A urine pH of 5.0 is within the normal range and is not low.
The acidity of urine, or pH, is weakly acidic under normal conditions, about 6.5, and fluctuates from 4.5 to 8.0. A variety of causes can lead to an abnormal urine pH.
Possible causes of increased urinary pH include: metabolic or respiratory alkalosis; prolonged vomiting; oxalate-phosphate lithiasis; infectious cystitis; and the application of alkaline drugs such as sodium lactate and sodium bicarbonate.
Possible causes of decreased urinary pH include: metabolic or respiratory acidosis; diabetic ketoacidosis; severe diarrhea and starvation; urinary tract tuberculosis; and application of acidic medications such as vitamin c and ammonium chloride.
Urine pH 5.0 belongs to the normal range, but if the patient has any discomfort, it is recommended to consult a regular hospital and standardize the treatment under the guidance of a physician.
