Constipation is the decreased passage of stool characterized by infrequent bowel movements, hard stool, a sensation of abdominal bloating or cramping, straining with bowel movements, and the feeling of incomplete evacuation. Constipation occurs in 43%–58% of people with a diagnosis of cancer.
For constipation, standards of care are based on established evidence-based practice.
• Constipation is the decreased passage of stool characterized by infrequent bowel movements, hard stool, a sensation of abdominal bloating or cramping, straining with bowel movements, and the feeling of incomplete evacuation.
• Constipation occurs in 43%–58% of people with a diagnosis of cancer.
• Assessment should review the normal pattern of elimination, including frequency, time of day, and stool characteristics (e.g., color, consistency, odor).
• Advise hydration with at least two liters of caffeine-free fluids daily.
• Opioid-induced constipation treatment should include initial treatment with osmotic (e.g., polyethylene glycol, magnesium citrate) or stimulant (e.g., senna, bisacodyl) laxatives in addition to lifestyle education.
• For persistent opioid-induced constipation that has not responded to a bowel regimen, consider treatment with a peripherally acting mu-opioid receptor antagonist (PAMORA) (i.e., methylnaltrexone, naldemedine, or naloxegol) in addition to the existing bowel regimen. For those unable to take other forms of PAMORAs, subcutaneous methylnaltrexone may present an effective option.
• Non–opioid-related constipation should be treated with osmotic or stimulant laxatives in addition to education about lifestyle choices.
• Avoid dehydration, inactivity, or poor fiber intake, which are risk factors for constipation.
