| Risk Factors
Gout occurs when uric acid crystals build up in the joints. This causes the joints to be inflamed, causing pain.
Gout typically occurs if you have high levels of
in your blood. A high level of uric acid in the blood is identified by the term hyperuricemia. However, you could also have normal uric levels and still have gout.
The uric acid can then form crystals in the joints causing the pain and inflammation.
The liver metabolizes uric acid, and the kidneys get rid of it through the urine. Levels of uric acid build up when:
- Too much uric acid is produced
- Not enough uric acid is eliminated
If you have gout and hyperuricemia, your body doesn't eliminate enough uric acid.
Gout is more common in men over the age of 30 years, but gout can occur in men and women at any age. Other factors that may increase your risk of gout include:
, sudden weight gain, or rapid weight loss
- Family members with history of gout
- Diabetes mellitus
High blood pressure
Certain types of
Certain medications, such as:
- Low-dose aspirin
- Cyclosporin, an antirejection drug
drugs used to treat cancer
Certain foods and beverages may also increase your chances of gout.
- Foods high in purines, such as organ meats, shellfish, some vegetables, and gravies.
- High-fructose drinks, such as sugar-sweetened sodas and orange juice
alcohol, especially beer
- Binge drinking
Symptoms may include:
- Sudden onset of severe pain in an inflamed joint, usually starting in the big toe
- Joints that are red, hot, swollen, and very tender
- Increased pain 24-48
hours after the onset of symptoms

Most people with gout have another attack. This attack may affect many different joints. With recurrent gout, tophi can form. Tophi are chalky deposits of uric acid that commonly occur in the elbows and earlobes.
Gout can also lead to other health problems, such as:
The doctor will ask about your symptoms and medical history. A physical exam will be done. A sample of fluid from the affected joint will be taken. This fluid will be tested for uric acid crystals.
Other tests may include:
- Blood and urine tests—to measure the level of uric acid in your blood and to assess kidney function
Treatment depends on whether the gout is acute or recurrent.
In general, the sooner treatment begins for an acute attack, the more effective it is. Treatment
- Number of joints affected
- Previous responses to treatment
- Overall health
an ice pack on the joint may ease the pain. Keeping the weight of clothes or bed covers off the joint can also help.
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Corticosteroids—may be given orally or as an injection into the affected joint
- Consume a low-purine diet.
- Avoid alcohol.
- If you're overweight, lose weight gradually. Rapid weight loss can cause a gout attack.
- Ask your doctor if any of your medications can cause high uric acid levels.
- Drink a lot of fluids throughout the day.
If you have recurrent gout, or you have kidney stones, tophi, or reduced kidney function, you may be given medications:
- To lower the production of uric acid
- To increase the excretion of uric acid by the kidneys
- To convert uric acid into a different byproduct
To help reduce your chance of getting gout:
- Eat a low-purine diet.
- Limit how much alcohol you drink. Avoid binge drinking.
- Drink a lot of fluids.
- Lose weight gradually.
