Gout is a form of inflammatory arthritis caused by a buildup of uric acid in the blood, which forms sharp, needle-like crystals inside your joints. It affects roughly 3.9% of adults in the United States and is one of the most painful joint conditions. Flares come on suddenly, often in the middle of the night, and typically resolve within one to two weeks.
How Uric Acid Crystals Cause a Flare
Your body produces uric acid when it breaks down purines, natural compounds found in your cells and in certain foods. Normally, uric acid dissolves in your blood, passes through your kidneys, and leaves your body in urine. When your blood uric acid level rises above about 7 mg/dL, it exceeds the limit of what can stay dissolved. The excess uric acid begins forming tiny monosodium urate crystals that deposit in and around joints.
These crystals can sit in a joint for years without causing symptoms. But when they shift or accumulate enough to trigger your immune system, your body launches an intense inflammatory response. White blood cells swarm the crystals, releasing signaling molecules that cause rapid swelling, heat, redness, and severe pain. This is what makes a gout flare feel so sudden and extreme compared to other types of arthritis.
What a Gout Attack Feels Like
Gout most commonly strikes the base of the big toe, but it can affect the ankles, knees, elbows, wrists, and fingers. A flare often begins at night with a sharp, throbbing pain that intensifies quickly. Within hours, the affected joint becomes swollen, warm to the touch, and so tender that even the weight of a bedsheet can feel unbearable.
The worst pain usually hits within the first 12 to 24 hours. After that, the discomfort gradually eases over the next one to two weeks. Between flares, most people have no symptoms at all, which can make it tempting to ignore the condition. But without treatment, flares tend to come back more frequently and last longer.
Who Gets Gout and Why
Gout is nearly twice as common in men as in women, and the risk increases with age. Among adults 65 and older, rates climb significantly for both sexes. Several overlapping factors raise your likelihood of developing the condition:
- High blood pressure: Nearly three-quarters of people with gout also have hypertension, and the relationship runs both ways.
- Obesity and metabolic syndrome: Excess body weight increases uric acid production and makes it harder for your kidneys to clear it.
- Chronic kidney disease: Reduced kidney function slows uric acid excretion, allowing levels to climb.
- Certain medications: Diuretics (water pills) are a well-known trigger. Combining a loop diuretic with a thiazide diuretic can raise gout risk by as much as five times. Low-dose aspirin, some blood pressure medications, and certain immunosuppressive drugs also reduce the kidneys’ ability to clear uric acid.
- Genetics: Family history plays a meaningful role in how efficiently your body processes uric acid.
Foods and Drinks That Raise Uric Acid
Purines in food break down into uric acid, so what you eat directly influences your blood levels. The highest-risk foods include organ meats like liver, kidney, and sweetbreads, which are packed with purines. Red meat (beef, lamb, pork) should be limited in portion size. Among seafood, anchovies, sardines, shellfish, and cod are the biggest contributors.
Alcohol is a significant trigger. Beer is the worst offender because it contains purines of its own on top of impairing your kidneys’ ability to excrete uric acid. Distilled liquors also increase risk, though to a lesser degree. During an active flare, avoiding alcohol entirely helps your body recover faster.
How Gout Is Diagnosed
The gold standard for diagnosis is finding urate crystals in fluid drawn from the affected joint. If crystals are present, no further testing is needed. When joint aspiration isn’t practical, doctors use a combination of clinical features, blood tests, and imaging. A serum uric acid level above 7 mg/dL supports the diagnosis, though some people have normal levels during an active flare because the uric acid has already deposited into the joint.
Imaging can help confirm the diagnosis in less obvious cases. Ultrasound can reveal a characteristic “double contour” sign on the surface of cartilage, and dual-energy CT scans can detect urate deposits even before they become visible lumps. Standard X-rays are more useful for spotting damage from longstanding gout, such as joint erosion.
Treating Active Flares
Treatment for a gout attack focuses on stopping the inflammation as quickly as possible. Over-the-counter anti-inflammatory drugs like ibuprofen or naproxen are often the first step. For more severe flares, doctors may prescribe stronger anti-inflammatory medications or corticosteroids to bring the swelling down rapidly. A prescription anti-inflammatory called colchicine is particularly effective for gout pain when started early in a flare.
Most people notice significant improvement within a few days of starting treatment, though some residual soreness can linger for a week or more. Resting the joint, applying ice, and keeping it elevated all help during this period.
Preventing Future Attacks
If you have frequent flares, visible crystal deposits, kidney stones, or joint damage, your doctor will likely recommend long-term medication to lower your uric acid levels. These medications work in two ways: some reduce the amount of uric acid your body produces, while others help your kidneys excrete more of it. The treatment target is typically a blood uric acid level at or below 6 mg/dL, which sits comfortably below the crystallization threshold of 7 mg/dL.
Lowering uric acid is a gradual process. In the first few months of treatment, flares can actually increase temporarily as existing crystals begin to dissolve and shift. This is a normal part of the process, not a sign that the medication isn’t working. Over time, as the crystal burden decreases, flares become less frequent and eventually stop for most people who stick with treatment.
What Happens if Gout Goes Untreated
Left unmanaged, gout progresses. Urate crystals continue accumulating and can form visible, chalky lumps called tophi under the skin, typically around the fingers, elbows, or ears. Tophi are painless at first but can eventually erode bone and cartilage, causing permanent joint damage.
The effects extend beyond the joints. Excess uric acid increases the risk of kidney stones, and the chronic inflammation associated with tophi accelerates kidney function decline. In one study, patients with tophi lost kidney function at roughly seven times the rate of gout patients without tophi. This makes early, consistent treatment important not just for pain relief but for protecting your kidneys and joints long-term.
