Gout

Definition

Inflammatory arthritis caused by monosodium urate crystal deposition in joints and surrounding tissues, typically affecting the great toe and triggered by hyperuricemia.

How it works

Gout develops when serum uric acid levels exceed saturation point, typically above 6.8 mg/dL, promoting crystal formation in joints and tissues. Hyperuricemia results from excessive purine intake from red meat, organ meats, certain seafood, and alcohol, combined with reduced uric acid excretion due to dehydration, renal disease, or genetic factors. Acute gout attacks cause severe pain, swelling, and erythema lasting days to weeks. Chronic gout leads to tophi formation, joint damage, and urate nephropathy. Dietary modification reducing purine and refined carbohydrate intake while increasing low-fat dairy, cherries, and hydration effectively lowers uric acid levels and reduces attack frequency.

Role

Indicates excessive uric acid accumulation requiring dietary purine restriction and hydration to prevent acute attacks and joint damage.

Examples

• High red meat and organ meat consumption
• Excessive beer and alcohol intake
• High fructose beverage consumption
• Dehydration and obesity

Recommendations

Limit purine-rich foods including red meat, organ meats, anchovies, and shellfish to modest portions. Increase low-fat dairy intake and consume cherries regularly, which lower uric acid. Maintain hydration with 2-3 liters of water daily and avoid sugary drinks, beer, and excessive alcohol.

Key takeaway

Gout management requires sustained purine dietary restriction, adequate hydration, low-fat dairy intake, and weight loss to prevent recurrent acute attacks.
