First the patient needs to determine if the symptom is true blood in urine.
In patients with small kidney stones, the hematuria may stop because the stones are expelled.
Some patients consume too much food containing a lot of pigment in a short period of time, which may lead to a change in the color of urination and bowel movements.
For example, eating too much red heart dragon fruit may cause the urine to turn red. Patients need not worry excessively, and if they urinate blood again, it is sufficient to seek prompt medical examination.
