Gout: Causes, Symptoms, Uric Acid Levels, Treatment and Diet

Have you ever experienced sudden, severe pain in your big toe, ankle or knee, especially during the night? Does the affected joint become red, swollen, hot and extremely painful, even when touched lightly?

These symptoms may indicate Gout (Gouty Arthritis), a type of inflammatory arthritis caused by the accumulation of uric acid crystals in and around the joints.

Gout can cause repeated episodes of severe joint pain. Without proper management, it may eventually lead to joint damage, kidney stones and the formation of hard lumps under the skin.

What Is Gout?

Gout is a form of inflammatory arthritis that develops when uric acid levels remain high enough for urate crystals to form in the body.

Uric acid is produced when the body breaks down substances called purines. These substances are naturally present in the body and are also found in certain foods.

Normally, the kidneys remove uric acid through urine. However, when the body produces too much uric acid or the kidneys cannot remove enough of it, uric acid levels increase.

Over time, needle-shaped monosodium urate crystals can accumulate in joints and surrounding tissues, triggering inflammation and intense pain.

Common Symptoms of Gout

Gout attacks often begin suddenly, sometimes during the night. Common symptoms include:

• Sudden Severe Pain: Intense pain in a joint, commonly the base of the big toe.
• Swelling: The affected joint becomes visibly swollen.
• Redness: The skin around the joint may appear red or discoloured.
• Warmth: The affected area feels unusually warm.
• Extreme Tenderness: Even light touch or the weight of a bedsheet may become unbearable.
• Restricted Movement: Moving the affected joint becomes difficult because of pain and swelling.

Which Joints Are Commonly Affected?

Although gout is classically associated with the big toe, it can affect several other joints.

• Big toe (most characteristic site)
• Ankle
• Knee
• Foot and midfoot
• Wrist
• Fingers
• Elbow

What Causes High Uric Acid and Gout?

Several factors can contribute to increased uric acid levels and the development of gout.

1. Reduced Kidney Excretion

The kidneys play an important role in removing uric acid. Reduced kidney function can lead to uric acid accumulation.

2. Purine-Rich Foods

Some foods contain high amounts of purines, which are broken down into uric acid. Excessive consumption of organ meats, certain seafood and red meat may increase gout risk.

3. Obesity and Excess Body Weight

Excess body weight is associated with increased uric acid levels and a higher risk of gout attacks.

4. Alcohol Consumption

Alcohol, particularly beer and spirits, can increase the risk of gout attacks.

5. Sugary Drinks

Drinks containing high amounts of fructose, including some soft drinks and sweetened beverages, may increase uric acid levels.

6. Certain Medications

Some medicines, particularly diuretics (water tablets), can increase uric acid levels. Patients should not discontinue prescribed medication without consulting their doctor.

7. Family History

Genetic factors can influence how the body produces and eliminates uric acid. Gout may run in families.

What Is a Normal Uric Acid Level?

Serum uric acid is measured through a blood test.

Laboratory reference ranges can vary. A serum urate level of 6 mg/dL or above is commonly significant when evaluating suspected gout, but the blood result alone does not establish the diagnosis.

Important: Some patients may have normal uric acid levels during an acute gout attack. If gout is strongly suspected, the test may need to be repeated after the attack settles.

How Is Gout Diagnosed?

Diagnosis involves clinical examination, medical history and appropriate investigations.

1. Serum Uric Acid Test

This blood test measures the amount of uric acid in the blood.

2. Joint Fluid Examination

A sample of fluid may be collected from the affected joint and examined under a microscope. Finding monosodium urate crystals provides strong confirmation of gout.

3. Imaging

Ultrasound, X-ray or specialised CT imaging may be recommended in selected cases to identify crystal deposits or joint damage.

Gout Attack vs Other Types of Joint Pain

Not every painful or swollen joint is caused by gout. Other conditions can produce similar symptoms.

• Gout: Sudden severe pain, commonly affecting one joint, with redness and swelling.
• Rheumatoid Arthritis: An inflammatory autoimmune condition that often affects multiple joints, commonly in a symmetrical pattern.
• Osteoarthritis: Joint pain and stiffness associated with cartilage degeneration.
• Septic Arthritis: Joint infection that may cause severe pain, swelling and fever. This is a medical emergency.

A proper clinical assessment is essential to distinguish these conditions.

Stages and Progression of Gout

1. Asymptomatic Hyperuricemia

Uric acid levels are elevated, but the person has not experienced a gout attack. Not everyone with high uric acid develops gout.

2. Acute Gout Attack

Sudden inflammation develops in a joint, causing severe pain, swelling, redness and tenderness.

3. Intercritical Gout

This is the period between gout attacks. The patient may feel completely normal, but urate crystals can remain in the tissues.

4. Chronic Tophaceous Gout

Long-standing uncontrolled gout can lead to the formation of hard deposits called tophi. These deposits may develop around fingers, toes, elbows and ears and can damage joints.

Treatment of Gout

Treatment has two important objectives: controlling acute attacks and preventing future attacks.

1. Treatment During an Acute Attack

A doctor may prescribe one of the following, depending on the patient’s medical condition:

• Non-steroidal anti-inflammatory drugs (NSAIDs).
• Colchicine.
• Short-course corticosteroids.

These medicines help reduce inflammation and pain. The choice depends on kidney function, other medical conditions and medicines being taken.

2. Long-Term Uric Acid Control

Patients with recurrent attacks, tophi or other appropriate indications may require long-term urate-lowering treatment.

Common medicines include:

• Allopurinol: Reduces uric acid production.
• Febuxostat: Also reduces uric acid production.

Treatment is generally started at a low dose and adjusted according to regular serum urate measurements.

A common treatment target is serum urate below 6 mg/dL. Some patients with severe gout may require a lower target.

Patients already taking urate-lowering medication should not stop it independently during an acute attack.

Diet for Gout: What Should You Eat and Avoid?

Dietary changes can support gout management, although diet alone is often insufficient to control established gout.

Foods to Limit or Avoid

• Organ meats such as liver and kidney.
• Excessive red meat consumption.
• Certain seafood such as sardines, anchovies and shellfish.
• Beer and spirits.
• Sugar-sweetened soft drinks.
• Excessive fruit juices and fructose-rich beverages.

Foods to Include

• Low-fat milk and yoghurt.
• Vegetables and whole fruits.
• Whole grains.
• Eggs.
• Appropriate portions of lean protein.
• Plenty of water, unless fluid restriction has been advised.

Are all pulses and vegetables harmful in gout?

No. Plant-based purine-containing foods, including many vegetables and pulses, do not need to be automatically eliminated. A balanced diet is preferable to unnecessarily restrictive eating.

Can Gout Be Prevented?

Several lifestyle measures can help reduce the frequency of gout attacks.

• Maintain a healthy body weight.
• Drink adequate water.
• Limit alcohol consumption.
• Reduce sugary beverages.
• Follow a balanced dietary pattern.
• Manage diabetes, blood pressure and kidney-related conditions.
• Take prescribed uric acid-lowering medication regularly.
• Attend follow-up appointments and monitor serum urate levels.

When Should You Consult a Doctor?

Seek medical assessment if you experience:

• Your first episode of sudden joint pain and swelling.
• Repeated attacks of severe joint pain.
• Persistent swelling or restricted joint movement.
• Hard lumps around joints or under the skin.
• Symptoms despite taking prescribed treatment.

Medical Emergency: A hot, swollen and painful joint accompanied by fever, chills or feeling severely unwell may indicate septic arthritis. Seek urgent medical attention. Do not assume that it is simply gout.

Frequently Asked Questions About Gout

1. Is gout caused only by eating non-vegetarian food?

No. Gout is a metabolic condition influenced by genetics, kidney function, body weight, medications and other factors. Diet is only one contributing factor.

2. Does high uric acid always mean gout?

No. Many people have elevated uric acid without experiencing gout. Diagnosis requires clinical assessment.

3. Can gout affect the knee?

Yes. Gout can affect the knee, ankle, wrist, fingers and other joints, not just the big toe.

4. Is gout completely curable?

Gout can usually be controlled effectively. Long-term urate-lowering treatment can dissolve existing urate deposits over time and prevent further attacks in many patients.

5. Can gout damage the kidneys?

Gout is associated with kidney disease and can coexist with kidney stones. Kidney function should be assessed as part of long-term management.

6. Should I stop eating dal if I have gout?

Not necessarily. Pulses and legumes can generally be included in a balanced diet. Avoid unnecessary dietary restrictions.

Final Thoughts

Gout is more than just an increase in uric acid. It is an inflammatory joint condition caused by the deposition of urate crystals.

Ignoring repeated attacks may lead to chronic joint inflammation, tophi and permanent joint damage.

The combination of appropriate medical treatment, uric acid monitoring, healthy dietary habits and long-term follow-up can help patients control gout and maintain a better quality of life.

Do not treat a laboratory report alone. Understand the symptoms, identify the underlying problem and seek appropriate medical guidance.
