Introduction
Gout is one of the oldest and most well-documented forms of inflammatory arthritis, yet it remains widely misunderstood. Characterized by sudden, severe attacks of pain, swelling, and redness — most commonly in the big toe — gout can be debilitating when left unmanaged. The good news: gout is one of the most treatable forms of arthritis, and with the right medical care and lifestyle adjustments, most patients can achieve full control of the disease.
For international patients and expatriates living in Shanghai, gout presents particular challenges. Rich Chinese cuisine, frequent business dining, alcohol consumption, and limited access to familiar healthcare providers can all contribute to flares. This guide covers everything you need to know about gout — from causes and diagnosis to treatment and long-term management — in the context of living in Shanghai.
What Is Gout?
Gout is a form of inflammatory arthritis caused by the accumulation of uric acid crystals (monosodium urate) in the joints. When uric acid levels in the blood become too high (a condition called hyperuricemia), crystals can form and deposit in joint spaces, triggering an intense inflammatory response.
Uric acid is a natural byproduct of the breakdown of purines — compounds found in many foods and produced naturally by the body. Normally, uric acid dissolves in the blood, passes through the kidneys, and is excreted in urine. When the body produces too much uric acid or the kidneys excrete too little, levels build up and gout can develop.
Stages of Gout
- Asymptomatic Hyperuricemia: Elevated uric acid levels with no symptoms. Not all people with hyperuricemia develop gout, but the risk increases with higher levels and duration.
- Acute Gout Flare: Sudden onset of intense joint pain, swelling, warmth, and redness. Attacks often begin at night and peak within 12–24 hours. The big toe (podagra) is the classic site, but ankles, knees, wrists, and elbows can also be affected.
- Intercritical Gout: The period between flares. Patients are symptom-free but uric acid crystals remain in the joints. Without treatment, flares become more frequent and severe over time.
- Chronic Tophaceous Gout: Long-standing, uncontrolled gout leads to the formation of tophi — deposits of uric acid crystals under the skin — and can cause permanent joint damage and deformity.
Symptoms
A gout attack typically presents with:
- Sudden, severe joint pain — often described as the worst pain imaginable
- Swelling, redness, and warmth over the affected joint
- Extreme tenderness — even the weight of a bedsheet can be unbearable
- Limited range of motion in the affected joint
- Peeling and itching of the skin over the joint as the attack resolves
Attacks typically last 3–10 days and resolve spontaneously, even without treatment. However, without uric acid-lowering therapy, attacks will recur and worsen over time.
Causes & Risk Factors
Dietary Triggers
- High-purine foods: Red meat, organ meats (liver, kidney), shellfish (shrimp, crab, lobster), and certain fish (anchovies, sardines, mackerel)
- Alcohol: Beer and spirits are particularly problematic; wine in moderation has less impact
- Fructose-sweetened beverages: Soft drinks and fruit juices sweetened with high-fructose corn syrup
- Shanghai dining context: Business banquets, hotpot, seafood, and frequent alcohol consumption are common triggers for expats in Shanghai
Medical & Lifestyle Risk Factors
- Obesity
- Hypertension (high blood pressure)
- Chronic kidney disease (reduced uric acid excretion)
- Diabetes and metabolic syndrome
- Certain medications: diuretics (thiazides), low-dose aspirin, cyclosporine
- Family history of gout
- Male sex (men are affected 3–4 times more often than women; postmenopausal women have increased risk)
- Recent surgery, trauma, or illness (can trigger a flare)
Diagnosis
Gout is diagnosed through a combination of clinical assessment and laboratory testing:
- Joint fluid analysis (arthrocentesis): The gold standard — a needle is used to withdraw fluid from the affected joint, which is examined under a microscope for uric acid crystals. This definitively confirms gout.
- Blood uric acid level: Elevated serum uric acid (>420 μmol/L or >7 mg/dL) supports the diagnosis, though levels can be normal during an acute attack.
- X-ray: May show joint damage in chronic gout; not useful for early diagnosis.
- Ultrasound or dual-energy CT (DECT): Advanced imaging that can detect uric acid crystal deposits; increasingly available at top Shanghai hospitals.
- Blood tests: Kidney function, full blood count, and metabolic panel to assess comorbidities and guide treatment.
It is important to distinguish gout from other forms of arthritis such as pseudogout (calcium pyrophosphate crystals), septic arthritis (joint infection), and rheumatoid arthritis, as treatments differ significantly.
Treatment
Treating an Acute Gout Flare
The goal is to reduce inflammation and pain as quickly as possible. Options include:
- NSAIDs (non-steroidal anti-inflammatory drugs): Indomethacin, naproxen, or celecoxib are first-line treatments. Most effective when started within the first 24 hours of a flare.
- Colchicine: Highly effective for acute gout, particularly when started early. Low-dose colchicine (1.2 mg followed by 0.6 mg one hour later) is the preferred regimen. Available in China.
- Corticosteroids: Oral prednisone or intra-articular (joint) steroid injection for patients who cannot tolerate NSAIDs or colchicine (e.g., those with kidney disease).
Long-Term Uric Acid-Lowering Therapy (ULT)
ULT is the cornerstone of gout management and should be considered for patients with recurrent flares (≥2 per year), tophi, chronic kidney disease, or uric acid kidney stones. The target serum uric acid level is <360 μmol/L (<6 mg/dL), or <300 μmol/L for patients with tophi.
- Allopurinol: The most widely used ULT worldwide. Reduces uric acid production. Start at a low dose and titrate up. Available and affordable in China.
- Febuxostat: An alternative xanthine oxidase inhibitor, particularly useful for patients who cannot tolerate allopurinol. Widely available in China.
- Benzbromarone: A uricosuric agent that increases uric acid excretion via the kidneys. Commonly used in China and Asia; less available in Western countries.
- Probenecid: Another uricosuric option, used less frequently.
Important: ULT should not be started during an acute flare, as it can prolong or worsen the attack. Anti-inflammatory prophylaxis (low-dose colchicine or NSAIDs) is recommended for the first 3–6 months of ULT initiation to prevent flares triggered by falling uric acid levels.
Diet & Lifestyle Management
Dietary modification alone is rarely sufficient to normalize uric acid levels, but it plays an important supporting role alongside medication:
Foods to Limit or Avoid
- Organ meats (liver, kidney, sweetbreads)
- High-purine seafood (anchovies, sardines, mussels, scallops, shrimp, lobster)
- Red meat in large quantities
- Beer and spirits
- Fructose-sweetened soft drinks and juices
Foods That May Help
- Low-fat dairy products (associated with lower uric acid levels)
- Cherries and cherry juice (shown to reduce gout flare frequency)
- Vegetables (even high-purine vegetables like asparagus and spinach do not significantly raise uric acid)
- Coffee (moderate consumption associated with lower uric acid)
- Adequate hydration: aim for 2–3 liters of water daily to promote uric acid excretion
Lifestyle Modifications
- Achieve and maintain a healthy weight (crash dieting can trigger flares)
- Exercise regularly with low-impact activities (swimming, cycling, walking)
- Limit alcohol, particularly beer
- Review medications with your doctor — diuretics and low-dose aspirin can raise uric acid levels
Gout & Comorbidities
Gout rarely occurs in isolation. It is strongly associated with metabolic syndrome and cardiovascular disease. Patients with gout should be screened and managed for:
- Hypertension
- Type 2 diabetes
- Dyslipidemia (high cholesterol/triglycerides)
- Chronic kidney disease
- Cardiovascular disease
Treating gout effectively also reduces cardiovascular risk. A rheumatologist working in coordination with an internist or cardiologist provides the most comprehensive care.
Managing Gout in Shanghai
Practical considerations for international patients:
- Medications: Allopurinol, febuxostat, benzbromarone, colchicine, and NSAIDs are all readily available at Chinese pharmacies and hospitals. Prescriptions are required for most medications.
- Specialist care: Rheumatology departments at Shanghai's top hospitals (Ruijin Hospital, Zhongshan Hospital, Renji Hospital) have extensive experience managing gout and hyperuricemia.
- Dietary navigation: Navigating Shanghai's food culture with gout requires awareness. Business banquets, hotpot restaurants, and seafood-heavy menus are common triggers. Communicating dietary restrictions in Chinese can be challenging — CMCS can provide guidance and translation support.
- Regular monitoring: Serum uric acid should be checked every 2–4 weeks when initiating or adjusting ULT, then every 6 months once stable. Kidney function should be monitored regularly.

Frequently Asked Questions
Is gout caused only by diet?
No. While diet plays a role, gout is primarily a metabolic condition. Genetics, kidney function, and certain medications are equally or more important. Most patients require medication in addition to dietary changes.
Can gout be cured?
Gout cannot be cured, but it can be fully controlled. With appropriate uric acid-lowering therapy and lifestyle management, most patients can become completely flare-free.
Should I take uric acid-lowering medication every day, even when I have no symptoms?
Yes. ULT must be taken consistently to keep uric acid levels below the target threshold. Stopping medication allows uric acid to rise again and flares to return.
Can I drink alcohol if I have gout?
Alcohol — particularly beer and spirits — significantly raises uric acid levels and should be minimized or avoided. Moderate wine consumption has less impact but should still be limited.
Is gout covered by international health insurance?
Yes, gout diagnosis and treatment are typically covered by international health insurance plans. CMCS can assist with insurance verification and claims coordination.
What should I do during a gout attack in Shanghai?
Rest the affected joint, apply ice, stay well hydrated, and seek medical attention promptly. A doctor can prescribe NSAIDs, colchicine, or steroids to shorten the attack. Contact CMCS if you need help accessing care quickly.
