The pH of urine, or pH 7, is a normal range, not a state of disease, and is not a cause for undue concern. The pH of urine is a dynamic change that fluctuates with the body’s diet, water intake and holding urine or with the occurrence of diluted urine. The pH fluctuation of urine between 4.5 and 8 is normal and is not a disease state. When drinking some medications, such as vitamin C, may cause the pH of urine to decrease; taking medications such as sodium bicarbonate may cause the pH of urine to increase. Changes in pH can also occur when urine is not urinated for a long period of time in a concentrated state, and changes in acidity can occur. These are in the process of dynamic changes, as long as they are not accompanied by any abnormalities of urinary tract urination, such as frequent urination, urgent urination, painful urination, bleeding and other changes, there is generally no need to deal with them, and it is enough to maintain a certain amount of water appropriately and observe dynamically.
