High uric acid generally refers to a higher than normal level of uric acid in the blood of the body. High uric acid is mainly due to the following reasons, the metabolism of purine substances in the body is disturbed, resulting in an increase in the synthesis of uric acid. For example, excessive intake of exogenous purines and excessive production of endogenous purines. In addition, a decrease in uric acid excretion in the body can also lead to an increase in uric acid. These include inhibition of renal tubular secretion, reduced glomerular filtration rate, and increased renal tubular reabsorption. Treatment of mild hyperuricemia can start with dietary control and exercise; if it is not effective or is accompanied by hypertension, diabetes and cardiovascular disease, you should take uric acid medications such as benzbromarone or allopurinol or febuxostat for control.
