What is a common side effect of tube feeding?

Diarrhea is a common side effect of tube feeding due to several factors related to the composition of the feeding solution and the body's response to enteral nutrition. Tube feeding solutions often contain high amounts of carbohydrates and can be osmotically active, which may lead to increased stool output as the body struggles to absorb the nutrients efficiently. Additionally, tube feeding bypasses the normal pharyngeal and esophageal phases of swallowing, altering gastrointestinal function and sometimes leading to rapid transit through the intestines, which can further contribute to diarrhea.

This side effect can be particularly pronounced if the feeding is initiated too quickly or if the patient has pre-existing gastrointestinal issues, such as infections or inflammatory conditions that affect absorption. Proper management of tube feeding, including gradual initiation and monitoring for tolerance, can help mitigate this side effect.

While constipation, dehydration, and nausea are potential issues associated with tube feeding, they are typically less common than diarrhea, which is why it is often highlighted in discussions of tube feeding complications.
