Introduction
It is normal for urine to turn red after eating red-fleshed dragon fruit. Red-fleshed dragon fruit contains a natural pigment called betacyanin. After passing through the digestive system, part of this pigment is absorbed into the bloodstream, while the remainder is excreted from the body through urine and feces. When betacyanin passes through the kidneys and enters the urine, it can cause the urine to appear red or pink.
Generally, red urine after eating red-fleshed dragon fruit is a normal phenomenon. However, if discomfort symptoms occur, it may indicate an abnormal condition. It is recommended that patients promptly visit a hospital and follow medical advice for treatment. Specific analysis is as follows:
Red-fleshed dragon fruit contains a natural pigment called betacyanin. After passing through the human digestive system, part of this pigment is absorbed into the bloodstream, while the remainder is excreted from the body through urine and feces. When betacyanin passes through the kidneys and enters the urine, it can cause the urine to appear red or pink. This type of urine discoloration caused by red-fleshed dragon fruit is usually temporary and typically resolves within one to two days after stopping consumption of the fruit.
However, if the red discoloration of urine persists for a prolonged period or is accompanied by other symptoms such as frequent urination, urgency, or pain during urination, it may not be due to consuming red-fleshed dragon fruit but could instead indicate an issue with the urinary system. In such cases, prompt medical evaluation is necessary to determine the underlying cause and receive appropriate treatment.
In daily life, maintaining good dietary habits helps support overall health.
