Drinking black tea urine usually does not turn red tea color. Black tea is a healthy beverage and even if consumed in excess, it will not cause the urine to turn red. If there is a situation where the urine turns red, it is considered to be due to disease factors, such as urinary tract infections, stones and so on. Due to the mucous membrane of the urinary system organs stimulated by inflammation can cause erosion, bleeding, resulting in red tea-colored urine. For urinary stones, due to the irregularity of the stone, it may cut through the mucous membrane of the genitourinary tract, resulting in causing the urine to become red in color. In addition, for the urinary system tumor, tuberculosis and other diseases, may also lead to red urine. Therefore, it is recommended to go to the hospital in time to see a doctor to clarify the specific diagnosis and then carry out targeted treatment.
