Elevated uric acid levels may be caused by alcoholism, diabetes, chemotherapy, gout or hyperparathyroidism. Chemotherapy, leukemia, kidney problems, lead poisoning and excessive exercise may also cause uric acid levels to rise, according to MedlinePlus. Uric acid levels in the blood normally range from 3.5 to 7.2 milligrams per deciliter.
Because uric acid is created when the body breaks down purines, consuming a diet that is high in purines can also lead to high uric acid levels. Purines are found in beer, liver, anchovies, and dried beans and peas, according to MedlinePlus. Uric acid is filtered through the kidneys and exits the body through urine.
