Yes. Gout is a common type of inflammatory arthritis. It starts when uric acid builds up in the blood and forms crystals in a joint. The immune system treats those crystals as a threat and releases a strong inflammation signal called IL-1β, which sets off the pain and swelling of a flare.
What is gout?
A gout flare usually hits one joint at a time, most often in the leg or foot. It comes on fast as an inflammatory arthritis that settles down on its own. The joint swells, hurts and gets hard to move.
Behind the flare sits a chemistry problem. Uric acid is a normal waste product in your blood. When the level climbs too high (doctors call this hyperuricemia), it can form needle-like crystals in and around joints. High uric acid is the most important risk factor for gout.
Your kidneys and gut set much of that level. Proteins in both places move urate in and out of the body, so gout is not only about food.
Is gout inflammatory or noninflammatory?
Inflammatory. A 2025 systematic review calls gout "a common type of inflammatory arthritis" caused by urate crystals in the joints. The 2021 Lancet review of the disease says the same thing in more detail.

Here is how a flare starts. Immune cells in the joint find the crystals and switch on a sensor called the NLRP3 inflammasome. Think of it as a smoke detector inside the cell. Once it trips, it releases IL-1β, a signal protein that drives inflammation. That release plays a major role in starting the flare. Other immune cells, called neutrophils, later clump together and help the flare wind down.
The best proof that IL-1β matters comes from drugs that block it. A 2023 review gathered 14 studies, 10 of them randomized trials, with 4,367 people who had gout. In those trials, two of the IL-1β blockers eased pain better than a standard treatment and cut how often flares came back.
Does gout cause inflammation in the body?
A flare is a local fire, but gout is a long-term disease. The flares come and go. The crystals and the high uric acid behind them stay. That is why guidelines plan gout care for the long term, not just flare by flare.
The inflammation may also reach past the joint. A 2022 study used English health records to look at people with gout who had a heart attack or stroke. Among 1,421 people who had both a flare and one of these events, the rate of heart attacks and strokes was close to double in the 60 days after a flare. The risk was smaller by days 121 to 180. This was an observational study, so it shows a link in time, not proof that the flare caused the heart attack.
Which habits are linked to fewer gout flares?
Nineteen cohort and cross-sectional studies were pooled in a 2018 meta-analysis, which combines the results of many studies. Alcohol was linked to about two and a half times the odds of gout. Fructose, a sugar found in many sweet drinks and foods, was linked to about twice the odds. Red meat and seafood carried a smaller added risk. Dairy, soy and coffee were linked to lower odds. A 2024 meta-analysis of observational studies found much the same pattern, and it linked vegetables to lower uric acid.
Body weight shows up again and again. A 2022 analysis of US data found that each 5-point rise in body mass index (BMI) went with a 1.48-fold higher risk of gout. Excess weight, high blood pressure and alcohol together accounted for about 65% of new gout cases.
What about people who already have gout? A 2025 review of 8 studies with 47,879 participants looked at flares directly. Fish rich in healthy polyunsaturated fats, regular exercise and more vegetables were linked to fewer flares. Eating lots of purines (especially from animal foods), heavy drinking and obesity were linked to more. Purines are food compounds that turn into uric acid.
There is a catch. Some studies saw diet changes lower uric acid, and others did not. Habits help, but for many people they are not enough on their own. Both major guidelines build long-term care around keeping uric acid below 6 mg/dl, because steady lowering dissolves the crystals and, over time, prevents flares.

Tick what you'll try this week. Your picks stay on this device.
you have a hot, swollen joint for the first time, especially with a fever (an infected joint needs ruling out fast); you have two or more flares a year, kidney disease, kidney stones or lumps under the skin near a joint; or you have heart disease and just had a flare.

The bottom line
Gout starts as a chemistry problem and turns into an immune one. Uric acid rises, crystals form, a sensor in your immune cells trips, and IL-1β sets the joint alight. Every link in that chain is well studied. That is why we grade the main question Strong. The habits tied to fewer flares all point at the same target: less uric acid and fewer crystals. That is a chain you can start loosening this week, one drink and one meal at a time.
Common questions
Does gout cause inflammation in the body?
The flare itself happens in the joint. But gout is a chronic disease, and the crystals stay between flares. A 2022 study of English health records found heart attacks and strokes were more common in the months after a gout flare, most of all in the first 60 days. That study shows a link, not cause, but it is a good reason to take flares seriously.
Is gout inflammatory or noninflammatory?
Gout is an inflammatory arthritis. Urate crystals in the joint switch on the NLRP3 inflammasome, an immune sensor that releases the inflammation signal IL-1β. That release plays a major role in starting a flare, which brings pain, swelling and stiffness. Drugs that block IL-1β eased flare pain in randomized trials.
Why does gout cause inflammation in the foot?
Gout most often shows up in the joints of the leg and foot, usually one joint at a time. Urate crystals build up in and around joints when uric acid stays high. Once immune cells find the crystals, they release IL-1β, and the joint swells and hurts. The flare tends to settle on its own, but the crystals remain.
Can diet alone control gout?
For some people it helps, but it is often not enough. A 2025 review found some diet changes lowered uric acid while others did not. Guidelines build long-term care around keeping uric acid below a set target, which dissolves the crystals over time and prevents flares. Diet and exercise support that plan.
