Hello, it is normal for your urine to turn red after eating red-fleshed dragon fruit. This occurs primarily because the pigment molecules in red-fleshed dragon fruit are relatively small and can pass through the kidneys into the urine, resulting in reddish-colored urine—a phenomenon clinically termed “pigmenturia.” Patients typically experience no discomfort, and routine urinalysis reveals no red blood cells in the urine. We hope this information is helpful to you. Wishing you a pleasant and healthy life!
