The claim that high uric acid is due to not drinking enough water is false. Insufficient water intake may have a certain impact on the results of uric acid tests, but is not the root cause of high uric acid, the statement is too absolute. High uric acid is mainly caused by increased uric acid production and decreased uric acid excretion. 1. Increased uric acid production: food-induced uric acid production is proportional to the purine content of the food, intake of animal offal, thick broth, high fructose drinks and other high-purine foods, can lead to increased uric acid production. In addition, purine metabolic defects, purine nucleoside decomposition accelerated, can also cause increased uric acid production. 2. Decreased excretion of uric acid: reduced glomerular filtration rate, certain drugs or substances such as aspirin, can cause uric acid reabsorption through the renal tubules to increase, resulting in increased blood uric acid. Daily drinking less water, urate can not be effectively dissolved, more likely to lead to the accumulation of uric acid in the body, increasing uric acid content. For people with high uric acid, it is recommended to increase the amount of water consumed, drinking up to 2,000 milliliters of water a day, while actively seeking medical treatment as prescribed by the doctor. It is recommended that patients with elevated uric acid go to the Department of Rheumatology and Immunology of a regular hospital for detailed consultation and standardized treatment as prescribed by the doctor.
