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 uric acid 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:
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:
Certain foods and beverages may also increase your chances of gout.
Symptoms may include:
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:
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 depends on:
Putting an ice pack on the joint may ease the pain. Keeping the weight of clothes or bed covers off the joint can also help.
