It is normal to have reddish colored stool after eating dragon fruit. Because the anthocyanin content in dragon fruit is relatively high, this natural pigment is usually more water-soluble, the human body is not able to completely dissolve and absorb this pigment, so after eating dragon fruit, the red pigment will be excreted along with urine and stool, which is a normal phenomenon. Red stools caused by eating dragon fruit usually return to normal after 24 hours, so no special treatment is needed. If the patient’s red stool does not improve, it is recommended to go to the regular hospital in time, after clarifying the cause of the disease, under the guidance of the doctor to carry out targeted treatment.
