Once the uric acid is lowered enough for a prolonged period , the preventive medication can be stopped. Your doctor may use a sterile needle to remove a sample of fluid from your inflamed joint. This joint fluid will be examined in a laboratory for microscopic uric acid crystals, which confirm the diagnosis of gouty arthritis. Your doctor also may order blood tests to assess the function of your kidneys and to measure the level of uric acid in your blood.

How does gout affect the body?

Gout causes intense pain and swelling around one or more joints. Gout most commonly affects the joint at the base of the big toe. The signs and symptoms of gout almost always occur suddenly, and often at night.

Gout is partly genetic, contributing to about 60% of variability in uric acid level. The SLC2A9, SLC22A12, and ABCG2 genes have been found to be commonly associated with gout and variations in them can approximately double the risk. Loss-of-function mutations in SLC2A9 and SLC22A12 causes low blood uric acid levels by reducing urate absorption and unopposed urate secretion. Low daily doses might be prescribed to prevent future attacks. Corticosteroids, such as prednisone, can be prescribed to reduce pain and inflammation. They can increase blood sugar levels and blood pressure and may induce mood changes.

Is It Psoriatic Arthritis, Gout, Or Something Else?

If gout is not treated, the inflammation can cause damage to joints and tendons. Crystal deposits on tendons can cause the skin to wear down, which can lead to infection. In addition, tendons can tear, which can lead to loss of function. "Trying to lose weight by fasting can put you at risk of gout attack," Dr. Vanitallie says. Aim to drink around eight cups of water a day, Dr. Vanitallie says, especially if you have already had a gout attack or have other risk factors.

Patients with severe hyperuricemia should avoid foods with high purine content. Early recognition of acute gout attacks is critical, in that intervention with medication is much more effective earlier in the attack. Individual gout flares are often triggered by acute increases or decreases in urate levels that may lead to the production, exposure, or shedding of crystals. Changes in urate levels can result from acute alcohol ingestion, acute overindulgence in foods high in purines, rapid weight loss, dehydration, or trauma. Usually non-steroidal anti-inflammatory medications are be used to treat gout.

But the most important fork in the road for gout sufferers is whether to start taking a drug that will lower their uric acid levels. Once people start taking these drugs, they usually must take them for the rest of their lives. Going on and off a uric acid–lowering medication can provoke gout attacks. Guidelines also recommend uric acid-lowering treatment if a person with gout also has kidney disease.

Key Points About Gout

A doctor may extract a sample of joint fluid so it can be examined under a microscope for any presence of urate crystals, according to the NIAMS. The Gout Education Society notes that insulin resistance can lead to gout and having too-high levels of uric acid in your blood can lead to insulin resistance. The group reports that 26% of people with gout have Type 2 diabetes. In a 2010 study, Kuo et al demonstrated that gout, but not hyperuricemia, is associated with higher risk of death from all causes and cardiovascular diseases. Among individuals with hyperuricemia, the HR of all-cause mortality was 1.07 and the adjusted HR of cardiovascular mortality was 1.08. If attacks recur, successful uric acid adjustment (requiring lifelong use of urate-lowering medication) usually suppresses further activity.

Metabolic syndrome is a collection of health problems, such as abdominal obesity, high blood pressure, and low cholesterol. This syndrome increases a person's risk for heart disease and stroke. Therefore, lifestyle changes are an important aspect of preventing gout and improving overall health. Acute gouty arthritis occurs when the first symptoms of gout appear.

Adjusted risk of a CV event was 49% lower with colchicine use (HR 0.51) and all-cause mortality was 73% lower (HR 0.55). In contrast, urate-lowering therapy in patients with gout has been linked to reduced risk for both cardiovascular mortality and all-cause mortality. Overproduction of uric acid may also occur in disorders that cause high cell turnover with release of purines that are present in high concentration in cell nuclei. These disorders include myeloproliferative and lymphoproliferative disorders, psoriasis, and hemolytic anemias. Cell lysis from chemotherapy for malignancies, especially those of the hematopoietic or lymphatic systems, can raise uric acid levels, as can excessive exercise and obesity.

Preventing An Attack During Travel

They also will examine the affected joint and may take a fluid sample from the joint to look for uric acid crystals. Left untreated, gout can develop into a painful and disabling chronic disorder. If gout is not treated, tophi can grow to the size of golf balls and destroy bone and cartilage in the joints. In very severe cases, joint destruction results in complete disability. When gout remains untreated, the periods between attacks of acute gout become shorter and shorter and the attacks, although sometimes less intense, can last longer. In about 10 to 20 years gout becomes a chronic disorder with constant low-grade pain and mild or acute inflammation.

Some attacks last only hours, while others go on for as long as several weeks. Though symptoms can subside, the crystals are still present and future attacks are likely to occur. The enzyme responsible for production of uric acid from purines is xanthine oxidase.

These drugs may be used long-term or for a person's lifetime. Gout is a disorder in which deposits of uric acid crystals accumulate in the joints because of high blood levels of uric acid . The accumulations of crystals cause flare-ups of painful inflammation in and around joints.

Certain foods are also high in purines, which can lead to high uric acid levels or cause an overproduction of uric acid. A plant extract, it's been used to treat gout for 2,000 years, says Reveille. Colchicine works within several minutes to several hours to block gout inflammation. The sooner you start it, the more likely the attack will resolve quickly. An injected steroid also tackles inflammation, usually controlling pain and swelling within 24 hours. Often people with gout also experience symptoms that affect the entire body, such as mild fever, chills and a feeling of being unwell.

Uric acid is formed when proteins in the food we eat, called purines, are broken down. Therefore, there has been a great deal of interest in dietary management of gout by avoiding high-purine (purine-rich) foods. However, a diet very low in purines is extremely difficult to follow, because purines are a natural part of many healthy foods. Even when a diet very low in purines is followed strictly, the uric acid level in the bloodstream is only slightly lowered.

Talk to your doctor.You can play an active role in controlling your arthritis by attending regular appointments with your health care provider and following your recommended treatment plan. This is especially important if you also have other chronic conditions, like diabetes or heart disease. Asparagus, beans, some other plant-based foods, and mushrooms are also sources of purines, but research suggests that these do not trigger gout attacks and do not impact uric acid levels. This stage is the period in between attacks of acute gout. Subsequent flares may not occur for months or years, though if not treated, over time, they can last longer and occur more frequently. During this interval, further urate crystals are being deposited in tissue.

Gout occurs more often in men, primarily because women tend to have lower uric acid levels. After menopause, however, women's uric acid levels approach those of men. Men are also more likely to develop gout earlier — usually between the ages of 30 and 50 — whereas women generally develop signs and symptoms after menopause. Gout is a common and complex form of arthritis that can affect anyone. It's characterized by sudden, severe attacks of pain, swelling, redness and tenderness in one or more joints, most often in the big toe.

This situation has been mimicked in more recent times when imbibers of “moonshine whiskey,” often made in radiators containing lead, developed a lead poisoning-associated gout (“Saturnine gout”). The prosperous and overweight burgher with gout is a classical European image of the 19th century, but in reality gout affects those of all economic classes. Gout occurs when surplus uric acid coalesces into crystals, which causes inflammation in the joints. Left untreated, patients may suffer from recurrent painful and disabling acute attacks of gout. However, excellent treatments for gout are available, and most patients respond very well to gout treatment with a good prognosis.
