Uric acid is the end product of the body’s purine metabolism in the body, for a normal body uric acid production and excretion are equal, so that uric acid is maintained within the normal range. In case of low uric acid, firstly, it is considered to be caused by low intake of purine, which is caused by eating little and often vegetarian food in the course of daily diet. Secondly, in patients with liver disease, low uric acid is caused by the effect on the metabolism of purines. Again, patients with wasting diseases, such as diarrhea, consume too much uric acid causing a decrease in uric acid in the blood. Therefore, it is very important for the organism to have good dietary habits in daily life, pay attention to balanced nutrition in the diet, and if low uric acid leads to the occurrence of pathological diseases, promptly go to a regular hospital for examination and identify the cause of the disease and then treat it symptomatically under the guidance of a doctor. In daily life, we should actively exercise to prevent the occurrence of diseases.
