High uric acid is a high level of uric acid in the human blood, >360 μmol/L in women and >420 μmol/L in men. If only high uric acid is present, the diagnosis is hyperuricemia. If there is redness, swelling, pain and even gout stones in the joints, the diagnosis is gout. The treatment for high uric acid is as follows: 1. reduce the intake of foods with high purine content; 2. insist on exercise and weight control; 3. drink more water to increase urine volume and alkalize urine; 4. lower uric acid medication, such as allopurinol, benzbromarone, febuxostat, etc.; 5. intake of foods that lower uric acid: like celery is rich in potassium and also has a strong diuretic effect, which can promote uric acid excretion. Tomatoes are alkaline food, which can help eliminate uric acid in the blood, and also can alkalize urine and promote uric acid excretion. Black foods such as black sesame can promote uric acid excretion and play a role in lowering uric acid. In addition, eat more fresh vegetables and fruits.
