What gout is and why it happens

Gout is a type of arthritis caused by a buildup of uric acid crystals in your joints. When uric acid levels get too high in your blood, needle-shaped crystals form in and around joints — most often in the big toe, but also in ankles, knees, wrists, and fingers. These crystals trigger sudden, severe inflammation and pain.

Your body makes uric acid when it breaks down purines, which are natural compounds found in many foods and drinks. Normally your kidneys filter uric acid out through urine. But if your kidneys don't work efficiently, or if you consume too much purine, uric acid builds up. Certain medications (like diuretics used for blood pressure), dehydration, alcohol, and foods high in purines — red meat, organ meats, shellfish, and sugary drinks — all raise your risk.

Men are more likely to develop gout than women, and your risk increases with age. If you have a family history of gout, your chances are higher. Being overweight, having high blood pressure, or having kidney disease also puts you at greater risk.

Key Takeaways

  • Gout flare-ups happen suddenly when uric acid crystals form in a joint, causing intense pain, redness, and swelling that usually peaks within 24 hours.
  • During a flare, ice, elevation, and over-the-counter pain relievers like indomethacin or naproxen can reduce pain; prescription medications like colchicine work best if taken early.
  • Between flare-ups, lowering uric acid through diet changes (fewer red meats, organ meats, shellfish, and sugary drinks) and staying hydrated helps prevent future attacks.
  • If you have frequent flare-ups, your doctor may prescribe long-term uric acid-lowering medications like allopurinol or febuxostat to keep levels below the threshold where crystals form.
  • Losing weight, limiting alcohol (especially beer), and managing related conditions like high blood pressure reduce both flare frequency and severity.

Recognizing a gout flare-up

A gout attack usually comes on suddenly, often at night or early morning. You may wake with intense pain, warmth, redness, and swelling in a joint — typically the big toe. The pain peaks within 12 to 24 hours and can be severe enough to make walking or wearing shoes unbearable.

Flare-ups typically last a few days to a couple of weeks without treatment. Some people have only one attack in their lifetime; others have them repeatedly. If you have multiple flare-ups a year, or if attacks last longer than a week, talk to your doctor about prevention strategies.

What to do during a flare

The first step is to rest the affected joint and elevate it above heart level if possible. explore ice wrapped in a cloth for 20 to 30 minutes at a time, several times a day. Avoid putting weight on the joint — crutches or a cane can help.

Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) like indomethacin, naproxen, or ibuprofen reduce pain and inflammation. Take them as directed on the package, with food if they upset your stomach. If NSAIDs don't work or you can't take them due to other health conditions, your doctor may prescribe colchicine, a medication that works best when taken within the first 24 hours of a flare.

Drink plenty of water — dehydration can make gout worse. Avoid alcohol and sugary drinks during a flare. If the pain is severe or you run a fever, contact your doctor; in some cases, a corticosteroid injection into the joint provides rapid relief.

Lowering uric acid to prevent future attacks

Once a flare settles, focus on keeping uric acid levels low. The most direct way is through diet. Cut back on red meat, organ meats (liver, kidney), and shellfish, which are high in purines. Limit sugary drinks and alcohol, especially beer, which raises uric acid more than wine or spirits. Stay well hydrated — drinking water helps your kidneys flush uric acid.

Losing weight, if you are overweight, also lowers uric acid levels. Even a 5 to 10 percent reduction in body weight can make a difference. Regular physical activity supports both weight loss and overall joint health.

Some foods are safe to eat freely: low-fat dairy products, eggs, nuts, whole grains, and most vegetables actually lower gout risk. Coffee and vitamin C may also help reduce uric acid, though the effect is modest.

Medications that prevent gout attacks

If you have frequent flare-ups — typically more than two a year — your doctor may recommend a uric acid-lowering medication. Allopurinol is the most commonly prescribed; it blocks the enzyme that produces uric acid. Febuxostat works the same way and may be an option if allopurinol doesn't suit you. Probenecid helps your kidneys excrete more uric acid.

These medications work best when uric acid stays below 6 mg/dL, the level at which crystals stop forming. Your doctor will order blood tests to check your uric acid level and adjust your dose accordingly. It can take weeks or months to reach the target level, and you may have flare-ups during this time — your doctor may prescribe a low dose of colchicine or an NSAID alongside the uric acid-lowering drug to prevent them.

Once you start a uric acid-lowering medication, you typically stay on it long-term. Stopping it suddenly can trigger a flare, so work with your doctor on any changes.

Managing related health conditions

High blood pressure, kidney disease, and diabetes all increase gout risk and can make attacks worse. If you have any of these conditions, work with your doctor to keep them under control — managing blood pressure and blood sugar reduces flare frequency.

Some blood pressure medications, like diuretics, can raise uric acid. If you take a diuretic and have gout, ask your doctor whether a different medication might work for you. Never stop a blood pressure medication on your own, but do mention gout at your next appointment so your doctor can review your options.

When to see a doctor

See your doctor if you have sudden, severe joint pain and swelling, especially if it's your first attack. A blood test can measure uric acid levels, and imaging or joint fluid analysis can confirm gout. If you have recurring flare-ups, your doctor can discuss prevention strategies and prescribe medications to lower uric acid long-term.

Seek when ready care if you develop a fever alongside joint pain, or if the pain is so severe you cannot bear weight or function — these can signal a different condition that needs urgent attention.

Frequently Asked Questions

Can I eat seafood if I have gout?

Some seafood is safer than others. Shellfish like shrimp, crab, and lobster are high in purines and should be limited. Fish like salmon and trout are lower in purines and can be eaten in moderation. Talk to your doctor or a dietitian about portion sizes that work for your uric acid levels.

Does drinking more water really help prevent gout?

Yes. Staying well hydrated helps your kidneys filter uric acid more efficiently. Aim for enough water that your urine is pale or clear. Avoid sugary drinks and alcohol, which can raise uric acid or trigger flare-ups.

If I take allopurinol, will I never have a gout attack again?

Allopurinol lowers uric acid and reduces flare frequency significantly, but some people still have occasional attacks, especially in the first few months of treatment. Your doctor may prescribe a preventive medication alongside allopurinol during this time. Once uric acid is stable at a low level, attacks become rare.

Is gout the same as regular arthritis?

No. Gout is caused by uric acid crystals and typically strikes suddenly in one joint. Osteoarthritis develops slowly over time from wear and tear, and rheumatoid arthritis is an autoimmune condition. Each has different causes and treatments, though some people have more than one type of arthritis.

Can I prevent gout if it runs in my family?

Genetics play a role, but lifestyle choices matter too. Even if gout runs in your family, maintaining a healthy weight, limiting purine-rich foods and alcohol, staying hydrated, and managing related conditions like high blood pressure can delay or prevent attacks.
