What should you know about a purine diet and gout?

Purines are natural compounds in many foods and are also made by the body. Their breakdown produces uric acid. Gout occurs when urate crystals trigger inflammation in a joint; a purine-heavy pattern, alcohol, dehydration, and other factors may contribute for some people. A flare can cause sudden joint pain, swelling, warmth, and tenderness. The condition presents with these symptoms, but a painful or swollen joint can have other causes. [Gout](/conditions/gout/) needs clinical assessment when the diagnosis is uncertain.

Keep meals regular and drink fluids unless a clinician has given you a fluid restriction. Reduce organ meats, large portions of red meat, some seafood, and alcohol if these appear to trigger symptoms. Choose varied meals with vegetables, grains, and suitable protein sources rather than following a highly restrictive plan. Gradual weight management may help when [Obesity](/conditions/obesity/) is part of the wider health picture. Do not stop gout medicine because diet changes seem helpful. If you have [Chronic Kidney Disease](/conditions/chronic-kidney-disease/), ask for personalised dietary advice.

Seek prompt assessment for a first severe attack, a hot swollen joint with fever, or symptoms that are rapidly worsening. Urgent care is needed if you feel very unwell or cannot safely move the limb. During an established flare, contact your clinician if the treatment plan is not controlling symptoms. Sudden [Joint Swelling](/symptoms/joint-swelling/) or [Ankle Swelling](/symptoms/ankle-swelling/) should not be self-diagnosed as gout.

Do my symptoms fit gout, and is joint testing needed? Which foods or drinks should I change first? How much fluid is suitable for me? Does kidney function affect my plan? Should I continue preventive medicine during a flare?
