Overview

What Is Gout?

Gout is a common form of inflammatory arthritis caused by deposits of urate crystals in and around a joint. It often affects the big toe, but it can also involve the ankles, knees, fingers, wrists, or other joints. The crystals form when uric acid builds up in the blood. Recurrent gout attacks are treatable with appropriate medical care and long-term urate control.

Symptoms

Gout Symptoms

Gout attacks are sudden episodes of intense joint inflammation that often begin at night. The big toe is a common location, although gout in the foot, ankle, knee, or another joint is also possible. Symptoms may be severe enough to make even light contact uncomfortable.

  • Severe joint pain that starts suddenly.
  • Swelling around the affected joint.
  • Red or purplish skin over the joint.
  • Warmth over the inflamed area.
  • Marked tenderness, even with light touch.
  • Reduced movement of the joint.

Causes

What Causes Gout?

Gout occurs when uric acid builds up in the blood and forms monosodium urate crystals in and around joints. This usually happens because the kidneys do not remove enough uric acid, although the body may also produce too much. The crystals can activate inflammation and cause a painful flare. These biological causes are different from factors that trigger an attack in someone who already has high uric acid levels.

  • Dehydration can make it easier for urate crystals to form or trigger symptoms.
  • An illness or sudden change in health may bring on a flare.
  • Injury or stress to a joint can trigger inflammation.
  • Alcohol, especially in larger amounts, can raise the risk of an attack.
  • Rapid dietary changes or fasting may contribute to a flare.
  • Starting or stopping certain medicines without medical guidance can affect uric acid levels.

Risk Factors

Who Is More Likely to Develop Gout?

  • Family history is a non-modifiable factor because inherited traits can affect uric acid handling.
  • Older age and male sex are associated with a higher likelihood of gout, although anyone can develop it.
  • Kidney disease can reduce uric acid removal and is a partly modifiable medical risk factor.
  • Obesity, high blood pressure, diabetes, and metabolic syndrome can increase risk and may be partly modifiable.
  • Purine-rich foods, including some meats and seafood, may contribute to risk but do not guarantee gout.
  • Sugary drinks can increase uric acid exposure and are a modifiable dietary risk factor.
  • Alcohol can raise risk, particularly when consumed frequently or in larger amounts.
  • Dehydration can make gout attacks more likely and is often modifiable.
  • Diuretics and some other medicines may raise uric acid levels, so medication decisions should be made with a clinician.

Medication safety

Review medicines safely

Do not stop, restart, or change a prescribed medicine to prevent gout without speaking with the prescribing clinician. They can weigh the medicine’s benefits, review alternatives, and monitor uric acid and kidney function when needed.

Complications

Gout Complications

  • Untreated gout may cause attacks that become more frequent or last longer.
  • Tophi are firm deposits of urate that can develop under the skin or around joints.
  • Persistent inflammation can lead to permanent joint damage and reduced movement.
  • Urate buildup can contribute to kidney stones.
  • Long-standing gout may be associated with impaired kidney function.

Diagnosis

How Gout Is Diagnosed

Diagnosis considers the pattern of the attack, the affected joint, your medical history, medicines, and examination findings. Several conditions, including a joint infection, can resemble gout. A clinician may use blood tests, joint-fluid testing, kidney-function testing, or imaging to clarify the cause and guide treatment.

  • A serum uric acid test measures the amount of uric acid in the blood.
  • Joint-fluid analysis can identify urate crystals and help distinguish gout from infection or other arthritis.
  • Kidney-function testing helps assess uric acid clearance and guide medicine choices.
  • Ultrasound or dual-energy CT may show urate deposits when the diagnosis remains uncertain.
  • Plain X-rays may help assess established disease or investigate another suspected cause of joint symptoms.

Testing limits

Blood test limits

A uric acid blood test can be normal during a gout flare, so a normal result does not by itself confirm or rule out gout. Clinicians interpret the result alongside the examination, symptom pattern, and other tests.

Treatment & Management

Gout Treatment and Management

Gout treatment focuses on relieving acute attacks, preventing future episodes, and lowering uric acid levels. During an acute attack, NSAIDs, colchicine, or corticosteroids may be used to reduce pain and inflammation. Treatment choice depends on the patient’s other medical conditions and potential medication risks.

For long-term management, urate-lowering therapy, such as allopurinol or febuxostat, may be prescribed to reduce serum uric acid levels and prevent recurrent attacks and complications. These medications are usually started at a low dose and adjusted according to uric acid levels. Anti-inflammatory prophylaxis may be used when urate-lowering therapy is initiated.

Lifestyle measures can also help. Maintaining a healthy weight, limiting alcohol and high-purine foods, staying well hydrated, and managing conditions such as hypertension, diabetes, and kidney disease are important. Regular follow-up and monitoring of serum uric acid levels help guide long-term treatment.

Avoid quick-fix claims

No instant cure

There is no guaranteed 10-minute gout cure. Quick symptom relief is different from lowering urate and preventing future attacks, so do not self-start or stop gout medication without medical advice.

Prevention

Can Gout Be Prevented?

  • Take prescribed urate-lowering treatment consistently, even when symptoms improve.
  • Attend monitoring visits so treatment and uric acid levels can be reviewed.
  • Maintain a healthy weight through gradual, sustainable changes when appropriate.
  • Stay hydrated unless your clinician has given you different fluid guidance.
  • Limit alcohol and sugar-sweetened drinks.
  • Manage blood pressure, diabetes, and kidney disease with appropriate medical care.

Outlook and Prognosis

Outlook and Prognosis for Gout

An untreated gout attack may settle temporarily, but attacks can become more frequent and damaging over time. Consistent treatment can lower uric acid, prevent flares, shrink tophi, and help protect joints. Gout is usually manageable when long-term urate control and follow-up care are maintained.

When Should You See a Doctor

When Should You See a Doctor for Gout?

  • Seek medical advice for a first-ever sudden, painful, swollen joint.
  • Arrange an evaluation for repeated or worsening attacks.
  • Contact a clinician if symptoms do not improve with the treatment plan.
  • Ask for care if you notice tophi or have symptoms of kidney stones.
  • Speak with your care team if you are having trouble taking prescribed medicines.

Get urgent medical care

Urgent joint evaluation

Seek urgent evaluation for a hot, swollen joint with fever, chills, feeling very unwell, rapidly worsening pain, or inability to move the joint. A serious joint infection can resemble gout and needs prompt treatment.
