Causes Of Gout

Overview

Gout is a type of arthritis that happens when too much uric acid builds up in the body and forms sharp crystals inside a joint. This causes sudden, severe pain, swelling, and redness, often in the big toe.

Gout is quite common. It is the most common type of inflammatory arthritis in men, and it affects many people around the world, especially as they get older.

Gout happens more often in men, usually between 30 and 50 years old. Women are more likely to develop gout after menopause. People with certain health conditions like high blood pressure, diabetes, kidney disease, or obesity have a higher risk.

Symptoms

Common symptoms

• Sudden, intense joint pain, often waking you from sleep
• Swelling and tenderness in the joint
• Redness and a feeling of heat around the joint
• Difficulty moving the joint normally
• Pain that lasts for a few hours, then fades but may come back
• In some cases, the skin around the joint may peel and feel itchy

Causes

Main causes

• Too much uric acid in your blood, a condition called hyperuricemia
• Your body producing more uric acid than it can remove
• Your kidneys not removing uric acid quickly enough
• Eating foods high in purines, which break down into uric acid (like red meat, shellfish, and organ meats)
• Drinking sugary drinks or alcohol, especially beer, which can raise uric acid levels
• Certain medicines, such as water pills (diuretics), that can raise uric acid levels

Risk factors

• Being male
• Having a family history of gout
• Being overweight or obese
• High blood pressure
• Diabetes or prediabetes
• Kidney disease
• Taking medicines like diuretics or low-dose aspirin
• Drinking alcohol, especially beer
• Eating a diet high in red meat and shellfish
• Having undergone an organ transplant

When to see a doctor

See a doctor urgently if:

• If you have a painful, swollen joint and a fever
• If the joint looks hot and red and you feel generally unwell
• If you cannot move the joint or put any weight on it

Book a routine appointment if:

• If you have repeated attacks that last more than a day or two
• If you notice firm, painless lumps under the skin near your joints
• If you have long-term joint pain that is not going away
• If you want to start a long-term treatment to prevent gout attacks

Diagnosis

To diagnose gout, a doctor will review your medical history and symptoms, and examine the joint. They will also look for risk factors and may order a blood test to check uric acid levels, although some people with gout have normal blood uric acid levels.

Tests that may be done

• Blood test to measure uric acid level
• Joint fluid test, where a needle is used to withdraw a small sample of fluid from the swollen joint to look for uric acid crystals
• Ultrasound or CT scan to look for crystals or joint damage

What to expect at your appointment

During your visit, the doctor will ask about your diet, alcohol use, family history, and any medicines you take. They may need to do a joint aspiration, which sounds scary but is a quick procedure done with numbing medicine. The sample is sent to a lab to confirm whether gout crystals are present. This is the most reliable way to diagnose gout.

Treatment

Treatment for gout has two main goals: to relieve the pain during an attack, and to prevent future attacks by lowering the amount of uric acid in your blood. Your doctor will recommend a plan that fits your health needs.

Self-care at home

• Rest the affected joint and keep it raised on a cushion or pillow
• Apply an ice pack wrapped in a cloth for 15–20 minutes at a time to reduce swelling and pain
• Drink plenty of water to help your kidneys flush out uric acid
• Avoid alcohol and sugary drinks during and between attacks
• Avoid eating foods high in purines, like red meat, shellfish, and organ meats
• Try to keep the bedding off the tender joint at night to avoid pressure

Medical treatments

For an acute attack, a doctor may prescribe a short course of an anti-inflammatory medicine or a steroid to reduce pain and swelling. For people with repeated attacks, doctors may recommend medicine taken daily to lower uric acid levels, or a medicine that helps the kidneys get rid of uric acid. It is important to take medicines exactly as prescribed and to talk with your doctor about any concerns.

When is surgery considered?

Surgery is rarely needed for gout. In very advanced cases, large tophi (uric acid crystal deposits) may need to be removed, or a joint severely damaged by gout may need repair or replacement. This is only considered when other treatments have not worked.

Living with this condition

Living with gout means learning to manage sudden attacks and making everyday choices to lower uric acid levels. Keep a simple action plan ready: know your trigger foods, stay hydrated, and keep a record of your attacks so you can recognize patterns. Follow up with your doctor to adjust your treatment as needed.

Lifestyle tips

• Maintain a healthy weight, but lose weight slowly — crash dieting can raise uric acid
• Stay well-hydrated by drinking water throughout the day
• Limit alcohol, especially beer and spirits
• Choose low-purine proteins like eggs, dairy, and most vegetables
• Avoid sugary drinks and foods with high fructose corn syrup
• Exercise regularly, but avoid stressing joints that are already swollen or painful

Diet and exercise

A balanced diet low in purines and regular physical activity can help control gout. Focus on fruits, vegetables, whole grains, low-fat dairy, and lean proteins. Gentle exercises like walking, swimming, and cycling are easier on the joints. If you have an attack, rest the joint until the pain resolves, then slowly return to activity.

Mental health and emotional wellbeing

Living with a condition that causes sudden, severe pain can be stressful and sometimes depressing. It is normal to worry about when the next attack might happen. Talk to your doctor if pain is affecting your mood, sleep, or daily life. Seeking support from friends, family, or a counselor can help you stay positive.

Prevention

Yes, gout attacks can often be prevented. The most important steps are keeping uric acid levels in a healthy range through medication if prescribed, staying hydrated, and making long-term changes to your diet and drinking habits. Losing weight gradually and managing conditions like high blood pressure or diabetes also help.

Vaccines

There are no vaccines to prevent gout. However, some medicines used for gout may affect your immune system, so it's important that your vaccines are up-to-date. Talk to your doctor about safe immunization.

Screening programmes

Screening for gout is not routine for everyone, but if you have risk factors like obesity, high blood pressure, or a family history of gout, your doctor may check your uric acid level during a regular visit.

Complications

If left untreated

• More frequent and longer-lasting attacks
• Damage to the joint, leading to chronic arthritis
• Formation of tophi, which are lumps of uric acid crystals under the skin
• Kidney stones from uric acid crystals
• Reduced function of the kidneys over time

Long-term outlook

The outlook for gout is very good. With proper treatment and lifestyle choices, most people can control their symptoms, avoid joint damage, and live an active, full life. You can work with your doctor to find a plan that fits you.
