1. Check the color of urine: if the urine is yellow, it may be caused by lack of water; if it is red or brown, it may be caused by diseases such as kidney disease.
2. Check the smell of urine: If the urine has a pungent smell, it may be caused by infection or other health problems.
3. Check the clarity of urine: Clear urine usually means good health. If there is precipitation or turbidity, it may be caused by infection or other health problems.
4. Check the pH value of urine: The pH value of urine is usually between 5 and 9. If it exceeds this range, it may be caused by some pathological conditions.
5. Check the contents of urine protein, glucose, ketone bodies, etc.: These indicators are helpful to detect health problems such as diabetes and kidney disease.
In short, paying attention to urine can help you find health problems and treat them as soon as possible, but it should be noted that these indicators are not the only basis for diagnosing diseases, and it is best to combine the advice and examination of professional doctors to maintain your health.
