Why is the urine acidity and alkalinity high?

Regarding the issue of acidity and alkalinity in urine routine examination, many people do not pay much attention to it in life. However, under normal circumstances, the acidity and alkalinity of human urine is an acidic liquid. If the acidity and alkalinity in urine routine examination is high, in addition to being caused by some diseases, it is also closely related to daily diet. However, the single result of acidity and alkalinity determination does not have much clinical significance, and it must be monitored in combination with changes in the patient's condition.

1. The normal pH value of humans is between 5.5-7.4. Normal urine is generally an acidic liquid, which is usually expressed using the pH method to indicate the acidity or alkalinity of the solution. A pH less than 7 is acidic, 7 is neutral, and greater than 7 is alkaline.

2. If you are a vegetarian, the organic acids in plants will produce less acidic substances after oxidation in the body, so less acidic substances will be excreted in the urine, and the alkaline groups will increase, making the urine alkaline. Stones formed by oxalate, phosphate, and carbonate often appear in alkaline urine; urine is also alkaline in cases of cystitis, alkali poisoning, renal tubular acidosis, and urinary tract infection; urine that has been left for too long, and concentrated hematuria can also make urine alkaline.

3. Urine acid-base determination often has no obvious clinical significance when used independently. It is generally used in combination with other items to comprehensively judge changes in the patient's condition and for monitoring.

4. If the pH value of urine is too high, it means that the excretion and reabsorption functions of the kidneys are impaired. Excessive alkaline substances are excreted from the urine, which may cause a relatively excessive amount of acidic substances in the body and form an acidic constitution. However, the pH value of urine is also related to what you eat the day before, so it cannot explain the problem accurately. It requires long-term examination and analysis to be determined.
