1, eating red pitaya is a completely normal phenomenon, except red pitaya, such as red watermelon or rifampicin, which may make the urine red after taking it.

2. The specific reason is that it contains a lot of red pigments. This kind of red pigment can't be digested and absorbed by the human body, so it will be discharged in the urine in its original form, which will easily make the urine turn red and look like hematuria.

3. In this case, generally stop eating red drugs and food, and the urine color will return to normal after 0.5- 1 day, and there is no need to go to the hospital.
