<Tr> <Td_colspan="2"> Uric acid </Td> </Tr> <Tr> <Th> Specialty </Th> <Td> Endocrinology </Td> </Tr> <P> 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 . The amount of urate in the body depends on the balance between the amount of purines eaten in food, the amount of urate synthesised within the body (e.g., through cell turnover), and the amount of urate that is excreted in urine or through the gastrointestinal tract . In humans, the upper end of the normal range is 360 μmol / L (6 mg / dL) for women and 400 μmol / L (6.8 mg / dL) for men . </P> <P> Many factors contribute to hyperuricemia, including genetics, insulin resistance, iron overload, hypertension, hypothyroidism, hyperthyroidism, renal insufficiency, obesity, diet, use of diuretics (e.g. thiazides, loop diuretics), and consumption of excess alcoholic beverages . Of these, alcohol consumption is the most important . </P>
