The light red color of urine in women may have some relationship with food or drugs, or it may be caused by urinary tract infection, stones, tumors, kidney disease and so on. If you eat some food or drugs that contain red pigment, it can lead to red urine color, such as red dragon fruit or rifampicin, which can return to normal after drinking a lot of water. Urinary system diseases can also lead to red urine color, such as urinary system infections, urinary stones, tumors, tuberculosis, kidney disease and so on. Excluding the reddish color of urine caused by physiological factors, you need to go to the hospital, complete the relevant examinations to identify the cause of hematuria, and then give treatment.
