High uric acid cannot be stopped after it is lowered by taking medication. Once the medication is stopped, the blood uric acid level will rebound again. The main reasons for elevated blood uric acid levels in the body are as follows: First, excessive sources of uric acid. Secondly, the excretion of uric acid is dysfunctional. Generally speaking, the excretory dysfunction of uric acid is difficult to reverse, so in order to reduce blood uric acid, we have to start by inhibiting the source of uric acid. The sources of uric acid are mainly divided into exogenous sources and endogenous sources, exogenous sources are mainly through dietary intake, accounting for about 30% of the sources of uric acid, while endogenous sources are mainly from the metabolites of the body’s metabolic process, mainly accounting for 70%. Therefore, as long as the body is carrying out normal metabolism, it will continuously produce blood uric acid, and the uric acid excretion function is out of order, so once the drug is stopped, the blood uric acid level will definitely rise.
