treated with anti-inflammatory medication to ease pain and swelling, then monitored to see if another occurs.
How to lower uric acid and reduce attack risk
If you've had a gout attack or a blood test shows high uric acid, several changes can lower your levels. Limit high-purine foods, especially red meat and organ meats. Cut back on alcohol, particularly beer. Drink plenty of water—at least 2 to 3 liters daily—to help your kidneys flush uric acid. Lose weight gradually if you're overweight, because rapid weight loss can trigger attacks.
If diet and lifestyle changes don't lower uric acid enough, medications can help. Allopurinol and febuxostat reduce uric acid production. Probenecid helps your kidneys excrete more uric acid. Pegloticase breaks down uric acid directly, used only for severe cases. Your doctor will check your uric acid level with a blood test and adjust medication to keep it below 6 mg/dL, the point at which crystals typically dissolve. Starting uric acid-lowering medication requires care: it can trigger an attack initially, so doctors often prescribe anti-inflammatory medication at the same time.
Frequently Asked Questions
Can you have high uric acid without getting gout?
Yes. Many people have elevated uric acid levels their entire lives and never develop gout. Whether you get gout depends on whether crystals actually form in your joints, which varies by person. A blood test can show high uric acid, but that alone doesn't mean you'll have an attack.
Is gout hereditary?
Gout has a strong genetic component. If your parents or siblings had gout, your risk is higher because kidney function and how your body processes purines are partly inherited. However, genetics alone don't may provide you'll develop gout—diet, weight, medications, and other conditions also matter.
Can you get gout from eating too much fruit?
Most fruits are low in purines and safe for people with gout. However, fruits high in fructose—including dried fruits, fruit juices, and some tropical fruits—can raise uric acid levels. Whole fruits are generally better than juices because they contain fiber and less concentrated sugar.
Does gout go away on its own?
A single gout attack will resolve on its own within days to weeks, even without treatment, though pain and swelling are severe during that time. Anti-inflammatory medication speeds recovery. However, if your uric acid level remains high, future attacks are likely unless you make dietary changes or take uric acid-lowering medication.
Can you prevent gout if you're at high risk?
Yes. If you have a family history of gout, high uric acid on a blood test, or conditions like kidney disease, you can reduce your risk by limiting high-purine foods, staying hydrated, maintaining a healthy weight, and limiting alcohol. If you've had one attack, your doctor may recommend uric acid-lowering medication to prevent recurrence.
