Gout is a type of arthritis that results from the deposit and build-up of glass-like crystals of uric acid in your joints. Uric acid is a by-product of the breakdown of waste products in your body called purines. Normally, uric acid is broken down in the blood stream and then eliminated in the urine.
When the body increases its production of uric acid, or the kidneys remove less uric acid than normal, an excess of uric acid results. High levels of uric acid in the blood (hyperuricemia) may lead to gout, although most people with this condition will not develop the symptoms of gout. Conversely, people without hyperuricemia can develop gout.
It is estimated that over 2 million Americans have gout. A severe gout attack is extremely painful and, if left untreated, can cause permanent and severe joint damage. Fortunately, gout can be medically managed or controlled.

What is it like to live with gout?
A risk factor is something that increases your likelihood of getting a disease or condition.
It is possible to develop gout with or without the risk factors listed below. However, the more risk factors you have, the greater your likelihood of developing gout. If you have a number of risk factors, ask your doctor what you can do to reduce your risk.
Risk factors for gout include:
Age and Gender
Although gout can occur in men and women of any age, it most often occurs in men over age 40. Gout usually does not affect women until after menopause.
Lifestyle Factors
Lifestyle factors that increase the risk of gout include:
Genetic Factors
There appears to be a genetic component to gout. Six percent to eighteen percent of people who have gout have relatives who also have gout. In a small number of people, the risk of gout is increased by an enzyme defect that interferes with the way the body breaks down purines.
Medical Conditions
Serious illness, such as heart attack or stroke , can trigger a gout attack. Other illnesses that may increase the risk for developing gout include:
Medical Treatments
Certain medications and vitamins can increase the risk of gout. These include:
In addition, surgery, trauma, and cancer treatments such as radiation or chemotherapy may also increase your risk of developing gout.
The symptoms of gout usually come on suddenly and severely. A gout attack usually affects only one joint, most commonly, the joint of the big toe. However, the attack may involve more than one joint. Symptoms frequently develop overnight and worsen over the next 24 to 36 hours. Other affected joints include the knees, ankles, feet, wrists, hands, fingers, and elbows.

Symptoms in the joint affected usually include:
Other symptoms may include:
Symptoms are usually more severe in people who develop gout before age 30. Some people will only suffer one gout attack. Most people with gout, however, will suffer a recurrence within two years of the first attack, and further recurrences after that (if the condition is left untreated).
Possible complications of gout include:
Your doctor will ask about your symptoms and medical history. A physical exam will be done. Gout can be difficult to diagnose. The symptoms are often similar to those of other conditions. If gout is suspected, tests may include:
Arthrocentesis (Joint Aspiration)—A needle is inserted into a joint and fluid is withdrawn with a syringe. This is usually performed using local anesthesia. The fluid is then checked under a microscope for uric acid crystals and signs of inflammation. In nearly all cases of gout, uric acid crystals are present.
Blood and Urine Tests—These tests assess kidney function and measure the amount of uric acid in your blood and urine. However, uric acid levels can often be normal during a gout attack. Other blood tests check for white blood cell count and sedimentation rate.
X-rays—X-rays may be performed to check for signs of joint damage, which may be present in recurrent cases of gout.

There are a number of measures that will help prevent gout from developing or prevent recurrence of gout attacks.
Avoid Food High in Purines
Gout pain is caused by glass-like crystals of uric acid that build-up in your joints. Uric acid is a by-product of the breakdown of waste products called purines. Therefore, one of the main treatments for gout is to avoid foods and beverages that are high in purines. These include:
Organ meats, such as:
Legumes, such as:
Alcoholic beverages, especially:
The severity of gout varies from person to person. Talk with your doctor about how strict your diet should be for your individual situation.
Drink Plenty of Fluids
Fluids help flush uric acid from the body, so drinking lots of fluids can help control and prevent recurrence of gout attacks.
Lose Weight and Maintain an Appropriate Weight
Losing weight can help lower uric acid levels. If you are overweight, losing weight should help reduce your symptoms and prevent future gout attacks. However, do not go on a crash diet because this can make your gout worse. Consult your doctor for help designing a safe and effective weight loss program that includes:

ACR is a professional organization of rheumatologists and associated health professionals, including physicians, research scientists, nurses, physical and occupational therapists, psychologists, and social workers. The ACR seeks to increase research in the rheumatic diseases, increase federal funding for research in the rheumatic diseases, and advocate for public policy relating to the care of people with arthritis and other rheumatic diseases.
The purpose of screening is early diagnosis and treatment. Screening tests are usually administered to people without current symptoms, but who may be at high risk for certain diseases or conditions.
Screening Guidelines
Generally, people are not screened for gout. However, according to the American Association for Clinical Chemistry, in some cases when people are undergoing chemotherapy or radiation therapy , blood tests to screen for elevated uric acid levels may be ordered. An increased level of uric acid in the blood increases the risk of developing gout.
