Color: The color of urine can reflect the water and nutrition intake of the body. Healthy urine should be light yellow or transparent. If the urine is dark or shows other colors, it may be a sign of dehydration, drug abuse or other diseases.
Smell: The smell of healthy urine should be light. If urine smells bad, it may be a sign of infection or other diseases.
Quantity and frequency: Under normal circumstances, the amount of urine discharged by people every day and the frequency of urination are stable. If the urine volume or frequency changes, it may be a sign of physical problems.
Texture and shape: Under normal circumstances, urine should be a uniform liquid without clots or foreign bodies. If there is blood, pus or other abnormal substances in urine, it may be a sign of physical problems.
In short, observing your urine can provide some information about your health, but it can't completely replace the doctor's examination and diagnosis. If you find abnormal urine, you'd better see a doctor.
