Most inpatients require a bowel regimen. Our patients typically have most of the risk factors for #constipation!
#Constipation is more about symptoms than frequency! 🚽

It’s also a *symptom* (like chest pain), so need to figure out what’s causing it and treat accordingly.
Inpatient #constipation is associated with worse 🏥 outcomes.
