Can eating watermelon cause red-colored stools?

In the general population with normal digestive function, moderate consumption of watermelon generally does not cause red-colored stools. However, if consumed in excessive amounts or if there are digestive problems, stools may turn red.

Individuals with better digestive function are less likely to experience red-colored stools caused by eating watermelon, as their bodies can more effectively digest and absorb the nutrients in watermelon. If the change in stool color persists or is accompanied by other symptoms such as abdominal pain, diarrhea, or blood in the stool, it may indicate an underlying health issue, such as gastrointestinal bleeding or hemorrhoids. In such cases, the reddening of the stool is not caused by watermelon, and medical attention is required for further evaluation and treatment.

When large amounts of watermelon are consumed, the lycopene and other pigments it contains may not be completely absorbed by the body in time. Residual pigments may be excreted in the feces, sometimes causing the stool to appear slightly red or orange. Individuals with indigestion, intestinal diseases, or other digestive system issues may experience impaired metabolism of food pigments, resulting in more noticeable changes in stool color.

In daily diet, balanced intake of various foods and avoiding excessive consumption of any single food item can help maintain a healthy digestive system. Avoid overconsumption of raw, cold, spicy, or irritating foods, and maintain healthy lifestyle habits.
