Internal causes: First, when the body is injured by a fall, the cells with impaired metabolism decompose the nucleic acid in the nucleus, and the nucleic acid is metabolized into purine, which is then metabolized into uric acid. Second, exercise makes the body produce lactic acid. Lactic acid and nucleic acid are both acidic substances. The excretory passage of the body is squeezed by lactic acid, which temporarily increases uric acid, and the same situation will occur when drinking.

External cause: eating too much food containing purine. Eat more fruits and vegetables and less seafood. Two thirds of uric acid is produced by the body's own metabolism. One third was eaten.

In order to prevent problems with uric acid, prevent it before you get sick. If it is prevented, it can be done by licking your stomach.
