What is Gout?
Gout is the most common form of inflammatory arthritis, caused by the buildup of uric acid crystals in the joints. When uric acid levels in the blood become too high, sharp crystals can form and deposit in joint tissue, triggering sudden episodes of severe pain, swelling, and redness.
Gout affects approximately 9.2 million American adults, and its prevalence has been increasing over recent decades. While gout can strike at any age, it is most common in men over 40 and in women after menopause. According to research published in The Lancet Rheumatology, the global burden of gout is projected to rise significantly by 2050, particularly among older adults in high-income countries.
Unlike osteoarthritis, which develops gradually from cartilage wear, gout attacks can come on suddenly and with extreme intensity. The good news is that gout is one of the most treatable forms of arthritis when managed properly.
Understanding Uric Acid and Gout
Uric acid is a natural waste product created when your body breaks down substances called purines. Purines are found in your body’s cells and in certain foods. Normally, uric acid dissolves in the blood, passes through the kidneys, and leaves the body in urine.
Gout develops when one of two things happens:
- Your body produces too much uric acid
- Your kidneys do not remove enough uric acid
When blood uric acid levels exceed approximately 6.8 mg/dL, crystals of monosodium urate can form in joints and surrounding tissue. These needle-shaped crystals trigger an intense inflammatory response, causing the severe pain characteristic of a gout attack.
Acute Gout vs. Chronic Gout
Acute Gout Attacks
Acute gout is characterized by sudden, severe flares:
- Rapid onset: Pain often begins at night and reaches maximum intensity within 12 to 24 hours
- Single joint involvement: Usually one joint at a time, most commonly the big toe (called podagra)
- Extreme pain: Many patients describe it as the worst pain they have ever experienced
- Self-limiting: Without treatment, attacks typically resolve within 7 to 14 days
- Recurrence: Most patients will have another attack within 2 years if untreated
Chronic Gout
Without proper management, gout can progress to a chronic condition:
- Frequent attacks: Episodes become more common and last longer
- Multiple joints: More joints become affected over time
- Tophi formation: Hard, chalky deposits of uric acid crystals form under the skin, often near joints, ears, or fingers
- Joint damage: Chronic inflammation can cause permanent joint erosion and damage
- Kidney problems: Uric acid crystals can form kidney stones
Symptoms to Watch For
During an Acute Attack
- Sudden, severe joint pain that often wakes you at night
- Intense swelling that may make the joint appear twice its normal size
- Red or purple skin over the joint
- Heat radiating from the affected area
- Extreme tenderness where even the weight of a bedsheet causes pain
- Fever in some cases
Common Joints Affected
- Big toe (most common, affected in about 50% of first attacks)
- Ankles and feet
- Knees
- Wrists and fingers
- Elbows
Warning Signs of Chronic Gout
- Attacks happening more than twice per year
- Visible lumps (tophi) near joints
- Joint stiffness between attacks
- Reduced range of motion
Causes and Risk Factors
Dietary Factors
- High-purine foods: Red meat, organ meats (liver, kidney), game meats
- Seafood: Shellfish, anchovies, sardines, mackerel
- Alcohol: Beer and spirits increase uric acid levels; moderate wine intake appears less risky
- Sugary drinks: Fructose-sweetened beverages raise uric acid
- Dehydration: Insufficient water intake impairs uric acid excretion
Medical Risk Factors
- Kidney disease: Reduced ability to excrete uric acid
- High blood pressure: Strongly associated with gout
- Diabetes and metabolic syndrome: Increase uric acid levels
- Heart disease: Shares many risk factors with gout
- Medications: Diuretics (water pills), low-dose aspirin, and some immunosuppressants can raise uric acid
Who Is Most at Risk?
- Men are 3 to 4 times more likely to develop gout
- Risk increases with age (especially after 40 in men, after menopause in women)
- Family history of gout increases your risk
- Obesity significantly raises the likelihood of developing gout
Diagnosis
Clinical Evaluation
- Review of symptoms, diet, and medical history
- Physical examination of affected joints
- Assessment of attack pattern and frequency
Laboratory Tests
- Serum uric acid level: Levels above 6.8 mg/dL support the diagnosis, though some patients have normal levels during an acute attack
- Joint fluid analysis: The gold standard. A doctor uses a needle to draw fluid from the joint and examines it under a microscope for urate crystals
- Blood tests: Complete blood count and inflammatory markers (ESR, CRP)
- Kidney function tests: To assess uric acid excretion
Imaging
- X-rays: May show joint damage in chronic gout
- Ultrasound: Can detect crystal deposits and the “double contour sign” on cartilage
- Dual-energy CT scan: Highly accurate for identifying urate crystal deposits
Treatment Options
Treating Acute Attacks
The goal during an acute attack is rapid pain relief:
- NSAIDs: Indomethacin, naproxen, or ibuprofen at prescription doses
- Colchicine: Most effective when started within 12 hours of attack onset
- Corticosteroids: Oral prednisone or a corticosteroid injection directly into the joint, especially helpful when NSAIDs or colchicine cannot be used
- Ice and rest: Apply ice for 20 minutes at a time and keep weight off the joint
Long-Term Urate-Lowering Therapy
For patients with recurrent attacks, lowering uric acid levels prevents future flares:
- Allopurinol: The most commonly prescribed urate-lowering medication, taken daily
- Febuxostat (Uloric): An alternative for patients who cannot tolerate allopurinol
- Probenecid: Helps the kidneys excrete more uric acid
The target uric acid level is below 6.0 mg/dL. When starting urate-lowering therapy, your doctor may also prescribe colchicine or a low-dose NSAID for several months to prevent flares during the adjustment period.
Lifestyle Modifications
- Dietary changes: Limit high-purine foods, reduce alcohol intake, avoid sugary beverages
- Hydration: Drink plenty of water to help flush uric acid
- Weight management: Gradual weight loss reduces uric acid levels (avoid crash dieting, which can trigger attacks)
- Exercise: Low-impact activity helps maintain joint function and manage weight
- Cherry intake: Some research suggests tart cherry juice or extract may modestly lower uric acid
Physical Therapy
After an acute attack resolves, physical therapy can help:
- Restore range of motion in affected joints
- Strengthen surrounding muscles
- Improve balance and mobility, especially after ankle or knee attacks
- Develop a safe exercise routine
Prevention Strategies
- Take urate-lowering medications as prescribed (do not stop during symptom-free periods)
- Stay well hydrated throughout the day
- Limit red meat, shellfish, and organ meats
- Moderate alcohol consumption
- Maintain a healthy weight through gradual changes
- Monitor uric acid levels regularly with your doctor
Questions to Ask Your Healthcare Provider
- Is my joint pain caused by gout or another type of arthritis?
- Should I have a joint fluid analysis to confirm the diagnosis?
- Do I need urate-lowering therapy, and for how long?
- What dietary changes will make the biggest difference?
- Could any of my current medications be contributing to high uric acid?
- How often should I have my uric acid levels checked?
Frequently Asked Questions
Can gout cause permanent joint damage?
Yes. Untreated chronic gout can lead to permanent joint erosion, tophi formation, and loss of joint function. However, with proper treatment including urate-lowering therapy, joint damage can be prevented. Early and consistent treatment is key.
Is gout only a disease of the big toe?
No. While the big toe is the most commonly affected joint (about 50 percent of first attacks), gout can affect the ankles, knees, wrists, fingers, and elbows. As gout progresses, it may affect multiple joints simultaneously.
Can diet alone cure gout?
Diet plays an important role in managing gout, but dietary changes alone typically lower uric acid by only 1 to 2 mg/dL. Most patients with recurrent gout need medication in addition to lifestyle changes to reach target uric acid levels below 6.0 mg/dL.
Does gout affect older adults differently?
Gout in older adults may present differently. Women are more likely to develop gout after menopause. Older patients may have gout in unusual joints and are more likely to have chronic (tophaceous) gout. Kidney function decline with age can also make uric acid management more challenging. Your doctor should consider kidney function when choosing medications.
