The urine is dark brown. What's going on?

The reasons for the dark brown color of urine are as follows: 1. If you eat red pitaya in the near future, due to the red pigment contained in pitaya, it can cause the urine to turn dark brown after being filtered out by the kidneys, generally not accompanied by other uncomfortable manifestations. The number of red blood cells is normal during routine urine examination. After stopping using pitaya, the color of urine can gradually return to normal. 2. When routine urine test is carried out, if the number of red blood cells is significantly increased, the number of white blood cells is also abnormal, and it is also accompanied by frequent urination, urgency, urinary pain and other manifestations. It may be caused by acute urinary tract infection, and antibiotics should be used in time for treatment.
