Gout

Overview

Gout is a common form of inflammatory arthritis that can cause sudden episodes of pain, swelling, redness and warmth in a joint. It occurs when a substance called uric acid builds up in the blood and forms tiny crystals in or around the joints. These crystals can trigger strong inflammation, often called a gout attack or flare.

Gout most often affects the big toe, but it can also involve the ankles, knees, wrists, fingers or elbows. Some people have only occasional attacks, while others may develop repeated flares or ongoing joint problems if uric acid levels remain high over time.

Although gout can be very painful, it is a manageable condition. With medical evaluation, lifestyle guidance and appropriate treatment when needed, many people can reduce the frequency and severity of attacks and protect their joints.

Symptoms

Gout symptoms often start suddenly, sometimes during the night. A flare may develop quickly and feel intense within a few hours. Symptoms can include:

• Severe joint pain, commonly in the big toe
• Swelling and tenderness around the affected joint
• Red or shiny skin over the joint
• Warmth in the affected area
• Difficulty walking or using the joint
• Lingering discomfort after the most intense pain improves

Between attacks, some people have no symptoms. In long-standing or poorly controlled gout, firm lumps of uric acid crystals, called tophi, may develop under the skin, often around the fingers, toes, elbows or ears. These are usually not an early sign but can occur in chronic cases.

Causes and Risk Factors

Gout is linked to high levels of uric acid in the blood. Uric acid is produced when the body breaks down purines, which are natural substances found in the body and in certain foods. Normally, uric acid dissolves in the blood and leaves the body through the kidneys in urine. If the body produces too much uric acid or the kidneys remove too little, uric acid can accumulate and form crystals.

Several factors may increase the risk of gout, including:

• Family history of gout
• Kidney disease or reduced kidney function
• Being overweight or having metabolic health conditions
• High blood pressure
• Diabetes or insulin resistance
• Certain heart and vascular conditions
• Alcohol intake, especially frequent or heavy use
• Regular consumption of foods high in purines, such as some red meats, organ meats and certain seafood
• Sugary drinks and foods high in fructose
• Some medications that affect uric acid levels
• Recent surgery, illness, dehydration or sudden changes in diet

Having risk factors does not mean a person will definitely develop gout. Likewise, gout can occur in people without obvious risk factors. A medical assessment helps identify individual contributors and guide prevention.

Diagnosis

A doctor usually begins by asking about symptoms, the pattern of attacks, medical history, diet, medications and family history. A physical examination of the affected joint is also important.

Tests may be used to support the diagnosis and rule out other conditions, such as infection, injury or other types of arthritis. These tests may include:

• Blood tests to measure uric acid levels and assess kidney function
• Joint fluid analysis, where a small sample of fluid is taken from the swollen joint to look for uric acid crystals
• Imaging tests, such as ultrasound or X-ray, in selected cases

A high uric acid level can support the diagnosis, but it does not always confirm gout by itself. Some people have high uric acid without symptoms, and uric acid levels may be normal during an acute flare. For this reason, diagnosis is based on the full clinical picture.

Treatment Options

Treatment for gout has two main goals: to relieve pain and inflammation during a flare, and to reduce uric acid levels over time when needed. The best plan depends on the person’s symptoms, general health, kidney function, other medical conditions and how often attacks occur.

During a flare, doctors may recommend medicines that reduce inflammation and pain. Resting the affected joint and avoiding pressure on it may also help while symptoms are severe. It is important not to start, stop or change any medication without medical advice, especially for people with kidney disease, stomach problems, heart conditions or those taking other medicines.

For people with frequent attacks, tophi, kidney stones or persistently high uric acid levels, long-term urate-lowering treatment may be considered. These medicines aim to lower uric acid and prevent crystal buildup. They are usually monitored with blood tests and medical follow-up.

Lifestyle changes can support gout management. These may include maintaining a healthy weight, drinking enough fluids, limiting alcohol, reducing sugary drinks, and moderating foods that are high in purines. A balanced diet is usually preferred over extreme dietary restriction. People with gout may benefit from individualized advice, especially if they have kidney disease, diabetes, high blood pressure or other chronic conditions.

When to See a Doctor

Seek medical advice if you have sudden, severe joint pain, especially if the joint is swollen, red or warm. Prompt evaluation is important because gout can resemble other conditions, including joint infection, which may need urgent care.

You should also see a doctor if gout attacks keep returning, symptoms do not improve as expected, pain affects daily activities, or you notice lumps under the skin around joints. People with kidney disease, kidney stones, diabetes, high blood pressure or heart disease should discuss gout symptoms with a healthcare professional.

If you have fever, feel generally unwell, cannot move the joint, or the skin around the joint is very hot and painful, seek urgent medical attention. Early assessment can help identify the cause and guide safe, appropriate treatment.
