Gout - Lifestyle Changes

Complications


Properly treated gout rarely poses a long-term health threat, though it can be a cause of short-term pain and incapacity for thousands of Americans.

Pain and Disability

Left untreated, gout can develop into a painful and disabling chronic disorder. Persistent gout can destroy cartilage and bone, causing irreversible joint deformities and loss of motion. Survey results released in 2006 show that two-thirds of persons with gout consider the pain of attacks among the worst they've ever experienced. An estimated 75% of those surveyed said flare-ups made walking very difficult, and about 70% reported trouble putting on shoes or playing sports.

Tophi are firm chalky, gritty clumps of uric acid crystals that build up in tissue surrounding a joint. If gout is not treated, tophi can grow to the size of golf balls and can destroy bone and cartilage in the joints, similar to the process in rheumatoid arthritis. If they lodge in the spine, tophi can cause serious damage including compression, although this is very rare. In extreme cases, joint destruction results in complete disability.

Kidney Conditions

Kidney Stones. Kidney stones occur in 10 - 40% of gout patients, and can occur at any time after the development of hyperuricemia. Although the stones are usually composed of uric acid, they may also be mixed with other materials.

Nephrolithiasis
Kidney stones result when urine becomes too concentrated, and substances in the urine crystallize to form stones. Symptoms occur when the stones begin to move down the ureter and cause intense pain. Kidney stones may form in the pelvis or calyces of the kidney or in the ureter.

Kidney Disease. About 25% of patients with chronic hyperuricemia develop progressive kidney disease, which sometimes ends in kidney failure. It should be noted, however, that many experts believe that chronic hyperuricemia is unlikely to be a common cause of kidney disease. In most cases, the kidney disease comes first and causes high concentrations of uric acid.

Gout and Heart Disease

Gout is found in higher rates in people with high blood pressure, coronary artery disease, and heart failure. Hyperuricemia, in fact, has been associated with a higher risk of death from heart conditions. Studies also found an association between gout and having the metabolic syndrome -- a collection of problems, such as abdominal obesity, high blood pressure, high triglycerides levels, and low "good" cholesterol levels. This syndrome increases a person's risk of heart disease and diabetes.

According to some studies, hyperuricemia may be associated with heart disease, but there are not enough data to confirm such an association.

Other Medical Conditions Associated with Gout

The following are some conditions that are associated with long-term gout:

  • Cataracts
  • Dry eye syndrome
  • Complications in the lungs (in rare cases, uric acid crystals occur in the lungs)
