Hyperuricaemia or hyperuricemia is an abnormally high level of uric acid in the blood.In the pH conditions of body fluid, uric acid exists largely as urate, the ion form. [1] [2] Serum uric acid concentrations greater than 6 mg/dL for females, 7 mg/dL for males, and 5.5 mg/dL for youth (under 18 years old) are defined as hyperuricemia. [3]
Hyperuricemia (high levels of uric acid), which induces gout, has various potential origins: Diet may be a factor. High intake of dietary purine, high-fructose corn syrup, and sucrose can increase levels of uric acid. [36] [37] Serum uric acid can be elevated by reduced excretion via the kidneys. [38]
Rates are high among Polynesians, but the disease is rare in aboriginal Australians, despite a higher mean uric acid serum concentration in the latter group. [108] It has become common in China , Polynesia , and urban Sub-Saharan Africa . [ 5 ]
Written by five-time New York Times bestselling author David Perlmutter, M.D., Drop Acid suggests that high levels of uric acid, an overlooked “waste product” of metabolism, can lead to many ...
[citation needed] The urinalysis may show uric acid crystals or amorphous urates. [citation needed] The hypersecretion of uric acid can be detected with a high urine uric acid - creatinine ratio > 1.0, compared to a value of 0.6–0.7 for most other causes of acute kidney failure. [citation needed]

Acute uric acid nephropathy is caused by deposition of uric acid crystals within the kidney interstitium and tubules, leading to partial or complete obstruction of collecting ducts, renal pelvis, or ureter. This obstruction is usually bilateral, and patients follow the clinical course of acute kidney failure.
Hyperuricosuria is a medical term referring to the presence of excessive amounts of uric acid in the urine. For men this is at a rate greater than 800 mg/day, and for women, 750 mg/day. [1] Notable direct causes of hyperuricosuria are dissolution of uric acid crystals in the kidneys or urinary bladder, and hyperuricemia.
