Full Definition

Artificial nutrition and hydration (ANH) encompasses feeding tubes (nasogastric, PEG — percutaneous endoscopic gastrostomy) and IV fluid administration that provide nutrition and/or fluids when a person can no longer eat or drink independently and adequately.

ANH has clear benefits in certain circumstances: short-term NG tube use following stroke or surgery while swallowing is being treated, PEG tube use in younger patients with adequate function, and IV hydration to manage medication side effects or reversible dehydration.

However, in advanced dementia, late-stage terminal illness, and end-stage organ failure, the evidence does not support that ANH prolongs life or improves quality of life. In advanced dementia specifically, multiple studies have found that tube feeding does not prevent aspiration pneumonia, does not improve nutritional status, does not prevent pressure ulcers, and does not improve survival compared to careful hand feeding. It may actually increase suffering through aspiration, agitation, and physical discomfort from the tube.

For Texas families, the decision about artificial nutrition is a profound one that should ideally be addressed in advance directives before a crisis. Both the Texas Directive to Physicians and the Healthcare Proxy can specify the person’s wishes about artificial nutrition. Understanding the evidence — particularly in advanced dementia — helps families make informed decisions aligned with their loved one’s values.
