Gout attacks are associated with high uric acid. When uric acid becomes supersaturated in the body, the blood is unable to dissolve the excess uric acid and urates precipitate as crystals and are deposited in the more terminal parts of the limbs, causing pain, redness and swelling in the surrounding tissues and restricted movement. Prolonged high uric acid may also cause gout stones and even irreversible joint damage, so aggressive treatment of gout is necessary. In the acute phase of gout, pain relief is needed quickly and can be treated with oral colchicine or non-steroidal drugs. During the remission period of gout, it is necessary to actively lower uric acid, and only when uric acid is controlled in the normal range, can we avoid further attacks of gout. Because uric acid is produced after the metabolism of purine substances in the body, it is important to avoid eating foods containing too much purine in daily life and to drink more water to promote the excretion of uric acid. If uric acid cannot be controlled within the normal range through diet, treatment with uric acid-lowering drugs is also necessary.
