Hyperuricemia and gout can be considered as different stages of a disease.
When the blood uric acid is measured twice on the same day above 420 μmol/L, it is considered to be hyperuricemia.
Uric acid in the human body is too high for a long time, forming crystals, crystallization under various triggers, such as diet, dehydration, trauma, fatigue, drugs, etc., easy to deposit in the joints, around the joints may cause inflammatory reactions, gout.
Gout attacks are manifested as acute redness, swelling, heat and pain in the joints, commonly found in the big toe joints, insteps, ankles, knees, etc.
In addition to deposition of uric acid in the joints and causing gout attacks, uric acid forms urate crystals in the kidneys, or uric acid stones, which may also cause chronic uric acid kidney disease.
In addition, hyperuricemia is also a risk factor for many other metabolic diseases, such as coronary heart disease, hypertension, atherosclerosis, etc., which are actually mutually reinforcing and influencing each other.
