Factors such as narrow tube internal diameter, longer feeding tubes, tube tip location, slow feeding infusion rates, and formation of EN formula precipitate from contact with acidic gastric secretions contribute to the risk of tube clogging.

Before a medication in a solid dosage form is administered through a feeding tube, it should be determined if the medication is suitable for manipulation, such as crushing a tablet or opening a capsule.

Obstruction in feeding tubes was reported in 95% of the admixtures with incompatibility.
Managing the schedule of administration of nutrition and medication, and giving enough interval time between medications will theoretically reduce the incidence of medication-nutrition interactions, and diminish incompatibilities that cause obstructions.

Those recovering after serious illnesses such as Covid-19 often need significant rehabilitation because of profound weakness and loss of muscle mass. Emerging data highlights the prevalence of inadequate nutrition therapy and malnutrition, which is likely contributing to these long-lasting effects.
