Uric acid in the clinic mainly refers to blood uric acid, and blood uric acid 660μmol/L is more serious for both men and women. The normal uric acid level is no more than 420μmol/L for men and 360μmol/L for women. therefore, blood uric acid 660μmol/L has been elevated more obviously, and patients need to strictly control diet, improve lifestyle habits, and take medication under the guidance of doctors. Many studies now suggest that hyperuricemia is closely related to diabetes mellitus, hypertension and coronary heart disease. When the blood uric acid is 660μmol/L, it is already at a relatively high level. At this time, it may cause the precipitation of urate crystals due to the elevated blood uric acid, which will be deposited in the joints and will lead to gouty arthritis and joint deformation, and it will also be deposited in the kidneys, which will cause gouty nephropathy, uric acid stones, and even induce uremia. It can also stimulate the walls of blood vessels, leading to atherosclerosis and inducing or aggravating coronary heart disease and cerebrovascular disease. It may also damage the pancreatic beta cells of the pancreas and induce or aggravate diabetes. Therefore, for patients with blood uric acid 660μmol/L, they should be treated actively. They need to strictly control their diet, limit the intake of high purine foods, such as animal offal, fish and shrimp, clams and crabs, strictly avoid alcohol, eat a light, easy-to-digest diet, and avoid spicy and stimulating foods, such as chili peppers. It is also necessary to control weight and drink more water, usually it is recommended to drink more than 2000ml of water per day. For patients with blood uric acid of 660 μmol/L, combined with diabetes, hypertension and coronary heart disease, it is necessary to actively initiate drug therapy, often choosing drugs such as benzbromarone and allopurinol, in order to reduce blood uric acid concentration and prevent crystallization formation.
