Gout is a form of inflammatory arthritis caused by a buildup of uric acid crystals in your joints. It strikes suddenly, often in the middle of the night, producing intense pain that peaks within 4 to 12 hours. The big toe is the most common target, but gout can affect ankles, knees, wrists, fingers, and elbows. About 4% of American adults have gout, and it’s significantly more common in men than women.
What Causes Gout
Your body produces uric acid when it breaks down substances called purines, which occur naturally in your cells and in many foods. Normally, uric acid dissolves in your blood, passes through your kidneys, and leaves your body in urine. When your body produces too much uric acid or your kidneys don’t filter enough of it out, uric acid accumulates and forms sharp, needle-like crystals in and around a joint. Those crystals trigger the intense inflammation and pain of a gout attack.
Not everyone with high uric acid levels develops gout. But several factors raise your risk considerably. Being overweight is one of the strongest, because extra body weight increases uric acid production and makes it harder for your kidneys to clear it. A family history of gout, kidney disease, and certain medications (particularly diuretics used for blood pressure) also increase your likelihood.
How a Gout Attack Feels
Gout flares almost always come on suddenly. The affected joint becomes hot, swollen, red, and so tender that even the weight of a bedsheet can feel intolerable. Most people describe the pain as throbbing or crushing, and it often wakes them from sleep.
The worst pain typically hits within the first 4 to 12 hours. After that initial spike, lingering joint discomfort can last anywhere from a few days to a few weeks. Early attacks usually affect a single joint, most often the base of the big toe, though the midfoot, ankle, and knee are also common first targets. As gout progresses over time, flares may involve multiple joints and become more frequent.
Between attacks, you may feel completely normal. These symptom-free gaps can last months or even years early on, which sometimes leads people to assume the problem has resolved on its own. It hasn’t. Without management, the intervals between flares tend to shorten.
Foods and Drinks That Trigger Flares
Certain foods are high in purines and directly raise uric acid levels. Organ meats like liver, kidney, and sweetbreads are among the worst offenders. Red meat (beef, lamb, pork) and specific types of seafood, including anchovies, sardines, shellfish, and codfish, also contribute significantly.
Alcohol is a major trigger. Beer is the strongest culprit because it contains purines of its own, but distilled liquors also increase risk. Both are linked to more frequent attacks. If you’re in the middle of a flare, avoiding alcohol entirely is wise, and limiting it between flares helps prevent recurrence.
Sugar plays a bigger role than many people realize. Foods and drinks sweetened with high-fructose corn syrup, including sodas, certain cereals, baked goods, and even some salad dressings, can raise uric acid levels. Cutting back on added sugar of all types reduces gout risk. Saturated fats from red meat, poultry skin, and full-fat dairy are also worth limiting, both for gout and overall metabolic health.
What Happens If Gout Goes Untreated
Left unmanaged, gout progresses through stages that become increasingly difficult to reverse. What starts as occasional flares in a single joint can evolve into chronic gout affecting multiple joints in both the upper and lower body. At that stage, pain becomes constant rather than episodic, and permanent joint damage sets in. Some people develop difficulty walking or lose the ability to use affected joints normally.
One of the more visible complications is the formation of tophi: hard lumps of uric acid that develop under the skin, typically on the joints, fingers, elbows, or the upper ear. Tophi can be painful and disfiguring, and they signal that uric acid levels have been elevated for a long time.
Gout also threatens your kidneys. Uric acid crystals can form kidney stones, which are painful on their own but can also block the kidneys from filtering waste, cause infections, and scar kidney tissue with their sharp edges. Over time, these problems can lead to chronic kidney disease or even kidney failure. This connection between gout and kidney damage is one of the strongest reasons to take the condition seriously rather than just treating individual flares.
How Gout Is Treated
Treatment works on two fronts: stopping the pain of an active flare and lowering uric acid levels long-term to prevent future attacks.
For active flares, treatment is most effective when started within hours of symptom onset. Your doctor will typically prescribe anti-inflammatory medications or corticosteroids to bring down the swelling and pain. If only one or two joints are involved, a corticosteroid injection directly into the joint is sometimes an option. Most flares resolve within a week or two with proper treatment, though tapering off medication too quickly can cause a rebound flare.
Long-term management focuses on keeping uric acid levels below 6 mg/dL, the threshold where crystals stop forming and existing deposits gradually dissolve. Medications that lower uric acid production are the cornerstone of this approach. Your doctor may start at a low dose and adjust upward over several weeks based on blood tests. This maintenance therapy is typically ongoing, because uric acid levels climb back up once the medication stops.
Lifestyle Changes That Help
Medication handles the chemistry, but lifestyle adjustments meaningfully reduce how often flares occur. Losing weight, if you’re carrying extra, is one of the most impactful changes you can make. It lowers uric acid production and reduces the metabolic stress that drives gout.
On the dietary side, the biggest gains come from reducing the highest-purine foods (organ meats, certain seafood), cutting back on alcohol (especially beer), and limiting sugar-sweetened foods and drinks. You don’t need to eliminate purines entirely, but shifting toward lower-purine protein sources like eggs, low-fat dairy, and most vegetables makes a real difference. Staying well-hydrated also helps your kidneys clear uric acid more efficiently.
These changes work best alongside medication rather than as a substitute. Diet alone rarely brings uric acid levels low enough to prevent flares in people with established gout, but it can reduce the medication dose needed and lower the frequency of attacks between adjustments.
