Opioid-induced constipation

Opioid-induced constipation is an adverse gastrointestinal disorder characterized by new or worsening constipation symptoms triggered by the initiation, alteration, or dose escalation of opioid analgesic therapy It primarily affects the enteric nervous system and digestive tract in acute and chronic pain populations, including individuals with cancer-related or noncancer pain Pathophysiologically, exogenous opioids bind to peripheral mu-opioid receptors within the bowel wall, resulting in suppre...

Opioid-induced constipation is an adverse gastrointestinal disorder characterized by new or worsening constipation symptoms triggered by the initiation, alteration, or dose escalation of opioid analgesic therapy Clinically, this manifests as reduced stool frequency, hard or lumpy stools, excessive straining, abdominal distension, and a persistent sensation of incomplete rectal evacuation that typically does not resolve with tolerance
